Subject [jira] Commented: (DERBY-4213) sttest needs to be adjusted to not run out of disk space
Date Tue, 18 Aug 2009 23:52:14 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12744785#action_12744785
] 

Myrna van Lunteren commented on DERBY-4213:
-------------------------------------------

I tried to replace the section in utils/CompressTable.java which looks like it tries to compress
the Datatypes table, with a call to SYSCS_UTIL.SYSCS_INPLACE_COMPRESS_TABLE(.,.,.,.,.), but
so far, I don't see the compress being called.
However, I notice that although there's code that deletes rows being call, but only very,
very few rows actually get deleted - most of the deletes find no rows to delete.
At which point I don't think compress would do much anyway.

I'm take a closer look at the delete rows code.

>                 URL: https://issues.apache.org/jira/browse/DERBY-4213
>             Project: Derby
>          Issue Type: Improvement
>          Components: Test
>    Affects Versions: 10.5.1.1, 10.6.0.0
>            Reporter: Myrna van Lunteren
>            Priority: Minor
>
> After eliminating some NullPointerExceptions for 10.5.1.1 (which I noticed with 10.5.1.0
testing but had also been present with 10.4.2.0) the sttest runs out of disk space before
all threads are done. 
> Before, with the NPEs, the test would run its course in a day or two.
> The test should be adjusted, with perhaps more deletes, so that it will no longer run
out of disk space.
