I found out that my MySQL server is configured with only 128MB for innodb_buffer_pool_size. That is not enough considering that I have a 8GB RAM server. It hosts MySQL server and an Apache/Catalina server. What should I change this seeting to?

I have four(4) old posts to demonstrate how to measure and size up the InnoDB Buffer Pool based on the amount of RAM on the DB Server and how much space is currently being taken up by data/index pages:
Apr 14, 2011: What are the main differences between InnoDB and MyISAM?Oct 22, 2012: How much memory do I need for innodb buffer pool?Oct 22, 1012: How large should be mysql innodb_buffer_pool_size?Apr 08, 2013: MySQL performance impact of increasing innodb_buffer_pool_size
Please look over these posts, run the queries, and use good judgment. Why did I say to use good judgment ? If the ideal Buffer Pool Size is greater than 6GB (75% of your DB Server's RAM), the highest innodb_buffer_pool_size permissible would be 6G.
Give it a Try !!!

It is the default setting. You can modify it not higher than your memory can handle. Depends on the usage, set it to 70% of your memory might be good for a start.
