RAC is not related to standby database. DataGuard is the big enhancement for standby databases in 9i. RAC is the name for the 9i incarnation of OPS (Oracle Parallel Server.). If the database to be mirrored, then it is completely independent of OPS/RAC - which shares a single database. It could be a standby database, geo-mirroring, ...

However, looking at your words Oracle has a product . . . database to be mirrored for reporting purposes, he might be referring to Oracle9i's Real Application Clusters. In the Oracle 8i incarnation, there was a limitation with a standby database. The standby could be made current by applying the redo logs from the production database (using recovery), then opened and used for reporting. But you couldn't have both - currency and reporting. I think I heard that with Oracle 9i RAC this limitation has been bypassed so you can do reporting while the logs are continuing to be applied. Don't take my word for it (this is Friday after all), but you might want to look at RAC, and maybe someone more knowledgeable than me will respond on this list. Dennis Williams DBA Lifetouch, Inc.

Re: Buffer Busy Waits -- Sanity check please
Malcolm, The paragraph below would indicate that readers are blocking. Readers don't block in Oracle. The only reason I can think of at the moment for a SELECT to cause buffer busy waits is delayed block cleanout, of which there has been a lot of discussion lately. I could be all mixed up here I guess, it's Saturday and I dont' want to think too hard about all this.

RE: Has anyone heard of Mirror Accessible?
AFAIK, 9iDataGuard in the current release is only a Physical Standby database (not logical standby database). This is similar to 8i except for the fact that, if you ensure that you do a clean failover-and-failback (ie have the controlfiles and online redo log files available) you can actually switch to and from the standby. Never tried it and wouldn't try it till 9.0.2 (at the minimum) Hemant Miller, Jay [EMAIL PROTECTED]01/12/2001 05:45 AM Sent by: [EMAIL PROTECTED] Please respond to ORACLE-L To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] cc: (bcc: CHITALE Hemant Krishnarao/Prin DBA/CSM/ST Group) Subject: RE: Has anyone heard of Mirror Accessible?

RE: Buffer Busy Waits -- Sanity check please
The P3 value of 130 on the buffer busy waits does indicate that the block is being read by another process as Malcolm stated that's the process doing the scattered read (Full table scan). Oracle needs to protect the block while it is being read. The others sessions are waiting until the read of that block is complete. For a definition of the P3 values see Steve Adam's website http://www.ixora.com.au/ His full explanation of P3 id 130 is 1013Block is being read by another session and no other or 130suitable block image was found, so we wait until the read is completed. This may also occur after a buffer cache assumed deadlock. The kernel can't get a buffer in a certain amount of time and assumes a deadlock. Therefore it will read the CR version of the block.
