Dear team,
I'm trying to install dspace 5.1 on Ubuntu server LTS 14.4.01 64bit.
I used apt-get command to install OpenJDK 7, Tomcat, postgresql, mvn, ant.
The version of OpenJDK and Tomcat: OpenJDK 7u75, Tomcat 7.0.52.0
My problem is: I always got problem when deploying rest.
Caused by: java.lang.OutOfMemoryError: Java heap space
at java.util.Arrays.copyOf(Arrays.java:2271)
at
java.io.ByteArrayOutputStream.grow(ByteArrayOutputStream.java:113)

java.io.ByteArrayOutputStream.ensureCapacity(ByteArrayOutputStream.java:93)

at java.util.jar.JarInputStream.<init>(JarInputStream.java:86)
at java.util.jar.JarInputStream.<init>(JarInputStream.java:62)
If I remove rest from webappst, everything was ok. I can access web
interface, login and perform all administration tasks (there is only 1 issue
in jspui: The recently added item doesn't appear)
I did some research and found that: This problem happens when the server
doesn't have enough memory (describer in parameter: Xmx) for Tomcat to
deploy 1 application. But my server is 8Gb of memory and I tried many ways
to setup Tomcat option to increase Xms, Xmx, MaxPermSize.. Below are some
commands that I tested:
Export TOMCAT_OPTS="-Xms6144M -Xmx6144M -XX:MaxPermSize=512M"
Export JAVA_OPTS="-Xms6144M -Xmx6144M -XX:MaxPermSize=512M"
export CATALINA_OPTS="-Xms6144M -Xmx6144M -XX:MaxPermSize=512M"
I don't know why REST application requires so much memory like that and I
really want to know how much memory is enough for REST. From the wiki, high
end dspace system only requires 8Gb:
