Thanks to Zenoss Community member Roman Tykhonov for submitting his new Oracle Database ZenPack.  This very thorough ZenPack monitors Oracle databases with sqlplus and tnsping  (which  need to be installed before use).  It provides 3 templates (under  /Devices/Server)  ORACLE_INSTANCE, ORACLE_INSTANCE_ADDITIONAL and TNS_TEST with a total of 19 graphs.  If you're using Oracle, take a good look at this ZenPack.

Thanks Roman!
