Replication Challenge Based On Unique Needs
Feb 7, 2013
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?

I got this error message in my replication environment.
ORA-12012: error on auto execute of job 2182370
ORA-12008: error in materialized view refresh path
ORA-00001: unique constraint (TE.S_TE_MTH_DBASE_SALES_INFO_A_U1) violated
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 189
Materialized view and Base table having only one unique index. There are no referable constraints in my base table. Because source table not refer any other tables.
Even; materialized view log created using rowid because there are no primary key constraints in my base table.When I manually refresh materialized view I got the below error message
ORA-00001: unique constraint (TE.S_TE_MTH_DBASE_SALES_INFO_A_U1) violated
How it's possible? Because there is parent/child relationship in my source table and there is no way to enter duplicate records it's unique index.

I have a table which sees a lot of use for queries
CREATE TABLE CASE_STAGE
(
ID NUMBER(9) NOT NULL,
STAGE_ID NUMBER(9) NOT NULL,
CASE_PHASE_ID NUMBER(9) NOT NULL,
"CURRENT" NUMBER(1) NOT NULL,
--and other columns
)
ID is a primary key
CASE_PHASE_ID is a foreign key
"CURRENT" should only ever have values of 0 or 1. When it has a value of 1 it is unique for that CASE_PHASE_ID
What I have tried that doesn't work is
create unique index case_stage_F_IDX1 on case_stage("CURRENT", case_Phase_id) which gives me
ORA-01452: cannot CREATE UNIQUE INDEX; duplicate keys found
What is the correct syntax, something like ("CURRENT"=1,case_phase_id) seems right but fails with an error about a missing bracket. Do I need to use a CASE statement here?

I have a list sample:
Order#Location VendorName
--------- --------- ------- -------
145646842 MLIQUID02T 368308 JOHNNEISHA
134962284 MLIQUID02T 368308 JERRY
141138899 MLIQUID02T 368308 CARLENA
5078916 MLIQUID02T 368308 DONNA
[code]....
What I'd like to do is run SQL that can create output where I get 2 records from each Location. Example:
Order#Location VendorName
--------- --------- ------- -------
145646842 MLIQUID02T 368308 JOHNNEISHA
134962284 MLIQUID02T 368308 JERRY
13999694 MLIQUID03T 368308 TINA
175439805 MLIQUID03T 368308 RANDI
4801973 MLIQUID05T 368308 DIANA
55907648 MLIQUID05T 368308 DESIREE
Personally, I don't need the top value(s), but it would be nice.I was trying a few routes with rownum, and I can get it to pull 1 set of pairs with a where location= condition, but I can't seem to successfully combine the two.

In my form i have a multi record block which is based on a table in which i am performing insertion, deletion, updation.
My requirement is as below,
While saving a records i want to check distinct value of specific item can not be greater than some value say 2. Then only my records should be saved. I am planning to populate those values in a collection table type and take the distinct values from it. How to populate record values in a collection table type.

TABLE 1 : COSTS
I have a table of Costs. We have Jobs that run and there will be a cost associated with a particular machine.So JobNo 1 may run on Machine A and have a cost of 50 dollars. Although its now shown below JobNO 1 could run on MachineB and so on.
JOBNO MACHINE COST
1 MachineA 50
2 MachineA 70
3 MachineA 100
TABLE 2: OPERATIONS
We have operators (PERSONCODE) run the jobs on the machines. So Job 1 may be run by PERSONCODE 8 (e.g. Tony) and it may run on MachineA or MachineB.Multipe people may run a particular job. The PERSONCODE will be unique to the Job and it is actually unique to the list. A person never works on more than one job.
JOBNO MACHINE PERSONCODE
1 MachineA8
1 MachineA7
1 MachineB6
2 MachineA3
2 MachineA2
2 MachineA1
3 MachineA4
DESIRED RESULT:
I need to assign the COSTs to the OPERATIONS table but only want it to show next to one person (next to the appropriate machine).
DESIRED RESULT:
JOBNO MACHINE PERSONCODE COST
1 MachineA8 50
1 MachineA7
1 MachineB6
2 MachineA3 70
2 MachineA2
2 MachineA1
3 MachineA4 100

Using Oracle 11g, below is the table, partitions, unique and non-unique local index:
CREATE TABLE DOCA( DOCA_ID NUMBER NOT NULL , DOCA_BKG_PAX_ID NUMBER NULL , ROW_PURGE_DATE DATE NULL ,)PARTITION BY RANGE(ROW_PURGE_DATE)INTERVAL(NUMTOYMINTERVAL(1, 'MONTH'))( PARTITION P2007 VALUES LESS THAN (TO_DATE('01/01/2008', 'dd/mm/yyyy')), PARTITION P200801 VALUES LESS THAN (TO_DATE('01/02/2008', 'dd/mm/yyyy')),) TABLESPACE T0; ALTER TABLE DOCA ENABLE ROW MOVEMENT;
CREATE UNIQUE INDEX XPKDOCA ON DOCA( DOCA_ID ASC, ROW_PURGE_DATE ASC)LOCALREVERSE TABLESPACE I0; ALTER TABLE DOCA ADD CONSTRAINT XPKDOCA PRIMARY KEY (DOCA_ID); CREATE INDEX XFKDOCA_DOCA_BKG_PAX_ID ON DOCA( DOCA_BKG_PAX_ID ASC)LOCALREVERSETABLESPACE I0;
I would like to know the difference between the performance of the unique and non-unique local indexes?.

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

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 am using prebuilt MV to perform replication of about 300-400 master tables from one database to another database. I am wondering about the impacts on triggers in general replication.
IS there a general rule to enable/disable a trigger before a refresh.

Is it possible to replicate table data on real time from sql server (2005 32 bit or sql server 2000 32 bit)to oracle 10g running on linux 64 bit? If yes then what are the steps.
It will be one way replication from sql server to oracle. Which option is best sql server dts or Oracle Stream replication to replicate table data.

I need to set up replication between three 10g R2 databases.There will be one main database where the data will flow into two small databases. A little bit of information will flow back from these smaller databases into the main one.
I have been asked to evaluate ODI as an option. Unfortunately I cannot use Golden Gate due to the cost.I've had a play with ODI and it looks like it's all done on a GUI where I would much prefer to be using command line scripts for setup and monitoring.
It also looks like ODI is more geared to integrating data from many different sources but I'm just going from Oracle to Oracle so don't know if it's a bit overkill.
I'm thinking of just looking at CDC which I can set up with scripts and looks to be the basis behind ODI anyway (when it comes to taking data from Oracle) - again. I may even go down the streams route that I have used before.
