Re: Error while starting service grid with persistent store enabled

Hi, 

I tried to reproduce the issue on 'master' and it seems it was resolved by
IGNITE-5843 & IGNITE-5075.

Thanks!

Re: Error while starting service grid with persistent store enabled

Hi, 
  When error occured I have used following deployment method,

cfg.setName("myService_rishi");
cfg.setService(new codeToDeploy());
cfg.setTotalCount(9);
cfg.setMaxPerNodeCount(1);
ignite.active(true);
ignite.services().deploy(cfg);

but then I changed deployment method to, 

ignite.active(true);
IgniteServices svcs = ignite.services();
svcs.deployNodeSingleton("TestService", new SurveillanceAlert());

Also initially code I wrote in java file and xml file, configuration was
differing. Later I corrected it.

Thanks,
Rishikesh

Hi Rishikesh,

Could you please create a reproducer project with config that fails with
NPE? This will help to find a bug.

Thanks!
-Dmitry.

Guys,

I see the NPE is the stack trace which suggest that this is a bug and not a 
misconfiguration:

Suppressed: java.lang.NullPointerException
at
org.apache.ignite.internal.processors.cache.persistence.GridCacheDatabaseSharedManager.getPageMemoryForCacheGroup(GridCacheDatabaseSharedManager.java:1451)
at
org.apache.ignite.internal.processors.cache.persistence.GridCacheDatabaseSharedManager.restoreMemory(GridCacheDatabaseSharedManager.java:1396)

Dmitriy, could you reproduce the issue? It should be easy to do this 
considering the place where NPE happened.

Hi,

The big slowdown gives writing WAL into disk. You may increase throughput by
setting lower fail safe requirements: set
PersistentStoreConfigiration.setWalMode() to LOG_ONLY (data may be lost on
power off) or BACKGROUND (data may be lost on process crash), or increase
available memory and set lower checkpoint frequency
PersistentStoreConfigiration.setCheckpointingFrequency(). 

Thanks!
-Dmitry.

Hi,
Setting same configuration in xml files and java code solved my problem.
Also one another question, what parameters can we tune when persistent store
enabled to get high throughput for data caching?

Thanks,
Rishikesh

Hi Rishikesh,

I cannot reproduce the issue.
Could you provide me with more details? Please share IgniteConfiguration
(xml or java code) and service which you are trying to deploy via Ignite
Service Grid.

Thanks.

What might be the issue?
