How to switch primary role to one of standby DBs without interruption?

We have a primary database with 2 standby databases running. We would like to switch role of primary to one of the standby with other 2 (one is standby and the other was primary) standby without interruption and rebuild? What is the detail procedure for it?
Thanks a lot!

The detailed procedure for anything in Oracle more complex than
SELECT * FROM dualrequires a version number. Since you thought it unimportant to provide that no help is possible.
In this case, in addition to the version number, little things such as:
1. What type of Data Guard implementation? Active? Logical? Snapshot Standby? would be useful information for anyone trying to help you.
2. Is this stand-alone or RAC? Again you provide no information and this is critically important?
3. What is the geographical distance between the primary and the standby?
4. What is the protection mode?
If you are not a student you need to read the Oracle online docs and understand the technology. To ask this question, without providing obviously essential information, indicates you may be a danger to your database: Something I am sure you do not wish to be.

How to Create Primary DB and Physical/Logical Standby DB on the same host?

Now I encounter a issue. I want to create one Primary DB and one Physical standby DB and one Logical standby DB on the same host.
Create this env on the same host aims to test whether we can using EM Patching DP to apply patches on Primary/Physical/Logical DB successfully.
I try to setup this env but fails. I want to know more related issues about create Primary DB /Physical DB/Logical DB on the same host and how to configure between them.
Below steps is my try:
1. Create Primary DB on the /scratch/primary_db
2. Create Physical Db software only on the /scratch/physical_db
3. Create Logical Db software only on the /scratch/logical_db
4. Using EM Wizard to create physical standby database and logical standby database, and these two targets can show up on the "All Targets" Page.
5. But when using EM Patching DP, it fails and the reason is the listener of physical and logical db cannot configured well.
Issues:
So I want to know about how to configure physical db and logical db's listener using EM or manually?
If the listener name of Primary Db is LISTENER and the port is 1521,and the listener.ora is under the /scratch/primary_db/network/admin directory, then how to config physical db and logical db's listener's name and port?

Hi,
As this a test case then you need to create two more listener for each Oracle Home (/scratch/physical_db & /scratch/logical_db) make sure that they have different names and ports.
Then add the new listeners manually using GC?
Try it and let me know

How to allow multiple users login to a MAC PRO without interruption?

I have a mac pro, which runs Yosemite, (2013 module) to be used as a server. However, I have difficult to let multiple users to use the mac simultaneously.
Objective:
    One person uses the mac directly on his desktop, while the others to login remotely though VNC from PC (win 7/Linux).
    The users have their own workspace, and they will not interrupt each other.
What I tried:
    I created two mange accounts on the MAC.
    Account 1 was used to directly login on the mac desktop.
    Account 2 was used to login to the mac from a PC though VNC. (I also tried this from a Centos workstation with the Tiger VNC viewer)
Problem:
When account 2 is login, the location monitor will automatically change to that account as well. Both accounts shared exactly the same screen, mouse & keyboard actions. It is impossible to let multiple users to use the MAC pro simultaneously without interruptions.
If I use "hdiutil attach" to mount a dmg file though SSH with account 2, the folder will automatically show in the local desktop login with account 1.
Question:
I read something about the "Per-user screen sharing". It says, "You can remotely log into a Mac with any user account on that computer and control it, without interrupting someone else who might be using the computer under a different login." Is it possible to do this from a PC or Linux client?
If the problem is simply due to the poor functionality of the build-in VNC service in Yosemite, I appreciate your help to suggest some other decent VNC server for Yosemite. I know the Vine Server (OSXvnc), but I failed to install it on the mac because it is incompatible with the Yosemite.
Does the SSH is supposed to work in this way in OSX? I mean the local account can see the folder mounted by another account though SSH.
If any specific version of Yosemite is required to allow multiple users to access a mac simultaneously? Just as the win 7 professional allow only one user to login in at each time. But with the remote desktop server of windows, multiple users are able to use the same computer at the same time without any problem.
If you familiar with any of the above questions, please help. Any comments and suggestions are appreciated.
I know the best way to get the solution is to direct call the apple support. However, it is really not easy to call them. Because it always results with long waiting time and then the people pick up the phone will transfer my call to an expert who will make me to describe the problem again.
Since I'm not interested in the technique details of all the problems, it is also grateful if you would provide a direct instruction to let me setup the computer for the purpose.
Thanks you very much for your kindly help.

I cannot help with the screen sharing, although I have just tried it with a RealVNC client on an iPad and it seemed to work OK.
However on the disk showing on all users desk tops have you unchecked the "ignore ownership on this volume" check box? You can check the drives permissions with CMD i command.

How to switch Organizer catalog from one hard drive to another?

