Migration Information

Starting in Version 14.0, CA SYSVIEW does not provide or require the execution of a dynamic installation job or step. The DYNAMIC job step was removed from the JCL for the CA SYSVIEW started tasks. The installation provides updated JCL for the started tasks.

Note: The job fails when you use the old JCL without removing the DYNAMIC job or step. The execute program, GSVXINST, no longer exists.

The SYSVIEW load library data set must be APF authorized before starting CA SYSVIEW.

For previous releases of CA SYSVIEW

In releases before Version 14.0, CA SYSVIEW required the following system resources to be defined:

User SVC
The existing SVC definitions can be removed when prior releases are no longer used.
```
SYS1.PARMLIB(IEASVCnn)
SVCPARM nnn,REPLACE,TYPE(3),APF(NO),EPNAME(GSVXSVC)
```
LPA Modules
The existing LPA definitions can be removed when prior releases are no longer used.
```
SYS1.PARMLIB(IEALPAnn)
INCLUDE LIBRARY(sysview.CNM4BLPA)
MODULES(GSVXSVC,GSVXAAST,CAIXNM4$)
```
The APF authorization of SYSVIEW load library data set
The APF authorization is still required.
```
SYS1.PARMLIB(PROGxx)
APF ADD DSNAME(sysview.CNM4BLOD) VOLUME(volume)
```

The required system resources could have been defined using one of the following methods:

Providing manual definitions in the SYS1.PARMLIB members

SVC - SYS1.PARMLIB(IEASVCnn)
LPA - SYS1.PARMLIB(IEALPAnn)

Execution of a stand-alone dynamic install job

sysview.SAMPJCL(INST0100) or
sysview.CNM4SAM(DYNMINST)

The following CA SYSVIEW Services started task contained a job or step DYNAMIC that was used to install dynamically the required resources. The step could be run even if the resources had been manually defined.
```
SYSVIEW - Main Services Address Space
SYSVUSER - User Interface Address Space
```

User Supervisor Call (SVC) Removal

In releases before Version 14.0, you defined a user SVC in the CA SYSVIEW System Configuration Options member GSVXGSVX. This member resides in the system parmlib concatenation.

Starting at Version 14.0, remove the following obsolete System Configuration Option from any options member:

SVC-Number

If you do not remove this option, the CA SYSVIEW initialization continues while issuing the following series of warning messages:

GSV445W Configuration member: GSVXGSVX

GSV446W Configuration option: SVC-Number nnn

GSV447W Configuration error: Option name is obsolete.

LPA Load Library Data Set Removal

The installation of CA SYSVIEW no longer requires a separate data set to contain the required LPA load modules.

The following data set is no longer distributed:

sysview.CNM4BLPA

Anchor Address Space Removal

CA SYSVIEW Version 14.0 utilizes the CA Common Services CAMASTER address space to anchor any required resources.

In releases before CA SYSVIEW Version 14.0

CA SYSVIEW utilized an anchor address space:

SYSVAAST - Anchor Address Space (prior to r14.0)

The purpose of the anchor address space was to anchor data spaces that CA SYSVIEW services created and used.

The anchor address space:

Did not execute any code or programs.
Was defined as non-cancelable and non-memtermable
Was created automatically at initialization by the main services address space
Remained and was reused through the life of an IPL.

Library Concatenation

A CA SYSVIEW installation is comprised of several types of libraries or data sets designed to contain a specific type of data. This library is referred to as a library type(libtype).

A library type can consist of multiple data sets. These data sets dynamically concatenate when a read request is made for the specified library type.

Only one data set can be defined for each data set type. Therefore, a maximum of three data sets can be concatenated.

If defined, the data sets are concatenated in the following order:

libtype	DD DISP=SHR,DSN=user.data.set
	DD DISP=SHR,DSN=site.data.set
	DD DISP=SHR,DSN=system.data.set

The possible data set types are:

User (Optional)

The optional user-defined data sets contain definitions or overrides to site or system definitions.

The users define and maintain the user data set names in their CA SYSVIEW profile.

Site (Optional)

The optional site defined data sets contain definitions or overrides to system definitions.

The site data set names are defined in the CA SYSVIEW System Configuration Options member: GSVXGSVX

The system configuration options member must be located in the concatenation of the z/OS system parmlib data sets.

Example: SYS1.PARMLIB

System

The required system defined data sets contain definitions or configuration options. The set of system data sets contains the original members the product installation delivered. The system data set names are defined in the CA SYSVIEW System Configuration Options member: GSVXGSVX.

The system configuration options member must be located in the concatenation of the z/OS system parmlib data sets.

Example: SYS1.PARMLIB
