EGO, Linux x86_64, sym-7.2.1-build559294-ms
4. Installation and configuration
Follow the instructions in this section to download and install this interim fix in your cluster.
System requirements
Linux x86_64
Installation
a. Log on to each compute host as the cluster administrator and shut it down:
$ egosh ego shutdown hostname
b. On each compute host, download the egocore-3.7.0_x86_64_build559294.tar.gz package to, for example, the /symfixes directory.
c. Run the egoinstallfixes command to install the egocore-3.7.0_x86_64_build559294.tar.gz package:
> egoinstallfixes /symfixes/egocore-3.7.0_x86_64_build559294.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 559294
IBM Spectrum egocore 3.7.0.0

notes:
fixes: P103873
files: /3.7/linux-x86_64/etc/pem
e. On each compute host, add following configuration to the ego.conf file to enable this fix. This fix only works in simplified workload execution (WEM) mode:
EGO_CLUSTER_ADMIN=clusterAdmin
EGO_CLUSTER_ADMIN_VALIDATE_IN_SIMPLIFIED_WEM=n
where:
· EGO_CLUSTER_ADMIN sets the cluster administrator user value. Specify the same value as the first administrator listed in the ego.cluster.cluster_name file.
· EGO_CLUSTER_ADMIN_VALIDATE_IN_SIMPLIFIED_WEM indicates how the system will retrieve the cluster administrator user value. Specify "n" or "y"; the default value is "y".
If set to "n", PEM will use the EGO_CLUSTER_ADMIN value from the ego.conf file as the cluster administrator value and will not call the primary LIM for the cluster administrator account.
If not set, of if set to "y" (which is the default), PEM will call LIM for the cluster administrator name in simplified workload execution (WEM) mode.
f. Start each compute host:
$ egosh ego start hostname
5. Uninstallation
If required, follow the instructions in this section to uninstall this interim fix from your cluster.
a. Log on to each compute host as the cluster administrator and shut it down:
$ egosh ego shutdown hostname
b. On each compute host, roll back this interim fix:
> egoinstallfixes -r 559294
c. On each compute host, remove the configuration set in the ego.conf file:
EGO_CLUSTER_ADMIN=clusterAdmin
EGO_CLUSTER_ADMIN_VALIDATE_IN_SIMPLIFIED_WEM=n
d. Start each compute host:
$ egosh ego start hostname
