Overriding Oracle Default Storage Parameters

Siebel Systems provides the option of overriding the default storage parameters, such as the tablespaces in which specific tables or indexes are created. To override these parameters, appropriately edit the ddl.ctl file located in the dbsrvr/oracle directory.

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

For each Siebel object (table or index), 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 the Siebel application, the .ctl file does not set storage parameters for the objects it creates, so that they default to the parameters of the tablespaces in which they are created. However, the Table Space parameter only 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 recreate the table.

The following example illustrates the use of the Table Space parameter to set storage values 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

If you use locally managed tablespaces and want to change the storage parameters, see your Oracle technical documentation.
