Issue/Introduction

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.

Resolution

If one of the STEPLIB libraries (e.g. the 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.
