Subject [jira] Commented: (DERBY-1693) Out of Memory Error with derby.language.logStatementText=true
Date Mon, 21 Aug 2006 10:47:14 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1693?page=comments#action_12429382 ] 
Kristian Waagan commented on DERBY-1693:

I agree that the values for LOBs should not be printed.
The question is what should be printed instead?
I would go for either 'BLOB'/'CLOB' or 'BLOB(<length>)'/'CLOB(<length>)'.
I fancy the latter the most, but I do not fully understand the complications of obtaining
the length wrt "length less LOBs". For instance, materializing it to determine the length
is unacceptable in my opinion.

>    Affects Versions:
>         Environment: JVM INFO :
> java version "1.5.0_02"
> Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_02-b09)

> While running a test with blobs and clobs of random size but not exceeding more than
5MB , with derby.language.logStatementText=true , The inserts are faling with out of memory
error. Once that error occurs then the test loses all connections to the database. If I take
off the derby.language.logStatementText=true property from derby.properties, the test runs
fine. Here is the stack Trace
> java.lang.OutOfMemoryError: Java heap space
> ---SQLException Caught---
> SQLState:   XJ001
> Severity: 0
> Message:  Java exception: 'Java heap space: java.lang.OutOfMemoryError'.
> java.lang.OutOfMemoryError: Java heap space
