Unfortunately, from your description and the lack of definition of your acronynms, one is not sure what you are trying to do. If you are trying to do basic 'log shipping' then you need to start the second/standby dataserver with the -Q option and then simply apply the log dumps in same sequence as dumped.
With respect to the dump location, that is set by the dump tran command - it looks as if for some reason, someone's code didn't change the timestamp info for the dump tran - hence the dump file name was the same. It appears that the HHMMSS logic is set incorrectly for both dumps, so perhaps this is set at the beginning of the loop and then forgotten to be modified in the loop????
