Java CAPS HL7 Adapter Making Multiple Connections (Doc ID 1303311.1)

Last updated on MARCH 26, 2015

Applies to:

Oracle Java CAPS Enterprise Service Bus - Version R6.2 and later
Information in this document applies to any platform.

Symptoms

For TCP HL7 client (outbound) mode.

Under some conditions, the adapter will spam the receiving system with multiple connection requests (i.e. multiple connection requests per second).  However the netstat command shows 2 connections from Java CAPS.

For example:
$ netstat -na | grep 10550
10.1.2.3.47787 10.10.20.30.10550 65536 0 49640 0 ESTABLISHED
10.1.2.3.47788 10.20.30.40.10550 8192 0 49640 0 ESTABLISHED

This causes problems for the receiving application which believes it already has an established connection with JCAPS adapter, and responds negatively to connection requests when already 'connected'.
