When looking in upgrading your environment from Autosys r12.0 or r12.0 SP1 to version r12.1, you do not need to upgrade the CCI component.
When running the ./CCI_SETUP_LINUX.sh script from the mounted iso file under /modules/CCI, you will get following message
[root@hostname CCI_LINUX]# ./CCI_SETUP_LINUX.sh
$CASHCOMP is available and set as //opt/CA/SharedComponents
$AUTOSYS is available and set as /opt/CA/WorkloadAutomationAE/autosys
CCI already exist on the machine. Please follow readme to patch the existing CCI component
Release : 12.1
CCI package on the 12.0 SP1 iso file is identical to the CCI 12.1 iso file.
There has been no change in any of the CCI binaries and/or libraries.
There is no need to run the CCI_SETUP_LINUX.sh script again.
The message displayed can be ignored.
