I want to alter a very large table.
ALTER TABLE MYTABLE ADD
(
ENTRY_TSTMP DATE DEFAULT SYSDATE NOT NULL
)
My table is very large and I am getting an error saying I am out of undo space.
The dba says the undo space is as big as the table.
Can we find out no of undo segments in undo Table space ? If so , how to find? what's their max limit ?
View 9 Replies View RelatedI am using Oracle 10.2.0.3. Since yesterday i am seeing a session with sid 1160 using undo tablespace but not able to find how much it is using .I need to know which session and from which module and how much is the Undo being used by those sessions. I have tried searching but all the queries provide me with some different results each time.
Also i need the same information for REDO being generated .
alter index test_idx1 shrink space;
I've heard that this statement causes a table lock but cant find any information on this.if it is so, is it a write lock or also a read lock of the table?
Query to find out who is eating up most of the undo space and what query he is running..
View 3 Replies View RelatedI have a long running transaction (more than 3 hours), and at the same time other operations are occurring on different tables, using the same UNDO space.
Sometimes we see ORA-30036, but this error occurs very late in the process. The transaction normally takes 3 hours, but when UNDO space is full, we do not get ORA-30036 upto 8 hours or 9 hours of process.
I am wondering what could be happening in the background, when UNDO space is full, which makes the transaction to extend upto 8 hours or 9 hours (pl. note, this transaction gets completed within 3 hours normally). This is in 11g, UNDO space is managed manually.
I have some question about the parameter RESUMABLE 10G. My quesition is suppose if i am running a expdp process and if there is no space left on the file system the export fails. So in this case if we set the RESUMABLE parameter in the DB will it be useful to resume the expdp from where it fails or it will useful if we schedule a job for the export.

regarding sizing undo tablespace and undo_retention parameter.we have to implement the database in production system with 40 users but how much space should be allocated to undo tablespace is there any propotions related to virtual memory and the
parameter.i have gone thru oracle doc's and some related sites.its an ERP aplications that contains 20 modules .I am an new one to this dba level
Just now sysaux resized to 600m from 250m >>
Sysaux Tablespace is running low. WE SET AWR RETENTION TIME=60 DAYS. WE ARE NOT INTEREST TO EXTEND SYSAUX TABLESPACE SIZE.
Usually we take AWR weekly once. Some times we did ADDM report and ASH.
CODEsql>select TABLESPACE_NAME, FILE_NAME, BYTES/(1024*1024), AUTOEXTENSIBLE, MAXBYTES/(1024*1024) from dba_data_files where tablespace_name = 'SYSAUX';

1. What's the best SOLUTION ?
2. Can i shrink sysaux tablespace ?
3. I think , The size for all occupants in sysaux tablespace is less than 200 MB => how to find actual content of sysaux tablespace ?
4. What could be the reason for growth? Is there any way to free the space from sysaux table space?
Flashback query is working fine for dropped table,but throwing error when trying to get back the previous date by dropping a column from a table.
FLASHBACK TABLE emp TO TIMESTAMP TO_TIMESTAMP('2013-07-13 05:00:00', 'YYYY-MM-DD HH24:MI:SS')
SQL Error: ORA-01466: unable to read data - table definition has changed
Is that a limitation of Oracle by not having query to flashback a column but a table.
How do I perform Undo a drop table operation?

I created a DDL trigger which manipulates columns of a table after an "alter table" statement.
For us this was all the time
"alter table XXX add NEW_COL varchar2(20)"
or
"alter table XXX modify NEW_COL varchar2(20)".
Unfortunatly we have now a requirement which statements "alter table XXX drop NEW_COL varchar2(20)".
My trigger works fine - you see no problem directly after statement execution but the table is then in an invalid status.
The connection will be destroyed after you tried to see the data of this table.
Also the export (creating a dump) will not work.
The problem I see is that I the database will do a "modify" on a column which has internal the status "dropped".
How I can get the information what kind of alter table statement will be executed?
Or is there any chance to select only columns from USER_TAB_COLUMNS without the "dropped" flag?
create or replace trigger TRIGGER
after alter
on SCHEMA
declare
vCharSet NLS_DATABASE_PARAMETERS.VALUE%TYPE;
begin
-- Select all columns of a table
select COLUMN_NAME, DATA_TYPE, DATA_LENGTH
from USER_TAB_COLUMNS
where TABLE_NAME = vTABLE_NAME; ...
-- Loop for all columns from our select
...
vSTATEMENT := 'alter table ' || vTABLE_NAME || ' modify ' || VOBJECTREC.COLUMN_NAME || ' ' || VOBJECTREC.DATA_TYPE || '(' || vNEW_DATA_LENGTH || ')';
--For example:
-- alter table XXX modify NEW_COL varchar2(20)
execute immediate vSTATEMENT;
exception

end;

I have a table with usernames and passwords. The passwords are stored in plaintext. I would like to issue an ALTER command on the password field to store a hash instead, and then repopulate those fields with an encrypted version of the plaintext passwords that were there before.
I would prefer to do this in a procedure, as I am going to perform it in a test environment first, then eventually in the production environment.

I altered existing table EVENT_SUB - added 3 columns. After that, I noticed all the procedures which had mention of this table name went in INVALID status, even if its simple SELECT, ALTER OR INSERT as shown below..
SELECT * FROM EVENT_SUB
OR
INSERT INTO EVENT_SUB...
OR
ALTER TABLE EVENT_SUB
WHERE....
So I had to recompile all the procedures associated with it. Is there any other ways to achieve this, like a line of code to add in the procedure itself, right after this DDL statements.
Sometimes i use this:
select object_name, object_type from all_objects where owner='TOYCOM' and status='INVALID'
Then, I would simply recompile the invalid objects.
For indexes, i do...
alter index <name> rebuild;
BTW, I did try to preview message, and then click on Create Topic, it gave me error..again.

how to play around with NDS dynamic sql and I'm trying to add a column on the fly.Basically the procedure is trying to take a table name, column name, and eventually a data type and adds it to a table.
It works fine without the bind variable for the column name, accepting the table name on the fly.As soon as it tries to use the column name I get an ORA-00904 invalid identifier exception.

We have some tables in our database in which for loading data we have the setup in place to do Exchange partition after data load into staging. Today we did changes to column length to one pair of main and staging table. Post that Exchange partition stop working.

I got the error ORA-01653: unable to extend table <OWNER.TABLE_NAME> by <BYTE> in tablespace <TABLESPACE> in my production database. But I could see 4GB of free space available in the tablespace. But this was resolved after increasing the Tablespace size by 1 more GB. So I wanted to know how I can I reclaim the 4GB space ?
While searching in internet I got few tips like there will be a fragmentation in the tablespace, the free space available in the tablespace may not be a continuous block. To avoid this we need to reorganize the tables using ALTER TABLE <TABLE_NAME> MOVE <TABLESPACE>; command.
But in my tablespace there are huge number of tables exists I cannot do reorganization of all the tables. So I need to know how to identify particularly what are the tables has more fragmentation? so that I can go for reorganizing those tables only.
