<![CDATA[Initialization of subagent "ORACLE" failed]]>Hi, we have installed agent on Linux and trying to add subagent Oracle.

Core agent version 4.3-243-g93e41d8

config:

SubAgent=/opt/netxms/lib/netxms/oracle.nsm
DBDriver=/opt/netxms/lib/netxms/dbdrv/oracle.ddr

During startup, agent rising error:

Please advice.

Also i've added ORACLE_HOME and LD_LIBRARY_PATH into agent config file.
It was read by agent and written in log.
But driver initialization failed and there is no other errors or messages even in debug 9.

That is why i've started this topic.

For the agent config, you can specify env variables in [env] section, e.g.

[env]
ORACLE_HOME=/uat/db/19c
LD_LIBRARY_PATH=/uat/db/19c/lib

but I am not sure, if this affects database drivers, or only processes that agent launches after it has started (e.g. external metrics).

I've added into agent config file

ORACLE_HOME=/uat/db/19c
LD_LIBRARY_PATH=/uat/db/19c/lib

Also
ldd oracle.ddr |grep 19

libclntshcore.so.19.1 => /uat/db/19c/lib/libclntshcore.so.19.1 (0x00007f75e4403000)

So i guess all libs should be available
