Modifying Initialization Parameter Settings while IBM Connect:Direct is Running

Edit online

You can update certain initialization parameters in the initialization parameter member, and then use the MODIFY INITPARMS command to update IBM® Connect:Direct® with the new initialization parameter settings without restarting, using one of the following methods:

Using the MODIFY INITPARMS Command from the Batch Interface
Issuing the MODIFY INITPARMS Command through the IUI
Performing Configuration Management of Initparms through Control Center. For more information, refer to the documentation for Control Center.

You cannot update local initialization parameters with the MODIFY INITPARMS command using the first two methods listed above but you can using Control Center.

To ensure continuity in operation, create backup copies of the global and local initialization parameter members to use if IBM Connect:Direct cannot initialize after initparm updates. For information, see Backing up the Global and Local Initialization Parameter Files.

The following list contains the initialization parameters that you can update while IBM Connect:Direct is running:

Note: The MODIFY INITPARMS command updates parameters in the following list, after all parameters (global and local) are parsed for correct syntax. Since the MODIFY INITPARMS command reads the entire global initialization parameter member (and local INITPARM members), the entire global initialization parameter member is used for the update (along with local INITPARM members). Therefore, you cannot update individual parameters with the MODIFY INITPARMS command.
