Managing the XBM repository

The XBM repository stores all management sets and configurations that you define. The XBM repository also stores the XBM options that you have specified. When you save an XBM file or change the XBM options, XBM writes the changes to the repository. When you install XBM, you allocate the data sets for the XBM repository.

The repository consists of at least one internally managed VSAM keyed-sequenced data set (KSDS). You can allocate up to nine repository data sets per 

XBM

 subsystem, with the additional data sets serving only as backup copies. BMC recommends that you allocate at least two copies of the 

XBM

 repository and place them on different devices.

No matter how many data sets you allocate for the XBM repository, XBM keeps all data sets current. Maintaining multiple copies of the XBM repository on different devices helps ensure that you will not lose data that is stored in the XBM repository.

Important

Before upgrading to a new version or release of , you should always make a backup copy of your existing repository. Repository formats are not backward compatible. If you do not back up your repository before you upgrade, you can revert to an earlier version, but you might have to re-create your repository (including management sets, configurations, and any  options that you specified).
