OHS: Find Version

If you have registered Oracle HTTP Server (OHS) with Domain, you can easily find the version through EM console.

Following steps will help you, if you want to find it through CLI.

Steps:

1. Check ORACLE_HOME and LD_LIBRARY_PATH environment variables.
    echo $ORACLE_HOME
    echo $LD_LIBRARY_PATH
2. If environment variables not set, set as below
    export ORACLE_HOME=<Directory where OHS is installed> 
    Ex:  export ORACLE_HOME=<FMW_HOME>/ohs_111

For 10g & 11g: Includes OPMN lib directory
    export  LD_LIBRARY_PATH=$ORACLE_HOME/ohs/lib:$ORACLE_HOME/opmn/lib:$ORACLE_HOME/lib:$LD_LIBRARY_PATH

For 12c:
    export LD_LIBRARY_PATH=$ORACLE_HOME/ohs/lib:$ORACLE_HOME/lib:$LD_LIBRARY_PATH

3. Go to ORACLE_HOME/ohs/bin directory
    cd $ORACLE_HOME/ohs/bin
    Ex: cd <FMW_HOME>/ohs_111/ohs/bin

4. Execute below command to get OHS version
    ./httpd.worker -version

Sample Output:
