How To Persuade Oracle To Update V$RECOVERY_FILE_DEST
Aug 12, 2011
my app/oracle11/diag/rdbms/buidev/buidev/trace/alert_buidev.log ends with
CODEErrors in file /home/oracle11/app/oracle11/diag/rdbms/buidev/buidev/trace/buidev_m000_4587.trc:
ORA-19815: WARNING: db_recovery_file_dest_size of 5000000000 bytes is 99.55% used, and has 22528000 remaining bytes available.
************************************************************************
You have following choices to free up space from recovery area:
1. Consider changing RMAN RETENTION POLICY. If you are using Data Guard,
then consider changing RMAN ARCHIVELOG DELETION POLICY.
[code]....
although I deleted many .arc-files with rm so the disk usage in the recovery area is far below the limit:
CODE[oracle11@gvoracle11 fast_recovery_area]$ pwd
/home/oracle11/app/oracle11/fast_recovery_area
[oracle11@gvoracle11 fast_recovery_area]$ du -ks buidev/ BUIDEV/
9556 buidev/
1212264 BUIDEV/
[oracle11@gvoracle11 fast_recovery_area]$
Inspired by the sugestions in alert_buidev.log and on different web pages I did the following:
CODE[oracle11@gvoracle11 ~]$ ORACLE_SID=buidev rman target=/ nocatalog

That looks like [URL] but my version is 11.2.0.2.0 .How can I persuade Oracle to update V$RECOVERY_FILE_DEST ?

I would like to update an XML element without using the function APPENDCHILDXML or INSERTCHILDXML because they are not available in Oracle 10GR1.
In my database, Oracle XDB is not installed.
The following query fail with the following error : ORA-00904: "INSERTCHILDXML" : identificateur non valide
update scl_profile
set profile_data =
insertChildXML(profile_data,'/exportImportMarcheCriteria','colonnesExport',
XMLType('<colonnesExport>ENTETE_GESTIONNAIRES_AUTORISES</colonnesExport>'))
where profile_xmltype =
'fr.mipih.marches.marche.criteres.ExportImportMarcheCriteria'
and profile_type =
'eMagh2.MRGS.AccesMarche.ListeMarche.Export.OptionsExportImport';
[code]........
If i try to use the package DBMS_XMLDOM, i have the following error :
ORA-06550: Ligne 3, colonne 11 :
PLS-00201: l'identificateur 'DBMS_XMLDOM.DOMDOCUMENT' doit etre declare
ORA-06550: Ligne 3, colonne 11 :
PL/SQL: Item ignored
I think it's because ORACLE XDB component is not installed in my database.

I have performance issue with the bulk update. I have 2 tables one with 21 millions of data and the other table with 2 millions of data.here the requirement is to update the table which is having 21 millions with the other tables data(which is having 2 million records) based on some matching criteria.
The procedure is taking 9 hours to update the table(which is having 21 millions data). I have created required indexes on table also.But the performance is not good.
Here my procedure:
CREATE OR REPLACE PROCEDURE AHM_GKPR.CLAIMS_WITHOUT_PARTITIONS
IS
TYPE T_PL_CO IS TABLE OF VARCHAR2(3) INDEX BY BINARY_INTEGER;
L_PL_CO T_PL_CO;
TYPE T_PL_CD IS TABLE OF VARCHAR2(9) INDEX BY BINARY_INTEGER;
L_PL_CD T_PL_CD;
TYPE T_PL_NB IS TABLE OF VARCHAR2(10) INDEX BY BINARY_INTEGER;
L_PL_NB T_PL_NB;
TYPE T_SE_CD IS TABLE OF VARCHAR2(1) INDEX BY BINARY_INTEGER;
L_SE_CD T_SE_CD;
TYPE T_BIR_DT IS TABLE OF DATE INDEX BY BINARY_INTEGER;

I need to add a new column to a very large table, and update it with 'N'. (this is similar as specifying default 'N'). I'm using Oracle 9i. Which is the best method regarding to speed, to update this column on entire table? The table contains ~30 millions of records. I've read that parallel DML (here UPDATE) does not work on unpartitioned tables. My table is not partitioned. If i specify:
update /*+ full(p) parallel(p,10) */ my_table p set p.my_column = 'N';
This, i think will not speed up the operation on 9i. Our business does not accept to use CREATE TABLE AS SELECT, then renaming table and recreating all indexes and so on.

have one XL sheet Doc that has 2 tabs. One has the list of keywords for deleting the records from Oracle that has the keywords in it. The second one needs the update query. Read the first column in the XL sheet and replace it with the second column value for the records that has the first column value in it.
I never worked in the combination of XL and Oracle.

