Getting information about VSAM clusters.

[ringd]

Hello!

Does anybody know how to obtain information on VSAM components, such as last referenced date etc.

The 'LISTDSI' function does not support VSAM. The ISPF 'DSINFO' service does not support KSDS at all, but does support ESDS as long as you provide the DATA component as the dataset name (not the cluster name).

All suggestions are welcome.

Cheers,
Dave.

Hi Dave,

You can use LISTCAT to get the info about a VSAM, but i doubt if you can get the last modified info.

syntax:
"LISTCAT ENTRIES("filename&quot ALL"

You can give this command in ISPF and see the o/p.
To get the lrecl of the file, the following piece of code can be used:

DO I=0 TO ALLPARM1.0
INDX1 = INDEX(ALLPARM1.I,"MAXLRECL&quot
IF INDX1 > 0 THEN
DO
MAXLRECL1 = WORD(ALLPARM1.I,2)
LEAVE
END
END


Hope it is useful.
Cheers,
Sudha.

Hi Dave,

A small correction the stem variable ALLPARM1 will get value like this

X = OUTTRAP(ALLPARM1.)
"LISTCAT ENTRIES("file name&quot ALL"
X = OUTTRAP("OFF&quot
