If you are getting 404 error like below while opening admin console URL then you should check for broken admin console. This issue can happen if some files related to admin console got deleted from server or tomcat installation is corrupted due to some other reason on server.
HTTP Status 404 - /administrator/ type Status report message /administrator/ description The requested resource is not available.
It is important to ascertain that the error you are getting is indeed due to broken admin console and not some other issue with Informatica Domain.
In case of broken admin console you would find that tomcat web server is running on the informatica server but admin console is not opening in browser or throwing 404.
How to check Informatica Admin Console is running on tomcat
You can check for the connectivity of tomcat with an admin console from the server using netstat. If tomcat is running then you would see listening connection on the port on which admin console is running .
By default it should be port 7000. Find out the Informatica process id and check output of following
netstat -tulpn | grep (informatica-pid)
netstat -tulpn | grep 5889
tcp6 0 0 :::7000 :::* LISTEN 5889/java
You can also grep netstat output for an admin console port to get connectivity status.netstat -tulpn | grep (port-number)
netstat -tulpn | grep 7000
tcp6 0 0 :::7000 :::* LISTEN 5889/java
Solution : In the next post we will will learn how we can resolve this issue by building an Informatica Admin Console from scratch.
