Previously, customers were unable to test the latest features and functions before ordering CICS TS, so now IBM is offering you the chance to download a try-before you-buy, no charge version of CICS TS V5.1! CICS TS Developer Trial V5.1 is for evaluation (non-production) use only, offering a full set of features but with restricted performance and limited operational lifespan
Please visit Shopz and search for CICS products to find the Developer Trial.
Check out the announcement letter here.
