Remediation/Fixes

Applicability
Operating systems: Linux x64

Cluster type: Single grid cluster

Prerequisite
To install or uninstall the .rpm packages for IBM Spectrum Symphony 7.1.2 and 7.2.0.2, you must have root permission and RPM version 4.2.1 or later must be installed on the host.

Before installation
a. Log on to the master host as the cluster administrator.
b. Disable your applications, stop services, and shut down the cluster:
> source profile.platform
> soamcontrol app disable all
> egosh service stop all
> egosh ego shutdown all
c. For Platform Symphony 6.1.1, 7.1 Fix Pack 1 and 7.1.1, back up the JRE folder (under $EGO_TOP/jre/<EGO_version>/linux-x86_64/) on all hosts.
For example, in a Platform Symphony 7.1.1 cluster, back up the JRE folder at $EGO_TOP/jre/3.3/linux-x86_64/.
d. For IBM Spectrum Symphony 7.1.2 and 7.2.0.2, uninstall the existing JRE.
a) Query the existing JRE package and uninstall it from the dbpath location, for example:
> rpm -qa --dbpath /tmp/rpm |grep egojre
egojre-1.8.0.3-408454.x86_64
> rpm -e egojre-1.8.0.3-408454.x86_64 --dbpath /tmp/rpm --nodeps
b) For IBM Spectrum Symphony 7.2.0.2, remove the leftover link under the jre folder, for example:
> rm -rf $EGO_TOP/jre/8.0.5.0

Install this interim fix
a. Log on to each host as the cluster administrator and replace your current JRE folder with the files in this interim fix.
For Platform Symphony 6.1.1, 7.1 Fix Pack 1 and 7.1.1, remove the files in the existing JRE folder and extract the interim package to the JRE folder on all hosts.
For example, in a Platform Symphony 7.1.1 cluster, enter the following commands:
> rm -rf $EGO_TOP/jre/3.3/linux-x86_64/*
> tar zxfo symSetup_jre8sr5fp11_linux-64_build491204.tar.gz -C $EGO_TOP/jre/3.3/linux-x86_64
For IBM Spectrum Symphony 7.1.2 and 7.2.0.2, use the same dbpath and prefix as the installation, for example:
> rpm –ivh --dbpath /tmp/rpm --prefix /opt/platform egojre-1.8.0.511.x86_64.rpm
b. Delete all subdirectories and files in the GUI work directory:
> rm -rf $EGO_TOP/gui/work/*
> rm -rf $EGO_TOP/gui/workarea/*
**NOTE:**If you configured the WLP_OUTPUT_DIR parameter and APPEND_HOSTNAME_TO_WLP_OUTPUT_DIR is set to true in the $EGO_CONFDIR/conf/wlp.conf file, you must clean up the $WLP_OUTPUT_DIR/webgui_hostname/gui/workarea/ directory.
c. Launch your browser and clear the browser cache.
d. Log on to the master host as the cluster administrator, start the cluster and enable your applications:
> source profile.platform
> egosh ego start all
> soamcontrol app enable <appName>
