Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: This APAR enables the ability to * * restrict shared outgoing TCP channels * * from being started on specified queue * * managers through a service parm. * **************************************************************** * RECOMMENDATION: * **************************************************************** All queue managers within a queue sharing group, with an active channel initiator may be eligible to have a outgoing shared channel started on it. The starting of a outgoing shared channel can either be fixed to only a single queue manager, or any eligible queue manager in the QSG. Any queue manager with connection to the QSG, DB2 and the appropriate communication subsystem, and spare capacity (not at max channels or max channels for the communication method) can be selected. However it may not be appropriate for some qmgrs in the QSG to be able to start outgoing channels while still having an active channel initiator. This APAR implements the ability to restrict the starting of outgoing shared channels using TCP to be started on specific qmgrs.
Problem conclusion
A new service parm has been introduced to allow a queue manager to be restricted from starting outgoing shared TCP channels. Please contact IBM support for further details on how to enable this. --------Knowledge Center Changes-------- A new page will be added knowledge center at location >WebSphere MQ >z/OS Messages and Codes >Distributed queuing messages (CSQX...) Title - CSQX117I: csect-name Outgoing shared channels are restricted from starting for TCP communication Contents- Explanation - A CHISERVP() service parm flag has been set which restricts the ability for this queue manager from being able to start an outgoing shared TCP channel. For more details on this flag contact IBM support. Severity - 0 System action - Processing continues. This queue manager will be unable to start outgoing shared TCP channels, and will not be selected during MQ workload balanced start of a shared channel. This restriction will persist until the flag is disabled and channel initiator is restarted. ---------------------------------------- A link to the new page will also be added to page at location >WebSphere MQ >z/OS Messages and Codes >Distributed queuing messages (CSQX...)
