h1. Question: The installation for caArray installation or upgrade failed. Where can I find the error log?

*Topic*: caArray Installation and Upgrade

*Release*: caArray 2.X

*Date entered*: 07/27/2010

h2. Answer

Two JBoss servers that make up caArray, and the JBoss server optionally installed for UPT, run continually as services. 

* JBoss 4.0.5 for UPT (optional)
* JBoss 4.0.4 (for caArray Grid services)
* JBoss 4.0.5 (for caArray application)

The daily activity for each server is recorded in the server.log file, located in $JBOSS_HOME\server\default\log directory. The previous day's log files are automatically archived and renamed as: server.log.YYYY-MM-DD, stored under the same directory.
