Field Detail

AggregateRuleTag

public final transient org.eigenbase.util.property.StringProperty AggregateRuleTag

String property that is the AggRule element's tag value.

Normally, this property is not set by a user.

AggregateRules

public final transient org.eigenbase.util.property.StringProperty AggregateRules

String property containing the name of the file which defines the rules for recognizing an aggregate table. Can be either a resource in the Mondrian jar or a URL.

The default value is "/DefaultRules.xml", which is in the mondrian.rolap.aggmatcher package in Mondrian.jar.

Normally, this property is not set by a user.

AlertNativeEvaluationUnsupported

public final transient org.eigenbase.util.property.StringProperty AlertNativeEvaluationUnsupported

Alerting action to take in case native evaluation of a function is enabled but not supported for that function's usage in a particular query. (No alert is ever raised in cases where native evaluation would definitely have been wasted effort.)

Recognized actions:

• OFF: do nothing (default action, also used if unrecognized action is specified)
• WARN: log a warning to RolapUtil logger
• ERROR: throw an instance of NativeEvaluationUnsupportedException

CaseSensitive

public final transient org.eigenbase.util.property.BooleanProperty CaseSensitive

Boolean property that controls whether the MDX parser resolves uses case-sensitive matching when looking up identifiers. The default is false.

CatalogURL

public final transient org.eigenbase.util.property.StringProperty CatalogURL

Property that contains the URL of the catalog to be used by CmdRunner and XML/A Test.

ChooseAggregateByVolume

public final transient org.eigenbase.util.property.BooleanProperty ChooseAggregateByVolume

Boolean property that controls whether aggregate tables are ordered by their volume or row count.

If true, Mondrian uses the aggregate table with the smallest volume (number of rows multiplied by number of columns); if false, Mondrian uses the aggregate table with the fewest rows.

CompareSiblingsByOrderKey

public final transient org.eigenbase.util.property.BooleanProperty CompareSiblingsByOrderKey

Boolean property that controls whether sibling members are compared according to order key value fetched from their ordinal expression. The default is false (only database ORDER BY is used).

CrossJoinOptimizerSize

public final transient org.eigenbase.util.property.IntegerProperty CrossJoinOptimizerSize

Property that defines when to apply the crossjoin optimization algorithm.

If a crossjoin input list's size is larger than this property's value and the axis has the "NON EMPTY" qualifier, then the crossjoin non-empty optimizer is applied. Setting this value to '0' means that for all crossjoin input lists in non-empty axes will have the optimizer applied. On the other hand, if the value is set larger than any possible list, say Integer.MAX_VALUE, then the optimizer will never be applied.

DataSourceResolverClass

public final transient org.eigenbase.util.property.StringProperty DataSourceResolverClass

Property that defines the name of the plugin class that resolves data source names to DataSource objects. The class must implement the DataSourceResolver interface. If not specified, the default implementation uses JNDI to perform resolution.

Example:

mondrian.spi.dataSourceResolverClass=mondrian.spi.impl.JndiDataSourceResolver

DisableCaching

public final transient org.eigenbase.util.property.BooleanProperty DisableCaching

Boolean property that controls whether a RolapStar's aggregate data cache is cleared after each query. If true, no RolapStar will cache aggregate data from one query to the next (the cache is cleared after each query).

EnableCacheHitCounters

public final transient org.eigenbase.util.property.BooleanProperty EnableCacheHitCounters

Deprecated. This property is no longer used, and will be removed in mondrian-4.0.

Property that controls whether aggregation cache hit / miss counters will be enabled.

Note that this will affect performance due to existence of sync blocks.

EnableDrillThrough

public final transient org.eigenbase.util.property.BooleanProperty EnableDrillThrough

If disabled, Mondrian will throw an exception if someone attempts to perform a drillthrough of any kind.

EnableExpCache

public final transient org.eigenbase.util.property.BooleanProperty EnableExpCache

Boolean property that controls whether to use a cache for frequently evaluated expressions. With the cache disabled, an expression like Rank([Product].CurrentMember, Order([Product].MEMBERS, [Measures].[Unit Sales])) would perform many redundant sorts. The default is true.

EnableGroupingSets

public final transient org.eigenbase.util.property.BooleanProperty EnableGroupingSets

Property that defines whether to generate SQL queries using the GROUPING SETS construct for rollup. By default it is not enabled.

