Re: Probably a stupid question - concerning Master Catalog Passwords


 

开云体育

In case anyone needs this – here is the JCL to be able to remove the Master Catalog password – this was also difficult to find, as it seems it’s not really ever used. And probably to the experienced SysProg’s, its trivial.???? This removes the password completely.?? Nice to know Doug, that I am not the only one to have experienced this issue, and yeah, I believe all error conditions need to be fully understood and documented. ?I thought the same as you, that I had simply made some mistake in the sysgen process.

//ALTMCPW??? JOB (1),DAVE,CLASS=A,MSGCLASS=A

//STEP01?? EXEC PGM=IDCAMS,REGION=4096K

//SYSPRINT DD SYSOUT=*

//SYSIN??? DD *

???? ALTER SYS1.VSAM.MASTER.CATALOG -

??????? NULLIFY(UPDATEPW)

Thanks,

Many thanks for digging into this. I was just living with the issue and figured that I had built my MVS incorrectly; it's nice to understand what the cause is.
