Hi,
We are running into problems trying to read logical partitioned messages on the LINUX queues.
One of our maps (Reque) puts data on to the queue. Reque map splits the data if the data size is bigger than 3.8 MG. We use the PKT command of Mercator (PKT 3800) for splitting. When we run a file of 6 MG it splits into two files and we can see the logical split file (based on MID) on the queue. When we try to pull the messages from the queue using CMSG option we are getting an Mercator failure: Source Not Available. On the mq trace we are getting return code 2010 . Set up is working fine for the AIX queues but does not work for the queues set up on the LINUX box.
We are using client channel table to connect to the MQ. If we pull the msg as separate it is working fine!! I increased Serverconnection and Client connection channles msg length to 100mb.
The same map is working fine on other box where mercator and mq running on the same box!!
Pls throw some light on this!!
Thanks in advance,
Chandra. |

Did you stop and restart the SVRCONN channel after this so your changes took? (CLNTCONN channels do not support a Maximum message length parameter by the way.)
Did you up the max message size parameter (MaxMsgLength) at the Queue Manager level?

Hi Peter,
- in the MQSC commandes manual - page 103 - they that on most of the platforms you can define messages which length may be greater tha 4Mbytes:
<---------------
MAXMSGL(integer)
Specifies the maximum message length that can be transmitted on the
channel. This is compared with the value for the partner and the actual
maximum used is the lower of the two values.
The value zero means the maximum message length for the queue
manager.
On AIX, Compaq OpenVMS, HP-UX, Linux, OS/2 Warp, OS/400, Solaris,
and Windows, specify a value in the range zero through to the maximum
message length for the queue manager.
See the MAXMSGL parameter of the ALTER QMGR command for more
information.
On z/OS, specify a value in the range zero through 100 MB.
On other platforms, specify a value in the range zero through 4 194 304
bytes (4 MB).
----------->
Cheers,
Jack |
