Upgrading XA configurations
When you upgrade from Version 7 Release 1 or earlier, if you have a Gateway daemon configuration using XA support, you must change the configuration settings.
Analyze your existing configuration to determine the upgrade steps required
- Determine whether or not you are using XA support by checking
the xasupport parameter in the Gateway daemon configuration
file.
- If xasupport=off, or if the configuration file does not contain the xasupport parameter, no upgrade steps are needed and the CICS® Transaction Gateway will work as it did before the upgrade.
- If xasupport=on, you are using XA and you must follow the upgrade steps.
- Analyze the configuration to determine if the Gateway daemon is
part of a Gateway group by looking for the CTG_RRMNAME and CTG_MASTER_RRMNAME environment
variables in the STDENV DD card of the JCL for the CTGBATCH job step.
Older configurations might have set the same environment variables
in a ctgenvvar script that is located on the HFS. You
can also check the Gateway daemon log
for message CTG9214I which indicates that the Gateway daemon is
part of a Gateway group.
- The Gateway is not configured to be part of a Gateway group if CTG_RRMNAME is specified and CTG_MASTER_RRMNAME is not specified.
- The Gateway is configured to part of a Gateway group if both CTG_RRMNAME and CTG_MASTER_RRMNAME are specified. All Gateways that share the same CTG_MASTER_RRMNAME are in the same Gateway group.
