SQL & PL/SQL :: Loading Data From Source To Target DB Using DBLink
Jul 21, 2010
Source and Target db version : 10.2.0.4.0
Source Os :Cent OS 5.4 and Target OS:Sun OS 5.10
We are loading data from source DB to target DB using dblink.Source db is having 15.4 crore records of number and varchar2 data types.
Using the logic as follows.
insert into table1 as select * from table1@dblinkname[/email];
DB link is working.If I give "select * from scott.REPORT@DBLINK[/email]" in target db alone i could retrieve records.
Actual query:
Create Or replace procedure test_abcd as
begin
Insert into test select *
from scott.REPORT@DBLINK[/email]
dbms_output.put_line('Hello world');
end;
When i give the above query in sqlplus ,it is hanging. When i see the wait events i could find
"Wait Event: SQL*Net more data from dblink"
How to get the above things working.? when checked with network team they says there is no issue in the network. Do we need to modify any database/network level parameter settings.there is no firewall between source and target db.
I have an requirement to load past and future data from different source table to one tgt table.Say now we are in July
Past Data Apr May Jun
Future Data Aug Sep Oct
I HAVE actual sales for past month and present month which is in Table A & expected sales in table B.for every month i have to load 7 months data TARGRT TABLE..
In future the requirement may change to 6 months also. in that case the procedure has to load past 6 month + current month + 6month future so totally 13 month should be loaded.
I need to insert data in Table A from Table B where most of the fields are identical and might some of the fields will be more in Table A.
ex: Table A: a,b,c,d,e,f Table B: a.b,c,g,h
How to insert this using user_tab_columns in cursor and if I am giving the i/P as my table names . This needs to be configurable and reusable rather i mention all the fields in my logic.
While i am trying to execute this proc,i am facing source does not have a runnable target issue.
CREATE OR REPLACE PROCEDURE GET_CHILDS_SUB ( nid IN VARCHAR2 ) AS n varchar2; CURSOR cur is SELECT node_id FROM test_tbl WHERE parent_id = nid; BEGIN [code]....
We have a requirement to archive and purge the tables dynamically based on the control table input. For that we have to design a control table to gather the necessary information and passed to generate the queries.
I have designed the table as below.But in this case I am not able to handle the parent and child relation ship.
Suppose one table needs to be archived and purged and that table is parent table and it is having 2 child tables, so first required data will be inserted into target table and delete from source parent and child tables. so before deleting from parent we have to delete data from all 2 child tables.
Suppose one table needs to be purged and that table is parent table and it is having 5 child tables, so before deleting from parent we have to delete data from all 5 child tables.
To handle this scenario how can I design my control table.
For archive and purge the query like this. INSERT INTO towner_name.ttable_name (SELECT * FROM sowner_name.stable_name WHERE condition_column<=(sysdate-30)); DELETE FROM sowner_name.stable_name WHERE condition_column<=(sysdate-30);
for purge the quey is like this. DELETE FROM sowner_name.stable_name WHERE condition_column<=(sysdate-30);
This is my control table and I have 300 tables list to archive and purge.
CID SOWNER_NAME STABLE_NAME TOWNER_NAME TTABLE_NAME CONDITION_COLUMN PERIOD UNIT TYPE 1 wedb_au OFFER_HEADER wedb_au OFFER_HEADER LAST_DATE 30 D A 1 wedb_sa OFFER_CUSTOMER wedb_sa OFFER_CUSTOMER LAST_DATE 60 D A 1 wedb_au OFFER_SERVICE LAST_DATE 1 Y P 1 wedb_us OFFER_CUSTOMER LAST_DATE 90 D P 1 wedb_cn OFFER_CARDS UPDATE_DT 2 Y P 2 wedb_au ORDER_HEAD wedb_au ORDER_HEAD LAST_DATE 120 D A 2 wedb_us ORDER_CUSTOMER wedb_us ORDER_CUSTOMER LAST_DATE 150 D A 2 wedb_sa ORDER_HEAD wedb_sa ORDER_HEAD CREATION_DT 1 Y A 3 wedb_us DELIVERY_HEAD wedb_us DELIVERY_HEAD UPDATE_DT 50 D A 3 wedb_au DELIVERY_CARDS wedb_au DELIVERY_CARDS UPDATE_DT 200 D A 3 wedb_au DELIVERY_SERVICE wedb_au DELIVERY_SERVICE LAST_DT 100 D A
WHERE TYPE=P means insert and delete TYPE=A means only delete
wedb_au.OFFER_HEADER is Parent Table. child tables for wedb_au.OFFER_HEADER are wedb_au.OFFER_SERVICE,wedb_au.OFFER_BODY,wedb_au.OFFER_EMAIL,OFFER_TAX. wedb_au.OFFER_SERVICE is child table and parent for this table is wedb_au.OFFER_HEADER wedb_sa.OFFER_CUSTOMER Stand alone table no relationship wedb_us.OFFER_CUSTOMER Stand alone table no relationship [code].......