Ignored on databases which do not support the GROUPING SETS construct (see Dialect.supportsGroupingSets()).

EnableNativeCrossJoin

public final transient org.eigenbase.util.property.BooleanProperty EnableNativeCrossJoin

If enabled some NON EMPTY CrossJoin will be computed in SQL.

EnableNativeFilter

public final transient org.eigenbase.util.property.BooleanProperty EnableNativeFilter

If enabled some Filter() will be computed in SQL.

EnableNativeNonEmpty

public final transient org.eigenbase.util.property.BooleanProperty EnableNativeNonEmpty

If enabled some NON EMPTY set operations like member.children, level.members and member descendants will be computed in SQL.

EnableNativeTopCount

public final transient org.eigenbase.util.property.BooleanProperty EnableNativeTopCount

If enabled some TopCount will be computed in SQL.

EnableNonEmptyOnAllAxis

public final transient org.eigenbase.util.property.BooleanProperty EnableNonEmptyOnAllAxis

Boolean property that controls whether each query axis implicit has the NON EMPTY option set. The default is false.

EnableRolapCubeMemberCache

public final transient org.eigenbase.util.property.BooleanProperty EnableRolapCubeMemberCache

Property that determines whether to cache RolapCubeMember objects, each of which associates a member of a shared hierarchy with a particular cube in which it is being used.

The default is true, that is, use a cache. If you wish to use the member cache control aspects of CacheControl, you must set this property to false.

RolapCubeMember has recently become more lightweight to construct, and we may obsolete this cache and this property.

EnableTotalCount

public final transient org.eigenbase.util.property.BooleanProperty EnableTotalCount

If enabled, first row in the result of an XML/A drill-through request will be filled with the total count of rows in underlying database.

EnableTriggers

public final transient org.eigenbase.util.property.BooleanProperty EnableTriggers

Boolean property that controls whether to notify the Mondrian system when a property value changes.

This allows objects dependent on Mondrian properties to react (that is, reload), when a given property changes via, say, MondrianProperties.instance().populate(null) or MondrianProperties.instance().QueryLimit.set(50).

ExpCompilerClass

public final transient org.eigenbase.util.property.StringProperty ExpCompilerClass

Property that defines the name of the class used to compile scalar expressions.

If the value is non-null, it is used by the ExpCompiler.Factory to create the implementation.

To test that for all test MDX queries that all functions can handle requests for ITERABLE, LIST and MUTABLE_LIST evalutation results, use the following:

mondrian.calc.ExpCompiler.class=mondrian.olap.fun.ResultStyleCompiler

ExpandNonNative

public final transient org.eigenbase.util.property.BooleanProperty ExpandNonNative

If this property is true, when looking for native evaluation of an expression, Mondrian will expand non-native sub-expressions into lists of members.

FilterChildlessSnowflakeMembers

public final transient org.eigenbase.util.property.BooleanProperty FilterChildlessSnowflakeMembers

Property that defines whether to generate joins to filter out members in a snowflake dimension that do not have any children.

If true (the default), some queries to query members of high levels snowflake dimensions will be more expensive. If false, and if there are rows in an outer snowflake table that are not referenced by a row in an inner snowflake table, then some queries will return members that have no children.

Our recommendation, for best performance, is to remove rows outer snowflake tables are not referenced by any row in an inner snowflake table, during your ETL process, and to set this property to false.

FoodmartJdbcURL

public final transient org.eigenbase.util.property.StringProperty FoodmartJdbcURL

Property containing the JDBC URL of the FoodMart database. The default value is to connect to an ODBC data source called "MondrianFoodMart".

To run the test suite, first load the FoodMart data set into the database of your choice. Then set the driver.classpath, mondrian.foodmart.jdbcURL and mondrian.jdbcDrivers properties, by uncommenting and modifying one of the sections below. Put the JDBC driver jar into mondrian/testlib.

GenerateAggregateSql

public final transient org.eigenbase.util.property.BooleanProperty GenerateAggregateSql

Boolean property that controls whether to print the SQL code generated for aggregate tables.

If set, then as each aggregate request is processed, both the lost and collapsed dimension create and insert sql code is printed. This is for use in the CmdRunner allowing one to create aggregate table generation sql.

