COULD NOT RESERVE ENOUGH SPACE FOR OBJECT HEAP

[manojdrana]

Hello,

I installed Jasper Server Community version on 32 Bit Windows xp server.  When i am trying to start service, its not starting. I checked the apache/logs.

 

I am seeing this error:

[2013-07-05 11:11:06] [info] Commons Daemon procrun finished.

[2013-07-05 11:13:15] [info] Commons Daemon procrun (1.0.2.0) started

I thought its 32 bit RAM size is creating the problem so i changed JAVA_OPTS values in js-export.bat, js-import.bat and in cataling.bat. I tried with the lowest -xms,-xms and -xx:MaxPermSize but still error is coming.

 

does any have have any idea about the solution? I really appreciate your help.

 

Thanks,

Manoj Rana

This is because tomcat is deployed as Windows service, and your java_opts can be overriden by service properties. Try something like this:

Take a look at this Topic: JasperReports Server Performance.

And, in particular: Hardware Requirements for JasperReports Server.

It maybe your RAM is not enought to creat JVM. So you need to set your java memory in tomcats smallers.

Open command line, cd C:Jaspersoftjasperreports-server-cp-5.6.0apache-tomcatbin

Goto C:Jaspersoftjasperreports-server-cp-5.6.0apache-tomcatbin

 

you can see tomcat7w or tomcat6w (depend on your Tomcat version).

In command line (see in below picture)

jasperreportstomcat propertise show up,

in java tab, Java Options, you will see

-Xms1024M
-Xmx2045M
-Xss2M
-Dcatalina.base=C:JASPER~1JASPER~1.0APACHE~1
-Dcatalina.home=C:JASPER~1JASPER~1.0APACHE~1
-Djava.endorsed.dirs=C:JASPER~1JASPER~1.0APACHE~1endorsed
-XX:PermSize=128m
-XX:MaxPermSize=256m
-XX:+UseConcMarkSweepGC
-XX:+CMSClassUnloadingEnabled
 

Adjust -Xms1024M and -Xmx2045M with smaller value (may be 512 and 1024) then apply.

After that goto services and restart jasperreportstomcat
