Replication :: Reorganize One Table That Related To Several Other Tables
May 15, 2009
I have to reorganize one table that related to several other tables. The reorg is too slow when it runs on this table. I would like to create one image of the table and synch it with the original one in real time. So when I run the reorg, I will use the image table that does not constrained by indexes and other objects. Once the reorg is done, I would like to rename the table. how could I do the replication in real time?
1.Is it necessary to reorganize a table and index after the deletion of records from table ? Because i see some change in table size after table and index reorganization.
2.Will re org table and index improve the database performance ?
Im having a problem with writing an appropriate query for a report in my web application. I need it to extract data from three related tables:
CAR( PK CAR_ID INT NOT NULL, TYPE VARCHAR NOT NULL) REPAIR_CENTER( PK REPAIR_CENTER_ID INT NOT NULL, NAME VARCHAR NOT NULL) [code]...
I need the report to display only available cars. Available cars must have these characteristics:
1. if the CAR_REPAIR table is empty, displays all entries from CAR table... 2. if car has multiple entries in the CAR_REPAIR table display only the latest DATE_RETURN if its lower than todays date (SYSDATE), otherwise don't display that car... 3. don't display cars that are in the CAR_REPAIR table and have DATE_RETURN value of NULL
I would like to reorganize a table inorder of primary key but I'm not sure if I'm expecting the right thing from dbms_redefinition package.
I am working on oracle 9i 9.2.0.8
I have the following table :
SELECT * from SCOTT.TESTTABLE ID REF ---------- ---------- 1 FF 2 BB 3 CC 4 DD 8 EE 6 ZZ 7 YY 5 GG
when I use the CODEexec dbms_redefinition.start_redef_table('SCOTT', 'TESTTABLE', 'TESTTABLE2', 'id id, ref ref', dbms_redefinition.cons_use_pk);
Would the newly created scott.testtable be created in order of primary key (ID) thus a select * from scott.testtable will give me an ordered result?
When I do the test, the table before and after the redefinition is exactly the same so why use the CONS_USE_PK if it doesn't order the table by primary key?
I'm trying to copy a particular set of rows into two tables. I want to change one varchar column to a different string in one of the tables, and create a new unique ID for the copied rows that will match on both tables. I also want that new unique ID to be one digit higer than the current highest unique ID being used across the tables as a whole.
create table testing_query_dtl (query_is number not null, query_type varchar2(20) not null, area_code varchar(4), stn_code varchar2(3)) create table testing_query_hdr (user_name varchar2(30) not null, query_indicator varchar2(1) not null , query_created date not null, query_last_used date not null, query_name varchar2(40) not null , query_is number not null) [code]...
I then used 'mymax+test_seq.nextval' but that won't avoid the unique constraint issue on the table testing_query_hdr and on the table testing_ query_ dtl increments the ID on EVERY row even when I don't want it to.
I want to set up advance replication for 3 master site (multimaster) I created 3 master site named orc1,orc2,orc3 and followed up oracle replication management of API book instruction I created 2 tables(tes1,test2) in hr schema in all 3 master site with the same data. then I created the following steps
1-CONNECT repadmin/repadmin@orc1
2-Create the master group named hr_test_repg
BEGIN DBMS_REPCAT.CREATE_MASTER_REPGROUP( gname => 'hr_test_repg'); END; /
4-add tables test1 and test2 to the group
BEGIN DBMS_REPCAT.CREATE_MASTER_REPOBJECT( gname => 'hr_test_repg', type => 'TABLE', oname => 'test1',
[code]....
