Extracting the Storage Control File


After you have created the staging database but before you begin to generate the upgrade files, you must extract the storage control file from the staging database and merge it with a Siebel 8.0 template. You do this using the Database Configuration Wizard Extract from Catalog and Merge with Template option.

To extract the storage control file

  1. Run the Database Configuration Wizard.

    For information on running the Database Configuration Wizard, see About Running the Database Configuration Wizard Under Windows or About Running the Database Configuration Wizard Under UNIX.

  2. Enter the information in Table 9 when prompted by the Database Configuration Wizard. Collect this information and verify it before running the utility.
  3. Save the information you have entered and launch the Upgrade Wizard as described in Running the Database Configuration Wizard to Perform Upgrade Tasks.

    The database catalog is read and your prior custom database layout is merged with one of the 8.0 Siebel database layout templates (located in the DBSRVR_ROOT\db2390 directory). New objects take a layout from one of the layout templates.

    NOTE:  If you choose a Siebel storage control file template that includes partitioning, and the existing database schema does not include partitioning, by default, the existing database objects are not partitioned in the storage control file generated (that is, the database catalog overrides the templates) unless you specify the table names in the override input file (override.inp).

    By default, new tables are created with one table in each database to prevent concurrency and locking errors.

Once the merged storage control file is created, you must verify it against the staging database. See Validating the Extracted Storage Control File for information on this task.

Information Required For the Database Configuration Wizard Extract Option

Table 9 lists the information you must enter to run the Database Configuration Wizard Extract and Merge option.

Table 9. Information Required for the Database Configuration Wizard — Extract and Merge Option
Field Name or Menu
Required Information

Siebel Gateway Name Server Address

Enterprise Server name

The Siebel Gateway Name Server machine name and the Enterprise Server name.

Siebel Server Directory

The absolute path of the directory where the Siebel Server is installed, for example, C:\sba80\siebsrvr (Windows) or siebel/siebsrvr (UNIX). For UNIX, do not enter the string $SIEBEL_ROOT.

Siebel Database Server Directory

The absolute path of the directory where the Siebel Database Configuration Utilities are installed—for example C:\sba80\dbsrvr (Windows) or siebel/dbsrvr (UNIX).

RDBMS Platform

Choose IBM DB2 for z/OS.

Siebel Database Operation

Choose Run Database Utilities.

Database Utilities Options

Choose Configure Database

Database Configuration Options

Choose Extract Storage File to extract a storage control file.

Extract Options

Choose the Extract from Catalog and Merge with Template option.

This option preserves your existing layout. This option merges storage layout information from the database you specify with information that you already entered into a storage control file, only taking objects from the template that do not already exist in the catalog.

NOTE:  The first time that you run an upgrade, you must use the Extract from Catalog and Merge with Template option, thereby preserving your existing layout.

ODBC Data Source Name

Verify the ODBC name for connecting to the staging Siebel database.

Windows: To find the name of your ODBC data source, navigate to Start > Settings > Control Panel > Administrative Tools > Data Sources (ODBC). Click the System DNS tab to find the name of your ODBC data source.

UNIX: To find the name of your ODBC data source, type: vi $ODBCINI.

Database User Name

Enter the user name and password for the Siebel administrator of the staging database.

NOTE:  The staging database user name (user ID) needs to have authorization to set CURRENT SQLID.

Siebel Schema Qualifier

Enter the eight-character identifier that designates the Siebel schema for your staging database. This is also an authorization ID. The schema qualifier must start with a letter, cannot contain special characters, and must be entered in uppercase.

Database Encoding Scheme

Specify whether your database is UNICODE or Non-UNICODE.

When you are upgrading to Siebel 8.0, choose Non-UNICODE.

Code Page Encoding Scheme

Indicate whether your DB2 subsystem is ASCII or EBCDIC.

Environment Type

Indicate whether your database environment is production or development.

Storage Control File Layout

Choose Siebel Schema without Partitioning if you want all tables only in segmented table spaces.

Choose Siebel Schema with Partitioning if you want a layout that includes a set of tables that is recommended for partitioning. The remaining nonpartitioned tables are in segmented table spaces.

Default Tablespace

Enter the name of the default table space.

Storage Group for Tablespaces

Storage Group for Indexes

Indicate the values for the following parameters:

Storage Group for Tablespaces. Enter the name of the table storage group.

Storage Group for Indexes. Enter the name of the index storage group.

4KB Buffer Pool Name

8KB Buffer Pool Name

Indicate the values for the following parameters:

4KB Buffer Pool Name. Enter the 4-KB buffer pool name for your table spaces or accept the default name, BP1. This buffer pool must already be activated and have access to it granted by the DBA.

8 KB Buffer Pool Name. Enter the 8-KB buffer pool name for your table spaces or accept the default name, BP8K1. This buffer pool must already be activated and have access to it granted by the DBA.

16KB Buffer Pool Name

32KB Buffer Pool Name

Indicate the values for the following parameters:

16KB Buffer Pool Name. Enter the 16-KB buffer pool name for your table spaces or accept the default name, BP16K1. This buffer pool must already be activated and have access to it granted by the DBA.

32KB Buffer Pool Name. Enter the 32-KB buffer pool name for your table spaces or accept the default name, BP32K1. This buffer pool must already be activated and have access to it granted by the DBA.

Index Buffer Pool Name

Database Name Prefix

Indicate the values for the following parameters:

Index Buffer Pool Name. Enter the buffer pool name for indexes or accept the default name, BP2. This buffer pool must already be activated and have access to it granted by the DBA.

Database Name Prefix. Enter the prefix for your target database name. The default prefix is SIDB.

This prefix consists of up to four of the first characters in the names of your logical Siebel Databases. This prefix must start with a letter and cannot contain any special characters. All database names end in numbers.

Storage Control File

Enter the directory path and name for the storage control file created by this process. You must accept the default value displayed in the Storage Control File field; this varies depending on the type of upgrade you are performing:

  • Development environment upgrade: storage_upg_dev.ctl
  • Production environment upgrade: storage_upg_prod.ctl.

Log Output Directory

Accept the default or enter the directory name. If the directory does not exist, it will be created. Do not use special characters such as spaces, slashes, or symbols in the name of the log output.
