How does Oracle failsafe work with dataguard

Question: Till now we used two nodes with failsafe and a database server.
We need a solution for the following:
* location 1: the same as above.
* location 2: database server(standby) and maybe another instance(node).
Scenario: The production database at location 1 fails and needs to failover(dataguard?) to the standby db at location 2. The failsafe instances at location 1 still point to the production database(which is down).
Does dataguard point the failsafe instances to location 2. Is there maybe a better solution stategy(keep in mind the costs)?
Or do we need RAC configured with dataguard?
Thanx,
Pim

I was able to run a simple query with ora_* functions using 10g on Windows.
The Oracle OCI calls used by PHP's ora extension still exist in the Oracle 10g libraries
But I cannot recommend this obsolete extension.

How does Oracle client communicate with a database server

Looking to idenify how Oracle Database Client for OpenVMS communicates with database server and whether the protocol used is secure. Realize that it is using whatever the configured network protocol is (ie. tcpip) but is languauge it uses ( ie. SQL, etc..) secured/encrypted and if not what steps can be taken to encypt

How come this values reset to null? What is causing this to reset?Nothing in this has anything to do with the sever. You need to check what the client did on his machine that caused registry to get modified?
How does oracle ODBC works with Oracle database? Need to know all the steps involved?The connectoin from any client is initiated by a client process. This client process is supposed to get a server process to do his work. So if this is done, the client can work now with oracle . Please see the concepts guide for the gory details of the entire process.

How Does the scheduler works with ODI engine

Hi All,
I am new to the ODI and I was going through the documents over the web regarding the scheduling.
Can anyone please let me know how does the Scheduler in ODI is coupled with the ODI engine.
How does the internal scheduler works and how does the external one works. What are the processes the it calls while invoking the scheduler.
Your help will be highly appreciated.
Thanks,
Sumit

Scheduling in ODI is controlled by a special type of ODI agent, strangley called the ODI scheduling agent. This agent is installed as a service and as well as being responsible for all tasks associated with a normal agent is also responsible for managing ODI jobs based on any scheduling information associated with an ODI scenario. All scheduling information is stored in the ODI repository and the scheduler agent reads from this to determine which jobs/scenarios need to be executed and when.

Does Oracle 10g work with Windows 7?

Hi All,
I am using windows 7 ultimate 32 bit edition. does oracle 10g and forms & Reports 10g work with that? plz tell me.

Are you asking whether it is certified (i.e. whether Oracle has tested it and verified that it works)? Or are you asking whether it is an unsupported configuration that happens to work (more or less)?
Oracle hasn't certified any available version of Oracle on Windows 7. It is projecting that 11.2 will be certified on Windows 7. So it's not a supported configuration. Now, it's entirely possible that it could be installed and might work reasonably well. But I'd expect that a few things wouldn't work-- whether those are features you happen to be using, though, is a different question.

How does cc teams work with upgrades (CS3+)?

We had a break in and all our computers were stolen, we are now looking at CC teams.
My question is, how does this work with the upgrade solution? Do we need a serial for each seat we add?
Also what if a person leaves and we delete that seat and add a new seat for a new user, does the discount apply to the new seat?

Does Oracle OSFM work with standard MRP in R12.1?

Hello All,
We are in R12.1.3. I read in the OSFM User Guide that Lot Based Jobs don’t work with ASCP and a comment about OM and Oracle Projects. We are currently using standard MRP. Yesterday i came to know that OSFM will not work with standard MRP. Please let me know if there is a way to make OSFM work with Standard MRP.
We don't have ASCP and are not planning to implement it for this requirement.
Thanks,

Hi,
The static INIT() functions were added to the ORDIMAGE/AUDIO/VIDEO types
in 8.1.7 to make it easier for applications to construct an ORDIMAGE/etc
object. Given a simple table, eg:
CREATE TABLE IMAGES ( ID INTEGER, IMAGE ORDSYS.ORDIMAGE );
In 8.1.7 and later its simply a matter of the following to insert a new row:
INSERT INTO IMAGES VALUES ( 42, ORDSYS.ORDIMAGE.INIT() );
Where ORDSYS.ORDIMAGE.INIT() is simply a static function that returns an
initialized ORDSYS.ORDIMAGE object. Prior to 8.1.7, it was necessary to
use the standard database object type constructor syntax to initialize
an ORDSYS.ORDIMAGE object. For example:
INSERT INTO IMAGES VALUES (
42,
ORDSYS.ORDIMAGE(
ORDSYS.ORDSOURCE( EMPTY_BLOB(), NULL, NULL, NULL, NULL, 0 ),
NULL, NULL, NULL, NULL, NULL, NULL, NULL ) );
Below I've included some PL/SQL functions that you can use with 8.1.6 instead
of having to use the full constructor.
Hope this helps,
Simon
CREATE OR REPLACE FUNCTION ORDIMAGE_INIT RETURN ORDSYS.ORDIMAGE AS
BEGIN
RETURN ORDSYS.ORDIMAGE(
ORDSYS.ORDSOURCE( EMPTY_BLOB(), NULL, NULL, NULL, NULL, 0 ),
NULL, NULL, NULL, NULL, NULL, NULL, NULL );
END;
CREATE OR REPLACE FUNCTION ORDAUDIO_INIT RETURN ORDSYS.ORDAUDIO AS
BEGIN
RETURN ORDSYS.ORDAUDIO(
NULL,
ORDSYS.ORDSOURCE( EMPTY_BLOB(), NULL, NULL, NULL, NULL, 0 ),
NULL, NULL, EMPTY_CLOB(), NULL, NULL, NULL, NULL, NULL, NULL );
END;
CREATE OR REPLACE FUNCTION ORDVIDEO_INIT RETURN ORDSYS.ORDVIDEO AS
BEGIN
RETURN ORDSYS.ORDVIDEO(
NULL,
ORDSYS.ORDSOURCE( EMPTY_BLOB(), NULL, NULL, NULL, NULL, 0 ),
NULL, NULL, EMPTY_CLOB(), NULL, NULL, NULL, NULL, NULL, NULL,
NULL, NULL, NULL );

