4.   Installation and configuration

Follow the instructions in this section to download and install this interim fix on your cluster.

System requirements

Linux-x86_64

Installation and configuration

a.     Log on to the primary host as the cluster administrator and disable all applications:

> egosh user logon -u Admin -x password

> soamcontrol app disable all

b.     Download the packages to each of your management and compute host (or just one host if you are using a shared file system) to, for example, to a /symfixes directory.

c.     Run the egoinstallfixes command to install the soamcore-7.3.1.0_x86_64_build601951.tar.gz files:

> egoinstallfixes /symfixes/soamcore-7.3.1.0_x86_64_build601951.tar.gz

Note: Running the egoinstallfixes command automatically backs up the current binary files to a fix backup directory for recovery purposes. Do not delete this backup directory; you will need it if you want to recover the original files. For more information on using this command, see the egoinstallfixes command reference.

d.     Run the pversions command to verify the installation:

> pversions -b 601951

e.     Update the application profile to add the  SOAM_CANCEL_BIND_SESSION_END environment variable with a value of true. This parameter releases an unprovisioned slot if a closed session owns the slot for more than 60 seconds:

<SOAM version="7.3.1">

    <SSM ......>

          <osTypes>

              <osType name="all" ......>

                  ......

                  <env name="SOAM_CANCEL_BIND_SESSION_END">true</env>

              </osType>

          </osTypes>

With this parameter configured, the following message will be logged in the SSM log:

2024-03-22 01:39:35.919 GMT INFO [28787:140414022817536] ssm.ssmcore.ARM - ARM::getEnvCancelBindSessionEnd environment variable SOAM_CANCEL_BIND_SESSION_END is set with true, corresponding feature is enabled.

Also keep the SSM_SIM_HEARTBEAT_INTERVAL_SECONDS and SSM_SIM_NO_RESPONSE_TIMEOUT_SECONDS parameter set in the application profile, as they will also help with the issue.

f.       Enable the applications:

> soamcontrol app enable application_name

 

5.   Uninstallation

If required, follow the instructions in this section to uninstall this interim fix from your cluster:

a.     Log on to the primary host as the cluster administrator and disable all applications:

> egosh user logon -u Admin -x password

> soamcontrol app disable all

b.     Roll back this interim fix:

> egoinstallfixes -r 601951

c.     From the primary host, enable the applications:

> soamcontrol app enable application_name
