Physical Standby from Logical Standby

Is it possible this scenario?
Create a physical standby from logical standby and the physical receive archive from logical.
I mean,
Primary (10g production) -> Logical (11gr2 new server 1) -> (Physical 11gr2 new server 2)
The goal of this scenario is a migration with a short downtime.
O.S. aix 6.1
11.2.0.2

Is it possible this scenario?YES

Available webservice/tool that returns the physical qry from logical qry?

Is there any obiee webservice or program that returns the physical query by receiving the logical query as a parameter ?
What we are looking for is to have a "process" that use the logic that bi server has to resolve the reports using the metadata (rpd) to derive the physical query.
It should be like the logic that is behind the "issue direct sql" function. But instead of pasting the logical query into the text box we will be passing it as a parameter in a custom process.
Many thanks,
Georgina

Getting physical path from logical path

Hi,
I am using the FM FILE_GET_NAME to get the physical path for a given logical path which I have specified within the FILE transaction.
The code works fine when I run the program in foreground but it doesn't work when I run it in background.
Can anyone advise on why this is and how I can get this to work correctly in background aswell as foregroud.
The ultimate goal is to be able to poll a directory on the SAP server (which could be windows or unix) and to process the files in there.
Thanks,
Ruby

Thank-you.
I would prefer to to use a default path if possible. The reason I defined a logical path was so that this could be defined outside the program.
Are you saying I cannot use this FM in background at all?
Is there another FM which will do the same thing but will work in background?
What I am trying to do is create a program which will run in the background polling a particular directory and then process the files in this directory if it finds any.
Do you know how I could achieve this using logical paths rather than using hardcoded paths?

Create physical erd from logical erd

I have created the logical ER diagram using designer 6.0.
I would like to know the steps involved in creating the physical ERD (diagram).
I have already done the database transformation sucessfully. I opened the design editor where i can see the relational model with all entities listed. But
i do not see the physical ER model. I was expecting the
Physical ER model in the server model diagram. If i try to open the server model it gives me an option to create a new physical ER diagram. Am i looking in the wrong place ?

In the Design Editor:
Drag the Table names (under Relational Table Definitions) to the empty spot (dark grey) of the GUI on the right side. It will create a new diagram and put the table(s) and any related FK constraint lines on the new diagram.
HTH.
Thanks, George

Regarding assignment of physical path to logical file name

Hi All,
We have created one logical file name and assigned physical path to it in FILE tcode.
IN PATH table also these details got updated with correct logical file name & physical path.
But in my program when i have used FILE_GET_NAME F.M to retrieve physical path from logical file.
Here this F.M is not returning anything.
What is the issue over here.
We are working in ECC 6.0
Can anybody resolve this issue!
Thanks,
Deep.

HD video out from Logic - possible?

I have been trying to find if there is a way to get HD video out to an external monitor from Logic. Tried a Decklink "Intensity" card, wouldn't output HD. I called Aja and Decklink, neither company could tell me if it's possible with any of their products.
Another alternative would be to use a second video card and convert DVI to HDMI (I have two 30" monitors so am already using the two DVI outputs on the main video card), I want to output to a 47" TV monitor for client presentations. In the old days, it was always recommended not to use a second video card with music DAWs because of slowing down the PCI buss - is this still the case with the latest Mac Pro's?

The other thing we've done in the studio when working on films is to use two separate machines. One machine is running ProTools HD and it's the on that plays the video. Use MTC to lock the machines together, you hit play in Logic and hey presto, the ProTools locks to it and plays your video. No reason why you couldn't do this with two machines running Logic. The advantage with using ProTools (HD) is that you can have all of your reels in the one session, one after the other. Then (if your Logic work is properly organized and all of your cues have start points at the correct TC, then you don't even need to change ProTools sessions even once. You can switch between Logic projects (for each music cue) and the ProTools session will happily jump to the right part of the video at all times. This way you eliminate the question of trying to get the one machine to handle everything. Yes it's more of the old-school sync'd up video deck concept, but once you set it up, it's much faster and it works great. You can even route all of your physical outputs from Logic directly into the ProTools inputs and do one-pass (or almost one-pass) striping of all your Logic work to prepare your ProTools sessions for the orchestral sessions. We've done this for a couple of films and it was a very effective way of working.

