Attempting to connect from the client to the SVRCONN channel with SCYEXIT-YES fails with reason code MQRC_CONNECTION_BROKEN(2009) or MQRC_Q_MGR_NOT_AVAILABLE(2059). Additionally, in writing a user exit, there was no pragma export allowing linkage to function mqscd_numActInst(), thereby preventing the exit from limiting the number of connections that would be allowed. When issuing ZMQSC ALTER CHL-channelname MAXMSGL or SOCKBUF on a SVRCONN channel, the file copy is updated. The memory copy is not modified, requiring an IPL to change this setting if the channel has been loaded into memory already. SOLUTION: TPF MQSeries channel security has been modified to function correctly. A pragma export directive has been added to allow linkage to function mqscd_numActInst(). ZMQSC ALTER CHL has been updated to change MAXMSGL and SOCKBUF on SVRCONN channels whether the channel has been loaded into memory or still resides on file. A new Security exit example has been added to user exit segment CUIT that limits the number of connections to a SVRCONN channel. DEPENDENCIES SEGMENTS TO BE ASSEMBLED OR COMPILED: None. SEGMENTS TO BE LINK EDITED: cmqs40.exe (Shipped in Tar File) cmqu40.exe (Shipped in Tar File) COREQS: None. MIGRATION CONSIDERATIONS: None.
