    <p>I'm having trouble with a web service deployed on Tomcat. During peak traffic times the server is becoming non response and forces me to restart the entire server in order to get it working again.</p> <p>First of all, I'm pretty new to all this. I built the server myself using various guides and blogs. Everything has been working great, but due to the larger load of traffic, I'm now getting out of my league a little. So, I need clear instructions on what to do or to be pointed towards exactly what I need to read up on.</p> <p>I'm currently monitoring the service using JavaMelody, so I can see the spikes occurring, but I am unaware how to get more detailed information than this as to possible causes/solutions.</p> <p>The server itself is quad core with 16gb ram, so the issue doesn't lie there, more likely in the fact I need to properly configure Tomcat to be able to use this (or setup a cluster...?) </p> <p>JavaMelody shows the service crashing when the cpu usage only gets to about 20%, and about 300 hits a minute. Is there any max connection limits of memory settings that I should be configuring?</p> <p>I also only have a single instance of the service deployed. I understand I can simply rename the war file and Tomcat deploys a second instance. Will doing this help?</p> <p>Each request also opens (and immediately closes) a connection to mySQL to retrieve data, I probably need to be sure it's not getting throttled there too.</p> <p>Sorry this is so long winded and has multiple questions. I can give more information as needed, I am just not certain what needs to be given at this time!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
