What is the reason for getting error messages
IDI2104E UNABLE TO INTERFACE WITH IMS. DBOE301E UNABLE TO ESTABLISH IMS ENVIRONMENT NEEDED FOR DBRC AND/OR SEGMENT EDIT ROUTINES.
If one of the STEPLIB libraries (e.g. the CA IMS Tools loadlib) is running unauthorized, all STEPLIB libraries will get unauthorized too.
DD statement DSFRESLB needs to be used to re-authorize the IMS Reslib. IF DFSRESLB DD is missing, the messages IDI2104E and DBOE301E will occur and the job abends with RC=12.
