Build failure
Jempan opened this issue · 4 comments
Started to get inconsistency exceptions yesterday from my Neo4j 2.2.3 production database yesterday :( Used this tool successfully 2 years ago to repair another database in another project but now I cannot get it to work. I am on Windows and I have set the environment variable MAVEN_OPTS according to copy-store.sh and run the command:
mvn compile exec:java -e -Dexec.mainClass="org.neo4j.tool.StoreCopy" -Ddbms.pagecache.memory=2G -Dexec.args="C:/Users/Jenny/Desktop/backup C:/Users/Jenny/Desktop/new_store"

How big is your store?
Can you try to run it with MAVEN_OPTS="-Xmx4G" mvn ...
The store is 179 MB. Cmd didn't like setting MAVEN_OPTS but it accepted mvn -DargLine="-Xmx4G".. which unfortunately fails with the same exception.
I don't think it does the same as it doesn't for a new by default and argLine are regular arguments too.
set MAVEN_OPTS="-Xmx4G"
echo %MAVEN_OPTS%
you can test it by setting it to -version then any maven command should just output the java version and exit.
I finally after some trial and error got it to work with MAVEN_OPTS set to -Xms1G. Thanks for your help Michael!
