Server Administration :: How To Check Error ORA-01555 / Snapshot Too Old
Dec 23, 2011i am getting this error during expdp ORA-01555 -snapshot too old
1. i increased undo_retention i.e 50000
2. i execute expdp during late night when almost zero user is online so no commit from any other session.
3. we have a table having BLOB data type field in a table which is 500 GB in size.complete DB size is 700 GB
where and why this error exists.if corruption of BLOB so how to check that etc. the same error is occurring in three of our data centres during expdp.

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?

View 6 Replies View RelatedServer Administration :: Rollback Segment Too Small ORA-01555
Jan 19, 2012One 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?
Performance Tuning :: ORA-01555 Required Old Image Is Not In Undo
Sep 22, 2011I am getting the below error in alert log file,when my application calling a procedure.
ORA-01555 caused by SQL statement below (Query Duration=1576 sec, SCN: 0x09a2.5dda3165):
Fri Sep 16 16:33:40 2011
UPDATE SSPT_NETWORK_DETAILS SET INCLUDE_OFFERS = 'Yes' WHERE SESS_ID = SESS_ID
There is no ROLLBACK statement in my procedure. As per my understanding, the ORA-1555 error will occur,
1. The required old image is not in the undo,when we rollback the trasaction.
2. the select query may face this error because of delayed block cleanout concept.
But I don't know why this update statement causing this 1555 error?

Following are the details in AWR report (00:00 til 01:00 of 21-Apr-2013) .... not thet the error was produced at 00:42
Undo Segment Summary DB/Inst: DBCPY/dbcpy01 Snaps: 18853-18854
-> Min/Max TR (mins) - Min and Max Tuned Retention (minutes)
-> STO - Snapshot Too Old count, OOS - Out of Space count
-> Undo segment block stats:
-> uS - unexpired Stolen, your - unexpired Released, uU - unexpired reUsed
[code]....
Undo Advisor information taken 'now' is as following
SQL> select dbms_undo_adv.longest_query(sysdate-2,sysdate) from dual;
DBMS_UNDO_ADV.LONGEST_QUERY(SYSDATE-2,SYSDATE)
----------------------------------------------
379650
SQL> select dbms_undo_adv.required_retention from dual;
[code]....
In above situation what should be my first choice (assuming increasing space is not an issue) - increase undo tablespace or increase undo retention?
If latter is the choice then what should be the value? Because as I understand present 96000 value is taken as lower limit and because of auto tuning the actual value (TUNED_UNDORETENTION) being used was 345600 In that case shall I set it to something > max(maxquerylen) i.e 379,650 + X?Or I shall increase the undo tablespace size?
From Undo Advisor output it looks to me that even if I increase the undo retention to 379650 current undo size will be able to support it (may be at the expense of DMLs)Is that right?
Performance Tuning :: ORA-01555 - No Unexpired Or Expired Blocks Were Over Written?
May 10, 2011I have encountered ORA-01555 and trying to find what caused the issue.
#UNDO parameters

set pagesize 25
set linesize 120
select inst_id,tuned_undoretention,to_char(begin_time,'MM/DD/YYYY HH24:MI') begin_time,

at the end you can see there is one occurance of ORA-555, but no Unexpired or expired blocks were over written .why Oracle didnt try to use them ?

SQL & PL/SQL :: Mutating Error?
Oct 20, 20131.I have created table emp_log using structure of emp table
create table emp_log
as select * from emp
where 1=2;
2.Now I have added some new fields i.e
new_sal(updated salary) ,
upd_by (who updated),
upd_date (Salary update date)
alter table emp_log
add (new_sal number, upd_by varchar2(20),upd_date date);
3. I have made following trigger to insert old and new values (for salary,user and date) in emp_log table whenever I update sal for particular employee in emp table and at the same time i am selecting the updated value of sal into lv_sal variable which will cause mutating error.
create or replace trigger emp_trg
after update of sal on emp
for each row
declare
[code]...
4. Suppose sal of emp is 1000:-
update emp
set sal=sal+100
where empno=7369;
>select * from emp_log;
output:- sal= 1000 new_sal=1100
[code]...
Now the question starts if i commment pragma autonomous_tansaction and commit statement then it gives mutating error because at the same time i am updating and selecting value of sal from emp table.
create or replace trigger emp_trg
after update of sal on emp
for each row
declare
[code]...
Questions:-
1.Is pragma autonomous_transaction handling the mutating error and if yes then how?
2.How many ways are there to handle mutating error.
3.What is the exact definition of Mutating Error.
4.An example or query to use lv_sal variable for printing new updated sal.
5.What is Mutating Table , Is it similar to mutating error (Found this topic while searching for mutating error).
