Re: Recovery from noarchive db corrected
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=pfile_path SVRMGR alter database archivelog; SVRMGR archive log start SVRMGR alter database open; SVRMGR alter database backup controlfile to trace; SVRMGR archive log list Paul Sinardy Xing wrote: Currently the application insert data from batch localy and a bit from online insertion.

RE: Recovery from noarchive db corrected
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.

Re: Recovery from noarchive db corrected
Sinardy Xing wrote: The developer application running huge batch inserting data into database, that is what they told me, if you are me what you will do? 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. David A.

RE: Recovery from noarchive db corrected
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.

RE: Recovery from noarchive db corrected
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! -a [EMAIL PROTECTED] 6/4/2001 14:45:28 This message has been scanned by MAILSweeper.The developer application running huge batch inserting data into database,that is what they told me, if you are me what you will do?-Original Message-TestaSent: Friday, 6 April 2001 11:55 AMTo: Multiple recipients of list ORACLE-Lassuming you're the dba, since when does the developer dictaterecoverability to a DBA about a database.sounds like a role problem there.joeSinardy Xing wrote: Our Developer prefer the archive off, I can't change that anymore :( -Original Message- Sent: Thursday, 5 April 2001 8:54 PM To: LazyDBA mailing list Turn archiving on. -Original Message- From: Sinardy Xing [mailto:[EMAIL PROTECTED]] Sent: Thursday, April 05, 2001 4:57 AM To: LazyDBA mailing list Subject: Recovery from noarchive db corrected Hi, My database is noarchive mode, what should I do to prevent from lossing any transactions ?
