Exalogic Virtual: How to Restore 32GB Swap Partition in Exalogic Control EC vServer (Doc ID 2904216.1)

Last updated on OCTOBER 21, 2022

Applies to:

Oracle Exalogic Elastic Cloud Software - Version 2.0.6.3.201020 to 2.0.6.3.221018
Oracle Exalogic Elastic Cloud Software - Version 2.0.6.4.0 and later
Linux x86-64
Oracle Virtual Server x86-64

Purpose

The procedure in this document provides a step-by-step procedure to restore the swap partition size to the original value of 32GB in the Exalogic Control EC vServer. It was observed in a few customer environments that the swap partition size was lower (1.5 GB compared to the original value of 32 GB). Depending on the workload, this decrease in swap space can at times lead to undesired behavior, including abrupt shutdown of processes within the EC vServer due to lack of memory. The root cause of this issue is a misconfiguration in the following Exalogic one-off patch that was released for Platinum Monitoring TLS v1.2 support and applied by the Platinum Patching team:


BUG 31181409 - EXALOGIC PATCH TO MIGRATE EXALOGIC CONTROL (EC) VSERVER FROM OL5/UEK2 TO OL6/UEK2 FOR EECS 2.0.6.3.x

Scope

Procedure in this MOS note applies to OL6-based Exalogic Control EC vServer, including the following:


EC vServer in Exalogic 2.0.6.3.200414 (Apr 2020 PSU) and higher

EC vServer in Exalogic 2.0.6.4.X

Note: Environments running the above releases are affected only if patch 31181409 was previously applied for Platinum monitoring TLS v1.2 support as already described. Patch 31181409 may or may not appear in the output of imagehistory on the EC vServer. A quick test to perform on the EC vServer is to run the "top" or "swapon -s" command and check for the amount of swap space configured. If the swap size displays at around 1.5 GB, the environment is affected. Since the above patch does not touch EMOC Proxy Controller vServers (PC1 and PC2), they are unaffected.
