Applies to:
Oracle Data Integrator - Version 11.1.1.3.0 to 12.1.2.0.1 [Release 11gR1 to 12c]Information in this document applies to any platform.
Symptoms
After having set up an Oracle Data Integrator (ODI) mixed Agent load balancing configuration comprising:
- A parent ODI 11g JEE Agent
- Multiple child ODI 11g standalone Agents
when the system has been running correctly for approximately 12 hours, the WebLogic Managed Server hosting the J2EE Agent displays the following message:
Too Many Open Files
in its log file.
Moreover, network administrators detect unexpectedly large number of TCP socket connections in a CLOSE_WAIT state on the host server supporting the J2EE Agent which correspond to connections to processes on the host machines where ODI child Agents are running:
tcp 1 0 <IP>:<PORT> <IP>:<AGENT1_PORT> CLOSE_WAIT 8077/java off (0.00/0/0)
tcp 1 0 <IP>:<PORT> <IP>:<AGENT1_PORT> CLOSE_WAIT 8077/java off (0.00/0/0)
tcp 1 0 <IP>:<PORT> <IP>:<AGENT1_PORT> CLOSE_WAIT 8077/java off (0.00/0/0)
tcp 1 0 <IP>:<PORT> <IP>:<AGENT2_PORT> CLOSE_WAIT 8077/java off (0.00/0/0)
tcp 1 0 <IP>:<PORT> <IP>:<AGENT1_PORT> CLOSE_WAIT 8077/java off (0.00/0/0)
