Re: Upgrading Solrcloud indexes from 7.2 to 8.4.1

When you say “reindexed”, how exactly was that done? Because if you didn’t start from an empty index, you will have to re-index from scratch to use 8x. Starting with 6.x, a marker is written whenever a segment is created indicating what version was used. Whenever two or more segments are

Re: Upgrading Solrcloud indexes from 7.2 to 8.4.1

You best off doing a full reindex to a single solr cloud 8.x node and then when done start taking down 7.x nodes, upgrade them to 8.x and add them to the new cluster. upgrading indexes has so many potential issues, > On Mar 6, 2020, at 9:21 PM, lstusr 5u93n4 wrote: > > Hi Webster, > > When

Re: Upgrading Solrcloud indexes from 7.2 to 8.4.1

Hi Webster, When we upgraded from 7.5 to 8.1 we ran into a very strange issue: https://lucene.472066.n3.nabble.com/Stored-field-values-don-t-update-after-7-gt-8-upgrade-td4442934.html We ended up having to do a full re-index to solve this issue, but if you're going to do this upgrade I would

Upgrading Solrcloud indexes from 7.2 to 8.4.1

We are looking at upgrading our Solrcoud instances from 7.2 to the most recent version of solr 8.4.1 at this time. The last time we upgraded a major solr release we were able to upgrade the index files to the newer version, this prevented us from having an outage. Subsequently we've reindexed

Re: OutOfMemory error solr 8.4.1

I assume you recompiled the jar file? re-using the same one compiled against 5x is unsupported, nobody will be able to help until you recompile. Once you’ve done that, if you still have the problem you need to take a thread dump to see if your custom code is leaking threads, that’s my number

Re: OutOfMemory error solr 8.4.1

Hi Erick, We have custom code which are schedulers to run delta imports on our cores and I have added that custom code as a jar and I have placed it on server/solr-webapp/WEB-INF/lib. Basically we are fetching the JNDI datasource configured in the jetty.xml(Oracle) and creating connection

Re: OutOfMemory error solr 8.4.1

This one can be a bit tricky. You’re not running out of overall memory, but you are running out of memory to allocate stacks. Which implies that, for some reason, you are creating a zillion threads. Do you have any custom code? You can take a thread dump and see what your threads are doing, and

Re: Problem with Solr 7.7.2 after OOM

Is it still giving you OOMs? That was the original problem statement. If not, then you need to look at your Solr logs to see what error is reported. NOTE: If you’re still getting OOMs, then there won’t be anything obvious in the logs. Best, Erick > On Mar 6, 2020, at 06:44, Bunde Torsten

OutOfMemory error solr 8.4.1

Hi All, I have recently upgraded solr to 8.4.1 and have installed solr as service in linux machine. Once I start my service, it will be up for 15-18hours and suddenly stops without us shutting down. In solr.log I found below error. Can somebody guide me what values should I be increasing in
