EM 12c: EM Agent Blocked- After the Node is Powered Off Abruptly and Re-started. agntstmp.txt File Turns to ZERO Bytes in Size (Doc ID 1672260.1)

Last updated on JANUARY 29, 2015

Applies to:

Enterprise Manager Base Platform - Version to [Release 12.1]
Information in this document applies to any platform.


The server, where the 12c Agent is installed, is rebooted abnormally (switching off the power button) without shutting down the agent. Once the Agent starts up automatically, it gets blocked and cannot upload to the  OMS.
For the Agent -> OMS communication to work fine again, Agent has to be re-synchronised from the Console UI using the steps in:

<Note 1645261.1> : EM 12c: How to Properly Re-synchronize an Enterprise Manager12c Cloud Control Management Agent
<Note 1376968.1> : How to Perform Agent Resynchronization in 12C Cloud Control ?

This issue occurs intermittently and is not always reproducible for all Agent installations.


Host on which the Agent is installed, had a failure or was abnormally rebooted.
