Subject a few questions to Apache Derby Database
Date Fri, 18 May 2012 08:32:11 GMT
Dear All,

I have the following questions to Apache Derby Database:

1.       Does Derby have any limit on the database size? ( the size of our Database is about
3,1 GB )

2.       Dose Derby have any problems to manage database sizes over 1GB?

3.       We have with Derby database many performance problems, we got some times  an Out
of Memory Error because of Java heap space, and our Server was down, the error was like follows:

 

2012-02-23 12:41:58,353 ERROR - Error in ID LOGIK call:

2012-02-23 12:41:58,353 ERROR - Service: scores.GetAllCasesFiltered

2012-02-23 12:41:58,353 ERROR - Parameter: {IP=192.168.144.72, MODULE_ACTIVE=true, CASE_ID=*,


SESSION_ID=zisruwoldl_C0A89048_1329995925686, DEPARTMENT=*, MODUL=9, PROXY_MODULES=ID_SCORER_PKMS,
LASTNAME=*, FIRSTNAME=*, WARD=*}

2012-02-23 12:41:58,353 ERROR - Throwable: Java heap space

java.lang.OutOfMemoryError: Java heap space

 

Is it because of the size of our database (3,1 GB!)? and what can I do to improve the performance
of the Derby Database, and to resolve the error?

 

 

Thanks,

and best regards

 

 

Mit freundlichen Grüßen
