• question about broker command failover

  Hi guys
  I have a question about switching to the cmd. For example, I have 1 primary database called stdby3 and 2 databases in waiting who are called stdby1 and stdby2. When I made the transition to the cmd to stdby2 waiting for database, why the old principal database stdby3 becomes not a new database of relief once I made a permutation; In addition the new main and backup databases are not open at the end of the transition process

• question about redundancy and failover from one site to tunnel

  First, I create the underside of crypto card,

  crypto IPSec_map 10 card matches the address encrypt-acl
  card crypto IPSec_map 10 set peer 209.165.201.1

  card crypto IPSec_map 10 the transform-set RIGHT value

  card crypto IPSec_map 10 the value reverse-road

  Then I set up a 2nd card statement, corresponding to the same ACL.

  crypto IPSec_map 20 card matches the address encrypt-acl
  card crypto IPSec_map 20 set peer 23.10.10.10

  card crypto IPSec_map 20 set transform-set RIGHT

  card crypto IPSec_map 20 set reverse-road

  My first question is - since Cryptography cards are processed in order, does that mean the first tunnel VPN (map 10) will always be used if its place?

  If so, what happens when the 209.165.201.1 remote peer becomes unreachable? is the tunnel of the 23.10.10.10 peer back automatically?

  What is the best way to reach a VPN site-to-site main and secondary where 209.165.201.1 primary school and 23.10.10.10 is backup and appears only when the primary is down?

  Thank you

  Hello

  As you mentioned that the Cryptography cards are processed in the order.

  If two cryptographic cards have the same "interesting" traffic then the second card encryption is never used (first crypto card is used).

  The best way to get a redundancy is to do the following:

  crypto IPSec_map 10 card matches the address encrypt-acl
  card crypto IPSec_map 10 set peer 209.165.201.1 23.10.10.10

  card crypto IPSec_map 10 the transform-set RIGHT value

  card crypto IPSec_map 10 the value reverse-road

  Note in the example above that you have defined an instance unique card crypto with two counterparts. The first pair will try first and if not answered, the second peer will be used as a backup.

  It will be useful.

• Question about mobile client synchronization

  Hi guys,.

  Is it possible to synchronize a client mobile android to an oracle database in backend without having to create users on the Mobile of Oracle database server? Because in my scenario, mobile users are stored in a table in the back, and new users can be added periodically. I need the ability to sync with their identity papers. Is there a way to do this?

  Thank you.

  Hello

  There are a lot of things you could do for that.

  for example if the users are added to a table, you could define a trigger whenever a new user is registered and enter its information into another table (lets call him NewUsers). Then make a service that watches over this table NewUsers every say 5 mins (?) and if he finds a new user then he will go and add it in oracle lite as a user. You can see the code in the other thread initiated by gambro2.

  If users are added by your handheld, then you can create a web service that runs the code in question gambro2 that adds new users.

  If you perform a synchronization between database olite and another one (maybe an erp) put the controls there.

• Questions about Failver customer and rapid failover

  have some questions about customer and quick Faiolver of Oracle Database HA failover. Before asking these questions, I want to explain my environment. Here are the details.
  
  
  
  -We have two physical locations called "ABC" and "PQR".
  -ABC is the main site.
  -PQR is the backup site.
  -In ABC, we have the database to Oracle RAC (11.2.0.2) with two nodes.
  -In the PQR, we have only one stand-alone server (11.2.0.2) database with ASM. This isn't a RAC.
  -Data Guard has been configured between ABC and PQR and it works as expected.
  -Please note that we have a license for Active Data Guard.
  -We have products of Oracle Identity Management to ABC and PQR and they will use the RAC database as a primary database that is in the CBA.
  -We have not yet set up a Data Guard Broker.
  
  We want to achieve under objectives:
  
  
  Objective 1:
  -------
  
  Whenever primary CARS down completely, standby database becomes a primary database AUTOMATICALLY and it should allow the read/write operation.
  I guess it's called 'Fast Failover'. Please let me know if I'm wrong.
  
  Issues related to the:
  
  -To do this, I need to set up Data Guard Broker so that this standy database becomes primary when CARS go down completely with a power outage, planned or not.
  -Let's say that CARS falls does completely, how long take Data Guard Broker do standby db as primary.
  -What the client application / which is already connected to the CARS.
  -Let's DB standby became as primary and after some time if RAC comes back, keep data automatically becomes the primary role of RAC?
  
  
  Objective 2:
  --------
  
  As I explained above, all products Oracle IDM and applications to speak to the RAC database, what do know only on the RAC database, which is the main. They are not aware of the pending database.
  
  -Whenever a client session is underway with the primary database of CARS if CARS completely falls down, we would like to wait until the client session should get transferred datbase standby without losing session information. However before that happens, standby database should become primary because the client session can perform write operations.
  
