Displaying PDS V2 data set information

Edit online

Use the QUERY DATASTORE command to display information about data sets known to the PDS V2 engine for a particular product.

Important: The content in this section was created for and applies to persistent data store V2 (PDS V2).

To display PDS V2 data set information, enter the following MODIFY command:

F stcname,KPQ QUERY DATASTORE APPL=application

where:

stcname is the started task name of the address space where the persistent data store is running.
application is the code of the component (for example, KC5 for OMEGAMON for CICS).

The command output is written to RKLVLOG. To review the output, locate messages KLVOP191 and KPQH043I.

For each data set, the total number of allocated bytes, the number of used bytes, and the status are displayed. For information about possible statuses of the PDS V2 data sets, see About PDS V2 data sets and statuses.

Tip: If there is a delay when writing records to RKLVLOG, you can use the following command to see the output immediately:

F stcname,FLUSH
RKLVLOG

Example

Command entered:

F TEMSSTC,KPQ QUERY DATASTORE APPL=KM5

Sample output:

KLVOP191    'KPQ QUERY DATASTORE APPL=KM5'
