COMTI 102 (2169) Error May Occur if the CSM Message Is Split Across Two Frames

View products that this article applies to.

Symptoms

When you use an information management system (IMS) open transaction management architecture (OTMA) remote environment type, you may receive the following error from the COM Transaction Integrator (COMTI) feature of Host Integration Server 2000:

Event Type: Error
Event Source: COMTI
Event Category: General
Event ID: 102

Description: (102) COM Transaction Integrator reported the following exception to the client:

Component: IMS_OTMA.Cedarbank.1
Method: getaccts

Exception description: (2169) The TCP transport encountered an unexpected error when checking for special IMS Connect or OTMA segments. Segment type=CSM message, Transaction CEDRBANK. IP Address: 169.4.14.11, port: 5005.

Cause

When COMTI communicates with an IMS system by using OTMA or IMS Connect, COMTI expects a completion status message (CSM) to be sent from IMS that contains the response data from the host. This CSM message has a header and a footer that contain the string "*CSMOKY*" (without the quotation marks). If the CSM footer is split across two TCP/IP frames, a timing condition exists that may cause COMTI to incorrectly return the 102 (2169) error.
