It sounds as if you may need to revisit your requirements. This would create
a file too large to work with. Has Oracle Support requested it?
Is the job not very repetitive so that any five minutes will look virtually
identical (assuming it is one single batch process). If that would be the
case, you would only need a trace for a short period.
If yo need all of this trace data, then you could copy from it to another
file and then truncate it ( echo '' > <file>). That resets the file pointer,
while not changing the inode for the file. While you're copying and
truncating the file will be written to so make sure you're not missing some
data or getting half written records, you will want to pause the process. In
Solaris that should be possible with the pstop command. It requires root or
logging in as the owner of the process.
