Creating and assembling ETA exits

You can create an ETA exit that takes advantage of ETA’s capabilities. Once you have created the exit, you must use JCL that is provided with ETA to assemble and link the exit and the appropriate IMS release-dependent ETA code.

Before you begin

You must know the location of ETASAMP and ETACNTL. Contact your ETA system administrator.

If you want the ETA exit to make use of customization information that is specified in the ETA IMSID options or in a TSS table, you must use the ETA online interface to specify these options or create the TSS table. For instructions on specifying customization through the ETA online interface, see IMS-customization-by-IMSID. For instructions on creating TSS tables, see Utilities-for-Translate-Subsystem-Services-feature.

To create and assemble ETA exits

Create an ETA exit by modifying statements, as necessary, in one of the following macros:

If you want to create an ETA exit that controls...	Then modify sample exit...
Logon options	ETMELN1X
Logoff options	ETMELF1X
Signon options	ETMESN1X
Signoff options	ETMESF1X
Autosignon options	ETMEAS1X
Unsolicited output options	ETMEIN1X
DFS3649A, DFS3650I, or DFS2467I options	ETMEGM1X
Non-discardable messages options	ETMEND1X

Modify the appropriate JCL in ETACNTL as necessary. You must specify the IMS release-dependent stub that will be assembled with the macro.

Important

Change only the required parameters that are listed in the JCL. Changing the JCL name and other parameters may cause the assembly to fail.

If you want to create an ETA exit that controls...	Then modify JCL in...
Logon options	ETA#ELN1
Logoff options	ETA#ELF1
Signon options	ETA#ESN1
Signoff options	ETA#ESF1
Autosignon options	ETA#EAS1
Unsolicited output options	ETA#EIN1
DFS3649A, DFS3650I, or DFS2467I options	ETA#EGE1
Non-discardable messages options	ETA#END1

Use the JCL to assemble and link the ETA exit that you created.
Repeat this task for other ETA exits as needed.
Repeat this task for other IMS systems as needed.

Where to go from here

You must perform the following actions:

Use the ETA Exit Processing panel to activate the exit. See Deactivating-and-reactivating-exits for instructions.
Modify the appropriate selection option in the ETA IMSID options so that ETA will recognize the exit and use it to specify IMS system customization. See one of the following sections for information and instructions:

If you created exit...	Then see...