GenerateFormattedSql

public final transient org.eigenbase.util.property.BooleanProperty GenerateFormattedSql

Boolean property that controls pretty-print mode.

If true, the all SqlQuery SQL strings will be generated in pretty-print mode, formatted for ease of reading.

HighCardChunkSize

public final transient org.eigenbase.util.property.IntegerProperty HighCardChunkSize

Property that establishes the amount of chunks for querying cells involving high-cardinality dimensions. Should prime with mondrian.result.limit.

IgnoreInvalidMembers

public final transient org.eigenbase.util.property.BooleanProperty IgnoreInvalidMembers

Property that defines whether non-existent member errors should be ignored during schema load. If so, the non-existent member is treated as a null member.

IgnoreInvalidMembersDuringQuery

public final transient org.eigenbase.util.property.BooleanProperty IgnoreInvalidMembersDuringQuery

Property that defines whether non-existent member errors should be ignored during query validation. If so, the non-existent member is treated as a null member.

IgnoreMeasureForNonJoiningDimension

public final transient org.eigenbase.util.property.BooleanProperty IgnoreMeasureForNonJoiningDimension

Property that defines whether to ignore measure when non joining dimension is in the tuple during aggregation.

If there are unrelated dimensions to a measure in context during aggregation, the measure is ignored in the evaluation context. This behaviour kicks in only if the cubeusage for this measure has IgnoreUnrelatedDimensions attribute set to false.

For example, Gender doesn't join with [Warehouse Sales] measure.

With mondrian.olap.agg.IgnoreMeasureForNonJoiningDimension=true Warehouse Sales gets eliminated and is ignored in the aggregate value.

[Store Sales] + [Warehouse Sales] SUM({Product.members * Gender.members}) 7,913,333.82

With mondrian.olap.agg.IgnoreMeasureForNonJoiningDimension=false Warehouse Sales with Gender All level member contributes to the aggregate value.

[Store Sales] + [Warehouse Sales] SUM({Product.members * Gender.members}) 9,290,730.03

On a report where Gender M, F and All members exist a user will see a large aggregated value compared to the aggregated value that can be arrived at by suming up values against Gender M and F. This can be confusing to the user. This feature can be used to eliminate such a situation.

IterationLimit

public final transient org.eigenbase.util.property.IntegerProperty IterationLimit

Integer property indicating the maximum number of iterations allowed when iterating over members to compute aggregates. A value of 0 (the default) indicates no limit.

Iterations

public final transient org.eigenbase.util.property.IntegerProperty Iterations

Not documented.

JdbcDrivers

public final transient org.eigenbase.util.property.StringProperty JdbcDrivers

Property containing a list of JDBC drivers to load automatically. Must be a comma-separated list of class names, and the classes must be on the class path.

JdbcFactoryClass

public final transient org.eigenbase.util.property.StringProperty JdbcFactoryClass

Property that defines the JdbcSchema factory class which determines the list of tables and columns of a specific datasource.

See Also:

JdbcSchema

LocalePropFile

public final transient org.eigenbase.util.property.StringProperty LocalePropFile

String property that holds the name of the class whose resource bundle is to be used to for this schema. For example, if the class is com.acme.MyResource, mondrian will look for a resource bundle called com/acme/MyResource_<i>locale</i>.properties on the class path. (This property has a confusing name because in a previous release it actually held a file name.)

Used for the LocalizingDynamicSchemaProcessor; see Internationalization for more details.

Default value is null.

MaxConstraints

public final transient org.eigenbase.util.property.IntegerProperty MaxConstraints

Max number of constraints in a single 'IN' SQL clause.

This value may be variant among database prodcuts and their runtime settings. Oracle, for example, gives the error "ORA-01795: maximum number of expressions in a list is 1000".

Recommended values:

• Oracle: 1,000
• DB2: 2,500
• Other: 10,000

MaxEvalDepth

public final transient org.eigenbase.util.property.IntegerProperty MaxEvalDepth

Boolean property that defines the maximum number of passes allowable while evaluating an MDX expression.

If evaluation exceeds this depth (for example, while evaluating a very complex calculated member), Mondrian will throw an error.

MaxRows

public final transient org.eigenbase.util.property.IntegerProperty MaxRows

Property that defines limit on the number of rows returned by XML/A drill through request.

