Synchronize Table Across 2 RAC Clusters?

Is there any way to synchronize a table across 2 RAC clusters? We have 2 RAC clusters setup. Each RAC cluster is setup in its own regional operation center. Not only does it provide us with load balancing capabilities, it also provides us with failover in the event that a regional operations center fails. Depending upon where the application is hosted determines which RAC cluster the application needs to point to. So we would like to synchronize a table that exists on both of the RAC clusters so that in the event of a failover the user information is available on the other RAC cluster.
Any information would be greatly appreciated.

What you are talking about is called advanced replication: (http://download.oracle.com/docs/cd/B14117_01/server.101/b10732/repoverv.htm#REPLN001). I believe RAC offers geographically dispersed clustering as well though. Why not run one cluster but maintain your separate locations?

Joining multiple tables across multiple data sources in MYSQL throws error

Hi all,
I have to join tables across multiples MYSQL databases
eg :
Table T1,T2 from DB1
Table T3 from DB2
Columns from T3 are aggregated ( dimensional column ).
Hence when i query using oracle answers ( say i have columns from T1,T2 and T3 ) , OBIEE tries to a query DB1 by having NULL for columns in T3
It uses cast(NULL as INTEGER ) for columns from T3 . But MYSQL throws an error because "cast(NULL as INTEGER )" is not supported by MYSQL.
I tried executing the query generated by OBIEE manually , if i try giving cast(NULL as SIGNED INTEGER ) , it works.
pasting the query for reference
select distinct D1.c2 as c1,
D1.c1 as c2,
cast(NULL as INTEGER ) as c3
from
(select distinct T87.title_id as c1,
T59.asin as c2
from
print_book_catalog T59 left outer join
title_authority T87 On T59.asin = T87.asin
where ( T59.asin = '0345378911' )
) D1
I am not able to find any config file to set this property ( and use signed integer instead of integer ) . Even DBFeatures.INI does not have relevant information.
Can someobody please help me solve this problem.

Stijn,
Thank you for the article link. That was very helpful! It seems that I had a few things off as you do need the "This source should be combined with other sources at this level." checked. In my two table source columns for DATA_SOURCE I defined a literal ('086496' and '085597' for the other) in the Column Mapping tab. I pasted the following in the Fragmentation content, checking the "This source..." box on the Content tab:
eSIS.SANDBOX4_SCHOOLS.DATA_SOURCE = '086496'
And pasted the following into the WHERE clause, checking "Select distinct values" on the Content tab:
sandbox4."".OBIEE.NWOCA_SCHOOLS.SCHOOL_CODE = VALUEOF(NQ_SESSION."SCHOOL") AND sandbox4."".OBIEE.NWOCA_SCHOOLS.DATA_SOURCE = VALUEOF(NQ_SESSION."GROUP")
This took care of my user's security, utilizing the session variables in the WHERE clause. I am now able to generate reports that only one user can access from one data source and share that same report with another user who can only see data from the other data source.
Many thanks!!!

How to add tables in data clustering after table creation

Hi,
I want to use clustered tables, but the issue is that i have created tables but not
clusters and now i want to make a cluster and add the tables in this cluster.
but doesn't find any solution.
I am using
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14231/clustrs.htm#i1006586
Thanks
Umesh

You have a couple of choices but none of them what you want.
Not knowing version or cluster type or quantity of data or other things my first thought would be to rename the table, create a new one inside the cluster then do an INSERT INTO SELECT * FROM.

Compression on table and on clustered index

Hi all,
if I had a table with a clustered index on it, is it the same to rebuild the table with compression and rebuild the clustered index with compression?
Is this
ALTER TABLE dbo.TABLE_001 REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = ROW, ONLINE=ON)
Equivalent to this?
ALTER INDEX PK_TABLE_001 ON dbo.TABLE_001 REBUILD WITH (DATA_COMPRESSION=ROW, ONLINE=ON)
where PK_TABLE_001 is the clustered index of the table TABLE_001

Andrea,
Cluster index is table itself organized according to clustering key value. So if you apply compression on CI means internally table would be compressed and because cluster index includes all columsn of the table so complete table would be compressed.

Joining tables across databases in OBIEE Physical Layer

I was facing this problem of joining tables across databases in Physical layer of OBIEE admin tool.
I had a requirement to combine two tables from 2 different databases A and B respectively. I had created one database object (OBIEE Object) in the physical layer and I had created two connection pools under that pointing to the required databases. I was able to view the data (right click on the table object --> popup menu option "View Data" ) though I had to go through the "Select connection Pool" window and select the required connection pool. I was able to join the tables and was able to complete the star schema in BMM and bring them up to the presentation layer. Conistency check was also successful. Everything went fine so far.
But when I started building the report, I started getting error whenever I chose the table which was supposed to be queried by using the second connection pool. The error message was something like "table or view does not exist at OCI call OCIStmtExecute". I assume that this was happening because the systm was not able to understand which connection pool to choose (because there were two pools defined under one database object) and by default the server was choosing the first one. If anybody is having a different opinion or definite information about this, kindly update with your reply.
I could resolve this problem after creating a separate database object with a separate connection pool defined under it, which points to the second database. Imported the required table under this database object. (Infact it was reverse. When I re-imported the table, OBIEE Admin tool, by default created its own database object and the connection pool separately for the imported table).
Once this was done then I went ahead as usual by joining the tables across these two different database objects and modelling was already done (ofcourse with a little more tweaking since the mapping had to be redone between BMM and Physical layers). Now I could build the report in the reporting layer without encountering any error.
Appreciate and welcome any further additions/updations/corrections regarding this issue(?).

