Allocating the RTCS system registry

Allocate a VSAM LDS cluster for the RTCS system registry, either by allocating:

One for each z/OS image if you are not going to share the registry
One to be shared sysplex-wide by all members of the sysplex

Note

BMC recommends that the RTCS system registry data set not be under the control of the Storage Management System (SMS). If the register data set must be under SMS control, be sure to specify storage class and management class values that allow the data set to be kept indefinitely. It is very important that the register data set not be deleted.
If you choose to manage the RTCS registry data set using SMS, then you must wait until SMS has fully initialized before starting RTCS.
This VSAM LDS cluster must be allocated for use by the RTCS subsystem to back the primary RTCS registry partition using the z/OS Data-In-Virtual (DIV) service. Because it is a VSAM cluster and will be dynamically allocated by the RTCS subsystem address space using only its DSNAME, this library must be cataloged.

To allocate the RTCS system registry

Select a VSAM LDS cluster DSNAME for the REGISTRY data set.Its low-level index should be REGISTRY, but this is not required. If its DSNAME does not follow the same naming convention that you have already used for the POSZRTCS, POSZLINK, and POSZHTML data sets, or its low-level index is not REGISTRY, you will have to specify the name of the LDS cluster in the SREGVLDS option of the RTCS Initialization member of Logical PARMLIB.
To allocate a new VSAM LDS to back the RTCS system registry, you can customize the sample JCL shown in the following figure. The text that should be customized is shown in bold. This sample JCL is contained in member OSZINJ80 in the TOSZCNTL target library.
//OSZINJ80 JOB (acct),'ALLOC REGISTRY VLDS',

//             SPACE=(4096,(17472,0))
//*
Determine the amount of space, expressed in terms of the number of 4K blocks, to allocate for the VSAM LDS.The minimum amount of space you should allocate for the RTCS system registry VSAM LDS is 17,472 blocks (68.25 MB), which requires 98 cylinders on a 3390.
The RTCS system registry is never likely to require more than 371 cylinders (260.85 MB) of space, even in very large configurations. For sites that do not run more than one MainView CAS (or do not run a CAS at all), 188 cylinders (132.1 MB) should be adequate. Sites that run more than one CAS or that have very large configurations might require 371 cylinders.
Allocate the library using the information you have gathered.
