Overriding Default DB2 UDB Storage Parameters

Siebel Systems provides the option of overriding default storage parameters, such as the tablespaces you created using the instructions under Creating DB2 UDB Tablespaces, in which specific tables or indexes are created. To override these defaults, edit the ddl.ctl file located in the dbsrvr\DB2UDB directory.

NOTE:  The ddl.ctl file should be modified only by a qualified DBA.

For each Siebel table, you can specify a tablespace by using the Table Space parameter. In the following example, the tablespace for the table S_APP_VIEW is set to DATA1.

As provided by Siebel Systems, the .ctl file does not set storage parameters for the objects it creates, so they default to the parameters of the tablespaces in which they are created. However, the Table Space parameter will works under the following conditions:

• The table does not yet exist (for example, when you are performing a new database installation).
• The table needs to be rebuilt, in other words, there are schema changes made to the table such that an ALTER TABLE command is not sufficient to implement the schema changes, requiring that the Siebel application drop and re-create the table.

As shown in the following example, you can use the Table Space parameter to set storage parameters for specific tables.

[Object 219]
Type = Table
Name = S_APP_VIEW
Column 1 = ROW_ID VARCHAR(15) NOTNULL
Column 2 = CREATED TIMESTAMP NOTNULL DEFAULT %NOW%
Column 3 = CREATED_BY VARCHAR(15) NOTNULL
Column 4 = LAST UPD TIMESTAMP NOTNULL DEFAULT %NOW%
Column 5 = LAST_UPD_BY VARCHAR(15) NOTNULL
Column 6 = DCKING_NUM NUMERIC(22,7) DEFAULT 0
Column 7 = MODIFICATION_NUM NUMERIC(10,0) NOTNULL DEFAULT 0
Column 8 = CONFLICT_ID VARCHAR(15) NOTNULL DEFAULT '0'
Column 9 = NAME VARCHAR(50) NOTNULL
Column 10 = DESC_TEXT VARCHAR(255)
Column 11 = LOCAL_ACCESS_FLG CHAR(1)
Table Space = data1

The following example illustrates how to override the defaults for specific tables and indexes.