As far as a little background, i have just finished two high definition projects in Premiere Elements, the last one being 73 projects combined into 6 blu rays. It had completely filled up my 1TB hard drive, so i have purchased an additional 2TB internal hard drive, in hopes of being able to switch all my photoshop to the larger internal hard drive. I am also archiving the old stuff as i finish each project to an external hard drive to free up space.
But i am PETRIFIED at the possibility of trying to move my Elements Catalog because of all the stories i have heard about having the majority of the photos needed to 'reconnect' after switching it to an external hard drive and I assume the same thing will happen to me if i move it to another internal hard drive???????   I have had several computer smart gentleman who have often helped me out when i had a problem and one refused to even venture how to successfully move the catalog and other guy's suggestion is to backup the entire Catalog and then restore it on the new drive.   Steve Grisetti said this morning on his webpage that i should cut and paste the file from one drive to the other but not quite sure how easy that is going to be, because when i have searched out the "move' option, it does not allow me to do anything there. Could that be because i have files that need to be 'reconnected' first before i could accomplish that 'move.'    Steve suggested i come over to this Forum to get some opinions, which is what i have done. That sounds like being more complicated than just cutting and pasting one folder with 16,000 photos. What is the safest way to accomplish this without losing anything, and avoiding the need to 'reconnect' 16,000 files which i am not looking forward to.
So that is my first and foremost question about the Elements Organizer, but i do have some other related problems with the 'reconnect' problem, some of which i have figured out, but not completely. After finally completing these two big projects, my next goal was to clean up my files, get things organized better, and i seem to be finding more and more problems to address. The list of problems decreases with each project but i am still able to find new ones. I am not a computer whiz, and probably shouldn't be trying to accomplish what i am doing with the basic Photoshop programs, something i know the majority of you would be using other more advanced Photoshop programs and much more easily, but i am starting to get this program down, and i don't need more challenges right now.
So i have 3 additional concerns and questions if anyone can help me out to prevent future problems with the next high definition project for Premiere Elements to burn onto blu rays.
1. Because i ran out of space totally on my old internal hard drive, i set up a temporary file on the new drive for the blu ray projects, and I was able to finish the remaining mpeg2s for the final 2 blu rays from Premiere Elements. But when i finished, i started to clean up the files, and realized that the catalog was not recognizing any of the mpeg2 files that i had used to assemble the first 4 blu rays, which was the time i set up the new file on the new internal hard drive, and had copied and pasted my blu ray files. It all seemed to go well, and i was able to finish the final 20 something projects and 2 final mpeg2s for the final blu rays which i prepared and burned on Sony DVD Architect. . But when i went back and was looking at the final mpeg2 files for the previous 4 blu rays, they all needed to be 'reconnected', and i assume it was because the last 2 were on a different drive. And after some effort, i was able to reconnect everything i think successfully. And i am assuming that this will not continue to be a problem if i can get the entire Catalog on the same hard drive. So write that one off to experience.
2. But i hadn't taken the time before doing the blu ray project to label my pictures completely, so the next project i started was renaming the filenames, which quickly presented a new problem, and that made for more 'reconnect' problems again for every picture that i renamed that was used in any of the Premiere Elements Project, so i was back to where i started but even worse off; however, the good news is that my photos were the best organized they ever have been. So all the mpeg2's on the catalog once again asked for 'reconnect' and came to the conclusion that it must mean any name change in the 'filename' also makes it not recognizable. With my first big Premiere Elements project which ended up with 4 blu rays, i made the very big mistake of organizing and moving files in windows, and that is problem #3. So i have come to the conclusion that it doesn't matter, but lots of effort is not obtainable, but i guess i am wondering if it was really worth saving in working condition anyway?? The good news is that the individual photos are fine for the most part, but it is all the mpeg2 files that i combined the original photos into 73 projects, making a mpeg2 of each, then combining about 10-15 of the mpeg2s together and adding music to it, and forming the final mpeg2 which is what i then prepared to burn to blu ray in Sony Architect Studio. The finished product is still present in the Sony Architect software, and i even burned a copy of them again to make sure that was possible, So my gut feeling is just to delete all the mpeg2 files in my organizer, and forget they were ever there! Does that make sense?????    I am not sure that i would ever use them again anyway, but what i am asking is obviously that something as simple as change in the filename screws up the catalog once again????? Yes, i have learned my lesson, and they will all be finalized with the filename ever before i start the next project. Just like with the first project, i learned to stay out of windows all together, and now i only use albums which i found no problems using at all.
3. Last problem is the oldest one, but one i still cannot solve. It was from the first blu ray project when i was doing stupid things like moving folders, and photos from one folder to another to make it better organized. And that was super-organized, and there was absolutely no need to change filenames!!!!! I have two separate problems. Some of the 'reconnects' do not have a picture but the gray square and the ?. I have been able to find most of the files that i had 'displaced' and have recovered them, and knew where they were, and were able to change file names, and it looks like they are back in the catalog. There was also a big file of photos that i found in a file that was the original download file for a given date which is how i NOW download my photos into Photoshop in the first place. But i have not been able to reconnect any of them successfully. They are there and i have renamed them, but the catalog still does not recongize them as being in the Catalog. The other group are photos where the picture shows in the catalog, but there is a ? to reconnect, but i cannot find the photos anywhere. These are of a trip of a once in a life time variety, so i have refused to just press delete, and i thought i had perhaps somehow deleted them all, but i have either found them in another file or the photo is present but i can't rename, i can't reconnect, and for all practical purposes they don't seem to be there. Any suggestions at all? Do i have any other options other than just to delete those whole period of my trip?
I am longwinded, but i wanted to try and give enough background information. The problem seems simple, but i just want to confirm the problems i have run into are for the reason i think they are, and any help on how to successfully move the catalog to the second internal hard drive will be greatly appreciated. Thanks in advance for any comments and or suggestions.
Ron

