Running TLS client applications with multiple installations of GSKit 8.0 on AIX
TLS client applications on AIX® might
experience MQRC_CHANNEL_CONFIG_ERROR and error AMQ6175 when
running on AIX systems with multiple IBM® Global Security Kit (GSKit) version 8.0
installations.
When running client applications on an AIX system
with multiple GSKit 8.0 installations, the client connect calls can return
MQRC_CHANNEL_CONFIG_ERROR when using TLS. The /var/mqm/errors logs
record error AMQ6175 and AMQ9220 for the failing client
application, for example:

AMQ6175: The system could not dynamically load the shared library
'/usr/mqm/gskit8/lib64/libgsk8ssl_64.so'. The system returned
error number '8' and error message 'Symbol resolution failed
for /usr/mqm/gskit8/lib64/libgsk8ssl_64.so because:

EXPLANATION:
This message applies to AIX systems. The shared library
'/usr/mqm/gskit8/lib64/libgsk8ssl_64.so' failed
to load correctly due to a problem with the library.
ACTION:
Check the file access permissions and that the file has not been corrupted.

AMQ9220: The GSKit communications program could not be loaded.
EXPLANATION:
The attempt to load the GSKit library or procedure
'/usr/mqm/gskit8/lib64/libgsk8ssl_64.so' failed with error code
536895861.
ACTION:
Either the library must be installed on the system or the environment changed
to allow the program to locate it.

LIBPATH or
LD_LIBRARY_PATH environment variable has caused the IBM MQ client to load a mixed set of libraries from two different
GSKit 8.0 installations. Executing an IBM MQ client
application in a Db2® environment can cause this
error. To avoid this error, include the IBM MQ library directories at the front of the library path so that the IBM MQ libraries take precedence. This can be achieved using the setmqenv command with the -k parameter, for example:
. /usr/mqm/bin/setmqenv -s -k
