Installing Infrastructure Tier
The installation of AS10g should be done in specific order only as explained before. This is because of the dependencies between the components. Here we are going to install Portal and Wireless option of mid tier, this needs database repository for storing the information of these components. So we will first install infrastructure tier and then install Mid tier. Please follow the below screen shots.

Oracle Application server 10g unable to start HTTP

Posted on by Osama Mustafa in Application
Hi all

Today When I was Supporting for some customer , i faces issue in application server 10gthe solution is so simple


Let describe the problem :


when we use

./opmnctl startall


all service is up expect Http_server is down

Check Logs nothing , Check Application server logs nothing

And when you try to shutdown IAS again it will give you :

RCV : Permission denied

For first i was thought its permission issue but who can change the permission .




the solution like the following :


On Os


ps -ef | grep oracle


you must find 2 process
Oracle PID $PATH/opmn.d


kill them both
Kill PID PID
or
Kill -9 PID
kill -9 PID


After this
./opmnctl startall
