Symptoms

An Oracle Data Integration (ODI) Agent running on IBM AIX 64-bit operating system is successfully receiving and executing Scenarios for several hours.

Then quite suddenly the Agent appears to hang and no longer acts as a running Java process.

More precisely, the Java process attached to the Agent is still present but is not longer acquiring CPU time, and no longer responds :

• running Sessions do not terminate
• the Agent no longer starts up any new Session and non are set either the Queued or Waiting status.
• a test of the Agent from the ODI Topology Manager hangs.
• The agentstop.sh command also hangs and does not complete.

No warnings or error messages are intercepted in either the standard and/or error outputs, or in the trace files.

For information, a Java5 SR12 FP1 64-bit is used:

java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build pap64dev-20100813 (SR12 FP1 ))
