Displaying available historical data

You will receive an error message if you request a view with data that is outside the time or date range stored on any of the historical data sets. This section shows how to use the DSLIST view to determine whether your historical data sets hold the data that you want to view.

1. Enter main from your current VistaPoint view.
   You are returned to the MAIN view of the product whose view you were displaying before the main command was issued.
2. Change to a target context if you are in SSI mode.
   You must be in a target context to view historical data sets.

3. Type view dslist to display the DSLIST view.

   The following figure shows the DSLIST view with a list of current historical data sets. In this example, the window information line shows that VistaPoint is the active product and CICSP01 was the current context when the DSLIST command was issued:

     HISTDS03 08NOV2000  08:00 08NOv2000  14:30 Yes Active ******** BBM20.LGS1

   In this, four historical data sets are available. They hold data collected from November 6, 2000 to the current date of November 8, 2000. The STATUS field shows that HISTDS03 is the active data set, currently storing data at the end of every recording interval. The most current interval was recorded at 14:30 on November 8th.

   Tip

   You can manage your historical data sets with actions available from the DSLIST view. DSLIST provides two types of actions:

   • COMMAND line actions

   ADD                          Adds a new historical data set.

   SAVE                        Saves current historical data set configuration to the PARMFILE data set.

   • Line actions

   D (DEALLOCATE)    Deallocates an historical data set.

   F (FORCE)               Selects the next data set for recording.

   O (ORDER)              Toggles a data set's recording eligibility to Yes or No.

   Q (QUIESCE)           Restricts read/write access to a data set.

   R (EMPTY)               Empties an historical data set.

   U (UNQUIESCE)      Reinstates read/write access to an historical data set.

   If you do not see the date and/or time that you want in the historical data sets shown with DSLIST, one of the following conditions may have occurred:

   • Data has been archived to tape.
   • Data set is not currently allocated to your PAS.
   • Data has been purged from a listed data set.

   Contact your product administrator, who should be able to give you an answer regarding the location of the historical data you need. If you are the administrator, see BMC AMI Ops Infrastructure for information about the default operation of BBI-3 historical data sets.