MemoryMonitor

public final transient org.eigenbase.util.property.BooleanProperty MemoryMonitor

Property that defines whether the MemoryMonitor should be enabled. By default it is disabled; memory monitor is not available before Java version 1.5.

MemoryMonitorClass

public final transient org.eigenbase.util.property.StringProperty MemoryMonitorClass

Property that defines the name of the class used as a memory monitor.

If the value is non-null, it is used by the MemoryMonitorFactory to create the implementation.

MemoryMonitorThreshold

public final transient org.eigenbase.util.property.IntegerProperty MemoryMonitorThreshold

Property that defines the default MemoryMonitor percentage threshold. If enabled, when Java's memory monitor detects that post-garbage collection is above this value, notifications are generated.

NativizeMaxResults

public final transient org.eigenbase.util.property.IntegerProperty NativizeMaxResults

Property that controls the maximum number of results contained in a NativizeSet result set.

If the number of tuples contained in the result set exceeds this value Mondrian throws a LimitExceededDuringCrossjoin error.

NativizeMinThreshold

public final transient org.eigenbase.util.property.IntegerProperty NativizeMinThreshold

Property that controls minimum expected cardinality required in order for NativizeSet to natively evaluate a query.

If the expected cardinality falls below this level the query is executed non-natively.

It is possible for the actual cardinality to fall below this threshold even though the expected cardinality falls above this threshold. In this case the query will be natively evaluated.

NeedDimensionPrefix

public final transient org.eigenbase.util.property.BooleanProperty NeedDimensionPrefix

Property determines if elements of dimension (levels, hierarchies, members) need to be prefixed with dimension name in MDX query.

For example when the property is true, the following queries will error out. The same queries will work when this property is set to false.

select {[M]} on 0 from sales

select {[USA]} on 0 from sales

select {[USA].[CA].[Santa Monica]} on 0 from sales

When the property is set to true, any query where elements are prefixed with dimension name as below will work

select {[Gender].[F]} on 0 from sales

select {[Customers].[Santa Monica]} on 0 from sales

Please note that this property does not govern the behaviour wherein

[Gender].[M]

is resolved into a fully qualified

[Gender].[M]

In a scenario where the schema is very large and dimensions have large number of members a MDX query that has a invalid member in it will cause mondrian to to go through all the dimensions, levels, hierarchies, members and properties trying to resolve the element name. This behavior consumes considerable time and resources on the server. Setting this property to true will make it fail fast in a scenario where it is desirable.

NullDenominatorProducesNull

public final transient org.eigenbase.util.property.BooleanProperty NullDenominatorProducesNull

Property that defines the behavior of division if the denominator evaluates to zero.

If false (the default), if a division has a non-null numerator and a null denominator, it evaluates to "Infinity", which conforms to MSAS behavior.

If true, the result is null if the denominator is null. Setting to true enables the old semantics of evaluating this to null; this does not conform to MSAS, but is useful in some applications.

NullMemberRepresentation

public final transient org.eigenbase.util.property.StringProperty NullMemberRepresentation

Property that determines how a null member value is represented in the result output.

AS 2000 shows this as empty value

AS 2005 shows this as "(null)" value

OptimizePredicates

public final transient org.eigenbase.util.property.BooleanProperty OptimizePredicates

Boolean property that determines whether Mondrian optimizes predicates.

If true, Mondrian may retrieve a little more data than specified in MDX query and cache it for future use. For example, if you ask for data on 48 states of the United States for 3 quarters of 2011, Mondrian will round out to all 50 states and all 4 quarters. If false, Mondrian still optimizes queries that involve all members of a dimension.

PropertyValueMapFactoryClass

public final transient org.eigenbase.util.property.StringProperty PropertyValueMapFactoryClass

Property that defines the name of the factory class used to create maps of member properties to their respective values.

If the value is non-null, it is used by the PropertyValueFactory to create the implementation. If unset, RolapMemberBase.DefaultPropertyValueMapFactory will be used.

QueryFileDirectory

public final transient org.eigenbase.util.property.StringProperty QueryFileDirectory

Property defining where the test XML files are.

QueryFilePattern

public final transient org.eigenbase.util.property.StringProperty QueryFilePattern

Property that defines a pattern for which test XML files to run. Pattern has to match a file name of the form: querywhatever.xml in the directory.

