Disabling RM from using the repository and stopping the RS address spaces

When all IMS systems have fallen back to not using the repository, you can disable RM from using the repository and stop the RS address spaces.

Procedure

  1. Remove the REPOSITORY section from the CSLRIxxx member of the IMS PROCLIB data set at each RM.
  2. Issue the UPDATE RM TYPE(REPO) REPOTYPE(IMSRSC) SET(REPO(N)) command to disable all RMs from using the repository.
  3. Issue the QUERY RM TYPE(REPO) SHOW(ALL) command to ensure that all RMs are not using the repository.
  4. Shut down all of the Repository Server (RS) address spaces by issuing the F reposervername,SHUTDOWN ALL command.
  5. Delete the IMSRSC repository and RS catalog repository data sets.
    To delete the data sets, use the z/OS® Access Method Services (IDCAMS) utility or a similar method.
  6. Delete the z/OS log stream if the RS audit log is not needed.
    You can use the IXCM2APU program to delete the log stream.
