sibDDLGenerator command

Purpose

A messaging engine needs DBMS resources, such as database tables, which it can create when starting. If your installation has a policy that only a database administrator has the authority to create database tables, use the sibDDLGenerator command to enable your database administrator to create the DBMS resources that the messaging engine needs. The sibDDLGenerator command generates the DDL statements that your database administrator can save, and later process, to create the DBMS resources that are listed in Data store tables.

The command also generates DDL statements that grant the appropriate authorities to allow a messaging engine use these tables.

To access the IBM® i command line, use the STRQSH command to start a Qshell session. For more information, see Configuring Qshell to run WebSphere scripts using wsadmin scripting.

Optional parameters

Some parameters apply to a specific DBMS only, as indicated in the parameter list; for example: -database [Applies only to DB2® for z/OS]

-system

Identifies the type of DBMS on which the administrator will process the DDL statements. Valid values are:

• db2
• oracle
• sqlserver
• sybase
• informix
• derby

If you do not supply a -system parameter, the default value is derby.

-version

The version number of the DBMS identified by the -system parameter. The following table shows the default value that is used if you do not supply a -version parameter.

If you receive a CWSIS1595E or CWSIS1503E error when you run the tool, consult the notes after the table to determine whether an alternative -version parameter value can be used for your database version.

Table 1. Values for the -version parameter . The first column of the table lists the -system parameter values. The second column of the table lists the -platform parameter values. The third column of the table lists the default values of the -version parameters. The fourth column of the table lists the other accepted values of the -version parameters.

-system parameter value	-platform parameter value	Default value for the -version parameter	Other accepted -version parameter values
db2	zos	7.1	8.1, 9.1 (see Note 1)
db2	unix, windows	8.1	9.1 (see Note 1)
db2	iseries	5.2 (see Note 2)	5.3 (see Note 2)
oracle		8i	10g, 11g (see Note 3)
sqlserver		2000	2005
sybase		12.0	12.5, 15.0
informix		9.3	7.3, 9.4, 10.0, 11.0 (see Note 4)
derby		10.1

Notes:

1. The DDL generated for DB2 for UNIX or Windows by using -version parameter values 8.1, and 9.1 is identical. The DDL generated for DB2 for z/OS® by using -version parameter values 7.1, 8.1, and 9.1 is identical.
2. For IBM i, the DB2 database is part of the operating system, so the version number given is for the OS/400® version.
3. The DDL generated for Oracle by using -version parameter values 10g and 11g is identical.
4. The DDL generated for Informix® by using -version parameter values 10.0, and 11.0 is identical.

-platform

The operating system platform on which the DBMS runs. Valid values are:

• iseries
• unix
• windows
• zos

-schema

The name of the schema that contains all the objects used by the messaging engine. If you do not supply a -schema parameter, the default value is IBMWSSIB.

-user

The name of the user ID that is used to interact with the DBMS. If you do not supply a -user parameter, the default value is IBMUSER.

-create | -drop

Indicates whether the DDL statements create the DBMS resources or delete them. If you do not supply either parameter, the default value is -create.

-database [Applies only to DB2 for z/OS]

The name of the database that is allocated for the messaging engine tables. If you do not supply a -database parameter, the default value is SIBDB.

-createdbstmt true/false [Applies only to DB2 for z/OS]

Specifies whether the CREATE DATABASE DDL statement must be generated. The sibDDLGenerator command generates the CREATE DATABASE DDL statement by default. If you specify false as the value for the -createdbstmt parameter, then the CREATE DATABASE DDL statement will not be generated.

-tablespaceprefix [Applies only to DB2 for z/OS]

The table space prefix used to generate the table space name. The prefix can have a maximum of 5 characters. If you do not specify the -tablespaceprefix parameter, table spaces are created using the predefined table space names.

-storagegroup [Applies only to DB2 for z/OS]

The name of the storage group that is allocated for the messaging engine tables.

• If you supply both the -storagegroup and the -catalog parameters, the sibDDLGenerator command includes both values in the CREATE STOGROUP statement.
• If you supply only a -storagegroup parameter, the sibDDLGenerator command uses the storage group name in other statements but does not create a CREATE STOGROUP statement.
• If you supply only a -catalog parameter, the sibDDLGenerator command displays the usage statement and then terminates.
• If you omit both parameters, the sibDDLGenerator command uses the default value SIBSG for the storage group name in other statements but does not create a CREATE STOGROUP statement.

-catalog [Applies only to DB2 for z/OS]

The name of the high level qualifier for the storage group that is allocated for the messaging engine tables. For information about defaults, refer to the -storagegroup parameter.

-bufferpool [Applies only to DB2 for z/OS]

The name of the buffer pool that is allocated for the messaging engine tables. If you do not supply a -bufferpool parameter, the default value is BP1.

-statementend

Appends statement_end to each DDL statement. For example, you can use ; to append a semicolon to each DDL statement. By default, the sibDDLGenerator command appends nothing to each statement.

Tip: On UNIX platforms, escape the semicolon to prevent the shell from interpreting it.

-nolinebreaks

Places each statement on a single line, with no line breaks. By default, the sibDDLGenerator command breaks statements across lines to improve readability.

-noblanklines

Omits blank lines between each statement. By default, the sibDDLGenerator command inserts a blank line between each statement to improve readability.

-firstline

Generates first_line as the first line of output. For example, you can use first_line to identify the target database. By default, the sibDDLGenerator command does not generate a first line.

-lastline

Generates last_line as the last line of output. For example, you can use last_line to invoke a command that executes the commands in the script. By default, the sibDDLGenerator command does not generate a last line.

Examples

• sibDDLGenerator -system db2 -version 8.1 -platform zos

  Generates DDL statements for DB2 8.1, running on z/OS, with a default schema, user ID, database, storage group, and buffer pool.

• sibDDLGenerator -system db2 -version 8.1 -platform windows -statementend ;

  Generates DDL statements for DB2 8.1, running on Windows, with a default schema, user ID, and database. You can input the statements directly to the DB2 CLP, which requires that each statement is terminated with a semicolon.

• sibDDLGenerator -system oracle -version 8i -schema SIB -user fred

  Generates DDL statements for Oracle 8i.

• sibDDLGenerator -system oracle -schema SIB -user fred

  A concise version of the preceding example.

• sibDDLGenerator -system db2 -version 9.1 -platform zos -createdbstmt false

  Generates DDL statements for DB2 9.1, running on z/OS, with a default schema, user ID, database, storage group, table space, and buffer pool without the CREATE DATABASE statement.

• sibDDLGenerator -system db2 -version 9.1 -platform zos -tablespaceprefix SIBTS

  Generates DDL statements for DB2 9.1, running on z/OS, with a default schema, user ID, database, storage group, buffer pool, and table space name generated with the specified table space prefix.
