In a multiple DFSMShsm host environment, you must allocate a unique edit log data set for each host if the edit logs are cataloged in a shared catalog. Placing the edit log on a volume managed by another host can lead to degraded performance or lockout. Because the edit log data set cannot be shared among hosts, you should:

• Catalog the edit log data set.
• Allocate the edit log data set with a data set name of qualifier.EDITLOGn. Substitute the DFSMShsm authorized-user identification for qualifier and substitute a unique DFSMShsm host identifier for n. These substitutions make each data set name unique and identifiable with the host. Example: If the host identification is 1, the edit log data set name could be:
  • qualifier.EDITLOG1
