Re: Configuration Recommendations after ESX maintenance failure

Hi I want to make sure I am using correct vm ware terminology. They used vMotion and when this happend one of the ignite servers "moved" to another VMware host. Our network personnel tell me it should look like it is back "online" almost instantaneously. I thought we could solve this by increasing

Re: Missing records Ignite cache size grows

Yes, we checked uniqueness of key several times. Below is representative snippet of our code, how we generate cache key inside inputIterator method. @Override protected Iterator>> *inputIterator*(Object... args) throws CacheLoaderException {

Re: [RESOLVED] Cache Entries get lost after multiple nodes started ?

Neeraj, Rebalancing is not happening in this scenario. Any node stop/failure will cause data loss if there are no backups. Note that if you have a persistence store with read-through, you may live without backups, as any lost entry will be reloaded from the store when needed. -Val -- View

Re: Understanding Swap Space feature-- how it works?

Hi, Yes, swap space is transparent. Only keep in mind that whenever you read an entry from swap, it has to be unswapped first. So it's useful for the data that is rarely used, but still can't be accessed sometimes. If all you data is active, you will end up with a lot of swaps/unswaps which will

Hi Andrew, Problem is, we have 24 GB RAM, 8 CPU Windows server where we couldn't replicate the issue. Issue happens when we move it to Linux box with 64 CPU and set the memory 64 GB RAM (or higher) to process much larger volumes data, again we observed that Java collection gets populated correctly

Re: Node fauliure

Hi Anil, Partition processing time can be high due to non-uniform data distribution when data collocation or bad affinity function used. It is ok for collocate data, and it is shouldn't be an issue if partition size variation is low enough and you iterate over partitions in parallel manner.

Re: Node fauliure

Hi Andrey, if you notice in the log, time taken to process the partition is high ( > 15 sec). Not sure what is causing that high query time. In my case, both caches are collocated, and eqId column is indexed and setLocal is true for the query. I wonder if my approach is correct. please correct

[RESOLVED] Cache Entries get lost after multiple nodes started ?

I was able to resolve this. I set the backup copies of each cache to 1 in the XML file. Now, I can see all data present even if one goes down. But shouldn't data be automatically pushed/rebalanced to other nodes at the time of shutting down a node ? i.e. by the ignite-core capturing that event
