Re: Cannot access Dspace -Urgent help

[Tom Obrien]

Hi all,

I installed Dspace 6.4 on Ubuntu 22. I has been accessible until yesterday when i started receiving error in the browser:

Service Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Apache/2.4.52 (Ubuntu) Server at x.x.x.x Port 80

I need urgent help to resolve this issue. Kindly assist.

Regards

Tom

Hi Tom

Have you checked if tomcat is running?

I am assuming your setup includes tomcat, Apache2 and some connector handling the communication between the two (2).

To check on tomcat, try the following on the prompt.

#ps -e|grep java

Or 

#netstat -tlpn|grep java

Regards

Hi Bravismore,

When I ran the two commands I get the following:

#ps -e|grep java

    400 ?        02:12:06 java

#netstat -tlpn|grep java
tcp6       0      0 127.0.0.1:8005          :::*                    LISTEN      400/java            
tcp6       0      0 127.0.0.1:8009          :::*                    LISTEN      400/java

Hi Tom

The next step would be to check how you are connecting the two(2); tomcat and Apache.

The port that connector (or proxy) is using.

You need to consult the server.xml config file for tomcat.

Also check path to your web apps (whether you have published them)

Or try restarting the two deamons (tomacat and Apache). Not sure if order matters but tomacat should be available for Apache to request pages.

Also check postgres is running

Regards

Thank you very much. I restarted the postgres and it worked.

very grateful

[Mumanyi, Bravismore]

Great stuff.

You may want to zero in on why it stopped.

Perhaps add more memory, connection pool - optimization

Regards
