Case Study Agent Push Fails for Insufficient /tmp Space on Target Host (Doc ID 464306.1)

Enterprise Manager Base Platform - Version and later
Information in this document applies to any platform.


Agent push is a process which generates quite a bit of logging, but often not much user messaging in case of failure.

Described here is the messaging generated when the target host /tmp directory does not have enough space for the agent install (requires 250MB nominal). There is enough space for the installer to start up, though (112MB nominal).

Based on different situations, in order to ensure a smoothly Grid Control Agent Installation on Unix Platforms, we recommend 500 MB free in the temporary directory (default /tmp), 2GB if possible. It is also perhaps worth checking the swap settings (if less than 2GB).

If the default temporary directory, which is /tmp on Unix and C:\tmp on windows, does not have enough space available and cannot be granted more space, you can change the default directory to a directory where you have the recommended amount of space available.

  1. Take a backup of the file  $OMS_ORACLE_HOME/sysman/prov/agentpush/
  2. Edit this file to change the value provided for the parameter tempdir:
    oracle.sysman.prov.agentpush.nttempdir=C:\\tmp (if the target host is a Windows platform)
    oracle.sysman.prov.agentpush.unixtempdir=/tmp (if the target host is a Unix platform)


The characteristic messaging for a Linux x86 target host from a Linux x86_64 Grid Control installation with all Grid Control component versions at Note that the user messaging and logging may be somewhat different when other platforms are under consideration. If the user interface messaging is not provided, check the indicated log to see if insufficient /tmp space is the cause of the fault.
