Hi All,
We are upgraded Oracle 9.2 to 10G, After configuration we are facing some problem with QueueManager. i changed the qm.ini file, the changes are below:
XAResourceManager:
Name=myoracle
SwitchFile=jdbcora_10G
XAOpenString=Oracle_XA+Acc=P//+SesTm=35+LogDir=/RINd_apps/mhs/mqmhs/log
ThreadOfControl=PROCESS
After startin QM i am getting following error:
AMQ6254: The system could not dynamically load the shared library
'/var/mqm/exits64/jdbcora_10G', library '/var/mqm/exits/jdbcora_10G' has been
used instead.
EXPLANATION:
This message applies to UNIX systems. The shared library
'/var/mqm/exits64/jdbcora_10G' failed to load as it is probably a 64-bit
library, a 32-bit library is required. Note that MQ has sucessfully located and
loaded a 32-bit library named '/var/mqm/exits/jdbcora_10G'.
ACTION:
Supply the name of a 32-bit library or put the library (alternatively a
symbolic link can be used) in the appropriate place: 32-bit libraries in
/var/mqm/exits; 64-bit libraries in /var/mqm/exits64.
Its really great If anyone tell me what to do?
Thanks....Waiting for reply ~!!

The example also shows a fully qualified path name to the switch file, although the error message you posted implies that the switch file is in the exits directory (which to me seems an odd place to put it).

For example: SwitchFile=/usr/ora/jdbcora_10G
I just would not expect to see a switch-file placed in the exits directory.

Hi all.
I have done some changes to qm.ini :
#*******************************************************************#
#* Module Name: qm.ini *#
#* Type : WebSphere MQ queue manager configuration file *#
# Function : Define the configuration of a single queue manager *#
#* *#

Log:
LogPrimaryFiles=3
LogSecondaryFiles=2
LogFilePages=1024

XAOpenString=Oracle_XA+Acc=P//+SesTm=35+LogDir=/rind_apps/mhs/mqmhs/log
ThreadOfControl=PROCESS
[color=red]After the changes I stop and start the QM [/color]
I am getting following error:
-------------------------------------------------------------------------------
11/12/08 16:28:15 - Process(991364.1) User(rindmhs) Program(amqzxma0_nd)
AMQ6175: The system could not dynamically load the shared library
'/var/mqm/exits/jdbcora_10G'. The system returned error number '8' and error
message ' 0509-022 Cannot load module /var/mqm/exits/jdbcora_10G.
0509-103
The module has an invalid magic number.'. The queue manager will continue
without this module.
EXPLANATION:
This message applies to AIX systems. The shared library
'/var/mqm/exits/jdbcora_10G' 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.
----- amqxufnx.c : 1158 -------------------------------------------------------
11/12/08 16:28:15 - Process(991364.1) User(rindmhs) Program(amqzxma0_nd)
AMQ7622: WebSphere MQ could not load the XA switch load file for resource
manager 'myoracle'.
EXPLANATION:
An error has occurred loading XA switch file /var/mqm/exits/jdbcora_10G. If the
error occurred during startup then the queue manager will terminate. At all
other times the queue manager will continue without this resource manager
meaning that it will no longer be able to participate in global transactions.
The queue manager will also retry the load of the switch file at regular
intervals so that the resource manager will be able to participate again should
the load problem be resolved.
ACTION:
Look for a previous message outlining the reason for the load failure. Message
AMQ6175 is issued if the load failed because of a system error. If this is the
case then follow the guidance given in message AMQ6175 to resolve the problem.
In the absence of prior messages or FFST information related to this problem
check that the name of the switch load file is correct and that it is present
in a directory from which it can be dynamically loaded by the queue manager.
The easiest method of doing this is to define the switch load file as a
fully-qualified name. Note that if the queue manager is still running it will
need to be restarted in order that any changes made to its configuration data
can be picked up.
----- amqtrmca.c : 256 --------------------------------------------------------
What should i do now?

Invalid magic number might have something to do with the LIBPATH/ LD_LIBRARY_PATH. There is some literature about this in the upgrade manual from 5.3 to 6.0... Have fun

The switch load file needs to be loaded by app and queue manager processes.
Queue manager processes are 64-bit. Apps can be 64 or 32 bit.
You'll need a 32-bit version of the switch load file under /var/mqm/exits for 32-bit processes to load and a 64-bit version of the switch load file under /var/mqm/exits64 for 64-bit processes to load.
If this worked before for Oracle 9, I am wondering why it no longer works for Oracle 10.
It apparently(?) worked without a fully qualified path to the file, and this is what I would expect. If you put a fully qualified path in the qm.ini file then I would not expect the 32/64-bit heuristic I described above to work.
So, does it help to return to the non-qualified filename, and ensure the 2 versions of the jdbcora file are correctly located under /var/mqm/exits and /var/mqm/exits64 ? |

Do i need to change in qm.ini? what should i change in qm.ini?
How do i check for a version of jdbcora ?

Yes you will need to change qm.ini back to how it was in your post at 12:53 GMT / 17:53 EST.
You will need to ensure that as well as a 32-bit version of jdbcora_10G under /var/mqm/exits there is a 64-bit version of jdbcora_10G under /var/mqm/exits64.
That's my opinion, with a little bit of knowledge of how these things are supposed to work. I don't, however, have direct personal experience of setting it up myself.
If anyone else on the forum does have direct experience then hopefully they will speak up if I got any of these details wrong. |

Maybe the switchfile needs renewing, i.e. new version...only ever done this on WMQ V5.3 and can't remember what the Oracle version was, and I reiterate my previous statement - I would not expect to see it in the exit(s) directory.

That refers to a DB3 switchfile whereas kailashbawane is using Oracle - I don't know if there is a difference to how the switchfile(s) should be located.

And in that case the switch file was located in /directory/sub-directory/switchfile, where the directory was the user application root directory.
