Hi David, Looking at your error messages, I don't believe that you have run out of space.
It looks to me like you have run out of kernel resources, either file descriptors or semaphores. You need to look in the manual for information about setting up your OS to support MQ. Also remember that the manual specifies the requirements for 1 queue manager, so you will probably need to increase some of these values when running multiple queue managers. The trick is to look at which limits are per process (IBM recommendations are fine) and which limits are system wide (may need to be increased when multiple queue managers are present). The relevent section for Linux is in the Quick Reference... http://publib.boulder.ibm.com/infocenter/wmqv6/v6r0/topic/com.ibm.mq.amq1ac.doc/lq10410_.htm Regards, Neil Casey Lead Technical Specialist, Middleware MQ Support Technology Operations National Australia Bank Level 1, 122 Lewis Rd (Mon Fri) Tel: +61 (0) 3 9886 2375 | Fax: +61 (0) 3 9886 2700 | Mob: +61 (0) 408 356 208 Pier 4, Level 8, 800 Bourke St (Tue Wed Thu) Tel: +61 (0) 3 8634 2205 | Fax: +61 (0) 3 8634 3788 | Mob: +61 (0) 408 356 208 Email: [EMAIL PROTECTED] "Awerbuch, David" <[EMAIL PROTECTED]> Sent by: MQSeries List <MQSERIES@LISTSERV.MEDUNIWIEN.AC.AT> 15/03/2007 04:53 Please respond to MQSeries List <MQSERIES@LISTSERV.MEDUNIWIEN.AC.AT> To MQSERIES@LISTSERV.MEDUNIWIEN.AC.AT cc Subject Calculating disk space requirements for queue manager I have 2 Linux systems running WMQ 6.0.1.0, with 1 queue manager on each. I am adding 4 additional queue managers to each system. On system #1, I was able to create the queue managers and all the required objects, The user today reported he could put a message (Java client appl), and when he disconnected the appl could not reconnect (mqrc=2009). I found the queue manager had terminated, generating an FDC in component GetSemSet (lib/cs/unix/linux_2/amqxlpix.c) in amqzlaa0 with error AMQ6119: An internal WebSphere MQ error has occurred ('28 - No space left on device' from semget.). Further down in the FD file is a reference to file /var/mqm/qmgrs/QM_JVAPPDEV10_2/esem/8, so I guess the /var filesystem (which is 2GB big with less than 800MB available) is the culprit. On system #2, since there are already 9 queue managers, I got as far as in the middle of creating my #1 of 4 when I hit the same error message, logged in /var/mqm/errors/AMQERR01.LOG. My question is: what calculations need to / should be done to determine the required disk space for a queue manager, given the numbers of objects of specific types, number of local application connections, remote connections, cluster connections, etc. I?ve never put much thought into mass-storage requirements other than #msgs X maxmsgsize to ensure messages can be stored to disk, and for log files (another question for another day ? how to calculate expected log file usage). Any assistance appreciated. I the meantime I have asked for 10GB slices off the SAN, but I would like to make an accurate and correct request for space.
