ignite service session issue

Hi there, I am running the ignite service via ssh terminal. I use command like this : ./ignite.sh �CJ-Xms8g �CJ-Xmx8g & However, when I turn off the terminal, the ignite server is also closed. Is there anyway to make sure the service running without depend on terminal session? Cheers, Kevin [l

If adding ignite-log4j module slows you down, then you're definitely producing too much logs. Can you double check your settings? -Vla -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/ignite-logging-not-captured-in-log-file-log4j-tp4334p4474.html Sent from the A

Detecting a node leaving the cluster

I have an application that is using Ignite for a clustered cache. Each member of the cache will have connections open with a third party application. When a cluster member stops its connections must be re-established on other cluster members. I can do this manually if I have a way of detectin

Re: At client side unable to use excute transaction?

Val, StringBuilder.append() is what javac generates for `"Read value: " + val` in the code. Ravi, Hibernate returned you a collection proxy for your map, however by the time control flow leaves the CacheStore your hibernate session gets closed and this collection proxy cannot be used anymore. Yo

Re: Client fails to connect - joinTimeout vs networkTimeout

Binti, It sounds like client were not able to connect due to instability on the server, and increasing networkTimeout gave them a better chance to join, but most likely they could not work properly anyway. Is I said, most likely this was caused by memory issues. Any particular reason you're start

Re: ignite logging not captured in log file (log4j)

Hi Binti, Did you set DEBUG level of org.apache.ignite? If so, this will produce too much output and will definitely slow you down. You should use DEBUG only if it's needed, and preferably for several particular categories you need DEBUG output for. -Val -- View this message in context: http:

Re: Performance Issue - Threads blocking

Hi Matt, I'm confused. The locking does happen on per-entry level, otherwise it's impossible to guarantee data consistency. Two concurrent updates or reads for the same key will wait for each other on this lock. But this should not cause performance degradation, unless you have very few keys and v

Re: What will happend in case of run out of memory ?

Hi, Data will be persisted unless the cache update fails on the server (in this case you will get an exception on client side). To avoid out of memory issues, you can use evictions [1], that will remove less frequently used entries from memory. If you need an evicted entry again, it will loaded fr

Re: ignite logging not captured in log file (log4j)

Val, adding the dependency worked. The clients also started logging at root level. We will have to modify the client log4j files to only log Error level. Thanks, but we saw another issue now. When we tried to bring up the grid (server nodes - ERROR level) and if old clients were already connected,

Re: Client fails to connect - joinTimeout vs networkTimeout

2. I see your point, but setting joinTimeout looks like a good solution. Does it work for you? joinTimeout was working earlier with 5 seconds, for some clients we had to raise it. but eventually some clients could not connect at all with any jointimeout. We had to remove joinTimeout and add networ

Re: Error running nodes in .net and c++

Re: Performance Issue - Threads blocking

I'm assuming you're seeing a lot of threads that are BLOCKED waiting on that locked GridLocalCacheEntry (<70d32489> in that example you pasted above). Looking at the code, it looks like it does block on individual cache entries (so two reads of the same key within the same JVM will block). In your