How does syncing Notes work with Mountain Lion ?

How does syncing Notes with Mountain Lion?

Notes are synched via IMAP. IMAP is a protocol most frequently used by email.
So if you have an iCloud account and have set up a @me.com email address, that's what is used to sync. For Gmail, that can be used as well, though Gmail's IMAP support has to be enabled on their site and their implementation is very nonstandard and can be problematic. Best is to sync notes via iCloud.

How does Oracle Prefetch work?

There are 1000 rows in a table and I fire a "select *" query with a prefetch count of 100. How are the chunks of rows retrieved?
Scenario one: Get first 100 row, wait till cursor rolls over to 101th row, then fetch 100 more rows.
Scenario two: Get first 100 row, irrespective of whether this fetched rows are used or not, fetch the next 100 rows.
I thinks it is scenario one. Any idea? Any links to such documentation.
~Sri

I believe it works more like your first option.
Prefetch tells the OCI layer to grab x rows at a time whenever it has to grab more rows, and to buffer those rows on the client side. When your application requests rows, it can select 1 row at a time (for simplicity of program logic) and get that row from the cache OCI has on the client, rather than incurring the overhead of going to the database for each row. If your application requests rows that have already been fetched by OCI, it will get those rows. If your application requests rows that OCI has not already fetched, OCI will grab x rows from the server and then fulfill your request.
I'm assuming in the above discussion that your application is fetching fewer than x (prefetch size) records, since that's the case 99% of the time. I would assume that if your application fethes 2x records, that would be done in a single database round-trip rather than 2 round-trips, but I'm not sure of that.

How does xalan.jar work with jdk1.3.1 and not work with jdk1.4.1

Hi,
i am using java, xalan, xerces for web development. The environment is jdk1.4.1, xerces.jar, xalan.jar. i am facing problem while transforming xml, xsl. Its giving the following error
java.lang.NoSuchMethodError: org.apache.xalan.xslt.Process.getDefaultLiaison()Ljava/lang/String;
at org.apache.xalan.xslt.XSLTEngineImpl.(XSLTEngineImpl.java:367)
at org.apache.xalan.xslt.XSLTProcessorFactory.getProcessor(XSLTProcessorFactory.java:79)
I tried with jdk1.3.1, xalan.jar, xerces.jar. Its working fine. Can anyone tell me what is the problem with jdk1.4.1 ?
Regards
Ashok

I have the same problem, but the version within SUN seems imcomplete,what version is ?
For example I am using the xsl tag library provided by Apache (I know this now deprecated). In its ApplyTag.java it uses XSLTDataSource this is not in the SUN 1.4 distribution so it falls over. If I add XALAN 1.0.1 it falls over because it on getDefaultLiason() because it starts loading somne classes from rt.jar and some from xalan.jar, how are you meant to override this.

Does oracle Toplink work with oracle VARRAY ??

Does anybody know if oracle Toplink support oracle collections such as VARRAY ?
The Oracle Toplink workbench seems not recognize the Oracle collection type.

The documents [http://otn.oracle.com/docs/products/ias/doc_library/90200doc_otn/toplink.903/b10064/mappingi.htm#1028481] do show some examples but it is unclear when/where in your application code this example code should be placed.
For example, let's say in my Oracle database I have a data type defined as follows:
CREATE TYPE person_name_ty AS OBJECT (
first_name VARCHAR2(30),
last_name VARCHAR2(30)
Now I want to retrieve one of these, say through a stored procedure.
How could this be done? Where in code would it be done?
Thanks

How does order by work with rownum

... I do not see any difference in the outputs for now. You may not, but you can't be sure that you will never see a difference. There may be a difference if you change versions, or if you add more data, or for no apparant reason.
If there's an ORDER BY clause in the main query (as in query 2) then the output is guaranteed to be in that order.
If there is no ORDER BY clause in the main query (as in query 1), then there's no guarantee that the rows will be in any particular order. If Oracle finds it convenient to display the rows in order by one of the columns (for example, rn) then it will do so. You can not count on it always doing the same thing unless there's an ORDER BY clause.
You should check out the analytic ROW_NUMBER fucntion. It's much more useful, and easier to understand, than ROWNUM. (In this particular example, it might not be any simpler, though.)
