HCOM® for Online Transactions

HCOM is transaction switching software that allows online transaction interchange between NonStop applications and applications running under CICS, IMS/DC, and IDMS/DC. HCOM lets users focus their attention on application development without concern for intersystem communications complexity. Databases may be accessed simultaneously in both retrieval and update modes across both environments.

HCOM also supports a store and forward facility, reducing response time to the application user, while guaranteeing the delivery of the data message. No changes are required to IBM applications for transactions originating on a NonStop host. No changes are required to NonStop servers for transactions originating on an IBM host.