I could create DBMS_REPCAT.GENERATE_REPLICATION_SUPPORT for test2 but not for test1 and it produces error
RROR at line 1: RA-23309: object hr.test1 of type TABLE exists RA-06512: at "SYS.DBMS_SYS_ERROR", line 105 RA-06512: at "SYS.DBMS_REPCAT_MAS", line 2552 RA-06512: at "SYS.DBMS_REPCAT", line 562 RA-06512: at line 2
I wanna have a form which has a list box which is including of all table names, by selecting the required table by user all column name and its related data should be retrieve.I have a cursor which give me all field names related to the table by I do not know how can I retrieve table data:
1. How to add item through block base on number of column which selected table has.
2. How to set value of table column in these mentioned column which added in the block.

I have loaded into an Oracle table defined as XMLTYPE. I'm okay with PL-SQL and stored procedures, where I will ultimately do this processing once I get a handle on XML DB querying from an XMLTYPE table.
Based on reading the oracle documentation about XML DB, and more importantly, reading dozens of posts to this forum,I have been successful in loading the XML files into a SQL XMLTYPE table and doing simple queries against that table to retrieve some of its data so that I can then insert that data into other target oracle relational tables.
how to select parent/child data from XMLTYPE tables. I am able to follow the forum examples and can replicate the methods shown on the many example XML contents shown on this forum, but not against the XML that I have to process. I am wondering if my struggle is caused by my lack of knowledge, or by ill-formed XML content supplied to me by the educational vendor.The XML content has structured the XML content nodes in such a way that I do not seem to be able to apply the parent/child sql methods.I have been able to use for other XML examples I have tested against.
My XML file shown below represents High School Transcript data, for which I need to be able to parse out into my own oracle relational tables for that student, his personal info, and his course info, etc. i.e., for our example, which courses he has taken for which High School grade levels. The vendor-supplied XML seems to put the Courses and the High School grade level in "parallel nodes," instead of parent/child nodes, so I am struggling to be able to use SQL to differentiate which course the student took in NinthGrade versus TenthGrade.
-- WHat I would like to determine from a select statement:
LASTNAME GradeLevel COURSETITLE ============================= Smith NinthGrade PHYS ED 101 Smith TenthGrade CALCULUS 201 Smith TenthGrade ZOOLOGY 202
(The data has been simpliied and masked, but is true to the content and is queryable).

I have been given the task to modify our company's Apex from 4.1 to 4.2. The upgrade has been completed; in addition, the current UI, blue and tan has been updated to BlueJay. I have noticed the structure of the page gets shuffled as well as contents within modules. What would be the best way to "re-organize" my pages.
- Would it be easy for me modify the page, if so how do I do this. The settings look identical, so what would I change ? - Do I recreate the entire page from scratch ?
Let's say we have Table - A and we would like to replicate specific row transaction to Table B.
Here are the rows in *Table A* Time: Lets say 15:00
A1 Just Updated @15:00 A2 Just inserted @15:01 A3
B1 - Daily Delete Row -i.e just deleted a while back - Non scheduled process --executed by application @15:02 B2 - B3 - Daily Delete Row - i.e just deleted a while back -- Non Schduled process --executed by application @15:05 B4 - Just recently purged (As part of 180 Day purge ) - Scheduled process executed by operations team @15:10 B5 - Just recently purged (As part of 180 Day purge ) - Scheduled process executed by operations team @15:10 B6 -Just recently purged (As part of 180 Day purge ) - Scheduled process executed by operations team @15:10
Current Data in Table B (Before Replication) @15:00
A1 (without updates) A3 B1 B2 B3 B4 B5 B6
Expected rows in Table B (via replication/snapshot/materialized view / or any other method)
*Replication at 15:30* Table B - Read Only
Expected rows after replication-
A1 -- Newly updated details A2 -- Newly inserted row A3 B1 - Daily delete row is expected to be replicated B2 B3 - Daily delete row is expected to be replicated
***Note row B4 is not expected to be replicated to table B.
Questions:
1) How can we get updates, inserts and daily deletes replicated while ignore large purges? 2) How can large purge changes be reflected in replicated tables as well without deleting daily deletes?
