If you have existing CICS applications accessing the database (at the version 1, pre-5.0 level) that you wish to execute under CICS/ESA, they must first be re-link-edited with the 5.0 link-edit stub.
Once relinked, these applications execute against the 5.0 release of the Teradata CICS Attachment Facility runtime code under any supported CICS release.
When migrating Preprocessor2 or CLIv2 applications that were linked with the pre-5.0 version of the link-edit stub, observe the following:
| IF the application is written with. . . | AND it is invoked under . . . | THEN . . . |
|---|---|---|
| AMODE31 | CICS/ESA 3.2 or above running the 5.0 version of the Teradata CICS Attachment Facility | it abends with code STUB. |
| any version of CICS prior to CICS/ESA 3.2 | it runs without error. | |
| AMODE24 | CICS/ESA 3.2 or above running the 5.0 version of the Teradata CICS Attachment Facility | the result is unpredictable, but may include any of the following codes:
|
| any version of CICS prior to CICS/ESA 3.2 | it runs without error. |
