3.     Installation and configuration

Follow these steps to upgrade the nimbus-jose-jwt.jar file to an IBM Spectrum Conductor 2.3.0 cluster:

a)       Log on to the master host as the cluster administrator and stop the HostFactory service:

> egosh user logon -u Admin -x Admin   

> egosh service stop HostFactory

b)       On each management and compute host, move the following file to a backup directory for recovery purposes: 

> mkdir -p /tmp/hflib/

> mv $EGO_TOP/3.7/hostfactory/providers/common/lib/nimbus-jose-jwt-3.1.2.jar /tmp/hflib/

Note: To avoid compatibility issues, move the old file to another directory altogether.

c)       On each management and compute host, create a directory (for example, /csfixes) and download the egocore-3.7.0.0_x86_64_build544900.tar.gz package to the directory.

d)       Run the egoinstallfixes command to install the egocore-3.7.0.0_x86_64_build544900.tar.gz package:

> egoinstallfixes /csfixes/egocore-3.7.0.0_x86_64_build544900.tar.gz

e)       Run the pversions command to verify the installation:

> pversions -b 544900

f)        From the master host, start the HostFactory service:

> egosh user logon -u Admin -x Admin

> egosh service start HostFactory

4.     Uninstallation 

If required, follow these steps to uninstall the upgraded .jar file from the IBM Spectrum Conductor 2.3.0 cluster:

a)       Log on to the master host as the cluster administrator and stop the HostFactory service:

> egosh user logon -u Admin -x Admin

> egosh service stop HostFactory

b)       On each management and compute host, run the egoinstallfixes command to roll back this interim fix:

> egoinstallfixes -r 544900 --silent

c)       On each management and compute host, restore the following file from your backup:

> mv /tmp/hflib/* $EGO_TOP/3.7/hostfactory/providers/common/lib/

d)       From the master host, start the HostFactory service:

> egosh user logon -u Admin -x Admin

> egosh service start HostFactory
