If you have existing applications that use the CICS® Connector for CICS TS, you must upgrade them to use the CCI Connector for CICS TS instead.
Connector used by current program | Connector interface used by current program | Status in CICS TS 3.1 | Suggested upgrade strategy |
---|---|---|---|
CICS Connector for CICS TS | CICS Transaction Gateway API (ECIRequest) | Not supported | The CICS Transaction Gateway API is no longer supported. Re-engineer to use the CCI Connector for CICS TS. Program the connector either directly or by means of a rapid application development (RAD) tool that supports it. |
CICS Connector for CICS TS | CCF, programmed either directly or with VAJ Enterprise Access Builder or similar | Not supported | CCF is replaced by CCI. Re-engineer to use the CCI Connector for CICS TS,
which performs better than the CICS Connector for CICS TS and uses an industry-standard interface.
Program the connector either directly or by means of a RAD tool that
supports it.
Note: It is possible to program the CCI Connector for CICS TS using
VAJ Enterprise Access Builder, but this is not recommended because
VAJ/EAB is no longer supported.
|
CCI Connector for CICS TS | CCI, programmed directly | Supported | CCI can be used indefinitely. Programming the CCI directly gives the best performance. |
CCI Connector for CICS TS | CCI, programmed with VAJ Enterprise Access Builder or similar | Supported | To continue using VAJ/EAB, changes must be made to the application. |
