2001-04-05 Thread Sinardy Xing

assuming you're the dba, since when does the developer dictate
recoverability to a DBA about a database.

sounds like a role problem there.

Sinardy,

Who will recover the database in case of a failure?

Turing on archiving would not hinder performance so much.
Proper planning of your backup strategy and db setup will have little
overhead 
on performance of your database.

You cannot sacrifice backups for a marginal increase in performance
especially if
your db is a high transaction processing system.

Suhen

RE: Recovery from noarchive db corrected

2001-04-05 Thread Arn Klammer



The actual archiving of log files itself should not impact the 
performance of the insert jobs, unless the archiving process is slow enough to 
cause the database to pause while a log is archived so it can be reused.  
The only other reason why the developers wouldn't want it is if the space 
required to store the archived logs impinges on their development space; in that 
case, you'd have a case for getting more storage.  Either way, the 
inability to recover a database due to the absence of logs is far 
worse!

RE: Recovery from noarchive db corrected

2001-04-06 Thread Hallas, John

FOR YOUR INFORMATION

ESIS and EPFAL are now part of Logica. The Internet email addresses of the staff has 
changed to the following - [EMAIL PROTECTED] eg [EMAIL PROTECTED] Emails 
using the old format will continue to be delivered until 30th June 2001. 

With no disrespect to your English, the phrase "weakly copy of dbf files"
(rather than weekly) seems rather appropriate.
As several other listers have stated, by far the best option is to enable
archive logging. 
Whilst you seem to have the bases covered, have you considered how long it
will take to re-apply the batch files and whilst there may not be much
online input you  are running the risk of losing all data that has been
input after your last export and before the next one.

Best advice seems to be try archive logging and identify the impact then
make a considered judgement.

RE: Recovery from noarchive db corrected

2001-04-06 Thread Hallas, John

The normal method is to copy out the days worth of archive log file as part
of your normal backup routine. Then maybe keep 2 days worth on-line so that
they are available for  a recovery without getting them back from tape.

Keep a watch on the disk space to ensure that the disk does not get full and
a new archived redo log cannot be created.

Sinardy,

Who will recover the database in case of a
failure?

Turing on archiving would not hinder
performance so much.
Proper planning of your backup strategy and
db setup will
have little
overhead
on performance of your database.

You cannot sacrifice backups for a marginal
increase in
performance
especially if
your db is a high transaction processing
system.

I would tell them that THEY are then responsible for database recovery if a problem 
should occur.  If the DBA is to be responsible, then the DBA should be able to utilize 
the recovery tools provided by the vendor (Oracle).

Sinardy,

You definitely want to turn archiving on.  

Without it, your recovery options are limited to the last offline backup
of the database.  If you do an offline backup of the development DB
every night, then the most that would be lost is one day's worth of
development.  Depending on how and where the developers write and store
their code, the least that would be lost is one day's worth of
transactions in the development DB.

Beyond that however, is the fact that you are a developer in a sense as
well.  Tuning databases to avoid the kind of contention the developers
are worried about is part of what you do for a living.  If the
developer's fears are correct, and archiving causes their database to
respond poorly, what will happen when their code goes into an archived
production database?  There are many parameters you can alter and steps
you can take to reduce, minimize, or eliminate this type of contention. 
Combinations of things like adding redo logs, increasing the size of the
log buffer, altering checkpoints, looking at v$latch and making
appropriate adjustments to log_small_entry_max_size or
log_simultaneous_copies are just a few of the options available to you
as the DBA.  Examining the code processing the batch is another.  

Tuning is like detective work, and is probably my favorite part of being
a DBA.  Start with one of the tuning manuals off OTN, then pick up (and
read) Steve Adam's "Oracle 8i Internal Services" from O'Reilly.

You'll be a better DBA, and who knows, you might even be able to teach
the developers a trick or two.

Good Luck.

Here, here!!!  If they can dictate the fact the the DB will not be in archive log

Re: Recovery from noarchive db corrected

2001-04-07 Thread Paul Drake

Sinardy,

what's your uptime requirement?
You're allowed a weekly cold shutdown for backup?
what I'm asking is - when you are copying the datafiles to tape, its
during a clean, cold shutdown, right?
Have you ever tested the recovery portion of your backup/recovery
scheme?

If your 'copying files to tape' is from an open database, you'd be in
for a real surprise when you attempt to restore the full set. You have
no other recovery options than the full set - its zero datafiles or all
of them.

If you create your batch loads so as to minimize the amount of redo,
archivelog might not seem like such a performance hit.
Give the system a dedicated channel and pair of drives (each) for both
online and archived redo logs, and don't worry about the performance
hit.

try it, you'll like it:

SVRMGR> startup mount pfile=

SVRMGR> alter database archivelog;

SVRMGR> archive log start

SVRMGR> alter database open;

SVRMGR> alter database backup controlfile to trace;

SVRMGR> archive log list
