For the ALTER SYSTEM ARCHIVE LOG CURRENT statement,
the Oracle documentation (for 8.0.6) doesn't indicate whether
the
command returns before the log files are archived or not.
Right now, my "hot" backup script includes a pause of 60 secs after the ARCHIVE LOG statement completes, just to give the arch process time to complete the required tasks.
My Question:
Does the ARHIVE LOG statement wait until after the log files
are archived (written to disk) before it returns ? Is it
possible
for the statement to return before the log file is archived ?
Oracle 8.0.6 (32-bit) on HP-UX 11.0
Does anyone know where this is documented ?
