Abstract
Connect:Direct for z/OS: Restricted Concurrent Sessions
Body
IBM Sterling Connect:Direct for z/OS can be licensed two ways for concurrent sessions. The typical license is for unrestricted concurrent sessions. You can also get a ‘restricted’ concurrent sessions license that limits the number of concurrent sessions at a potentially lower cost.
Concurrent sessions refers to the number of processes running concurrently, not the number of active remote nodes. The total of Inbound and Outbound processes is counted against the concurrent sessions limit.
Current releases do not have a key to enforce this limit. If you are on a restricted license, you must code the MAXPROCESS initialization parameter to ensure that you do not exceed your licensed concurrent sessions. You may be liable for exceeding your licensed capacity.
MAXPROCESS should be coded in the initialization parameters to match the licensed sessions. This will prevent exceeding the licensed capacity. Note that unrestricted licenses do not require MAXPROCESS, but the default may not be optimal for your needs.
For example, if you are licensed for 10 concurrent sessions, code the following:
MAXPROCESS=10 – This must match the licensed sessions.
See Don't limit your inbound or outbound sessions to 6 in Connect:Direct for z/OS. Review the default values for MAXPRIMARY, MAXSECONDARY, and MAXPROCESS. for more information on other process limits you may want to configure.
See 5655-X11 and 5655-X12: Differences between Sterling Connect:Direct for z/OS Program Numbers. for the current Program Numbers.
