Correcting an incorrect parameter value

z/OS JES3 Initialization and Tuning Reference
SA32-1005-00

If you restart JES3 using an initialization stream that has an incorrect value for any of the parameters listed in Table 1, JES3 uses the parameter's default (individual parameter descriptions in Initialization Statements define valid parameter values.) By using the parameter's default, JES3 can continue to run. Thus, you have a running system that you can use to correct the initialization stream.

To warn you about an incorrect subparameter, JES3 issues message IAT3255. This message identifies the affected parameter, the incorrect subparameter, and the default value.

If you do not want JES3 to continue to run with the subparameter default, restart JES3 using the corrected initialization stream.
