The problem here is that the command line is ambiguous.

The -x option can be followed by a size (for example -x 1024) or it can be specified on its own which is equivalent to -x 0.

Dbmlsync assumes that if the thing following a -x does not start with a - or a / then it is the size. This is the correct assumption unless the -x comes immediately before the offline log directory which is the only command line option that does not start with a - or a /.

So in the case above dbmlsync is trying to treat c:\my\offline\log directory as the size parameter for the -x option. It cannot convert this value to an integer so it reports an error.

There are 2 ways to work around this:

1. Replace -x with -x 0.
2. Rearrange the options on the command line so that the -x option does not come immediately before the offline log directory. (ex dbmlsync -x -c uid=dba;pwd=sql c:\my\offline\log\directory
