How to correctly monitor a Database Oracle
we are configuring a monitor health for a Oracle database which has the next configuration parameters: Send String: select * from dual Response: X user:CONSULTA_ANALISTA password:xxxxxxx connection string: PRODM1 = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = %node_ip%)(PORT = %node_port%)) ) (CONNECT_DATA = (SID = PRODM1) ) ) Row:3 Column:1 alias address:172.20.1.73 alias service port:1527 the monitor doesn't work and the pool member never is seen up, i have looked at the debug of the connection and this is what i see in a portion of it: [root@ltm1:Active:Changes Pending] monitors tail -30 Common_BD_monitor_PDN-Common_BD-1527.log DATABASE=PRODM1 = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = %node_ip%)(PORT = %node_port%)) ) (CONNECT_DATA = (SID = PRODM1) ) ) DEBUG=yes MON_INST_LOG_NAME=/var/log/monitors/Common_BD_monitor_PDN-Common_BD-1527.log MON_TMPL_NAME=/Common/BD_monitor_PDN NODE_IP=::ffff:172.20.1.73 NODE_PORT=1527 PASSWORD=nc5gf56y RECVCOLUMN=1 RECVROW=3 RECV_I=X SEND=select * from dual USERNAME=CONSULTA_ANALISTA TMOS_RD: 0 (0) Daemon port: 1521 count='0' converts to '0' Command-line PID filename: /var/run/ORACLE__Common_BD_monitor_PDN_::ffff:172.20. 1.73-0_1527.pid PID file /var/run/DBDaemon-0.pid exists. Checking for correctness of PID. DBDaemon on port 1521 says its PID is 19578. PID matches EXCEPTION connecting to DBDaemon: fflush(): Connection reset by peer i have also tried putting all the info directly like this: ********** Debugging session beginning at: Mon Jul 6 17:07:02 2015 Arguments 1-2: ::ffff:172.20.1.73 1527 Environment variables: COUNT=0 DATABASE=PRODM1 = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 172.20.1.73)(PORT = 1527)) ) (CONNECT_DATA = (SID = PRODM1) ) ) DEBUG=yes MON_INST_LOG_NAME=/var/log/monitors/Common_BD_monitor_PDN-Common_BD-1527.log MON_TMPL_NAME=/Common/BD_monitor_PDN NODE_IP=::ffff:172.20.1.73 NODE_PORT=1527 PASSWORD=nc5gf56y RECVCOLUMN=1 RECVROW=1 RECV_I=ok SEND=TNSPING 172.20.1.73 1527 USERNAME=CONSULTA_ANALISTA TMOS_RD: 0 (0) Daemon port: 1521 count='0' converts to '0' Command-line PID filename: /var/run/ORACLE__Common_BD_monitor_PDN_::ffff:172.20.1.73-0_1527.pid PID file /var/run/DBDaemon-0.pid exists. Checking for correctness of PID. DBDaemon on port 1521 says its PID is 19578. PID matches Asking daemon to ping remote database. Expected result not received: Database down, see /var/log/DBDaemon.log for details. Database down, see /var/log/DBDaemon.log for details. If i look into /var/log/DBDaemon.log; it isn't updating. It seems that somehow the process is attached to other monitor over port 1521 an maybe that is the origin of the conflicto and fail of Oracle monitoring: [root@ltm1:Active:Changes Pending] monitors ps -fe|grep DB root 19578 1 0 Jun16 ?
