Subject [jira] Commented: (DERBY-3354) Select from large lob table with embedded gives OutOfMemoryError
Date Tue, 12 Feb 2008 17:19:08 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3354?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12568226#action_12568226
] 

Kathey Marsden commented on DERBY-3354:
---------------------------------------

Also should the removeLobMapping calls be removed from LobStoredProcedures.BLOBRELEASELOCATOR
and CLOBRELEASELOCATOR now that the release happens in free()?

> Retrieving from a large table with lobs gives an OutOfMemoryException, even if free()
is explictly called on the lob.   I believe this is because EmbedConnection.addLobMapping
is called for every lob creation but is never cleared until commit or rollback, even if the
lob is freed.
