There are three primary options in the ISPF Customization Panels as shown in the following list:
View CA Vtape Customization Log. This option allows the viewing of the CA Vtape customization options log. The customization log is rewritten every time a customization session is completed. The customization log documents the parameter values entered during the last customization session and statistics concerning the JCL generated.
Copy the CA Vtape customization log to a protected data set to maintain a historical reference of past customization sessions.
Regenerate JCL for an existing CA Vtape complex. This option regenerates the SVTJCL library JCL members and the SUTPARMS configuration member. You cannot change the previously entered DSN Prefix and Virtual Volume Size. Changing these values would make the JCL and SUTPARMS members generated incompatible with an existing CA Vtape Complex. These values can only be changed with the Define option.
Invoke this option to regenerate the installation JCL to replace lost JCL and SUTPARMS members.
Define a new CA Vtape complex. This option generates the SVTJCL library JCL members and the SUTPARMS configuration member used to define and initialize a CA Vtape Complex. The JCL includes delete statements for an existing CA Vtape Complex. Changing the CA Vtape DSN Prefix and Virtual Volume size are permitted.
Invoke this option when defining a new CA Vtape Complex.
Important! Selecting this option and submitting the generated JCL members can cause data loss if elements of an existing CA Vtape complex are deleted and access to existing Virtual Volumes is lost. Select this option only to define and initialize a new CA Vtape complex using a new DSN prefix.
