Tomcat 7
 

I have configured Tomcat 7 and there are many site which are hosted on same server. The issue is that when i restart the tomcat it took 19 mint to deploy all .war file as by default its using deployOnStartup="true".

I want to know if i make deployOnStartup="false" in server.xml will it give any issue for those site whose .war file is already extracted.

Well in my opinion and previous experience with Tomcat, it shouln't give you any issues with the other sites after changing that parameter to false but I'd like to suggest you to test it out on a test environment rather doing it on a production server.

In case of any issues, please paste the logs here!

Good Luck!!