Example:

mondrian.test.QueryFilePattern=queryTest_fec[A-Za-z0-9_]*.xml

QueryLimit

public final transient org.eigenbase.util.property.IntegerProperty QueryLimit

Maximum number of simultaneous queries the system will allow.

Oracle fails if you try to run more than the 'processes' parameter in init.ora, typically 150. The throughput of Oracle and other databases will probably reduce long before you get to their limit.

QueryTimeout

public final transient org.eigenbase.util.property.IntegerProperty QueryTimeout

Property that defines the timeout value (in seconds) for queries. A value of 0 (the default), indicates no timeout.

ReadAggregates

public final transient org.eigenbase.util.property.BooleanProperty ReadAggregates

Boolean property that determines whether Mondrian should read aggregate tables.

If set to true, then Mondrian scans the database for aggregate tables. Unless mondrian.rolap.aggregates.Use is set to true, the aggregates found will not be used.

ResultLimit

public final transient org.eigenbase.util.property.IntegerProperty ResultLimit

Integer property that, if set to a value greater than zero, limits the maximum size of a result set.

RolapConnectionShepherdNbThreads

public final transient org.eigenbase.util.property.IntegerProperty RolapConnectionShepherdNbThreads

Maximum number of user threads per Mondrian server instance. Defaults to 10.

RolapConnectionShepherdThreadPollingInterval

public final transient org.eigenbase.util.property.IntegerProperty RolapConnectionShepherdThreadPollingInterval

Property that defines the interval value (in miliseconds) between polling operations performed by the RolapConnection shepherd thread. This controls query timeouts and calcelation, so a small value (a few miliseconds) is best. Setting this to a value higher than mondrian.rolap.queryTimeout will result the timeout not being enforced as expected. Defaults to 1000ms.

RollupAnalyzerNumberThreads

public final transient org.eigenbase.util.property.IntegerProperty RollupAnalyzerNumberThreads

Property which defines how many threads are created in order to analyze possible segment rollup opportunities. This value defaults to 4, but it can be set to a higher value on big multi-core systems.

SegmentCache

public final transient org.eigenbase.util.property.StringProperty SegmentCache

Property which defines which SegmentCache implementation to use. Specify the value as a fully qualified class name, such as org.example.SegmentCacheImpl where SegmentCacheImpl is an implementation of SegmentCache.

SolveOrderMode

public final transient org.eigenbase.util.property.StringProperty SolveOrderMode

Property that controls the behavior of solve order of calculated members and sets.

Valid values are "absolute" and "scoped" (the default). See SolveOrderMode for details.

SparseSegmentCountThreshold

public final transient org.eigenbase.util.property.IntegerProperty SparseSegmentCountThreshold

Property that, with SparseSegmentDensityThreshold, determines whether to choose a sparse or dense representation when storing collections of cell values in memory.

When storing collections of cell values, Mondrian has to choose between a sparse and a dense representation, based upon the possible and actual number of values. The density is actual / possible.

We use a sparse representation if (possible - countThreshold) * densityThreshold > actual

For example, at the default values (countThreshold = 1000, SparseSegmentDensityThreshold = 0.5), we use a dense representation for

• (1000 possible, 0 actual), or
• (2000 possible, 500 actual), or
• (3000 possible, 1000 actual).

Any fewer actual values, or any more possible values, and Mondrian will use a sparse representation.

SparseSegmentDensityThreshold

public final transient org.eigenbase.util.property.DoubleProperty SparseSegmentDensityThreshold

Property that, with SparseSegmentCountThreshold, determines whether to choose a sparse or dense representation when storing collections of cell values in memory.

SqlMemberSourceValuePoolFactoryClass

public final transient org.eigenbase.util.property.StringProperty SqlMemberSourceValuePoolFactoryClass

Property that defines the name of the class used in SqlMemberSource to pool common values.

If the value is non-null, it is used by the SqlMemberSource.ValueMapFactory to create the implementation. If it is not set, then SqlMemberSource.NullValuePoolFactory will be used, meaning common values will not be pooled.

SsasCompatibleNaming

public final transient org.eigenbase.util.property.BooleanProperty SsasCompatibleNaming

Property that defines whether to enable new naming behavior.

If true, hierarchies are named [Dimension].[Hierarchy]; if false, [Dimension.Hierarchy].

