<p>Use the Change CICS System Initialization Table (CHGCICSSIT) command to change the entry in the SIT.
|
|
</p>
|
|
<p>The System Initialization Table (SIT) is used to specify the initial startup conditions and control parameters for your system. Because only one set of conditions can apply to the system at any one time, only one SIT entry is allowed per group and per Group List Table (GLT).
|
|
</p>
|
|
<p>
|
|
<b>Note: </b>It should be understood that changes to the SIT can affect the performance and run-time characteristics of your CICS system. Changes made to a SIT entry should be well tested and understood before being put into a production environment.
