Jul 21, 2009I am having problems with my procedure which is refreshing materialized views. This is the error i am getting : -12008: ORA-12008: error in materialized view refresh path
ORA-01555: snapshot too old: rollback segment number 14...
I have two database with the same procedure and the same objects. They run at the same time, however, there are times when i get the error on the other database while the other database runs the procedure without any error.
When i checked the net, they say that this error is caused by data that is old, so the solution is to make the source a predecessor of my procedure/job. But what i am thinking is that how was it possible for the other database to run it completely even if it is not yet linked as the successor of the source?

Jul 7, 2012After searching a lot on net the differences between inline view and subquery that i came across are
1) you can use order by in inline view but not in subquery.
2) you can use alias for inline view but not subquery.

Replication :: Difference In Using Updateable Materialized View And Multi Master Async
Aug 21, 2008I have 3 sites which want to be updated as soon as the other one updates its data.(in 5 seconds). So I have chosen multi master solution,sync regardless of the resource consideration.
1-what is the difference between multimaster async and updatable materialized view regardless of resource consuming in multimaster?because in both of them each site can receive and also propagate the data...I just know that in materialized view we can work offline and then apply it manually is there any other thing?
2-I can not understand the difference between multimaster sync and async (considering the 5 seconds,because 5 second is a little time)I mean in this case are they different from each other or not.
PL/SQL :: Select On View Takes Long On Definition Short - No Difference In Exec-plans?
Aug 20, 2012[URL]...
I have a quite complex view that selects from approx 10 long tables (approx 4M records each) and build one "customer sentence" pre customer id. I will be always getting just one row from this view, eg. select * from my_view where party_id = XYZ. I'll NEVER EVER select the whole view.
The problem is that running a query:
select * from my_view where party_id = XYZ takes really long time, while putting the party_id = XYZ condition directly into the view executes in 0.0 seconds.
After putting a ORDERED FIRST_ROWS(1) hint into a view the execution plans seems to be the same (or very similar) for both queries. Unfortunately, I can not transfer anything but screenshot from the environmnet - therefore I paste the exec plans as screenshots only - pls follow the link: [URL]...
View DDL:
create or replace view my_view as
select /*+ ORDERED FIRST_ROWS(1) */ pt.party_id
pt.party_id as id_klienta_mdm,
pt.master_reference_no as id_klienta_ref_mdm,

ArchiveLog In Main Database?
Jun 10, 2013I turned on ARCHIVELOG in my main database, anticipating GoldenGate replications and standing up a physical standby database. However, during the process I forgot to create a new SPFILE for my database, meaning that the next time the database cycled, the archive log destination would revert to the Oracle default (rather than the mount point I had set up to receive them) $ORACLE_BASE/fast_recovery_area
. I discovered this because my database hung..... In looking at the ALERT LOG, I discovered that the logs were going to fast_recovery_area, and it had run out of room. OK, so I did an alter system set db_recovery_file_dest_size= 5G scope=both; at which point in time I was notified that no active SPFILE existed! I moved out all of the logfiles that were in the fast_recovery_area, but the database seemed to still think that it was full.
I've managed to get everything fixed and put back together, but my remaining question is: After I freed up all sorts of space in the fast_recovery_area, why did/does the database still think that area is full?
Select From Main If There Is No Record In History
Aug 9, 2010I have 3 main tables as projects, tasks, clients. Then I have a history table for each. I created a trigger on update/delete that takes the old records and inserts into the history.
Now, I need to retrieve the history but I have no clue how to do so. I need to join these 3 history tables with:
1. select from projects_history with projectID = 1
2. if no records, then go back to projects and get projectID = 1
3. select from task_history with taskID = 1
4. if no records, then go back to tasks with taskID = 1
5. select from client_history with clientID = 1
6. if no records, then go back to client with clientID = 1
where client.taskID = task.taskId and task.projectID = project.projectID.

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.

Performance Tuning :: Oracle Server - Analyze Table In Main Database
Jul 13, 2010I have a procedure which mainly run queries on a Table which has nearly 9.5 million recodes. This procedures takes nearly 15 min to complete execution on our main database. I exported and imported the schema to our backup database and the same procedure just took 3 seconds to complete.
I tried to analyze the table in our main database and tried to execute the procedure again but did not show any improvements. ANALYZE TABLE DN_ACTIONS COMPUTE STATISTICS;
I am not sure computing the statistics for all the tables in the schema will work. I also checked there is enough disk space where oracle data files are stored. I am also turning on the sql trace to see what sql statements in the procedure is taking longer time.

Getting Error (snapshot Too Old) - Restructure Code?
Oct 8, 2013we are getting "snapshot too old" error when we executing a procedure. The error details are as below:
"ORA-01555: snapshot too old: rollback segment number 208 with .."
The code framework is below. basically we are having 3 cursor to select data and the base tables seems to update frequently. hence we understood that this error might come. if any other better way to restructure the below code framework.
Create or replace procedure proc1 as
CURSOR C1 is
select a from tab1
CURSOR C2 (p1 VARCHAR2)
is
select * from tab2;
[code]...
Since DBA not willing to change UNDO_RETENTION and other UNDO* parameters, we need to work around with restructure the code.
