OLAP DML Options by Category

OLAP DML options fall into the following general categories:

Options Related to Analytic Workspace Management

Table A-3, "Options Related to Working with Analytic Workspaces" lists the options that you might want to reset before you either create or attach an analytic workspace.

Table A-3 Options Related to Working with Analytic Workspaces

An option that contains the number of seconds that AW ATTACH with the if the WAIT keyword waits for an analytic workspace to become available for access.

DEFAULTAWSEGSIZE


An option that specifies the default maximum segment size for an analytic workspace created in your database session.


Multi-Language Support Options

You use the options outlined in Table A-4, "Multi-language Support Options", along with the $DEFAULT_LANGUAGE property, to create multi-language programs and applications.

Table A-4 Multi-language Support Options

Option Description

LOCK_LANGUAGE_DIMS


An option that specifies whether or not the value of the SESSION_NLS_LANGUAGE option can be changed.

SESSION_NLS_LANGUAGE


An option that is the name of the language used by Oracle OLAP throughout the session.

STATIC_SESSION_LANGUAGE


An option that controls whether or not Oracle OLAP keeps the value of the SESSION_NLS_LANGUAGE option synchronized with the value of the NLS_LANGUAGE option.


Aggregation Options

A number of options can impact aggregation as outlined in Table A-5, "Aggregation Options".

Table A-5 Aggregation Options

Option Description

MULTIPATHHIER


An option that specifies that a given cell that contains detail data can have more than one path into a cell that contains aggregated data.

POUTFILEUNIT


An option that identifies a destination for status information about an aggregation operation.

SESSCACHE


An option that controls whether Oracle OLAP uses the session cache to store variable data that has been aggregated on the fly.

VARCACHE


An option that specifies if and where variable data that has been aggregated on the fly should be stored. (The VARCACHE option is only one factor that can determine this decision.)


Allocation Options

A number of options effect allocation. These options are listed in Table A-6, "Allocation Options".

Table A-6 Allocation Options

Option Description

ALLOCERRLOGFORMAT


An option that determines the contents and the formatting of the error log that you specify with the ERRORLOG argument to the ALLOCATE command.

ALLOCERRLOGHEADER


An option that determines the column headings for the error log that you specify with the ERRORLOG argument to the ALLOCATE command.

A number of options effect how a model solves simultaneous blocks. These options are listed in Table A-7, "Model Options".

Table A-7 Model Options

Option Purpose

MODDAMP

MODERROR


Specifies the action to be taken when a model equation diverges or a block fails to converge. The possible values are STOP, CONTINUE, and DEBUG.

MODSIMULTYPE


The solution method to use. The possible values are AITKENS (for the Aitkens delta-squared method) and GAUSS (for the Gauss-Seidel method).

MODTOLERANCE


A value that is used in testing for convergence. It controls how closely the results must match between iterations for an equation to be considered to have converged.