To be honest, I don't think the transaction is necessary, but the developers put it there anyway. The select statement will put the result cam_status
into a variable, and then depends on its value, it will decide whether to execute the second update statement or not. I still can't upload the screen-shot, because it says it needs to verify my account at first. No clue at all. But it is very simple, just
like:
Clustered Index Update
[analyst_monitor].[IX_Clust_scam_an_name_window]
cost: 100%
By the way, for some reason, I can't find the object based on the associatedObjectId listed in the XML
<keylock hobtid="72057654588604416" dbid="8" objectname="CHAT.dbo.analyst_monitor"
indexname="IX_Clust_scam_an_name_window" id="lock4befe1100" mode="X" associatedObjectId="72057654588604416">
For example:
SELECT * FROM sys.partition WHERE hobt_id = 72057654588604416
This return nothing. Not sure why.

Using one user account table across multiple databases but account used as a foreign key

I want to use one user account table from one database and use it across a couple other databases. The problem is that I want some tables to use the primary key from the user account table as a foreign key to access the data when the user logs in. Is this
the right way of going about it? Do I have to create a user account table in all my databases? What is the best practice to handle this problem? Thanks in advance.

You can use Triggers or using replication.

How to center title text and table across two columns

Hello,
I want to be able to center a table and its title across a two column page. The pages where I want to do this contain text in both columns or text in the left column and graphics in the right. On the same pages as the text and graphics, I'd like to center, across both columns, a table with a title. What is the best way to do this?
If I insert the table in the left column, I can size it to fit over both columns but I can't type directly into the cells that cover the right column (I can type in the cells covering the right column if I Tab to them but it's tedious and doesn't seem right). With the table's title, I've tried using the Across All Columns paragraph setting, but the text stays in the column the paragraph marker is in.
We are using Frame 8 on Windows XP Professional. The Master pages are Right and Left pages that are set up with two columns, both tagged as A with the Autoconnect feature on so that the text flows from the bottom of the left column to the top of the right.
Please let me know what you think.
Thanks,
Tim

Yes, equal-sized columns. No, they're always equal. And that answers
David's question: you're using two frames because you want unequal columns.
Frame's paragraph-level column controls only work on columns made by
dividing a single frame into two or more columns. So you're back to
square one: you need two frames because your columns are unequal; you
need one frame so you can span columns.
Another possibility is that you might set up your document with a
sidehead column, but I hesitate to recommend this because I still can't
quite envision what your layout looks like. Any chance you can post a
PDF somewhere?

Can Apex 4.1.1 see non-Oracle tables across dblinks using gateway?

OS: Windows7 64-bit
APEX: APEX 4.1.1
OracleXE: 11gR2
Oracle ODBC Gateway: 11gR2
Remote DB: Sybase Anywhere 10
=====================
When trying to develop an application (e.g. interactive report), APEX does not see tables from remote database even after public synoym is created in local OracleXE schema that current workspace points to?
I can with no issues -- via APEX SQL Workshop -- run SQL that accesses the remote database tables through the dblink.
Any suggestions?

Apex can work with the views. It does not work well with synonyms. But keep the synonym, since that makes your view indepentent of the name of the DB link.
So the typical recommened structure would be:
<pre>
remote database table
-> access via db link
-> synonym on remote table
-> View on Synonym
-> Apex uses View (Wizards etc.)
</pre>
If using a non oracle DB you might come across problem with certain concepts like ROWIDs. Obviously cyou can't build a form depending on a rowid, when working with a non oracle database. It should work with a normal primary/unique key however.

Synchronize table changes

Hi,
OWB 11g R2, oracle DB 11g
For some reasons.... I have changed my table definitions in the DB level, added few columns and loaded the data using some scripts into this table. I have this table in OWB (old version without these extra columns), is there anyway to synchronize the table definitions from DB to OWB? or I have to do all the changes in OWB again? If I deploy by changing the table in OWB manually then deploy, I guess it does not allow to upgrade, but if I do replace, there is a risk of loosing the data.
Is there any way to do this without loosing the data?
Thanks
Hesh

Hi Hesh,
Yes, this is applicable whether you have created the table through OWB or DB, if you have made the changes for the table at DB level you can reimport the table into OWB and synchronize, Otherwise you need modify the object in OWB manually which will be a cumbersome process if the changes are huge.
Thanks and Regards,

Orphan table header at bottom of page when page breaks a table across multiple pages

