F.1 Choosing Data Set Name Qualifiers

The gateway installation setup and initialization process creates the first of several z/OS data sets.  Later in the installation, you can specify the high-level and second-level data set name qualifiers that are used for subsequently created data sets.  Refer to the Oracle Database Installation Guide for IBM z/OS (OS/390) for a list the data sets and their default space allocations.

Oracle recommends that you use the same qualifiers for all of the installation-related data sets.  At this time, you need to choose and use the qualifiers that were selected during installation setup and initialization.

While choosing qualifiers, remember the following requirements:

• You must choose unique qualifiers.

  Using different qualifiers ensures that the products in the product set are maintained in separate libraries as required.

  Attention:

  1. Do not use the same qualifiers that you have used for any other Oracle for z/OS product set that you have previously installed. If you do, then the installation procedures will delete and reallocate your current Oracle libraries.

  2. Do not concatenate these libraries with any existing libraries that you are running for previously installed product sets.

• In most z/OS systems, some preparation is required before creating data sets with a new high-level data set name qualifier.

  If you intend to use a new high-level qualifier for your Oracle data sets, then you must define an ALIAS before running the job that loads the installation JCL. When in doubt, ask your z/OS systems programmer for assistance.
