Symptoms

Using 12.1.0.5 agent with 12.1.0.8 Database Plugin.
Attempting to discover new databases on the target server using the below methods do not list any targets:

1. Auto discovery method.
2. Add target manually via guided process

- The 12.1.0.8.160930 agent-side Discovery <Patch 24610055> has been applied recently to the Database Plugin home at this agent.

- With DEBUG level logging, the <AGENT_INST>/sysman/log/gcagent.log shows the below entries:

2016-10-11 14:58:34,018 [1033:FD98A2F4] DEBUG - pluginId=oracle.sysman.db,scriptName=discover/oracledb.pl

The oracledb.pl script is getting called at 2016-10-11 14:58:34. However, the emagent_perl.trc shows no entries for the oracledb.pl script when the Database discovery is run, even when the DEBUG level tracing is enabled for PERL modules. 

-  Attempting to execute the <AGENT_BASE_DIR>/plugins/oracle.sysman.db.discovery.plugin_12.1.0.8.0/discover/oracledb.pl script manually fails with:

$ perl oracledb.pl '<HOSTNAME>'
Global symbol "$hostMatchFound" requires explicit package name at oracledb.pl
line 1500.
Execution of oracledb.pl aborted due to compilation errors.
