Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 0 Modification 1. * **************************************************************** * PROBLEM DESCRIPTION: SVRCONN connections unnecessarily * * access the SYSTEM.CHANNEL.SYNCQ queue * * in order to check the sequence number. * **************************************************************** * RECOMMENDATION: * **************************************************************** When a SVRCONN channel starts, function rrxReadChannelDef calls rrxReadResetRec to obtain the sequence number for the channel. It obtains the sequence number by doing an MQGET on the SYSTEM.CHANNEL.SYNCQ queue (which you can see from the SMF statistics). SVRCONN channels do not use sequence numbers, however, so this call is unnecessary.
Problem conclusion
rrxReadChannelDef no longer calls rrxReadResetRec if the channel being started is a SVRCONN. 010Y CSQXRCDF