I am trying to create some PL/SQL that will create a trigger for UPDATES and INSERTS which will update a column on the same row to the system date.
So far I have:
DECLARE
tablename VARCHAR(30) := 'table';
triggername VARCHAR(30) := 'mytrigger_' || tablename;
[Code]....
I have declared the tablename and triggername outside the trigger creation as I need this to be parameterised for a list of tables.
The procedure IsCDCUser just checks it should be updating for this user.
The problem I get is the following error:
Bind Variable "NEW" is NOT DECLARED

This is my working query in ms access...
UPDATE Caxnode AS A INNER JOIN Caxnode AS B ON A.node_alias = B.node_alias SET A.partition_Type = 'LDOM', A.node_mode = 'LOGICAL', A.host_id = b.host_id, A.num_of_proc = b.num_of_proc WHERE (((A.node_mode)='virtual' Or (A.node_mode)='regular') AND ((B.partition_Type)='LDOM'));
This doesn't work in oracle, I googled and read that update doesnt work with inner join in oracle..translate this query to work on oracle?

I have big trouble with some Update query on Oracle 11G.I have a set of tables (5) of identical structures and a view that consists in an UNION ALL of the 5 tables.None of this table contains more than 20 000 rows.Let's call the view V_INTE_NE. Each of the basic table has a PRIMARY KEY defined on 3 NUMBERS(10,0) -> INTE_REF / NE_REF / INSTANCE.
Now, I get 6 rows in another table and I want to update my view from the data of this small table (let's call it SMALL). This table has the 3 columns INTE_REF / NE_REF / INSTANCE.
When I try to join the two tables :
SELECT * FROM T_INTE_NE T2
WHERE EXISTS ( SELECT 1 FROM SMALL T1 WHERE T2.INTE_REF = T1.INTEREF AND T2.NE_REF = T1.NEREF AND T2.INTE_INST = T1.INSTANCE )
I get the 6 lines in 0.037 seconds
When I try to update the view (I have an INSTEAD OF trigger that does nothing (just return for testing even without modifying anything), I execute the following query :
UPDATE T_INTE_NE T2
SET INTE_STATE = -11 WHERE
EXISTS ( SELECT 1 FROM SMALL T1 WHERE T2.INTE_REF = T1.INTEREF AND T2.NE_REF = T1.NEREF AND T2.INTE_INST = T1.INSTANCE )
The 6 rows are updated (at least TRIGGER is called) in 20 seconds.
However, in the execution plan, I can't see where Oracle takes time to achieve the query :
Plan hash value: 907176690
[code]....
Predicate Information (identified by operation id):
2 - access("T2"."INTE_REF"="T1"."INTEREF" AND "T2"."NE_REF"="T1"."NEREF" AND
"T2"."INTE_INST"="T1"."INSTANCE")
Note- dynamic sampling used for this statement (level=2)
Statistics
-----------------------------------------------------------
3 user calls
0 physical read total bytes
0 physical write total bytes
0 spare statistic 3
0 commit cleanout failures: cannot pin
[code]....
I get exactly the same execution plan (when autotrace is ON).Furthermore, if I try to do the same update on each of the basic tables, I get the rows updated instantaneously.

My oracle version is 10g.I want to update a table which has 2 million rows and 20 columns. I want to update 3 columns in my table based on a query output.
Say:-
select decode(col1,'a',col2,col3) up_col1, decode(col5,'Y',20,30)* col6 up_col2, col7 up_col3 from base_tab a, update_tab b where a.key = b.key
I tried the simple update SQL, it hangs and never comeback even after 2 hrs.So I resort to PLSQL to complete my job using bulk collect with limits. Now I am stumbled upon with the Bulk update step.I referred to the BULK Update example given in [URL]...
I gone by 9i approach, I got invalid rowid error. Since the example doesn't uses a join.
I am little bit worried to go by 10g approach given in the example. I have to fetch entire row from my update table. My update table has 5 varchar(1000) fields. Anyway I am not going to affect them in my update. Whether it will occupy memory and again leads to hanging of my procedure.

