Customization Options

The CA Disk product provides the DASD administrator with a great deal of flexibility. In the pages that follow, several of the more commonly used customization options are discussed.

Whenever a CA Disk customization option directly changes the operating system, it is highly advisable to apply the change as a usermod using SMP/E. At the same time, any change you make to CA Disk itself should be considered as a usermod. You should also make these changes using SMP/E.

Each customization step discussed includes the proper JCL and instructions to install with SMP/E. After you have installed CA Disk with SMP/E, make sure that you have run the ACCEPT step prior to installing any customizing options. This allows for the easy removal of these options, if problems should occur.

Observe the following:

• Several SMP/E format usermods have sample JCL, which should NOT be modified. This sample JCL is always proceeded by a ++JCLIN control card. This sample JCL is used by SMP/E to indirectly determine the libraries to be updated. The sample JCL does not directly identify these libraries. Modification of this sample JCL can cause unpredictable results during installation of the usermod.
• Always verify the target and distribution zones into which you are installing each usermod. Usermods which modify your operating system--for example, the CA Disk SVC, VSAM date stamp and so on--should be installed into the same zones as your operating system. Usermods that modify CA Disk, such as auto restore zaps, and so on, should be installed into the same zones as CA Disk. Improper selection of target and distribution zones during the installation of user modifications can cause unpredictable results during installation.

As part of your planning for installing one or more customizing options, verify that the JCL provided conforms to your installation's JCL procedures. The Assembler JCL provided uses step names of C and L. Your Assembler procedure can use ASM and LKED. SMP/E JCL uses the DDNAME SMPCNTL.

The following customizing options are discussed in this section:

• The CA Disk SVC and applicable zap
• The CA Disk VSAM date stamp module
• The auto-restore function
• The CA Disk tape management facility

• Defining ISPF user options
