 +====Check process connections====
 +We can check if a process is making connection from outside as follows:
 +
 +<Code:bash|Check process connections>
 +[root@ag-se-tlcasdb1 ~]#  lsof -i -a -p 4970
 +COMMAND  PID   USER   FD   TYPE   DEVICE SIZE/OFF NODE NAME
 +oracle  4970 oracle   16u  IPv6 37827976      0t0  TCP ag-se-tlcasdb1.net.tain.com:ncube-lm->172.25.2.12:43612 (ESTABLISHED)
 +</Code>
 +
 +As we can see, that is very useful for oracle processes. When the connection HAS to create process also ON the local server.
