Making backed up data available

After data has been backed up to DASD or to tape, it can be made available to those products that use it.

About this task

Important: The content in this section was created for and applies to the original persistent data store, referred to as PDS V1. A new PDS version (referred to as PDS V2) now exists. PDS V1 will eventually be deprecated.
When the automatic maintenance facility backs up a data set in the persistent data store, it performs the following actions:
  • Disconnects the data set from the monitoring server
  • Copies the data set to tape or DASD in a format readable by the monitoring server
  • Deletes and reallocates the data set
  • Reconnects the empty data set to the monitoring server
To view backed up data from the product, you must ensure that the data set is stored on an accessible DASD volume and reconnect the data set to the monitoring server. The following steps outline the procedure for reconnecting a backed up data set.
  • Understand the naming convention for backed up data sets.
  • Determine whether data collection is taking place in the Tivoli Enterprise Monitoring Server or agent address space.
  • Find the data set you want to reconnect.
  • Connect the data set to the collector address space.
  • Disconnect the data set from the collector address space.
