How to find what process is using a port in AIX

This is a copy/paste from different posts on IBM forums.

1. Add the -A argument to the "netstat" command and then use that output as an argument to the rmsock command to find the PID of the process using the port.

oracle@oraforms1> netstat -Aan|grep 7778
f1000e0000aa13b8 tcp        0      0  *.7778                *.*                   LISTEN

2. Execute command "rmsock" to remove a socket that does not have a file descriptor.

oracle@oraforms1> rmsock f1000e0000aa13b8 tcpcb
The socket 0xf1000e0000aa1008 is being held by proccess 4718790 (httpd.worker).

3. Execute "ps" for looking after PID.

oracle@oraforms1> ps -ef|grep 4718790

oracle  4718790  9044154   0 08:33:36      -  0:00 /u01/oracle/MWohs/Oracle_WT1/ohs/bin/ httpd.worker -DSSL
