    ARC "unable to execute reports" error

    When trying to run reports in ARC, we are getting "unable to execute reports" error.

    We can't login into ARC at all.

    Please follow ARC troubleshooting instructions outlined below. Submit a Pivotal incident if the problem is not resolved after you've restarted the CRN in step 4.

    The following components should be up:

    1. Oracle database and Listener
    2. iPlanet (Sun ONE)
    3. Apache
    4. CRN – must be checked and started/restarted last

    1. Oracle instance and Listener

    sqlplus $ARCCONNSTR@$ARC_SID
    Make sure you can connect to the database using the listener
    If it doesn’t work perform the following to check what is up:
    ps –ef | grep ora
    To start the listener (should be performed as oracle user):
    lsnrctl start
    To start the database (should be performed as oracle user):
    sqlplus /nolog
    connect / as sysdba
    set pause off

    2. iPlanet

    /usr/iplanet/servers/slapd-arc/check-slapd && echo "OK"
    If the iPlanet is up you will get: OK
    You can also check if you can connect to port 390 on localhost:
    telnet localhost 390
    If you need to start iPlanet you should do it as root user:
    Stopping the iPlanet server is not required and not recommended unless the machine is going down

    3. Apache

    To check if the apache is up:
    ps –ef | grep http | grep crn
    To start/stop the apache server:
    cd ~crn/apache/bin
    ./apachectl stop
    ./apachectl start
    If the Apache port is less then 1024 start and stop must be done as root user with full path.

    4. CRN – must be checked and started/restarted last

    Make sure all other components are up
    Check which CRN processes are running:
    you will get a list of running process excluding httpd
    Check that the service is working properly:
    cd ~/cognos/bin
    ./ isRunning
    you should get:
    ReportNet service is running
    To start and stop the crn
    cd ~/cognos/bin
    ./ <start/stop>
