We are running a query in one of our databases using the database the link. The query fails in the middle with "ORA-01555: snapshot too old". Not sure, about the database which this error message points to? Will it be the database we have logged in or it is the database where db link points ?
I have a problem regarding with Oracle Flashback Query.if I'm doing flashback a database two hours before,I'm receiving ORA-01555: snapshot too old error.My question is:How to able to extend the based on the hour or day?

I 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?
I am getting the ORA-01555 Snapshot Too Old error while excecuting my procedure (which is running in OLTP system). My procedure contains one table which master table of my DB which holds 1.2 GB of data. The proc is using the MERGE statement which is inserting or updating the data in the master table, while the condition of MERGE is using the subquery in which 2 DBlink table is used (in which one table is updating quite frequently). The proc. is executing in the interval of 6 hrs i.e 4 times a day and its is scheduled in job. find the proc. as an attachment.
One of the users received the error ora-01555: rollback segment too small
I have read about the error and saw that it is caused by transactions made upon same data, filling to maximum one of the UNDOTBS rollback segments.It happens only once in a while, each time on a different Rollback Segment.
I've read that i should do a few things to enlarge those segments, such as bring a 1. segment offline, 2. drop it and then 3. create it with a bigger size & possibly a bigger extent setting
i've also read that those actions aren't relevant if you have the parameter UNDO_MANAGEMENT set on AUTO, which is actually the case.is that why when i execute ALTER ROLLBACK SEGMENT RB_SEG_NAME_11$ OFFLINE;
1. How do i solve my issue with the Rollback segment being too small to contain the snapshot with the requested SCN?
2. what does the parameter UNDO_MANAGEMENT mean? should i change it, in order to adjust my Rollback Segments attributes, to prevent my error of re-occurring?
I am getting below ORA-01555 error in alert log everyday.
ORA-01555 caused by SQL statement below (SCN: 0x09ad.86a4562a): Sat Jan 21 08:39:45 2012 SELECT (NVL(MAX(BLOCK_ID + BLOCKS ),0) * :b1 ) / 1024 FROM DBA_EXTENTS WHERE TABLESPACE_NAME = :b2 AND FILE_ID = :b3
I cannot able to find the sql_id here. So how can I find from which process or session this query is firing? before increasing the undo size, I need to analyze as why it is occuring?
I've got to collect statistics by DBMS_STAT. For the first time, the spcreate.sql is to be called, however, it returned one error following:
If this script is automatically called from spcreate (which is the supported method), all STATSPACK segments will be created in the PERFSTAT user's default tablespace.

And then, I checked it again with its owner:

Then, I checked again after dropping schema PERFSTAT:

How can i check a partition whether it has been compressed? just as flowing test,i can not get the information about partition P_L1 whether been compressed.

quick check on a hidden parameter? I need to know the default value and possible values for _serial_direct_read on various releases, I have only 11.2.0.3 available right now and I'ld like to know this for 11.2.x.x 11.1.x.x, and 10.2.x.x.
Below is the query that will show what it is currently which (unless you've changed it) will be the default: auto for my 11.2.0.3. Then to see the options, try to set it to something wrong, my options are false/true/never/auto/always. I think false/true were the only choices for 10.2 and are maintained only for compatibility. But I can't rememebnr 11.1.

Actually in our environment , sysadmins are upgrading java versions on Unix (HP & Solaris) Machines and they have asked the query whether oracle database uses Java or not?
If it uses then all the databases need to be shut down for their planned activities and if not no need to shutdown the databases.
I need to display the parameter and status of DB for listener and Read Only.
I know those value could be get from command line , but could we get the values of Listener and Read only by SQL/PlSQL? So I can get it through the query of DB.
we 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.
We are getting the below errors while migrating partitioned tables using expdp.
The source and target databases are both running on 10.2.0.5 and the main thing is source database doesn't have any active sessions. This is a clone of a Prod Database and no one is accessing it.

It's been 2 days from now that I'm bugging with this kind of error in my manual dB creation. I used DBCA first but we had a default directory settings, that's why I resorted to create the db manually. The dB was already created and currently has a status of STARTED.. I cannot mount it due to this error:

I am installing oracle10 10.0.4 in windows server 2008 r2 sp1. while installing it is getting installed and when i start creating the database after accepting the default steps finally . while crating the error i get TNS:protocal adaptor error.
