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.
You can also check the Gateway daemon log
for message CTG6737I which indicates that XA support
is enabled.
- 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.
