TCPaccess apar MA06505
If the TCP/IP product that Mainframe Connector will be communicating through is Computer Associates product, TCPaccess (newly renamed to NETWORKIT), you should install TCPaccess apar MA06505. Without this fix, every new socket connection will leave behind a x’828’ byte storage block in the Mainframe Connector address space. If enough socket connections are created, this can lead to abend878 conditions in the Mainframe Connector address space.
