Actually there is two utilities in CA1 called tms cycle and tms CTLG...In that its mentioned that cycle control volume and catalog control datasets ...so my question is what are they i.e. catalog control and cycle control datasets and volumes

A quick read of the CA-1 Administrator and Operator Guide indicates that catalog control and cycle control are attributes that can be assigned to a given tape volume; there are no actual data sets involved in either. Both references indicate the attributes are stored in the master CA-1 data set, the TMC, which contains everything CA-1 knows about the site tapes.

Take a wild guess at what these terms might mean and we will let you know if you are right or wrong.

You are correct about the catalog retention, that the TMS will not return the volume to scratch status while a valid dataset is cataloged to the volume.

I am extremely tempted to suggest handlebars and brake levers for cycle control, but instead I have used google to search for information and have found a good few links that explain exactly what cycle control is.

I assume that you have not taken this path yourself.

EXPDT=99ccc Cycle Control - This TMS keyword may be used to retain ccc cycles (creations) of a tape data set with a unique dsname. The creating job may specify JCL parameter DISP=(…,CATLG,…). However, only 1 creation of the dsname can be cataloged in a system catalog at any given point in time. Upon creation of the ccc+1 data set, the oldest data set is expired, uncataloged, and the owning tape cartridge released for scratch processing and reuse. Special consideration for JCL disposition handling is necessary to ensure the correct data set is cataloged. For that reason, this keyword is seldom used. A data set associated with this keyword retention will be reflected in TMS reporting with EXPDT=CYCLE/ccc.


//ddname DD DSN=aann.ann,DISP=(,KEEP),UNIT=TAPE,EXPDT=99ccc

That's very coincidental Peter, because that was one of the threads that I found.
Perhaps we should change your status from "active user" to "active librarian" icon_biggrin.gif

I just wonder why the OP could not find it for himself icon_cry.gif

Hi,

just something to remember with CYCLE control, it depends on the TMOOPTxx member options used,

The CDAY parameter can be set to TAPE or DAY.

When set to TAPE, each individual creation of a data set under Cycle Control is considered a single cycle.

When set to DAY, all creations of a data set with the same creation date are collectively considered a single cycle.

The CJOB parameter can be set to JOB or DSN.

When set to JOB, multiple job names creating the same data set have separate cycles.

When set to DSN, the creating job name is not considered by TMSCYCLE.