Creation of logical standby by shipping the redologs from physical standby

Hi all,
I have to create a logical standby database using redo shipping from my PHYSICAL STANDBY while it is in mounted state .Is it really possible to do it??
Please send me any docs regarding this to my mail id ([email protected])
Thanx in advance

It is possible to do what you ask by using cascaded destinations. See the Data Guard Manual (online at OTN) http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14239/cascade_appx.htm#i636046
for the information. This relies on the standby creating and re-transmitting redo log data.
Hope this helps

Creation of logical standby in 9i from physical standby

Hi all,
I want to create logical standby from physical standby in 9i. can anyone send a doc for this

As per the Oracle documents "You create a logical standby database by first creating a physical standby database and then transitioning it to a logical standby database"
Please take a look at the below URL.

Goldengate from physical standby with Active data guard or from logical standby - which is better?

Hi,
We have Oracle 11.2.0.4 and are currently using Active Data Guard on a physical standby. My boss wants me to use Goldengate
to replicate several schema from Oracle to SqlSserver. She doesn't want to touch the Primary, which is in production. Would it be better
to setup a Logical standby for Goldendate to use, in addition to the Physical standby? Or will it be sufficient to use the Physical standby?
The application tables don't all have primary keys. I'm trying to decide if the Logical standby adds another layer of complexity or would
introduce delays in getting the data from Oracle to Sqlserver.
Thanks in advance,

Hi,
In this case I recommend you to use physical standby + Golden gate with ALO mode. You might have sligthly more trouble in logical standby. it means you might have more trouble at Goldengate's extract side.
You said
The application tables don't all have primary keys.
so you have to add keycols on replicat side.
I recommend you to add an index which should consist of keycols columns. it will be necessary for replicat performance.
Best Regards

Drop a datafile from physical standby's control file

Hi,
I am trying to create a physical standby database for my production...
1) I have taken cold backup of my primary database on 18-Nov-2013...
2) I added a datafile on 19-nov-2013 ( 'O:\ORADATA\SFMS\SFMS_DATA4.DBF' )
3) Standby control file was generated on 20-ov-2013 (today) after shutting down and then mounting the primary database...
When i try to recover the newly setup standby using archive files, i am getting the following error (datafile added on 19th Nov is missing)
SQL> recover standby database;

Can i delete the entry for the newly added datafile from the backup control file ?

Hi,
What is your version?
If you added new datafile or created new tablespace, take backup again for restore new created standby database.
If your standby database running well, DG configuration success, then this datafile will create on standby side, too.
Set STANDBY_FILE_MANAGEMENT=AUTO best practice.

Not need any delete datafile from standby side, you must recreate standby database, or you can take RMAN backup and restore to standby side again.

It is not logical, Physical standby must be bit-for-bit same with Primary database.

Logica and Physical standby to the same Primary?

Hi,
I have a primary - standby setup operating in the production. i now have a requirement to configure a Logical standby to the primary server. Can I do that leaving the already existing physical standby intact?
Thanks,
Aswin.

Yes you can have both physical and logical standby from one primary. The logical standby will need to start as a second physical standby.

Logical and Physical Standby Practice

Hello Gurus
I am now attempting to practice Oracle Data Guard and in this direction I understand since 10g we have logical standby server as well as a physical standby server. While I am gathering information and knowledge about the data guard as is and varisous modes and types possible with oracle 10g and 11g in specific, an attempt to upgrade my self and learn these set-ups and understand them in detail.. I come to you for some guidence..
I am referring to Oracle Documentation for these details. At the same time I also approach you to share your experiences .. may be a link apart from the documentation of oracle which you might want to refer me to use as a quick reference.. some thing that a person like me .. fairly new to this set-up understand it and then attempt to come up with one..
This is for my practise and learning purpose.
Sarat.

