Use the PURGE keyword to purge all entries from the specified INMSG or OUTMSG workspace data set for the node specified on the NODE keyword. You must make the connection with the node dormant before you can purge a workspace data set for it. When you purge a workspace data set, requests that were saved in it are lost, and database inconsistencies might result. The PURGE keyword can be used for error recovery when there is erroneous data in a workspace data set causing RACF® to fail.
