I have installed Zabbix server with "--unix-odbc" option.
I have installed the client for Oracle 10.2 databases with odbc, basic and sqlplus from https://www.oracle.com/technetwork/database/enterprise-edition/downloads/linuxx86-64soft-092277.html
I have configured the enviroment variables on /etc/environment and systemd zabbix service (see zabbix-server.service).
The file /etc/odbcinst.ini has the path to Oracle's driver (see odbcinst.ini).
With Zabbix user, if i execute "isql" it connects to database:
But on Zabbix, item of type "Database monitoring" with odbc does not work.
Everytime it's checked Zabbix shows a backtrace on the log (see zabbix_server.log). Zabbix server process does not stops after crash, it keeps running normally.