Logical Standby was already introduced in 9i. It differs from physical standby in the way, the redo protocol, transmitted from the primary, gets used to actualize the standby. With logical standby, you have SQL APPLY - basically, we try to generate the same SQL that was done on the primary from the redo protocol that was written on behalf of that SQL on the primary. That SQL then is done on the OPEN instance at the logical standby.
In case of a physical standby, the redo protocol from the primary is used to do RECOVERY - called REDO APPLY - to actualize the standby.
Since 10g, the sames protection levels can be achieved with logical or physical standby.
Drawback of logical standby: Not all kinds of SQL and all datatypes are supported
Drawback of physical standby: It is mounted (versions before 11g) while being recoverd - or in 11g, REDO APPLY in READ ONLY status is possible but comes with an extra charge (ACTIVE DATA GUARD feature).
If you look on my Blog, I have some examples about creating physical & logical standby DBs
Kind regards

Doubt regarding switchover from logical standby to primary

I am using Oracle 10g databases on Linux environment
I was trying creating a data guard configuration and once I was successfully done I created a logical standby database from the physical standby . Then I was trying to do a switchover .
By mistake I gave the prepare switchover command in the logical standby before executing it in the primary . And then when I gave it in the primary both the status turned to be "PREPARING SWITCHOVER"
In logical standby
SQL> ALTER DATABASE PREPARE TO SWITCHOVER TO PRIMARY;
Database altered.
SQL> SELECT SWITCHOVER_STATUS FROM V$DATABASE;
SWITCHOVER_STATUS
PREPARING SWITCHOVER
In primary
SQL> ALTER DATABASE PREPARE TO SWITCHOVER TO LOGICAL STANDBY;
Database altered.
SQL> select switchover_status from v$database;
SWITCHOVER_STATUS
PREPARING SWITCHOVERNow I am not able to commit any of them to primary or logical standby
In primary
SQL> ALTER DATABASE COMMIT TO SWITCHOVER TO LOGICAL STANDBY;
ALTER DATABASE COMMIT TO SWITCHOVER TO LOGICAL STANDBY
ERROR at line 1:
ORA-16217: prepare to switchover has not completed
ORA-06512: at line 1
In logical standby
SQL> ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY;
ALTER DATABASE commit TO SWITCHOVER TO PRIMARY
ERROR at line 1:
ORA-16109: failed to apply log data from previous primaryLet me know what should be done now ? Is there anyway to solve this issue ?

Can you try using the following first on Primary and then on Standby?
ALTER DATABASE PREPARE TO SWITCHOVER CANCEL;

Logical standby database to physical standby database

I already start my logical standby database and I want to return it again to physical standby database. So what should I do?

>
The "may be" is because I have tested flashback of a physical standby to before resetlogs, but not a logical standby.
>
A physical standby keeps the DBID of the primary - a logical standby does not. That is exactly the problem that restricts the reconversion into physical from logical, and you did not encounter that problem.
>
I haven't used "keep identity" but from what I read it relates to "convert to physical" not "flashback database".
>
Exactly. And that is what the OP wants to do: convert to physical (from logical).
You mentioned that this might be possible with flashback.
Problem: During the conversion from physical to logical, the DBID gets changed unless you specify (in 11g) KEEP IDENTITY. This would make it possible to reconvert into phyiscal from logical.
In short: If there is no solution for the changed DBID of the logical standby in order to flashback it into physical as you suggested, then it is not possible .
When I saw your first answer, I thought that you might have a solution in mind in order to solve that obvious problem. Sorry for having bothered you.
Kind regards
