EDG6799E

Explanation
The EDGUTIL utility was unable to open the DFSMSrmm
control data set. The return_code is a VSAM OPEN
error return code. DFSMSrmm issues the return_code 16
when incorrect share options are set because DISP=OLD is specified.
EDGUTIL MEND and EDGUTIL VERIFY require DISP=SHR for the control data
set.
In the message text: return_code
The VSAM OPEN error return code in decimal.
reason_code
The VSAM reason code in decimal.

System action
The utility ends.  DFSMSrmm sets return code 12.

Operator response
None.

System programmer response
If the return code is 16, check that
DISP=SHR is specified for the MASTER DD statement or for the MASTERB
DD statement when BLSR is used. Return and reason codes are documented
in z/OS DFSMS Macro Instructions for Data Sets. 

Programmer response
If the return code is 12, correct the job
control language (JCL) used to submit the job and re-submit the job.