Hi all,
I think similar questions have been asked before but I have not found an answer.
Here's the scenario:
I have several dynamic tables in a dynamic form. The layout is flowed, and everything can grow and shrink as needed. That all works.
However, my tables have headers. Occasionally when one of these tables is large and needs to break across multiple pages, there will be just enough room at the bottom of the previous page to show the next table header, but not enough space to show any of the related table rows. So it ends up looking silly, with just an orphaned header at the bottom of one page, and then the table continues on the next.
I have my tables set up so that headers get repeated on subsequent pages, by setting the header row to "repeat row for each data item" on the binding tab. I would like to keep that functionality, but I just want to find a way to avoid these "orphaned" table headers that sometimes appear.
I have tried the "keep with next" option. However, although this does push the rendering of the header to the next page, it seems that according to livecycle the table still officially began on the previous page. Therefore I get a duplicate header because of the "repeat row for each data item" option.
I have also tried having two header rows, one that is set to only be displayed on the initial page, and the other that is set to appear only on subsequent pages (pagination tab). This did not work - I ended up with duplicate table headers.
Can anyone help me?
Thanks!

You shouldn't have "repeat row for each data item" selected for header rows.
You should have "include header row in initial page" and "include header row in subsequent pages" selected on the Pagination tab.
Then using a "keep with next" might work ok.

Updating Database table across multiple SAP systems

Dear All,
I am working on a requirement which is described as follows:
The requirement is to keep a database table in sync across 10 different SAP clients (for production, test systems etc.). So when the database table is modified in source SAP system, it has to be replicated across all the clients and table of other SAP systems.
So the queries from my side are:
1. Whether XI should be used here as a middleware or direct RFC calls can do the updation across the SAP systems?
2. If XI is to be used what would be the recommended approach (ABAP Proxy to ABAP Proxy communication?)
Hope you can recommend me the best options to achieve this.
Thanks & Regards,
Pratik

it depends on what tables are involved/ what type of data/what transactions cause the update.
If you know the table names - then database level replication may be an option u2013 many projects do refresh their QA system with production data for a very real test data. If not, a hard disk level mirroring may have to be considered.
There are other technologies like change pointers in conjunction with distribution model can also be considered - which could trigger idocs that can be sent to the other systems using ALE layer or ALE *** PI/XI

Proc fails with sqlcheck=full accessing tables across a link to non 11g db

I am trying to compile programs that were upgraded from 9i to 11g and having issues whenever I try to compile code that accesses non 11g databases across a link when sqlcheck is anything other then syntax.
If I have a select such as
select distinct a.ID_NUM, b.value1, b.value2, ...
from table_a a, table_b@external_db b
where a.ID_NUM = b.ID_NUM and a.process_name='REPORTS';
This compiler sits and hangs for a few minutes then aborts. This problem occurs in Pro*C, Pro*Cobol as well as Oracle Forms.
The query works fine under sql*plus. The compiler just can't handle it.
A work around under Pro*C is to use sqlcheck=syntax when compiling any code that accesses across a link. However this isn't a good workaround since it won't catch errors such as a typo in a column. This also won't work in forms, but a work around is to convert the selects into a view. However that isn't a good workaround due to the number of queries that would need changing.
Has anyone else seen this issue and found out what needs changed in the Database for this to work. I tried searching Oracle's web site but couldn't find any solution.

I'm not sure why I never thought of searching MetaLink, but thanks for the pointer! It doesn't match my circumstances, however. The Bug smells like a view not being queried in the APEX development tool itself -- i.e. the IDE's coding needs changing, not necessarily those apps created with the IDE.
I'm working on getting you access to my hosted app...

Re: cluster table & table cluster & hr clusters

Hi Friends ,
what is the different b/w cluster tables & table cluster? ,
we have different clusters in HR like PCL1 ... what are these cluster tables or table clusters?.
also we have payroll clusters RT, CRT ... what are these?
could you please give some examples?
thanks &Regards

Different Clusters in HR are
PCL1 - HR work areas
PCL2 - Accounting results (TE, payroll)
PCL3 - Recruitment
PCL4 - Documents
The PCL1 contains the following sub areas:
B1 Time Events PDC
G1 Group Incentive Wages
L1 Individual Incentive Wages
PC Personal Calendar
TE Travel Expenses/Payroll Results
TS Travel Expenses Master Data
TX Infotype Texts
Z1 PDC Interface cost accounting materials management
The database PCL2 contains the following sub areas:
B2 Time Accounting Results
CD Cluster Directory of the CD manager
PS Generated Schemas
PT Text for generated Schemas
RX Payroll Accounting Results/International
Rn Payroll Accounting Results/Country Specific (n= HR country indicator) Therefore US = RU
ZL Personal Work Schedule
The database PCL4 contains the following sub areas:
LA Long document for Master data
LB Long document for Applicant data
SA Short document for Master data
SB Short document for Applicant data
RT and CRT as said by sikindir are result table that will fetch the data from the payroll cluster stores in the PCL2 in RX cluster where X is the country version.
Hope this will clarify you

How to synchronize tables

Hi to all,
In two schemas I have two table Table1 and Table2, very complex and with the same fields and the same records.
It's possibile update Table2 from Table1 or, better synchronize table2 with table1 ?
