Error description
The channel status output for a running MQ SVRCONN channel returns with an empty MCAUSER property. This occurs when the channel negotiates a SHARECNV (conversation sharing) value of zero (0).
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All Users of IBM MQ for z/OS Version 9 * * Release 1 Modification 0 * **************************************************************** * PROBLEM DESCRIPTION: Channels which have a negotiated * * SHARECNV value of zero will have a * * blank MCAUSER attribute when displayed * * via the runmqsc DISPLAY CHSTATUS * * command. (Or by viewing Channel Status * * in MQ Explorer). * **************************************************************** On channel startup, the MCAUSER was not stored correctly by the rriSetMCAUser routine. As a result, when using the DISPLAY CHSTATUS command for SVRCONN channels with a SHARECNV value of 0, the MCAUSER was displayed as blank, instead of its actual value.
Problem conclusion
Code had been added to the rriSetMCAUser routine, to store the MCAUSER from pCDMCAUserId in the case of non-multiplexed channels.