Thanks for your suggestions, i knew i had overdone it when i wrote the entire story. Just a couple direct questions based on your response!!
Just a couple of questions, i am assuming all the reconnection problems have to be taken care of either by connecting or deleting before the catalog can be moved. Correct?
The reconnect problems i have were not renamed outside of Photoshop, and the renaming does not seem to be an issue except for mpeg2s that are in the catalog that were used to generate the blu rays but i think it was me screwing things up when i didn't know better and was moving folders and photos in folders (Window type) .   Since the blu rays are in the Sony software complete and ready to reburn easily, i assume it would be okay to delete all those that are in the catalog, that need to be reconnected for whatever reason. Plus the individual photos of most of them are just fine. I am talking 376 'reconnect problems' counting all those mpeg2 files which are at least the majority of the 376. Probably would be nice to have, but is there any reason i have to keep them since the photos are okay and the blu rays are burned and still in the Sony Architect program intact?
What i don't understand is the important photos that are worth trying to save seem to be in the proper folder, which is what is stated in properties, but the photo is in the catalog, but with the ? and cannot do anything with it at all, without just going to reconnection, and when i try to identify the folder, it says it is empty, which those are NOT.   If it takes 'forever', then albeit, at least for these few pictures. I really don't want to delete those!
And is it possible to do what my computer tech is telling me that it will all transfer accurately and completely if we backup the entire catalog and then restore it to the new drive?. It seems like after i complete the reconnects one way or another, it might be an easier process that can be completed totally within Element?    Since the catalog is on c drive, i guess i can't do what you suggested buy why?
I kept to those tips you gave me. It seems like an impossibility to save these pictures, but these were from my very first efforts with Premiere Elements and blu rays. Other than the renaming the changing and affecting the Premiere Elements projects in the second one, i have no other problems, and have no recconect problems. So i guess i am moving in the right direction. I just don't need to keep finding ways to make more problems for myself.

How to copy a role from one client to another in a system using the CUA?

Dear all,
I have a question about transporting roles. We have CUA configured on our SAP system. Our development environment contains several clients. Recently I created a role by using PFCG in the development environment named E1D-100. Later there was a need to affect a user by this role but on another client of the development environment named E1D-200.
How can I transport a role from a client of the development environment to another client of the same environment.
While I use SU01 to assign the role, after clicking on "user comparing", I can see that the new created role exists on E1D-100 (the client of the development environment where the role was created), but I see that the role doesn't exist on the other client E1D-200.
How should I proceed?
Thanks in advance,

How can download the roles from one system and upload them into another ??

Do anyone have the solution ..... ......it very important.

Hi,
Visit [Role Maintenance Functions|http://help.sap.com/saphelp_nw04/helpdata/en/e4/15e48efd6c11d296430000e82de14a/content.htm] in section Download/Upload.
To avoid inconsistencies, all roles from which a role is derived are also downloaded. When you download composite roles, all the roles which they contain are also downloaded.
When you upload a role, all role data, including authorization data is uploaded from a file into the SAP system. The user assignments for the role and the generated profiles for the role are exceptions in this case. You must therefore regenerate the authorization profiles after the upload.
Mass Download:
Save several roles on the PC.
You can choose on the selection screen whether you:
Also want to transport the single roles contained in the selected composite roles (Customizing switch ADD_COMPOSITE_ROLES in table SSM_CUST)
Also want to transport the generated profiles for all single roles (PROFILE_TRANSPORT in table PRGN_CUST)
You can define the default setting for both options using the value in the Customizing switch. If you explicitly set a switch to NO, the option in question on the selection screen is not active. Otherwise, it is active.

How To Switch Apps Context In One Session From One Org to Another

Hi,
We are using Oracle APPS 11.5.10 with Database 10g and trying to create receipts using API in a PL/SQL procedure and have registered this procedure a concurrent request. This procedure reads the data from a custom table. The table contains receipt information rows for different orgs. So, in order to create receipts for different orgs we have to run this request multiple times for different orgs. Is it possible for us to run the request once and procedure would change the APPS context at run time reading the respective org from custom table. I hope I have made my point clear.
Waiting for expert opinion.

Kamran
