MFS Reversal utility
The MFS Reversal utility converts Message Format Services (MFS) control blocks back into IMS™ MFS utility control statements.
- MFS Reversal utility overview
The MFS Reversal utility converts MFS MID, MOD, DIF, and DOF control blocks back into IMS MFS utility control statements. The MFS Reversal utility is helpful in cases where the MFS source files are lost or compromised. - Restrictions and considerations for the MFS Reversal utility
Certain restrictions and considerations apply when using the MFS Reversal utility. - Converting MFS control blocks to control statements
To convert MFS control blocks (MIDs, MODs, DIFs, and DOFs) back into the IMS MFS utility control statements or to copy MFS control blocks by using the MFS Reversal utility, you must prepare JCL for MFS Reversal and submit the job. - JCL requirements for the MFS Reversal utility
When you code the JCL to run the MFS Reversal utility, include the EXEC statement and appropriate DD statements. - Control statements for the MFS Reversal utility
Control statements for the MFS Reversal utility specify the functions to be performed; they must be placed in the SYSIN data set. - Output from the MFS Reversal utility
Output from the MFS Reversal utility consists of the SYSOUT data set, the SYSPRINT data set, the MFSSRCE data sets, the COPYFMT data set, and the COPYPRT data set. - Important notes about the generated source
The MFS Reversal utility makes certain assumptions when generating source.