TestClass

public final transient org.eigenbase.util.property.StringProperty TestClass

String property that determines which test class to run.

This is the name of the class. It must either implement junit.framework.Test or have a method public [static] junit.framework.Test suite().

Example:

mondrian.test.Class=mondrian.test.FoodMartTestCase

TestName

TestConnectString

public final transient org.eigenbase.util.property.StringProperty TestConnectString

Property containing the connect string which regresssion tests should use to connect to the database.

Format is specified in Util.parseConnectString(String).

TestExpDependencies

public final transient org.eigenbase.util.property.IntegerProperty TestExpDependencies

Integer property that controls whether to test operators' dependencies, and how much time to spend doing it.

If this property is positive, Mondrian's test framework allocates an expression evaluator which evaluates each expression several times, and makes sure that the results of the expression are independent of dimensions which the expression claims to be independent of.

The default is 0.

TestHighCardinalityDimensionList

public final transient org.eigenbase.util.property.StringProperty TestHighCardinalityDimensionList

Property containing a list of dimensions in the Sales cube that should be treated as high-cardinality dimensions by the testing infrastructure. This allows us to run the full suite of tests with high-cardinality functionality enabled.

TestJdbcPassword

public final transient org.eigenbase.util.property.StringProperty TestJdbcPassword

Property containing the JDBC password of a test database. The default value is null, to cope with DBMSs that don't need this.

TestJdbcUser

public final transient org.eigenbase.util.property.StringProperty TestJdbcUser

Property containing the JDBC user of a test database. The default value is null, to cope with DBMSs that don't need this.

TestName

public final transient org.eigenbase.util.property.StringProperty TestName

String property that determines which tests are run.

This is a regular expression as defined by Pattern. If this property is specified, only tests whose names match the pattern in its entirety will be run.

See Also:

TestClass

TestSeed

public final transient org.eigenbase.util.property.IntegerProperty TestSeed

Seed for random number generator used by some of the tests.

Any value besides 0 or -1 gives deterministic behavior. The default value is 1234: most users should use this. Setting the seed to a different value can increase coverage, and therefore may uncover new bugs.

If you set the value to 0, the system will generate its own pseudo-random seed.

If you set the value to -1, Mondrian uses the next seed from an internal random-number generator. This is a little more deterministic than setting the value to 0.

TimeLimit

public final transient org.eigenbase.util.property.IntegerProperty TimeLimit

Property that returns the time limit for the test run in seconds. If the test is running after that time, it is terminated.

UseAggregates

public final transient org.eigenbase.util.property.BooleanProperty UseAggregates

Boolean property that controls whether Mondrian uses aggregate tables.

If true, then Mondrian uses aggregate tables. This property is queried prior to each aggregate query so that changing the value of this property dynamically (not just at startup) is meaningful.

Aggregates can be read from the database using the ReadAggregates property but will not be used unless this property is set to true.

VUsers

public final transient org.eigenbase.util.property.IntegerProperty VUsers

Not documented.

Warmup

public final transient org.eigenbase.util.property.BooleanProperty Warmup

Property that indicates whether this is a "warmup test".

WarnIfNoPatternForDialect

public final transient org.eigenbase.util.property.StringProperty WarnIfNoPatternForDialect

Property that controls if warning messages should be printed if a sql comparison tests do not contain expected sqls for the specified dialect. The tests are skipped if no expected sqls are found for the current dialect.

Possible values are the following:

• "NONE": no warning (default)
• "ANY": any dialect
• "ACCESS"
• "DERBY"
• "LUCIDDB"
• "MYSQL"
• ... and any Dialect enum in SqlPattern.Dialect

Specific tests can overwrite the default setting. The priority is:

• Settings besides "ANY" in mondrian.properties file
• < Any setting in the test
• < "ANY"

XmlaSchemaRefreshInterval

public final transient org.eigenbase.util.property.IntegerProperty XmlaSchemaRefreshInterval

Interval, in milliseconds, at which to refresh the list of XML/A catalogs. (Usually known as the datasources.xml file.)

It is not an active process; no threads will be created. It only serves as a rate limiter. The refresh process is triggered by requests to the doPost() servlet method.

Default value is 3000 milliseconds (3 seconds).

See also DynamicDatasourceXmlaServlet.
