Problem summary
**************************************************************** USERS AFFECTED: Users setting very high value for MaxChannels in V6 and V7. Platforms affected: All Distributed (iSeries, all Unix and Windows) **************************************************************** PROBLEM SUMMARY: The queue manager calculates the Status table size based on the value set for the MaxChannels. When this value was very large, the queue manager tried to allocate large amount of memory for the channel status table. The attempt to allocate memory for a large channel status table failed, resulting in the AMQ9522 error.
Problem conclusion
Appropriate code changes have been made to restrict the MaxChannels to 65535 which is the maximum as per design. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v6.0 Platform Fix Pack 6.0.2.8 -------- -------------------- Windows U200309 AIX U825517 HP-UX (PA-RISC) U824678 HP-UX (Itanium) U825875 Solaris (SPARC) U825511 Solaris (x86-64) U825872 iSeries tbc_p600_0_2_8 Linux (x86) U825181 Linux (x86-64) U825874 Linux (zSeries) U825516 Linux (Power) U825182 Linux (s390x) U825873 v7.0 Platform Fix Pack 7.0.1.0 -------- -------------------- Windows U200306 AIX U823774 HP-UX (PA-RISC) U823665 HP-UX (Itanium) U823667 Solaris (SPARC) U823772 Solaris (x86-64) U824344 iSeries tbc_p700_0_1_0 Linux (x86) U823664 Linux (x86-64) U823773 Linux (zSeries) U823668 Linux (Power) U823666 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available, information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
