we get daily a full dump from our customer. We have to build the differences of tables (deltas) and load them in separate tables.
There some questions, requiremenst and restrictions:
1) Is it possible the merge the dumps ?
2) How to build the differences as the easiest ?
3) The whole process (import, merge, extract) should be run in batch.
4) We have only a solid knowledge and liitle time for doing.
By default the Oracle utility expdp will not guarantee data consistency for particular point in time when the dump was taken.
When importing such dump you can get errors like
CODEORA-39083: Object type REF_CONSTRAINT failed to create with error...
ORA-02298: cannot validate (...) - parent keys not found
To make your Oracle data pump dumps consistent use flashback_scn or flashback_time option.
Example:
CODEexpdp myschema/... DIRECTORY=expdp_dir DUMPFILE=mydb_20110308.dmp logfile=mydb_20110308.log SCHEMAS=myschema FLASHBACK_TIME=\"TO_TIMESTAMP\(TO_CHAR\(SYSDATE,\'YYYY-MM-DD HH24:MI:SS\'\),\'YYYY-MM-DD HH24:MI:SS\'\)\"
have few exp dumps from earlier version of oracle 8i & 9i, now i wanted to import in oracle 11g. how to do or some URLs/Docs to refer ?I have read MOS Doc 132904.1 do from where i can get earlier exp/imp client and how to use on oracle 11g DB server ?
View 2 Replies View Relatedi'm writing a job to export data on a weekly basis and archive those data in-case needed to be re-imported in future, its important that we able to import successfully if ever needed.
can impdp perform checks to see if dumps are valid ?how about old imp?if not, will it be safe enough to rely on the export log file? in another word is it safe to assume its all safe if there is no error or warning in the exp log?
I have two Schemas
DMS_NS_STG_1,DMS_NS_STG_2
Both are having same tables but with diffrent data. I want to write a generic code piece for a table to get that diffrences out, it can be for multiple tables. There will be a DB link between two DB.

what are the main points that these examples are considered cursors? and why are they called explicit and implicit cursor.
explicit
for x in (select * from emp) loop
dbms_output.put_line('emp no: '||x.empno);
end loop;
implicit
select empno
into vEmpno
from empno
where empname = 'SCOTT';
for all we know that these are not clearly defined on the declaration area as cursor.
I am planing to write the web-application which use Oracle DB 11g.I would like to understand what are the differences (specially, performance issues, steps of execution, optimizer possibilities) between calling SQL statements and PL/SQL procedures/functions. Which approach is more appropriate, and why?
Examples:
a) WebApp->Call("select * from employees where department_id = ?", 10) ;
b) WebApp->Call("? := mypackage.get_emp(?)", refCursor, 10);
create package mypackage is
function get_emp(dep_id in number) return sys_refcursor is
begin
open cur for select * from employees where department_id = dep_id;
end;

Requirements: High-concurrency, 100+ db sessions, DB will not be used for business-logic.
we have an issue on a server, where if we insert a value containing foreign characters from SQL+ we see it screwed up from SQLdev, whereas if we do the same insert from SQLdev it's then screwed up in SQL+.
All operations are performed on the DB server itself, SQLdev connection type is TNS and the entry being used is the same as the one used by SQL+.We checked v$nls_parameters and the values contained there are the same from both SQL+ and SQLdev.
We have recently upgraded application (from Oracle Applications 11.5.9 to 12.1.3) and database (from 9.2.0.5.0 to 11.2.0.3.0).Since we are confronting to performances issues, i try to analyse some queries which Explains plans seems strange (in my opinion).Studying one of them i discover the next case (which according to my logic, i can't explain): --
Just bind variable --select *from MTL_MATERIAL_TRANSACTIONS mmtwhere 1 = 1and mmt.INVENTORY_ITEM_ID = :p1and mmt.ORGANIZATION_ID = :p2and mmt.TRANSACTION_REFERENCE = :p3--and mmt.SUBINVENTORY_CODE = :p4 PlanSELECT STATEMENT ALL_ROWS Cost: 5 Bytes: 361 Cardinality: 1 2 TABLE ACCESS BY INDEX ROWID TABLE INV.MTL_MATERIAL_TRANSACTIONS Cost: 5 Bytes: 361 Cardinality: 1 1 INDEX RANGE SCAN INDEX XXSPE.XXSPE_MTL_MATERIAL_TRANSAC_N99 Cost: 3 Cardinality: 2-- Nvl on bind variable --select *from MTL_MATERIAL_TRANSACTIONS mmtwhere 1 = 1and mmt.INVENTORY_ITEM_ID = :p1and

We have the following scenario:
1) We get a daily Oracle 11 Dump
2) We only want to import the current changes in a MySQL database .
For this we need:
a) Is there a tool, script or best practices to get only the differences (delta) ?
b) How to import an Oracle dump or only teh differences into a MySQL database ?
differences of enabling thread as public or private?
lets assume that i have two threads (1, 2) for two instances (1, 2) and each of thread consists of 2 redolog groups - minimum configuration.in case i need add third node i need third thread.
what will be difference if i set this thread as public instead private?
I have an existing view that stores some data. I was asked to create a table based on the columns present in the view. I only copied the table structure from the view.
Now I would need to create a stored procedure that executes the query and stores the data in the table with a snap id and date of snap column. The reason this needs to be done is to show differences over time for historical and trending.
We are trying to use the methods/constructors in the object types and find it more similar to the procedures and functions in the packages. I am wondering how they are different from stored procs and functions and what are the advantages?

e.g. we have

what is the possible leak for us ? Is there any description about the features changed in 10.2 up to 10.2.0.4 in all steps - so that we can check out which functions we do not have.

