Apr 21, 2012Why do we gather table statistics manually ?Is it because of database performance.
I know In Oracle Database 10g, Automatic Optimizer Statistics Collection reduces the likelihood of poorly performing SQL statements due to stale or invalid statistics and enhances SQL execution performance by providing optimal input to the query optimizer.
Optimizer gathers statistics when 10% table rows have been changed.

Server Administration :: Impact Of Up-to-date Statistics On Main Schema Objects
Feb 29, 2012I am looking at a performance issue at the moment and trying to replicate on a test system. I am initially looking at the impact of upto-date statistics on the main schema's objects.
For this I wanted to:
first run the batch with whatever stats were present in the database Flashback the db to before the batch . Gather stats Re-run the batch with updated stats and compare results.
However, I inadvertently ran the stats job before running the load the first time! I have the SCN from when the environment was set up like production (ie before the stats were run) so am I correct in saying that if I flashback to this point then the stats will be "old" and I can just run the batch then? I know I can verify this when I Flashback the database by looking at LAST_ANALYZED on tables etc but it would be good to know this before hand as it's a 12 hour batch.
SQL & PL/SQL :: DBA Pending Transaction In Database
Jun 16, 2011application was not starting due to some pending transaction in database.Pending transactions were rolled back by DBA team.To avoid such situations what I thought was, having a job that will call a procedure that will monitor table status everyday and will send the mail. Now that job is working fine for no pending transactions in DBA_PENDING_TRANSACTIONS.
But now I am in doubt if someday there are PENDING TRANSACTIONs in the table DBA_PENDING_TRANSACTIONS, will SELECT * FROM DBA_ PENDING_ TRANSACTIONs query will work as normal or this whole process of monitoring table and sending mail will work fine?

SQL & PL/SQL :: Exclude Single Schema From Autostats Gathering Feature In 11g
Jul 5, 2011I need to exclude a single schema from the autostats gathering feature in 11g. The tables in this schema are analyzed at the appropriate time via the application code. The autostats gathering job sometimes kicks in at a time in which the tables are getting updated or loaded which can skew explain plans during the updates/inserts.
I've searched through the oracle documentation and cannot find a way to simply "exclude" the schema without locking it. I see it is possible to disable the autostats at the entire db level but not at the schema level.

Active Data Guard Feature Of 11g To Run Live Reports On Standby
Sep 26, 2012We have 10g physical standby set in our environment and we are migrating to 11g now. We want to use the active data guard feature of 11g to run the live reports on standby rather production. Questions I have is:
1) On our current 10g standby environment, we use db_name=cusms which is exactly matching with the production database name. I don't see we are using database_unique name on our standby. But I have read several blogs where everyone talks about using db_unique name on standby and db_name can be exactly matching with production on 11g. I wanted to know, is db_unique name a new requirement to have on 11g? can I go ahead and not use db_unique name and just have db_name exactly matching with production? What are the implications of doing so? The reason we want to stick to this is in-case of failover we want the database name to be the same. But I want to hear your thoughts on this:
2)While building standby, I did noticed few things and want your clarifications:
a.On standby database, should I mount instance using pfile or spfile or it doesn't matter?
b. Lets say if I use either spfile or pfile, can I just have db_unique name in that file and just start the instance in no mount and do the duplicate from rman?
c.As soon as my duplicate target database for standby from active database got finished, I usually exit the rman session and go to sqlplus and shutdown the standby instance. (Is this ok to do)
d.Then I start the standby instance with startup (mount and open the database) this should open the standby database in read only mode. Following I issue alter database recover managed standby database using current logfile disconnect to put the database in recovery mode. (any steps missing here)
e.Then go to primary and do few log switches and come back to standby to see if the primary changes moved to secondary or not.
But what I have observed is:
a. When I do the duplicate it runs successful. But during the course of duplicate, primary system generates few archives which are not shipped or applied on standby. When I go to standby to recover the database, it says media recovery needed and ask for archives files. I need to manually move this files from primary to standby to apply. Isn/t this automatically taken care?
b. I also noticed after I can not open the standby database in read only mode after the duplicate command. While trying to open, it says database media recovery needed. What's the best procedure to open the database in read only mode immediately?
c. On my standby init.ora lets say if I use db_unique name, where would my control file be place? Will oracle create controlfile from primary and put it on my standby database and put an update an entry into my pfile or spfile?

SQL & PL/SQL :: Sequence Increments When It Is Not Being Called
Dec 1, 2012I have a table called "Subjects" which lists subjects to match with notations in another table I have created a simple sequence (CREATE sequence subjectid) to created the subject id for the table. But I notice that if there is a skip in the date, the sequence increments automatically when I am not even using it. It even appears to be incrementing even when I am not doing any database activity.
This is not an issue of data integrity, because the values in the subject_id column do not need to be sequential, they just need to be unique. But it really has me curious. I created another table called "keep_track" to keep track of what is happening:
