Perform the following prerequisite tasks:

Stop all processes that access the installation directory and subdirectories, including command prompts and command line programs.
Close the Informatica clients on all machines where you want to apply the hotfix.
Close the Informatica directory and the subdirectories.
Back up the repository and warehouse files. Ensure that you back up the required repositories from the Administrator tool. These backup files are required if you roll back the hotfix. Back up the following databases and files in your environment:
PowerCenter repository
Model repository
Metadata Manager imm.properties file
Metadata Manager warehouse
Data Transformation ServiceDB directory
Stop the Informatica services on all nodes in the domain.
Shut down the Informatica domain using the
infaservice shutdown
command. By default, the infaservice executable file is located in the following directory:
<Informatica installation directory>/tomcat/bin
.
If the machine uses HTTPS to connect to Informatica Administrator, verify that the keystore file is in the default location and that it uses the default file name. The default location for the keystore file is
<Informatica installation directory>/tomcat/conf
. The default file name for the keystore file is Default.keystore.
Set the SKIP_VENDOR_CHECK environment variable to true to remove the sudo prompt from the hotfix installation on UNIX.
If you don't have sudo privileges, set the environment variable to true before you apply or roll back a hotfix. If you have sudo privileges, you don't need to set the environment variable.
