Installation for Existing Customers

If you are an existing CA OPS/MVS customer and are installing a new release of the product, then do one of the following:

• Review the migration issues listed in the chapter “Migration and Upgrade Consideration.” If there are any issues that pertain to your site, then you must address them before you can use the current OPSLOG and SYSCHK1 data sets that you created in a previous release of CA OPS/MVS with this release.
• Create new OPSLOG and SYSCHK1 data sets by following the steps for new users of CA OPS/MVS described above. Use the same allocation specifications for the new data sets that you specified in your current ones. Also, determine if the allocation size of your SYSCHK1 data set needs to be increased. For more information on how to increase it, see the appendix “DASD Calculation Chart.”

  If you have implemented the CA OPS/MVS global variable backup utilities, then you can invoke OPSSGVRS after starting this release of CA OPS/MVS to copy data into your new SYSCHK1 data set. If the CA OPS/MVS global variable backup utilities are not implemented, then you can use a system utility such as IDCAMS IMPORT and EXPORT to copy your existing SYSCHK1 data set to the newly allocated SYSCHK1 data set prior to starting this release of CA OPS/MVS.

Note: You cannot run two releases of CA OPS/MVS concurrently while allocating the same VSAM linear data sets. Additionally, you may be unable to convert from a new release of CA OPS/MVS to an older release.
