Upgrading a Gateway group with XA support

  1. Refresh the CTGRRMS services, follow the steps in Refreshing CTGRRMS services.
  2. Determine all Gateway instances that use the same CTG_MASTER_RRMNAME value. All Gateways with the same value are in the same Gateway group.
  3. Remove the CTG_RRMNAME and CTG_MASTER_RRMNAME parameters from the STDENV file for each Gateway within the group.
  4. Specify the same APPLID qualifier for each Gateway daemon which is to be a member of a Gateway in the group. It must be unique within the sysplex for this Gateway group. A Gateway daemon group is identified by the APPLIDQUALIFIER parameter. See Configuring identification using APPLID for a general explanation of APPLID and APPLIDQUALIFIER. See EXCI server connections for details on setting APPLID and APPLIDQUALIFIER when XA support is enabled.
  5. You must permit access for the Gateway daemon USERID to one of the following RACF® facilities when XA support is enabled:
    • ALTER access to the MVSADMIN.RRS.COMMANDS.** facility.
    • ALTER access to the MVSADMIN.RRS.COMMANDS.gname.sysname facility.
gname
is the logging group name and corresponds to the logging group in the RRS administrative panels in ISPF. Set gname to the value for the sysplex where the Gateway is running.
sysname
is the system name. Set sysname to the value for the LPAR where the Gateway is running

If you give ALTER access to MVSADMIN.RRS.COMMANDS.** the Gateway daemon is permitted to perform recovery operations for transactions associated with any system name or logging group. This option requires less administration but does not provide granularity of control.

If you give ALTER access to MVSADMIN.RRS.COMMANDS.gname.sysname the Gateway daemon is permitted to perform recovery operations for transactions associated with the specified system name or logging group. This option allows for greater granularity of control but requires a greater amount of administration.
