Server Startup time
Hi,
Our application uses JBoss application server. Recently we migrated from JDK 1.4 to JDK 5.0. When i start JBoss with 5.0 it take around 30 mins to start up, where as the same conf was around 8-10 mins with JDK 1.4. The OS is Windows 2000 server with 512MB RAM.
During testing when i used JBoss with 5.0 i did not face this problem. The machine on which i did testing were Windows 2003 and Windows 2000 Professional.
When i checked the supported configurations section from documentation it does not mention Windows 2000 server as supported OS where as Windows 2003 and Windows 2000 Professional are mentioned under this section.
Has anyone faced the same problem before? What could be possible reason for this?
Regards,
Sachin
Hi,
No error in boot.log. I am using following
-Djavax.xml.parsers.DocumentBuilderFactory=org.apache.crimson.jaxp.DocumentBuilderFactoryImpl
-Djavax.xml.parsers.SAXParserFactory=org.apache.crimson.jaxp.SAXParserFactoryImpl
-Djava.rmi.server.hostname=<ServerIP>
-server -Xms512m -Xmx512m
-Dsun.net.spi.nameservice.provider.1=dns,sun

1. I don't think is is drectly realted to the 1.5 upgrade; did you have any changes beside the 1.5 upgrade?
2. Can you see in the deploy logs who is the most "expensice" loader (time wise)
3. What is your memory usage (does it get near to 512M?)?
4. Do you use JBoss Clustering?
Hi,
If you see my original post, i have mentioined that start up time on the same machine with JDK 1.4 is 8-10 mins. I will have to check for the expensive thread, but how do i come to know this?
We are not using clustering. The memory usage is not reaching 512M atleast at the startup. One important point that i noticed is that on the server where i am facing problem the processor is X86 processor, which is supposed to be P3 type of processor. But on another machie with win2K and 512 MB RAM, which had P4 i did not face the problem.
Could it be something to do with the processor and not with OS ?
