Re: [Fedora-commons-users] oaiprovider - fedora/risearch - out ofmemory error

[Steve Bayliss]

Hi Eric

What version of Fedora are you using? I ask as in version 3.3 we upgraded
to Mulgara 2.1.4; in the previous version of Fedora/Mulgara there were
reports of some query issues particularly related to before/after dateTime
constraints using the #xsd model.

Regards
Steve

Hi,

I recently made ~1100 objects in my fedora repository visible to the oaiprovider webapp by adding an itemID to these objects RELS-EXT. I successfully tested this with 2 objects individually. But after making the batch change, the oaiprovider failed with a java.lang.OutOfMemoryError.

The route cause of the OutOfMemoryError is a fedora risearch, particularly the query:


select $item $itemID $date $state

from <#ri>

where $item <http://www.openarchives.org/OAI/2.0/itemID> $itemID

and $item <info:fedora/fedora-system:def/model#state> $state

and $item <info:fedora/fedora-system:def/view#disseminates> $diss

and $diss <info:fedora/fedora-system:def/view#disseminationType> <info:fedora/*/DC>

Thanks Steve.

We are using fedora3.2. In trying to avoid an upgrade, is it possible to plug in Mulgara 2.1.4?

I see in fedora.fcfg:

<module role="fedora.server.resourceIndex.ResourceIndex" class="fedora.server.resourceIndex.ResourceIndexModule">
...
<param name="datastore" value="localMulgaraTriplestore">

and

<datastore id="localMulgaraTriplestore">
...
<param name="connectorClassName" value="org.trippi.impl.mulgara.MulgaraConnector">

Eric

[Steve Bayliss]

Hi James

Theoretically you could replace the mulgara and trippi jars with those in
the 3.3 release, but there might be some other dependencies as well, so I'm
not sure if this would work.

You could consider setting up a stand-alone instance of Mulgara 2.1.4
(download from http://www.mulgara.org/files/v2.1.4/mulgara-2.1.4-bin.tar.gz)
and then:

1) export your current triples from Fedora with something like:

wget -O all-rdf.xml
http://fedoraAdmin:fedoraAdmin@localhost:8080/fedora/risearch?type=triples\&
lang=spo\&format=RDF%2FXML\&stream=on\&query=*+*+*

or:

curl -o all-rdf.xml
http://fedoraAdmin:fedoraAdmin@localhost:8080/fedora/risearch?type=triples\&
lang=spo\&format=RDF%2FXML\&stream=on\&query=*+*+*

2) Load this file into Mulgara 2.1.4 (use the web interface at eg
http://localhost:8080/webui/) - note that if you've got Fedora running at
the same time you'll have to start Mulgara on a different port to 8080 -
check the Mulgara docs on how to do this here
http://www.mulgara.org/trac/wiki/StartStop

3) Run the same queries, and see if you encounter any memory problems (you
can experiment with the JVM memory settings)

At least this might indicate if it's worthwhile upgrading to Fedora 3.3 (or
attempting to update the mulgara/trippi jars plus any dependencies).

Another alternative would be to configure Fedora to use an external Mulgara
triplestore - see the instructions here -
http://www.fedora-commons.org/confluence/display/FCR30/Resource+Index#Resour
ceIndex-RemoteMulgaraDatastoreConfiguration - but in this instance you
should use the same Mulgara version as per the Fedora 3.2 release: check the
mulgara jar files to determine what this is. With Mulgara running in a
separate JVM you at least have more control over Mulgara's memory.

Out of curiosity, what are the JVM memory settings you're currently using
for Fedora?

[James, Eric]

Steve,

Looks like I'm going to have to try a upgrade in some incarnation. While the risearch worked when starting with a fresh proai database as I said in an earlier email, the next time it polled and ran the risearch, the java.langOutOfMemoryError occured, fatally stopping tomcat.

To answer your question, here are the tomcat memory settings:
/app/jdk1.6.0_14/bin/java -Xms1560m -Xmx1560m -XX:PermSize=256m -XX:MaxPermSize=256m ...

So, as you said, it looks like there are 3 options:
1) upgrade to fedora-3.3
2) try a standalone mulgara and configure fedora to use it as per: http://www.fedora-commons.org/confluence/display/FCR30/Resource+Index#ResourceIndex-RemoteMulgaraDatastoreConfiguration
3) added mulgara and trippi jars to /lib and rebuild index - but this might end up a long search for other dependencies and could break other things

I'm likely to go with 2 first then 1, and try to avoid 3.

This is all assuming the outOfMemory error will be resolved with the new version of mulgara.

Thanks,

Eric

Hi Eric

That sounds like a reasonable approach - however if it is something fairly
fundamental about that version of Mulgara and date/time constraints, it's
possible that (2) won't help much (as you'd be on the same version of
Mulgara).

For your info, the related thread on this (albeit to do with performance
rather than memory, but this could still be related as the query's pretty
much the same - and a good argument for upgrading in its own right) is:

Hi all,

we had the same problem as Eric but with Fedora 3.1, so we made an
upgrade to Fedora 3.3, and the things seemed ok. But after an ingestion
of some hundreds of objects we had a java.lang.OutOfMemoryError (see
first stack trace below). Restarting Tomcat we get always a new
java.lang.OutOfMemoryError (see second stack trace below). The only way
for not having 'out of memory' is disabling Proai polling
(proai.driverPollingEnabled = false) (proai.driverPollSeconds=600).
Memory java settings: -Xms512m -Xmx2048m.
Server version: Apache Tomcat/5.5.23
Server built: Jun 25 2009 12:44:09
Server number: 5.5.23.0
OS Name: Linux
OS Version: 2.6.18-194.el5PAE
Architecture: i386
JVM Version: 1.6.0_11-b03
JVM Vendor: Sun Microsystems Inc.

What else can we do?

This is the first out of memory stack trace (after ingestion):