I currently try to transfer a partition of a table from a source to a target DB. For first test purposes I take both SYS users to avaoid privilege problems. I created below procedure from code fragments out of the net.The partition CSS_201001 from table CTRL_SETTLED_SHIPMENTS shall be transferred (I tried both with already existing partition and non existing on target destination), but I always get the following error at DBMS_DATAPUMP.OPEN:
Exception breakpoint occurred at line -1 of DBMS_SYS_ERROR.pls. $Oracle.EXCEPTION_ORA_39001: ORA-39001: invalid argument value ORA-06512: at "SYS.DBMS_SYS_ERROR", line 79 ORA-06512: at "SYS.DBMS_DATAPUMP", line 3043 ORA-06512: at "SYS.DBMS_DATAPUMP", line 4769 ORA-06512: at "SYS.TEST_DP", line 20 ORA-06512: at line 2

I am trying to insert records into target table from three source tables by using function in a package and I am getting error as follows.

I am trying to update records in the target table based on the records coming in from source. For instance, if the incoming record is present in the target table I would update them in the target else I would simply insert. I have over one million records in my source while my target has 46 million records. The target table is partitioned based on calendar key. I implement this whole logic using Informatica. Looking at the informatica session log I find that the informatica code is perfectly fine but its in the update part it takes long time (more than 5 days to update one million records). find the TARGET TABLE query and the UPDATE query as below.
TARGET TABLE: CREATE TABLE OPERATIONS.DENIAL_REGRET_FACT ( CALENDAR_KEY INTEGER NOT NULL, DAY_TIME_KEY INTEGER NOT NULL, SITE_KEY NUMBER NOT NULL, RESERVATION_AGENT_KEY INTEGER NOT NULL, LOSS_CODE VARCHAR2(30) NOT NULL, PROP_ID VARCHAR2(5) NOT NULL, [code].....
I'm trying to add edmx file in my project for first time. I want to choose the oracle provider ODP.net but cannot find Oracle in the data source list. I have oracle 11g installed , odp and odt installed and can access it from the solution as well. I saw the Oracle listed under data source when I tried to connect the solution to the database through server explorer. The solution is connected to Oracle database through ODP.
I just created a dblink from our Oracle 9i database to a SQL Server 2008 R2 Server using oracle heterogeneous services. The dblink seems to be OK and I can query the remote SQL Server database but I only get results for numeric columns.
Say the remote SQL Server table was created like:
CREATE TABLE [MITLOC] ( [MLCONO] [numeric](3, 0) NOT NULL, [MLWHLO] [nchar](3) NOT NULL, [MLITNO] [nchar](15) NOT NULL, [MLWHSL] [nchar](10) NOT NULL, [MLBANO] [nvarchar](20) NOT NULL, [MLCAMU] [nvarchar](20) NOT NULL, [MLFACI] [nchar](3) NOT NULL, [MLWHLT] [nchar](2) NOT NULL, [MLSTQT] [numeric](15, 6) NOT NULL)
The remote dblink is named after M3PREP.
Then if I run:
CODEselect MLCONO, MLSTQT from MITLOC@M3PREP => this works OK and I get the two columns.
If I run:
CODEselect * from MITLOC@M3PREP => I get the same results as in the previous query and all nchar, nvarchar type columns are missing, I only get the same two columns.
If I run:
CODEselect MLCONO, MLWHLO from MITLOC@M3PREP=> I get ORA-00904 - the column name entered is either missing or invalid.
I set up my .ora init file like this, I suspect there is something missing here, is it related to the NLS_LANG or so?
I am inserting XMLTYPE data using DBLINK I am getting the following error.
INSERT INTO APSP.SALES_HISTORY@APSP_LINK SELECT * FROM KMBS.SALES_HISTORY
ORA-22804: remote operations not permitted on object tables or user-defined type columns

We are accessing data from the server ADM.WORLD by using DBLINK.We got the following error.
PL/SQL: ORA-04052: error occurred when looking up remote object sysadm.PS_HP_INC_ELIG_VW@ADM.WORLD ORA-00604: error occurred at recursive SQL level 1 ORA-28000: the account is locked ORA-02063: preceding line from ADM
For that we checked in the server ADM.WORLD for the account the account is showing locked .After that we successfully accessed the object sysadm.PS_HP_INC_ELIG_VW@ADM.WORLD.
For next day also the account is locked.Why the account is frequently locking.
I have database A and B , we are strictly restricted to not to create any DB links between these database. In database A based on complex logic we in a stored procedure we populate the data to table type..now dot net will take this table type data and insert the same in database B.
Question here :
1.When we try to bulk collect all the data into table type , i am getting error operand exceeds limit, but it is mandate to put all data in one short to table type as dot net will take that and insert into B database. 2.Is there any good logical method to achieve this in a simple way.
