Checking BPXPRM syntax

Sat, 09 Apr 2022 13:26:39 -0500

A handy operator command to check syntax to a BPXPRMxx parm member.

After making some mount point changes recenly I issused the command

SETOMVS SYNTAXCHECK=(P3)

Where P3 is the member in SYS1.PARMLIB that was changed (i.e BPXPRMP3)

Another useful command

D OMVS,MF

Will display information about the last 10 or less mount or move failures

zFS Increasing Size

Sat, 08 Jan 2022 13:16:42 -0500

Needed to increase the size of a zFS mounted dataset the other day. I will just provide the link to IBM website for the details but instead of duplicating everthing here, but I wasn’t aware this could be done with the pax command instead of the DFSMS REPRO command.

Snippet example from the IBM site

//SYSTSIN DD *
OSHELL /usr/sbin/mount -t ZFS -f PLEX.OLD.AGGR002.LDS0002 +
 /service2 ; +
 /usr/sbin/mount -t ZFS -f PLEX.NEW.AGGR002.LDS0002 /service3 ; +
 cd /service2 ; +
 pax -rwvCMX -p eW . /service3 ;

OMVS Encoding

This character brackets [ ] and others that don’t convert to a readable form was driving me crazy.

enter this command when starting a USS session: omvs convert((BPXFX111))

Example, in man pages converts this line:

pax Ý-cdEnvz¨Ý-H|-L¨Ý-f archive¨ Ý-o type¨ Ý-s substitute¨ … Ýpattern …¨

to this line:

pax [-cdEnvz][-H|-L][-f archive] [-o type] [-s substitute] … [pattern …]

much easier to read. 👍