Actually am trying to replicate two db servers from one in hong kong and another in china. when am trying to establish the replication, am getting error 'ORA-04052: error occurred when looking up remote object' like this...
but the same way i have tried in my local network, it is working fine.i have tried schema replication through enterprise manager grid control..
i need to set up a central server with all the master tables and two other local database which will hold the updatable materialized view of the master table...the databases must be synchronized with central server..and user will work on the materialized view database...
I have a scenario like, am having two databases DB1 and DB2 in different locations where I need to replicate some of the tables(around 10 to 15 tables) from DB1 to DB2(i.e. Whenever I update any table in DB1 it has to reflect in DB2.). Both DB1 and DB2 has the same database objects.
(DB version - Oracle 10g Release 10.2.0.4.0).
the steps how this can be done. Can it be done using Materialised View.
I have two schema on the two servers for replication replication is working fine.
i export one schema to another so all the tables exists at both the sites. I am adding objects in the replication group using oracle enterprise manager console.
some of the tables added fine. but some gives me error like.
ORA-23309: object UMESH.PRODUCT_MASTER of type TABLE exists
but with the error in and when generate replication support.
SQL> select status,request,message,oname from dba_repcatlog; STATUS REQUEST -------------- ----------------------------- MESSAGE -------------------------------------------------------------------------------- ONAME ------------------------------ ERROR CREATE_MASTER_REPOBJECT
[code]....
sometimes i got error like
ORA-00942: table or view does not exist
when use CREATE_MASTER_REPOBJECT command to create object at master definition site while the the table exists at the master site.but in the same situation other objects are working fine.
I have a question about the timestamp conflict resolution. let me describe my question with making an example:
I have a table(test1) with 3 columns(a,b,c)
I do also have 3 column groups one for a ,one for b and one for c if i want to use timestamp conflict resolution for b and c should I add 2 column timpstamp1 and stimestamp2 to test1 for each of these columns and define 1 trigger for each of them?
I hesitated because if it is true and for example if we have lots of columns which need timestamp conflict resolution the size of our table become very big.Is it correct?
The database is running in archivelog mode and we have a standby with Maximum performance.There is no RMAN backup..We have noticed there is block corruption while accessing some tables.Now i would like to know are the corrupted blocks also replicated to the physical standby? Is there a way to recover the data from these corrupted blocks without shutting down the database ?
i have a view in a schema of my database 'vw_get_noti_calendar_data' and i want to select some field but it shows an error 'invalid number' and i have observed it but no effect,so where is the error.
my code is---------
SELECT * FROM aepuser.vw_get_noti_calendar_data WHERE TO_DATE (TO_CHAR (event_start_date, 'mm/dd/yyyy'), 'dd/mm/yyyy') BETWEEN TO_DATE (TO_CHAR ('2/28/2012', 'mm/dd/yyyy'), 'dd/mm/yyyy') AND TO_DATE (TO_CHAR ('2/28/2012', 'mm/dd/yyyy'), 'dd/mm/yyyy') AND srnum BETWEEN 5 * 1 + 1 AND 5 * 1 + 5;
I have one 10g database in other country. I want part of their db (selected tables or tablespaces) and import that data to my 10g DB and i want keep to date this data.
I know two ways
1. Data Pump Imp/Emp via FTP, but i can't send only data that have changed (incremental), i must pumping whole selected part of database (i want only new data from their DB, but consistanse with my DB)
2. RMAN etc. or other archivisation tool, i can do incremental achivisation, but can i send files to another instances (my db) and load only that data? Can i do that with SQL*Loader?
For using replication in our production, here i am testing golden gate as replication tool. I tested all scenario in Uni direction ( source to destination). Now have to test replication with DDL support in Bi-Direction. Not getting any Doc for doing replication in Bi-direction( Two Way). If any one has done the same, then please share limitation of replication in Bi-direction through Golden Gate.
I Have configured the replication between two database's at table level. After few miniuts of successful configuration of replication between two db's at table level, I am getting the ORA-00001: unique constraint (%s_PK) violated error in dba_apply_error.
I checked constraint name,type and status on table replicated is same on both source and destination db.
