What the heck is jexec?

April 2nd, 2009

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 :D

Choosing a VPS – side by side comparison

March 27th, 2009

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:

  Linode (XEN) RimuHosting (XEN) eApps (Virtuozzo) WiredTree (Virtuozzo, managed) LiquidWeb (Virtuozzo, managed) SliceHost (XEN)
Plan 360 VPS1 VPS2 standard standard plus standard max VPS384 VPS Basic 256 slice
Memory 360MB 160MB 400MB 160MB 288MB 432MB 384MB 384MB 256MB
Disk 12GB 4GB 4GB 2GB 4GB 6GB 40GB 20GB 10GB
Transfer 200GB 30GB 40GB 30GB 60GB 90GB 600GB 200GB 100GB
IP 1 1 2 1 1 1 4 4 1
Price $20 $20 $30 $10 $20 $30 $44 $60 $20

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.
