A simple, minimalistic environment is the best approach.
Example:ORACLE_HOME=/u01/app/oracle/product/12.2.0.1/db_1;export ORACLE_HOME
INFA_HOME=/opt/informatica/10.2.0/PowerCenter;export INFA_HOME
INFA_DOMAINS_FILE=/opt/informatica/10.2.0/domains.infa;export INFA_DOMAINS_FILE
LD_LIBRARY_PATH=$ORACLE_HOME/lib:$INFA_HOME/server/bin::$LD_LIBRARY_PATH;export LD_LIBRARY_PATH
Result:SQL DB Service
