Out Of Memory error - Report generation of 3 lakhs records

What type of data is being retrieved here? Who is interested in such a long report ? Generally speaking, it is a rare requirement where users have to go through 300,000 records.
Is it a report or an online search screen?
If it is a report, why are you using servlet , session beans for reports? Why can't you use a reporting engine OR much better a DWH ?
If it is an online search screen, you need to add enough search filters to fetch small chunks of data. And if your filters still fetch so many records(which still is hard to make sense) ,
you should possibly do pagination (just Google for java pagination) and also limit the max. no. of search results to say 250 or 500 depending on the available amount of memory.

passing same jre options with different values

Would this work?

There are couple of other methods in the Runtime class:

freeMemory()
maxMemory()

You can do the math, I guess

FMC33146E DB2 API call 'sqlecrea' ended with error: 'SQL0083C A memory allocation error has occurred'.

Please let me know if anyone encountered this error earlier.

I referred to the IBM information center and it just gives me this information which doesnt work still.

Explanation:
During processing, there was not enough memory to continue processing.

User Response:
Possible solutions include:

Ensure that your system has sufficient real and virtual memory.
Remove background processes.

Architect Certification (OCMJEA)

passed SCEA 97%

Hi All,

Its great to see this discussion.

recently i've cleared the SCEA (310-051) part-1 with 95% score.

I felt that was easy since that was a multiple choice type exam.

Now I am planning to take up the part-2 exam, but I do not have any idea of where to start from.

Can anyone here help me out to get started for the preparation?

Thanks in advance

2 phase commit in java !!!!!!!!! URGENT!!!!!!!!!!!

Hi,
Can I implement 2 phase commit in a standalone java application ?
I access multiple databases with different connection objects in a single class in a single transaction. But how do I implement the 2 phase commit manually in a java standalone application.
Please note that I dont have any environment(like server, jndi etc.,) where i can deploy the datasources.
So pls let me know whether i can implement distributed transactions in this scenario.
This is very urgent.
