After upgrading Informatica PowerCenter, the INFA_HOME operating system environment variables must be set to a new PowerCenter installation path:
For example, when upgrading from 9.0 to 9.0.1, the path:
INFA_HOME=/opt/Informatica/9.0 is changed to path INFA_HOME=/opt/Informatica/9.0.1
Other PowerCenter environment variables are relative to the INFA_HOME environment variable. Therefore, one need not apply any further changes, but it is worthwhile to check if the above statement is true.
An example setting for other PowerCenter environment variables is presented below:
INFA_HOME=/opt/Informatica/9.0.1
INFA_DOMAINS_FILE=$INFA_HOME/domains.infa
PM_ROOT=$INFA_HOME/server/infa_shared
PM_HOME=$PM_ROOT
PATH=$PATH:$INFA_HOME/server/bin
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$INFA_HOME:$INFA_HOME/server/bin
JRE_HOME=$INFA_HOME/Java
For each Integration Service make sure that $PMRootDir variable is set properly. Is should be set to path:
