Insufficient Swap Space is configured on Oracle Application Server

Article by Rampant Author Brian Carr

If the amount of swap space configured on an Oracle Application Server is insufficient Oracle may hang and force the server to reboot.

Oracle documentation states that Linux servers with more than 8G RAM should also have swap space equal to 75% of memory. For servers with memory between 1 and 2G, swap space should equal 1.5 RAM and for memory between 2 and 8G, Swap space should equal RAM. Insufficient swap space can cause out of memory errors and operating system errors such as unable to fork a process. This can also hang the server and force the server to reboot.
