HTTP_Server Issue: Address already in use: make_sock: could not bind to address 127.0.0.1 port 7011

Hi today I faced some issue while restart the OAS HTTP_Server. Everything started fine except HTTP_Server.

Here, I would like to mention some steps to fix this issue.

In my case I had seen the following error when I executed. /opmnctl restartall

Work Around: We can find the error reason by using this log files. The Three logs are as follows:

1. Oracle_home/opmn/logs/opmn.log.

2. Oracle_home/opmn/logs/HTTP_Server~1.

3. Oracle_home/Apache/Apache/logs/error_log. (Open the latest one).

In my case there is error information in HTTP_Server~1 is as follow

This error will deceive us in hunting my workaround.

After I look into apache log file here I got a clue of the error. The error is

Address already in use: make_sock: could not bind to address 127.0.0.1 port 7011

Reason: The HTTP process running already on this port.

Solution:

1. Execute this command : ps -ef | grep httpd.

2. Kill all the process.

3. Start the http server as opmnctl startproc process-type=HTTP_Server.

Now the HTTP Server should start fine.

@ Venkat,
It is not possible for any two processes on same machine on same IP to use same port.

If you want two processes to use same port on same machine you must run them on different IPs (machine with two or more network cards).

If you have just one network card then change port on second instance to different value.
