Improved Memory Management for Listeners on z/OS

Improved Memory Management for Listeners on z/OS

PowerExchange introduces improved messaging and control of the PowerExchange Listener response to memory issues on z/OS.
When the PowerExchange Listener on z/OS starts, new messages display the available memory in the JCL control region and whether the size of the control region is adequate for the workload. Additional messages provide information about memory usage when a job completes.
The Listener accepts incoming connections and starts tasks if 50 MB of extended memory is available. Otherwise, incoming work is suspended until the memory becomes available.
Two new DBMOVER configuration statements let you specify a minimum amount of available extended memory for PowerExchange jobs, and an alternate method for complex code page conversion. For more information about the new statements, see DBMOVER Configuration File Statements.
