After DLP DB install, start database if necessary

Was getting errors when verifying the Symantec Data Loss Prevention database. When I would type the command $ORACLE_HOME/bin/lsnrctl services LISTENER I would get The listener supports no services

This can happen if for some reason the database has not started.

Try starting the database:

$ sqlplus '/ as sysdba'
Then, enter
startup at the SQL prompt.

Once the database has started, verification succeeds!

See http://www.thegeekstuff.com/2009/01/oracle-database-startup-and-shutdown-procedure/

Notes:

If you get "TNS-12541: TNS:no listener" when running the first command above, try doing: $ORACLE_HOME/bin/lsnrctl start :)
After that, you may need to restart the Vontu services. Then you should be able to login to https://vontuIP/ or https://vontuIP:8443

Here's a quick script to restart the services on the Enforce server. Add VontuMonitor.sh if single-tier:
cd /opt/Vontu/Protect/bin

./VontuUpdate.sh stop
./VontuIncidentPersister.sh stop
./VontuManager.sh stop
./VontuMonitorController.sh stop
./VontuNotifier.sh stop
./VontuNotifier.sh start
./VontuManager.sh start
./VontuIncidentPersister.sh start
./VontuUpdate.sh start
./VontuMonitorController.sh start



Three-tier DLP Installation - The Oracle Client

There is little in the way of documentation for this.

So, I unwrapped Oracle_11.2.0.1.0_64bit_Client_Lin. Start reading the docs, i.e., the Client Quick Installation Guide. Followed all the instructions in there, including creating the oracle account, etc. For user oracle creation, running oracle_prepare.sh from 11g_r2_32_bit_Installation_Tools.tar.gz works.

Then in order to get past the DLP installation wizard's Oracle page, i.e. error "sqlplus is not executable at /opt/oracle/product/11.2.0/db_1/bin", I needed to do the following for the root account:

If you did not install the Oracle client to /opt/oracle/product/11.2.0/db_1/ then perform the following.
Add the following lines to the root .bash_profile:
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/client_1
LD_LIBRARY_PATH=$ORACLE_HOME:/lib:/usr/lib
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH

PATH=$PATH:$HOME/bin:$ORACLE_HOME

Then,
. ~/.bash_profile to set the environment.
Then,
mkdir $ORACLE_HOME/bin
cd $ORACLE_HOME/bin
ln -s ../sqlplus
mkdir $ORACLE_HOME/lib


Copy all *.so, and so.11.1 files to $ORACLE_HOME/lib
I also created $ORACLE_HOME/jdbc/lib and to it copied ojdbc*.jar from $ORACLE_HOME.

Be sure to:

set the Base directory and Home directory to match the ORACLE_HOME and ORACLE_BASE paths above in the installation wizard of DLP.
