Title: RE: Puzzled: MQJE001, MQRC 2102 for non-mqm users

I found the following in the text for CSD 5 for V5.3 on AIX. It MIGHT help explain
why you got a 2102 and not an access error:

IY43097 - Occasionally a failure with return code 2102
             (MQRC_RESOURCE_PROBLEM) occurred when trying to connect
             aplications to WebSphere MQ V5.3. When a large number
             of applications attempted to perform a get operation
             with large buffer sizes, the shared memory set was
             extended, but with incorrect permissions. This meant
             that applications run under a user id which did not
             have mqm as its primary group could not connect to this
             extent, getting EACCESS from shmat. This was returned
             as a resource problem.

Peter,

When referring to the WMQ manuals, be sure that you visit
http://www-306.ibm.com/software/integration/mqfamily/support/readme/cli530_r
ead_2.html for the manual updates as there is a lot of corrected information
regarding SSL.

Thanks.. I see there is a redbook on Implementing MQ security from May
2003.. Is that the latest publication on MQ and SSL?

"I've been off the MQ board for six months.. Has implementing SSL gotten
any easier with MQ 5.3.5 ?"

From an MQ perspective, it is the same as when it first came out with
5.3.

That's right.. I have heard this before. I could use the incoming userid
and incoming machine name and perform a lookup in a table and get an
assigned userid that has the correct priviledges. And that's about
halfway to the better solution of SSL and certificates. Our organization
has not implemented application level SSL and certificates so a
homegrown solution may be our only current option.

I've been off the MQ board for six months.. Has implementing SSL gotten
any easier with MQ 5.3.5 ?

But the real user could be some loser that defines the ID "mqm" on their
machine, logs on with that ID, and then your QM has no choice but to let
him do whatever they want!

I'm sorry - I took the documentation to mean that for non-Java clients,
on Windows and UNIX, the userid in the MQCD is the currently logged on
user and that the environment variables are not referencved. So if I
could verify that it was not a Java client, then I could rely on the
userid to be the real user.
