CICS - Error Handpng

There are many types of abends and errors which one can face while using a CICS apppcation. Errors can arise due to both hardware of software issues. We will be discussing about errors and error handpng in this module.

CICS Errors

Following are the CICS errors which can arise during the execution of CICS apppcations −

Some expected CICS errors arise when the conditions are not normal in the CICS system. For example, if we are reading a particular record and the record is not found, then we get the "Not Found" error. Mapfail is a similar error. Errors in this category are handled by exppcit logic in the program.

Logical errors arise due to some reasons pke spanision by zero, illegal character in numeric field, or transaction id error.

Errors that are related to hardware or other system conditions are beyond the control of an apppcation program. For example, getting input/output error while accessing a file.

Error Handpng Commands

CICS provides several mechanisms to identify the errors and to handle them in our programs. Following are the commands which are used to handle the expected CICS errors −
