How to Configure the Online Interfaces Without CA MSM

The topics in this section describe the manual tasks you must perform if you are not using CA MSM to configure your product.

This section also describes the online interface options, the cross-memory drivers, and how to install the online interfaces, including these topics:

Online and cross-memory interfaces
Cross-memory drivers for ISPF, TSO, and CA Roscoe interfaces
Installation of these options:
- ISPF online retrieval option
- TSO online retrieval option
- CA Roscoe online retrieval option
- Cross-memory services
- ISPF/cross-memory online retrieval option
- TSO/cross-memory online retrieval option
- VTAM online retrieval option
- CA Roscoe/cross-memory online retrieval option
- CICS pseudo-conversational option
- IMS online retrieval option

Online Interfaces

The following table lists the online interfaces, whether cross-memory services (XMS) must be installed and any special advantages of using the interface.

Online Interface	XMS	Advantages
ISPF	NO	Provides full online access without the need for a cross-memory region
ISPF/XMS	YES	Does not require the STEPLIB to be APF authorized To simplify migration, you can run multiple versions of CA Deliver concurrently.
TSO	NO	Provides full online access without the need for a cross-memory region
TSO/XMS	YES	Does not require the STEPLIB to be APF authorized To simplify migration, you can run multiple versions of CA Deliver concurrently.
VTAM	YES	Supports extended data stream to queriable terminals
CICS	YES	To simplify migration, you can run multiple versions of CA Deliver concurrently
IMS/DC	YES
CA Roscoe	NO	Provides full online access without the need for a cross-memory region
CA Roscoe/XMS	YES	Does not require the STEPLIB to be APF authorized To simplify migration, you can run multiple versions of CA Deliver concurrently.

Cross-Memory Services Interface (XMS)

The cross-memory services interface manages several interfaces; this allows you to control online access with a single operator interface. Advantages of the interfaces are discussed later in this chapter.

The parameters in the startup procedure for the cross-memory task allow you to control:

The maximum number of users allowed on the system
Whether to cancel users when they are inactive for a specified time (CANCEL and LONGWAIT)

Note: For information about startup parameters, see Installing Cross-Memory Services later in this chapter.

The operator commands available to modify the cross-memory task allow you to:

Cancel users
Suspend additional logons
List online usage statistics
Modify selected cross-memory startup JCL parameters

Note: For more information about operator commands, see the chapter "Operator Commands" in the Reference Guide.

Cross-Memory Drivers for Interfaces

You can use cross-memory services drivers to run the TSO, ISPF, and CA Roscoe online interfaces.

The advantages of using these drivers are:

Users are authorized by cross-memory drivers.
When you use the cross-memory services drivers for the ISPF, TSO, or CA Roscoe interfaces, users are authorized by cross-memory and do not also need authorization from the online interface (for example, TSO).
Multiple versions of CA Deliver can run simultaneously.
When you use the cross-memory services drivers for the ISPF, TSO, or CA Roscoe interfaces, you can run multiple versions of CA Deliver concurrently. This ability supports migration; it makes it easier to migrate when you are converting to a new version level of CA Deliver.

You can also run multiple versions of the online interfaces simultaneously.

Restrictions

These restrictions apply when you execute the program using the cross-memory drivers for TSO, ISPF, and CA Roscoe:

TSO SUBMIT is not used. The SUBMIT occurs from the connected cross‑memory region.
Direct reprints from the user have the JES banner pages of the cross‑memory region. The internal system banner page can be used to check the user requesting the reprint.

User Exits

User exits run in the cross-memory region and do not have access to TSO or CA Roscoe allocations.

Install the ISPF Online Retrieval Option

The ISPF online retrieval option runs under the IBM Interactive System Productivity Facility (ISPF) for z/OS Version 3.0 and higher.
