Process Start

The CT address space starts an MVS Started Process – in the Samplib is an ISPWRX member containing the JCL as shown in the following figure.

JCL in Member ISPWRX

This process runs TSO and then initiates a REXX, passing the parameters that identify the Physical Package. An ISPW CI Task must be present on the system to facilitate communication with the CM Task (which can be on a remote LPAR.

Passed Parameters

The three parameters listed in the following table are passed from ISPW to the Started Proc and then to the REXX. These uniquely identify the Physical Package.

Passed Parameters

Parm	Description
DREQID	Deploy RequestID
PKGID	PackageID
SYSTNAME	System Name

Initial REXX

The initial REXX parses the passed parameters and then calls theISPW Program WZZRX. This program creates anISPW Environment within which the API Calls can be made. WZZRX is passed the three parameters that the Proc was passed plus the name of the Implementation REXX - WZU@ACI# in the example and supplied in the Samplib.

WZU@ACI#

The REXX makes calls to ISPW to enable it to perform the Implementation and Activation Processes. The sample in the Samplib contains example processes for different deployment types. The next section describes the standard Deploy API calls that the deployment REXX would use.
