View 2 Replies View RelatedError On Table Redefinition With LOB Segments
May 25, 2012share what can we do to over come this issue?We are running 11.2.0.2 on IBM Aix. I am trying to do an redef and this is what i see:
Received an ORA-1555 error on a table redefinition with LOB segments.
ERROR at line 1:
ORA-12008: error in materialized view refresh path
ORA-01555: snapshot too old: rollback segment number with name "" too small
[code]...
As the ORA-01555 error does have a name we know that this is LOB related.We are using Automatic Undo mode and have RETENTION specifed on the LOB segments in both the source and target tables for the redefinion.The LOB segments in the source table are stored out-of-line (DISABLE STORAGE IN ROW) while the LOB segements in the target table are stored in-line (ENABLE STORAGE in row).There are a very large number of updates occuring on the source table. The table is quite large and the redefintion failed after 36 hours.
In oracle documentation we're finding conflicting information as to whether the UNDO_RETENTION database parameter affects the LOB storage RETENTION parameter, and therefore whether increasing our UNDO_RETENTION will be useful in this issue. The SQL manual indicates that it does affect this saying 'Oracle Database uses the value of the UNDO_RETENTION initialization parameter to determine the amount of committed undo data to retain in the database.'
Our current undo_retention is set to 21600.
How can we resolve this ORA-1555 error?
New Tables And Indexes Created Not Show In Dba-segments View?
Aug 8, 2012I have created 3 tables and some indexes, but these objects do not show up in dba_segments view. Is this a normal behaviour? Previously, with dictionary managed tablespace, I can specify the minimum extent to create, when the table/index is created. But I'm not sure how the locally managed tablespace work.
I'm using Oracle 11g R2 (11.2.0.1.0) for Microsoft Windows (x64), running on Windows 7.For the purpose of reproducing this issue, I have created the tablespaces as follow:
CREATE TABLESPACE CUST_DATA
DATAFILE 'd:appasusoradataorcl11gr2CUST_DATA01.DBF' SIZE 512K
AUTOEXTEND ON NEXT 256K MAXSIZE 2000K
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 256K
SEGMENT SPACE MANAGEMENT AUTO;

Server Administration :: Commit And Rollback?
Oct 14, 2010On a huge transaction the buffer cache gets fulled and on that case oracle automatically writes to the data files. And as such when we issue commit statement it does not take more time. It only writes the dirty buffers to the dirty buffers to the datafiles.
When we rollback does the data gets erased from the datafile. What is the mechanism of rolling back ? It should be clearing the dirty buffers for sure.

Server 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?

View 20 Replies View RelatedServer Administration :: Taking Partitions Offline In Tables
Feb 4, 2012In an attempt to take older data off line and allow database refreshes to be faster, tablespaces associated with partitioned table data for a given time period was taken off line, leaving only tablespaces that relate to the current time period online. In effect, tablespaces related to 2010 and earlier were taken offline from a table.
1. Without giving a filter on the partition key (the business date) to scan for data greater than the dates in the off lined tablespace partition, we get a ORA-376/ORA-1110 error (data file cannot be read at this time).
2. Materialized views using fast refresh or refresh on commit, will also not work because of the partitions being off line.
Queries directly querying the tables are manageable from an application point of view.But the materialized views failing to aggregate is a bigger problem.
how we can manage this situation? I know that I can move the partitions to a different table in a tablespace to be taken off line. But if possible, we wanted to solve this without doing a move partition.