I have a horrible problem with EBS (actually, all problems with EBS are horrible) and I think I am stuck because of my ignorance of Forms. if I use terms that are not correct in the Forms world. The form consists of a number of named "blocks" and each block consists of a number of named "fields", not all of which are visible. I need to find the source of the data values in one of these fields. I have searched every table for a column of that name, also all the views and stored PL/SQL that I think might be relevant, but I can no find no mention of a column or variable with the same name as the field. The name does not get a hit in the online EBS tech ref manual, and only two ancient and irrelevant hits in MOS.
My question is: What are the possible sources of data for a field in a form? Have I missed any?
When I create a data block based on a table using Data Block Wizard, the block's Query Data Source Columns property is automatically populated with column definition entries corresponding to the columns of the base table.
I tried making changes to these entries, for example by changing the data types to wrong data types or even deleting them, and I found that those changes had no effect on the block at all. The form was still working as I wanted.
What is exactly the role of the block's Query Data Source Columns property.
The F1 key help says "The Query Data Source Columns property is valid only when the Query Data Source Type property is set to Table, Sub-query, or Procedure". So, explain in each context of Query Data Source Type.
I have 1M Records coming from an External Data source as a Flat File (using ETL). Now I need only Yesterday's data only to load in my Database Table.
this can be done using Bulk Load and Filter.
write the CODE.
Second Part:-
Hint: if I need to update only those records been updated Say the Address1 field is updated. So this records need to update in my Master Customer Table.
If I have many fields in table and any records that are modified (coming to me from External Datasource as a Flat file) how to identify and update that record in my Master Customer Table?
I want to replicate single table data/modification from source db to destination DB.procedure or steps how to create replication between source and dest db for single table.
I created a standby database yesterday and everything is working correctly. I need to make some tweaks, however, and one of those is the directory that the standby database expects the archivelogs to be.
I found that the archivelogs were being shipped to $ORACLE_HOME/dbs and named arch*.arc. Interestingly a log switch ships the archivelog minus the "arch" at the front and all archivelogs now do not have that format. I moved the archivelogs to the correct location and renamed them. I have been able to set the correct location using standby_archive_dest and can see that the archivelogs are shipped to there.
Also, v$archived_log shows the correct path and filename. The problem I have is that when I come to apply the archivelogs it still seems to think that they should be in $ORACLE_HOME/dbs and named with "arch" at the front. what parameter I need to change to tell oracle the correct path and filename to use when applying the archivelogs?
I have requirement as follows. I need to load the data to the target table on every Saturday. My source file consists of data of several sates. For every week i have to load one particular state data to target table. If first week I loaded AP data, then second week on Saturday karnatak, etc.
Provide code also how can i schedule the data load with every Saturday with different state column values automatically.
We are getting the below error frequently from the application while doing insertion/dataloading to a table. The mentioned error is in the Primary key index
Error: 'ORA-01502: index 'INDEX_NAME' or partition of such index is in unusable state'.
I set the value SKIP_UNUSABLE_INDEXES = TRUE using the command 'ALTER SYSTEM SET SKIP_UNUSABLE_INDEXES = TRUE' to avoid this. Again we are getting the same error and Every time Iam rebuilding('alter index INDEX_NAME rebuild') the index and doing the DML Operation.
We have requirement such that whenever stored procedure is executed, their resultant records has to be stored in excel file ( Just like an reports ).No third party tool or reporting tools are used.
is there any option in oracle (Stored procedure or built in packages ) which can create excel file with the resultant records.
I have a requirement like, I received .dat files and placed in my local directory and there is a process/method where this data which is there in .dat file will insert into my oracle external tables?Any link of the example with clear steps?
I was trying to load data from XML files to an Oracle database table.I followed these below steps to load that file data into a table. Created XML_DIR1 as oracle directory where i have kept all XML files.
Create table import_rpt_xml of xmltypexmltype store as binary xml; insert into import_rpt_xmlvalues (xmltype (bfilename('XML_DIR1','I-Yamanouchi-20040525-501.xml'),nls_charset_id('AL32UTF8')));
This insert shows below error: Error starting at line 80 in command:insert into import_rpt_xmlvalues(xmltype(bfilename('XML_DIR1', 'I-Yamanouchi-20040525-501.SGM'), nls_charset_id('AL32UTF8')))

this to deal with japanese characters in XML. I don't want to miss those characters. My databse NLS_CHARACTERSET is 'AL32UTF8'.
Is it Possible doing SQL LOAD into Varray table having two inner objects.
find the structure of the table and its types for your reference
CREATE OR REPLACE TYPE OB_TEST_INFO AS OBJECT ( AGE NUMBER ( 3 ), NAME VARCHAR2 ( 14 ) ); /
CREATE OR REPLACE TYPE OB_TEST_INFO_VARRAY AS VARRAY( 400 ) OF OB_TEST_INFO ; /
