I run the following command ...

load from mycursor of cursor replace into <table_name> copy yes to c:\test check pending cascade immediate

After running the command :
In folder C:\test , the following 2 files got created:
DBNAME.4.DB2.NODE0000.CATN0000.20090525163235.001
DBNAME.4.DB2.NODE0000.CATN0000.20090525163237.001

__________________________________________________ _________________

I understand that these two files create the backup of data during the Load

I tried using DB2 RESTORE command:
DB2 RESTORE DATABASE DBNAME FROM "C:\test" TAKEN AT 20090525163235 WITH 2
BUFFERS BUFFER 1024 PARALLELISM 1 WITHOUT PROMPTING

And got the error:
SQL2542N No match for a database image file was found based on the source
database alias "DBNAME" and timestamp "20090525163235" provided.

Please tell me what is the use of the two files created suring DB2 load.
And How exactly can I use it for recovery.

The COPY YES option does not create a backup image, so you cannot use the RESTORE command the way you tried. The data collected by that option contains information that is necessary to roll forward the LOAD command. The proper way of restoring a database in this situation would be to RESTORE a backup image taken before the LOAD, then ROLLFORWARD to a point in time after the LOAD.

You can't restore from this image. This image will be used by db2 during the rollforward.

OK. I was trying to know the usability of the files created after I run the Load command
namely
DBNAME.4.DB2.NODE0000.CATN0000.20090525163235.001
DBNAME.4.DB2.NODE0000.CATN0000.20090525163237.001


What is the way, that gets used? and how?

So, is there any way the user can use it?.....by what command...?

This image is only intended to be used by db2 itself during the rollforward. It will be read when db2 encounters a LOAD ...COPY YES log record.

So once the Load command completes, these files still remain ,
So, are they of no use for an end user to use at all?

Yes, they're for db2 internal use only, not for any end users at all.