I have been asked to rewrite the following update statement without using the hint BYPASS_UJVC.

if (l_Record > 0) then
-- since at least 1 loan was found with the old type, process the actual update

I think I am supposed to be using the Merge statement but I am not sure on how to go about it.

I am trying to develop a form consisting of a key block and a single data block. The problem is that the driving table is not the table that needs to be updated.
user wants the following layout:student Advisor
ID# name degree major Concentration ID# name
The driving table (TABLE A) will supply the first 5 fields. The advisor ID comes from (TABLE B).
The user needs to update the adviser ID# field associated with the student ID# field. The form is to be tabular listing all students. I've seen some info on using procedures to insert, delete, update, query and lock tables, but i'm just not sure if that's what is needed.

I have two table and trying to update tableA with data from tableB but gives an error. My TableA has columns - colA,colB,colC,colX and table B has columns - colA,colB,colX. Sample data looks like this:
tableA:
XXYY, local,3/19,48
XXYY,ixc,3/19,24
XXYYlocal,3/20,48
XXYY,local,3/21,48
Table B:
XXYY,local,48
XXYY,ixc,24
PPQQ,local,72
this is the query I wrote
update tableA a
set (a.colX)=(select (b.colX) from tableB b where a.colA=b.colA and a.colB=b.colB);
When i run it gives this error:single row subquery returns more than one row.
tableB has only 1 value for colX for each colA,colB record but tableA has mutiple colA and colB repeated but for all of thsoe in table A i want to update the tableB.colX value for matching colA and colB.

I have a base table (Table A) block with multiple records displayed. I need to track audits to this underlying table in the following way:
If user updates a field in the block I want the pre-changed record's audit fields to be set and I need to create a copy of the record with the changed values. Basically any changes will result in the record being logically deleted, and a copy record created with the newly changed values.
Tried to implement in the block's pre-update trigger which will call a package to directly update Table A then Insert into Table A, then requery the block. Is there a clean and efficient way to do this?

We recently migrated from 9i to 11g.
One UPDATE query runs for 2min and it opens multiple oracle sessions. Almost 40 sessions. Once the UPDATE is done, the sessions close.
When monitoring V$SESSION, found that the newly opened sessions have a PROGRAM value like "oracle@server (P001)"
The UPDATE query is as below. The query works fine, no issue with performance.
SET t1.text =
( SELECT text
FROM table2 t2
WHERE t1.col1 = t2.col1
AND t1.col2 = t2.col2

In the execution plan of STEP-3, against ID-1 the operation RESULT CACHE is shown which shows the result has been retrieved directly from Result cache. Does this mean that Oracle Server has Incrementally Retrieved the resultset?
Because, before the execution of STEP-2, the cache contained only 2 records. Then 1 record was inserted but after STEP-3, a total of 3 records was returned from cache. Does this mean that newly inserted row is retrieved from database and merged to the cached result of STEP-1?
If Oracle server has incrementally retrieved and merged newly inserted record, what mechanism is being used by the Oracle to do so?

This is my query:
UPDATE t_tt_hours a
SET a.sak_request = (
SELECT b.sak_request
FROM t_requests b, co c
[Code]...
The problem I am having is that it is updating all rows even when it is pulling back a null value for b.sak_request. I've tried adding b.sak_request is not null to the select statement like this:
UPDATE t_tt_hours a
SET a.sak_request = (
SELECT b.sak_request
FROM t_requests b, co c
WHERE b.nam_eds_tracking_id = c.id_dir_track_eds
[Code]...
but it doesn't seem to make a difference. The reason I need to do this is that the difference between where it matches with a valid (non-null) value is 396 rows vs. 12,484 rows which is too time consuming to run on my page.

*Cause: A trigger (or a user defined plsql function that is referenced in this statement) attempted to look at (or modify) a table that was in the middle of being modified by the statement which fired it.
*Action: Rewrite the trigger (or function) so it does not read that table.

For triggers, is it possible to do separate actions on insert , update and delete. For example, if insert is the case, do select; if update is the case, do select from another table and so on?
