Exalogic: vServer Creation Takes a Long Time or Fails After a Few Days of Uptime
Last updated on OCTOBER 23, 2015
Applies to:Oracle Exalogic Elastic Cloud Software - Version 188.8.131.52.0 to 184.108.40.206.1
Enterprise Manager Ops Center - Version 12cR3 (12.3) to 12cR3 (12.3) [Release 12.0]
There is a known issue with EM Ops Center bits that are included in a fresh install of EECS 220.127.116.11.0 and in the April 2015 PSU (18.104.22.168.1) for Exalogic Virtual. This issue does not affect Exalogic racks running January 2015 PSU, although at 22.214.171.124.0, and other older EECS versions.
Guest vServer creation in a fresh install of 126.96.36.199.0 or after applying April 2015 PSU (188.8.131.52.1) completes successfully in a few minutes without any issues. However, after a few days of uptime, the following issues are observed even without any changes to the environment:
- vServer creation takes a very long time (approx. 30 mins or longer)
- vServer creation fails
In addition to Guest vServer creation, other EMOC jobs listed below also take longer to complete or eventually fail:
- Create vNet
- Delete vNet
- Create Account
- Delete Account
- Start Guest vServer
Several SSH connections are observed to be open between the Proxy Control processes and the InfiniBand Gateway switches. Tens of connections are observed to each Gateway Switch.
Perform the following steps to confirm that the env is affected by this issue:
- Login as root to each Gateway Switch.
- Run the following command:
- If the output is higher than 20, the environment is affected by this issue.
