Barry, Our Capacity performance group said that the slow response time for some volumes was caused by the small VTOCIX. The suggestion was made to increase it.

The job matches what I use (except I don't include the VTOCIX DSN in the first step). But what makes you think the VTOCIX is undersized? The CVAFDSM macro will tell you how many VIRs are still available in the dataset. -----Original Message----- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of John Dawes Sent: Tuesday, December 22, 2009 7:04 AM To: IBM-MAIN@bama.ua.edu Subject: INCREASING SIZE OF VIR - VTOC INDEX RECORD Good Evening To All, We have noticed that some of the VIRs on several volumes are very small. We would like to increase the size. I am not sure if I am on the right track this is why I need your help. The VIR exsists on the volume and in order to increase the size I will need to purge it and reallocate it. Below are the 2 jobs I would like to use. Would they work? Is there another way of going about it? I would welcome your suggestions. Job to delete the VTOCIX //STEP1 EXEC PGM=ICKDSF,REGION=3M //MYVOL DD UNIT=(3390,,DEFER),VOL=SER=PROD21, // DSN=SYS1.VTOCIX.PROD21,DISP=SHR //SYSIN DD * //SYSPRINT DD SYSOUT=* //SYSIN DD * BUILDIX DDNAME(MYVOL) OSVTOC PURGE /* Job to build the VTOCIX /* //STEP01 EXEC PGM=ICKDSF,REGION=4M,PARM='NOREPLYU' //PROD21 DD DSN=SYS1.VTOCIX.PROD21,UNIT=SYSALLDA, // VOL=SER=PROD21,DISP=NEW,SPACE=(CYL,(2)) //SYSPRINT DD SYSOUT=* //SYSIN DD * BUILDIX IXVTOC,DDNAME(PROD21) /* // ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html __________________________________________________________________________________ See what's on at the movies in your area.