I am not usre if the error is due to insufficient privileges as we are able to build tabl;e in the system dynamically using the above mentioned command.
I am an absolute neophyte at this. I'm fairly good at SQL, but have not administrated a database before.
I am trying to take a backup from our production database and restore it to a fresh install of Oracle 10.2 on a Windows 2003 server using RMAN - but I am not getting very far. Software versions are all the same. I have access to the manuals, but it seems like every link I follow adds more questions than it answers.
I have gone through the wizard and set up oracle on the new box - that all seemed to go smoothly. In order for this to work, do I need to set up the database with the same DBID as the one in the backup files? Or is there a way to import the data from the backup and have it build the database from those files?
I'm not sure I'm even asking the right questions. Do any of y'all know of a tutorial that would walk me through this process step by step?
We have an requirement to create xml data for entire database (selected tables) which are in hierarchy.Procedure should read node_mapping table having parent and child tables relationship info and build XML Select statement.
Currently it is building SQL statement whenthere are one parent having multiple childrens i.e Dept having emp, emp_act, emp_rsch..but when child node are having childrens then it is not working - it has to repeatedly call this procedure (recursive) and build below given SQL statement.
1. To change procedure to build xml sql statement when there are multiple childrens to child nodes (hierarchy)
2. To format the output in xml data
We are using ORACLE 11G and WINDOWS 7
CREATE TABLE node_mapping
(
NODE_ID NUMBER(5) PRIMARY KEY,
PARENT_NODE VARCHAR2(100),
CHILD_NODE VARCHAR2(100),
PARENT_NODEID VARCHAR2(50),
CHILD_NODEID VARCHAR2(50)
[code]....
We have an requirement to build (XML) Select statement dynamically based on the mapping table (which is in hierarchy format)
I have removed xml keyword, so query will not work. but need procedure which will recursively check mapping table (parent and child table) and build below given select statement.
Example 1:
SELECT dname,
(select ename,
[Code]....
select a default table in oracle as we do in teradata, below is the syntax of teradata.
select 'XXX' as Curr,
'BUS OBJ ' as acq_nm
from (select 1 as one) Union
select 'ALL' as Curr, from (select 1 as one).
so I need the same select in oracle.
I want to build a hierarchy and output it into a sub-report. Since the data in few hierarchy fields exceeds 4000 characters and therefore m getting the ORA-01489 error and the entire report was failing.
So i have used user aggregate function to print the out put. I have also used row_number() to print sequence in query output.
the query that i am using is
SELECT pr_id,
REPLACE (REPLACE (twadmin.STRAGG2(distinct RPAD (to_number(curr), 2, ' ') || ')' || NVL (DECODE (medical, NULL, clinical, medical), 'UNKNOWN') || '###' ||
RPAD (' Causality as per rport ', 50, ' ') || ': ' || reporter || '###' ||
RPAD (' Causality as per report2 ', 50, ' ') || ': ' || hospital || '###' ||
RPAD (' Dechallenge', 50, ' ') || ': '|| dechallenge || '###' ||
RPAD (' Rechallenge', 50, ' ') || ': '|| rechallenge), ',', CHR(10)), '###', CHR (10)) causality
[code]......
the output of the query is
ID Causality
-- ------
3755101 )Blisters (Blister)
Causality as per report1: Probable
Causality as per report2: Possible
Dechallenge : Not Applicable
Rechallenge : Not Applicable
2 )Mental status changes (Mental status changes)
[code].......
but the expected out put is
ID Causality
-- ------
3755101 )Blisters (Blister)
Causality as per report1: Probable
Causality as per report2: Possible
Dechallenge : Not Applicable
Rechallenge : Not Applicable
[code]........
but it should be as
1)
2)
3)
..
..
..
10)
11)
12) for the values in the causality field
I have created a VIEW with a column containing user-defined aggregated values(stores the output in varchar2 data type). Some of the records exceed the maximum limit, for example varchar2(4000). I was suggested a PL/SQL function to check the length and build a string if necessary..

I am facing 2 problems.
1. If the user is in a child application and clicks logout. He is taken to the login screen of the master application (Correct), but once he enters login details, he is returned to the child application (False). I think he should be returned to the Home page of the Master application.
2. If I set Session Timeouts in the Edit Security Attributes of the applications. Then if the user is timed out, he is sent to the login screen of the Master application (Correct). If he then logs in, he is sent the the Home page of the Master application (Correct).
Now if he clicks a link to a child application he is then sent back to the Master application login screen. He then has to login again. He is sent to the Master Home page and everything is then ok.
