Replication :: Timestamp For A Table For Conflict Resolution
Aug 25, 2008
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?
I create following update conflict handlers, one after other. These are working correctly, my problem is when i create 2nd it replace first one, and when i create 3rd one it replace 2nd one. I want to put all three in action simultaneously. How can i do this.
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 am working on oracle forms 10g (Windows7 OS). Can we get the image resolution of an image item in oracle forms? Can we resize the image in terms of resolution? I have a requirement where user can upload only 1280x720 size images. Either i have to validate the image resolution and give them a message saying 'Only 1280x720 size images are allowed' or simply i have to convert the image to be upload to 1280x720 size and save in the database.
Actually i am migrating forms from 6i to 10g Here i need to set the window which should be fit in the browser(internet explorer) resolution and it should be compatible for any resolution?
i have tried by changing width and height in formsweb.cfg file but it is not compatible for different resolutions...
We use shared servers for our application connections... when the database starts and randomly grabs a free port number for the dispatchers, we occasionally run into a port conflict - we also have tuxedo and several other processes that start after the database, that have pre-defined ports assigned. So if the dispatcher grabs port 52452 but say the workstation listener is defined to use that same port - once the WSL starts, we have a conflict.
I know we can pre-assign specific ports to the dispatchers; my concern with doing that is that we currently support roughly 150 customers remotely, all using our standard database configuration; many of these have multiple databases per server - in some cases, up to 10-15 databases. So manually managing specific ports on all of these would be tedious, to say the least... especially if some other third party app comes into play that happens to use one of the ports we selected, and we have to change everyone's ports again.
letting Oracle randomly pick a free port within the defined range.
if we add the known ports that are used in applications that start after the databases (the ones we end up in conflict with) to the /etc/services file - will that prevent the dispatchers from using those ports? Does Oracle search the /etc/services file to find used ports, before it assigns new ones out?
All servers are HP-UX, a mix of PA-RISC based and Integrity. Oracle versions are all 10.2.0.3, with a few at 11.2.0.2. Before anyone suggests it, moving away from shared servers is not an option; our application makes new database connects at every query - so thousands of connects / disconnects every hour; the overhead of spawning a new dedicated connection for every one if these is too great, and significantly slows down the application.
For one of our Java applications, the Oracle Client installed in the apps server was 10.2 . One of the SCAN LISTENERs were down in the cluster. When DNS resolves the scan name to that particular SCAN IP where the listener is down, the connection will fail. But , after they upgraded the oracle client to 11.2 , the issue seems to be resolved. It seems that the client is skipping the faulty SCAN IP which doesn't have scan listener running. Are 11.2 and higher Oracle clients intelligent enough to check this ?
We have scheduled some Jobs such as monthly, semi-annually reports using dbms_scheduler. we use 10gR2 software and windows 2003 server. we have a report which supposed to run at 4:00 AM and as soon as the report finishes it sends the report as email to the authorized users. when the scheduler ran the report inside the report it shows as ran at 3:08 AM where they get systimestamp. but when i query the
select last_stat_time, next_run__date from dba_scheduler_jobs where job_name ='TEST';
last_start_time next_run_date 03-DEC-12 04.00.00..223000 AM -04:00 07-JAN-13 04.00.00..200000 AM -04:00
when I query systimestamp from dual on that database from sqlplus: i get the following: systimestamp 04-DEC-12 07.40.16..152000 AM -05:00
I see the difference of -04.00 and -05.00 from both of the queries. i know the systimestamp from dual is correct. how to I fix the scheduler Job to run at the correct time with daylight savings to take effect?
I am trying to produce results in pivot format. I want to know how many entries per day per month. In other words how many entries on a Monday for each month, how many on a Tuesday for each month and so on.
The main problem I have is that the date column in the database uses UNIX time stamp. I have managed to get the results I want for a particular month. This code selects the entries for last month.
What I need is for another column at the start of the results to give the month so I end up with 12 rows, 1 for each month.
I did try to group by PENTERED(which is the unix time stamp column) select pentered, max(decode(pdayno, 1, cnt, null)) Sunday, max(decode(pdayno, 2, cnt, null)) Monday, max(decode(pdayno, 3, cnt, null)) Tuesday, max(decode(pdayno, 4, cnt, null)) Wednesday, [code]......
This gave me thousands of rows as each UNIX time stamp is unique. Is there a way of grouping on UNIX time stamp.
I have one table with a columntype "timestamp" say xyz is the name of the column.Suppose today is 15th Sept So I want to fetch all those records whose value is between 14th Sept 00:00:00 and 14th Sept 23:59:59.
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 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?
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.
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 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.
