Recently I installed JDK 6 on my CentOS instance. I noticed a weird service called jexec running on all run levels:
jexec 0:on 1:on 2:on 3:on 4:on 5:on 6:on
Googled and found this installation notes from Sun:
A new service script, named jexec, is added to /etc/init.d. This script allows users to directly execute any standalone JAR file that has an execution permission set.
OK, so it’s for executing jar files.. A tiny little bit more convenient than using java -jar, but no thanks, especially on a server.
One less thing to worry about: chkconfig –level 0123456 jexec off
Needed a VPS for one of my websites, so I’ve been doing some research on various hosts and plans. Here is what I found, as a side-by-side comparison matrix. From various sources, the hosting companies listed here generally seem to have good reputation:
||WiredTree (Virtuozzo, managed)
||LiquidWeb (Virtuozzo, managed)
My budget was around $20-$30 month, so I only listed the lower end plans of each host. Hopefully this can be helpful for someone who is looking for an entry-level VPS. Guess what host I chose at the end?
Update: I ended up choosing Linode. I narrowed down to slicehost & linode; both hosts look good and have good reviews at webhostingtalk. Slicehost’s website and management console are more appealing. But slicehost only provides 64 bit environment, which uses more memory than a 32-bit system. Here is a comparison. Also see this thread at slicehost forum: Might I have to say goodbye to Slicehost? (64-bit vs. 32-bit). Linode provides both 32-bit and 64-bit systems. Besides, linode provides more resources for the same 20 bucks (especially memory: 360MB vs 256MB); linode has data centers at four different locations to choose from while slicehost has only one. So far I’m a happy customer with Linode.
