Problems with IBM Digital Library under UDB DB2

Hello,

I'm working with the IBM Digital Library 2.4 under DB2 v 2.4.

Lately I'm getting some errors in retrieving of the pages, the digital images, even I have deleted all the images of a folder and the folder and I have recreated it again and when I try to access to those images I get an error, both in Digital Library Client and via web by Net.Data.

I don't know the cause of this problem, perhaps it may be due to DB2 performance, the message we get is the following:

DTWF023E: Net.Data is unable to execute the SQL statement DGL0368A: Error while retrieving a part, API:SimLibOpenObject [FRN=6264,ExtRC=0].

, he buscado en los códigos de mensajes de error y lo que dice es :

"FRN6264A The object server cannot get the object.
Explanation: The object server could not read in the object because the object was erased or renamed.
#Define: SIM_RC_OBJSERV_CANNOTRETRIEVE
Action: Store the object again"

I have proved that the images exists.

Note: we use a ADSM storage like the last step of migration, but even with the most recently incorporated documents we get the error, mainly in peek hours.

Thank you very much for your attention, and excuse me my bad english, sorry!
