Information Store database properties

The Information Store database properties files specify the names and details of database objects that are used in the Information Store. There are separate files for IBM® Db2®, Microsoft™ SQL Server, and PostgreSQL.

The InfoStoreNamesDb2.properties, InfoStoreNamesSQLServer.properties, and InfoStoreNamesPostgres.properties files are in the toolkit\configuration\fragments\opal-services-is\WEB-INF\classes directory.

The settings in these files control the following database objects:

The names of the database schemas
The name of the deletion by rule role
The collation sequence
For Db2, the page size
For Db2, the names of the buffer pools
For SQL Server, the logical names and locations of the filegroup files

Note: If you change the values for any of the settings after the Information Store is created, you must either manually change the names of the database objects in your database management system or re-create the database.

Settings for SQL Server

The InfoStoreNamesSQLServer.properties file contains the following settings that are specific to deployments that use Microsoft SQL Server to host the Information Store database.

For the Filename settings, you must specify a file name or absolute path. If you specify a file name, it is located relative to the value that is specified in the environment.properties file for the db.database.location.dir property. If you specify a file path, it is considered an absolute path.

ISSchema

The Information Store schema contains internal configuration information about the Information Store database.

By default, the value is IS_Core

PrimaryName

The SQL Server database primary data file contains the startup and configuration information for the Information Store database. The logical name of the primary data file.

PrimaryFilename

The filename or absolute path for the primary data file.

By default, the value is IStore-p1.mdf

UserTableName

The user table filegroup contains all the tables and data for the Information Store database. The logical name of the user table in the user table filegroup.

By default, the value is User_Table_Data

UserTableFilename

IndexName

The index filegroup contains the indexes for the Information Store database. The logical name of the index file.

By default, the value is IStore_Indexes

IndexFilename

The filename or absolute path for the index file.

By default, the value is IStore-i1.ndf

LobName

The LOB filegroup contains the tables that Store LOB data. The logical name of the lob file.

By default, the value is IStore_Lobs

LobFilename

The filename or absolute path for the index file.

By default, the value is IStore-b1.ndf

MemoryOptimizedName

The memory-optimized filegroup holds one or more containers that contain data files, delta files, or both for memory-optimized tables. The logical name of the memory-optimized file.

By default, the value is IStore_Memory_Optimized

MemoryOptimizedFilename

The filename or absolute path for the memory-optimized file.

By default, the value is IStore-mo1.ndf

Settings for PostgreSQL

The InfoStoreNamesPostgres.properties file contains the following settings that are specific to deployments that use PostgreSQL to host the Information Store database.

ISSchema

The Information Store schema contains internal configuration information about the Information Store database.

By default, the value is IS_Core

Collation_Deterministic, Collation_Locale

The (ICU) collation used for the Information Store in PostgreSQL. You can only change these settings before you create the Information Store database.

If Collation_Deterministic is true, all operators are case- and accent-sensitive.

If Collation_Deterministic is false:

"exact" operators follow the rules of the Collation_Locale
the "like" operator is governed by Collation_Sensitivity

By default, the values are false and en-US-u-ks-level1 (US English, case- and accent-insensitive).

Collation_Sensitivity

The case- and accent-sensitivity of the "like" operator when Collation_Deterministic is false. The value must be one of CIAI, CIAS, CSAI, or CSAS.

By default, the value is CIAI (case- and accent-insensitive).

CollateClause

The collation used throughout columns in the Information Store in PostgreSQL. This setting is required for correct sorting of text-based columns when using non-deterministic collation. If you plan to use deterministic collation (such as case-sensitive collation), set this property to be empty.

By default, the value is COLLATE public.istore_collation.

DatabaseTablespace

The default tablespace for the Information Store database. This tablespace, like all the others, must be present in the PostgreSQL cluster before the database is created.
