Hi,
I'm trying to configure a MQSeries Server to use SSL, with no success 
After a lot of tests, readings and searches through the Internet, I strongly suspect of some incompatibility between the GSKit and the system libraries. I'll write down some details, if someone has ever seen this kind of problems please let me know. I also want to know from the Linux users who have SSL working: what version/distribution of Linux do you use and/or recommend?
First of all, in the GSKit installation the RPM complains of an unsatisfied dependency: libstdc++.so.3. However, the file IS there (to be more specific, it's in the /usr/lib directory and it's a symlink to libstdc++.so.5).
It only was possible to install the program using RPM --NODEPS
Then I procceded with the channel configuration. A common Sender channel, with the "extra" parameter SSLCIPH(TRIPLE_DES_SHA_US)
When starting the channel, the qm generates the following log message:

The system could not dynamically load the library
/opt/mqm/lib/amqccgsk_r. The error message was
/usr/local/ibm/gsk6/lib/libgsk6cms.so: undefined symbol: _ZNSt13_Format_cacheIcEC1Ev. The queue manager will continue without this module. |
A very strange error, a search on Google returned nothing of interest (no ocurrence related to MQ).
Next, I tried using SSL in another Server, with Red Hat 9 (by the way, the other one was a Suse9). I had the same error.
Linking the libstdc++.so.3 to an older version (libstdc++.so.2.9, kept by Linux for compatibility) causes the following channel error:

undefined symbol: __gxx_personality_v0. The queue manager will continue without
this module. |
Which toke me to a "conclusion": Changing the version of the library, the "undefined symbol" changes... does it mean that it must have a specific version? I tried to get the lib separately but it's not available anywhere.
MQSeries is version 5.3 with FixPack9
Thanks,
Rodrigo |
