Problem indexing a class

[craigching]

I'm getting the following warning in my logs when I put an object into a cache that has indexing turned on:

{quote}31 Mar 2011 13:15:50,310 WARN:Component Resolve Thread:TransactionalWorker> It appears changes are being pushed to the index out of a transaction. Register the IndexWorkFlushEventListener listener on flush to correctly manage Collections!{quote}

What do I need to do to ensure that Hibernate search has a transaction?

I naively added the following to my cache configuration:

{code:xml}    <transaction  
      transactionManagerLookupClass="org.infinispan.transaction.lookup.GenericTransactionManagerLookup"
      syncRollbackPhase="false"
      syncCommitPhase="false"
      useEagerLocking="false"/>{code}

And used getAdvancedCache().getTransactionManager() to surround my put() with begin() and commit(), but that didn't help and I have to admit I really don't know much about what needs to be done.

Hi,

When you ran the transaction code, did you get java.lang.IllegalStateException: Illegal
attempt to enlist a 2PC XAResource?

We have the same transaction configuration but I can't run the transaction code. See

http://community.jboss.org/message/596932#596932Transaction exception: Illegal attempt to enlist a 2PC XAResource. Do you have any advice about it?

Thanks.

I have the same problem. For each entry that I put into infinispan cache, I got:

[org.hibernate.search.backend.impl.TransactionalWorker] It appears changes are being pushed to the index out of a transaction. Register the IndexWorkFlushEventListener listener on flush to correctly manage Collections!

Here is my cache config:

<infinispan-config name="epen_application" jndi-name="java:CacheManager/epen">

        <infinispan xmlns="urn:infinispan:config:5.0">

            <global>

                <transport clusterName="${jboss.partition.name:DefaultPartition}-epen"

                    distributedSyncTimeout="17500">

                    <properties>

                        <property name="stack" value="${jboss.default.jgroups.stack:udp}" />

                    </properties>

                </transport>

                    <l1 enabled="false" lifespan="60000" />

                    <hash numOwners="1" rehashRpcTimeout="120000" />

                    <async />

                </clustering>

            </default>

            <namedCache name="response_record">

                <indexing enabled="true" indexLocalOnly="true">

                <properties>

                    <property name="hibernate.search.default.directory_provider" value="ram" />                   

                </properties>

                </indexing>

                <eviction maxEntries="100000" />

                <expiration lifespan="600000" />

            </namedCache>

        </infinispan>

    </infinispan-config>

Does this warning mean that adding index for this entry failed or it is just a warning? How to get around it?

Thanks.

Also, with the index set as "ram", I sometimes got this error when I add a entry into cache:

Thanks.

It's just a warning, and in fact it applies only when this engine is used to index entities managed by Hibernate: the warning should not apply to Infinispan and I'm going to remove it from being logged. For now ignore it, thanks.

I've opened https://issues.jboss.org/browse/ISPN-1218 to track this.