  -Whenever a client attempts to connect to the primary CARS and assumes that the cab is completely down, we would like to expect from any client connections should are transferred pending database.
  However before that happens, standby database should become primary because the client session can perform write operations.
  
  According to my knowledge, above scenarios are called "client failver." Please let me know if I'm wrong.
  
  
  
  Issues related to the:
  ----------
  
  1. Please throw some light to reach above features.
  2. According to my understanding, before customer failover happens, fast failover expected has already occurred and ensure should get the switch for the main role. I guess that all this happens thanks to timeout settings. What are those.
  
  
  Could you please help?
  
  Thank you

  I didn't say that clients cannot reconnect automatically when primary fails: I meant that client sessions can generally reconnect and also keep any session state.

  Yes, they can reconnect but only to keep the session state for a SELECT statement. It is also possible with Data Guard, not only in the CARS I wrote: here's a demo with 10 g
  http://uhesse.WordPress.com/2009/08/19/connect-time-failover-transparent-application-failover-for-Data-Guard/.
  What is not possible is to maintain a session state: (INSERT/UPDATE/DELETE) pending transactions must be cancelled.

• Small questions about Dataguard

  Hello

  I have a few questions about Dataguard. I'm new to DG, carry me so for the display of these fundamental questions:

  We plan to install Oracle 12 c to Win 2012 R2 with primary and physical intelligence on different physical servers. We are looking for HA solution, but cannot afford to license CARS. The two primary & Eve are going to be in the same data center connected via a 1 gigabit network. So I have a few questions related to it.

  (a) since both of our primary & Eve is going to be in the same data center with good connectivity. Can I assume that although Data guard is more DR solution, in our case it would be HA solution since we have no network latency.

  (b) is it safe to assume that where primary fails, then the day before can automatically take the role of primary education without any manual intervention, possibly using Dataguard broker?

  (c) so I understand that where primary breaks down, the existing connections transfer automatically from primary to standby db (most recent primary), but how my web based java application will know that more recent connections must be sent to the standby db Server (more recent primary)? I guess net Oracle has a provision to handle this? Who can be automated?

  (d) given that I have only 2 physical servers, can I deploy broker Dataguard on a normal PC (since it is a thin client) assuming the PC is kept in the data center and is online 24/7?

  (e) I was reading about the modes of Protection, account required to our current situation & infrastructure, I choose 'Maximum availability Mode' instead of 'maximum Performance '.

  (f) what is your point of view about Oracle integrated security? I hear too much on Oracle failsafe, because people generally go to a combination of CARS & dataguard for HA? We have a few additional storage that can be shared between the two servers, but I feel with literally no DG network latency can provide us HA.

  Concerning

  Learner

  (a) since both of our main & secondary is going to be in the same data center with good connectivity. Can I assume that although Data guard is more DR solution, in our case it would be HA solution since we have no network latency.

  Well it will not provide the level of HA that is RAC. RAC is a Transparent Application failover. With a physical standby, you need to apply some delay for a failover operation. You can implement the observer that can automate the failover and reduce the time.

  (b) is it safe to assume that where primary fails, then the day before can automatically take the role of primary education without any manual intervention, possibly using Dataguard broker?

  This isn't really the DG broker, but rather the observer you will need to implement. The DG broker automate failover. It will be the observer who "sees" (where its name) that the principal is down and initiate the failover process. To do this, the observer will use the DG broker, so it will be necessary.

  (c) so I understand that where primary breaks down, the existing connections transfer automatically from primary to standby db (most recent primary), but how my web based java application will know that more recent connections must be sent to the standby db Server (more recent primary)? I guess net Oracle has a provision to handle this? Who can be automated?

  You'll want to read on the QuickStart failover. http://www.Oracle.com/technetwork/articles/smiley-fsfo-084973.html

  (d) given that I have only 2 physical servers, can I deploy broker Dataguard on a normal PC (since it is a thin client) assuming the PC is kept in the data center and is online 24/7?

  The DG broker is required to run on the database server. The DG broker will run on the primary and standby. I think that what you're asking really anything is if the observer can run on a PC. Yes it can. However, it is probably not a good idea. A PC will not have the internal hardware redundancy, a server can have. If the PC can fail more often than to a server. And if the gods are bad, it will fail when you most need.

  (e) I was reading about the modes of Protection, account required to our current scenario & infrastructure, I choose 'Maximum availability Mode' instead of 'maximum Performance '.

  Your choice should depend on the amount of data loss is acceptable.

  (f) what is your point of view about Oracle integrated security? I hear too much on Oracle failsafe, because people generally go to a combination of CARS & dataguard for HA? We have a few additional storage that can be shared between the two servers, but I feel with literally no DG network latency can provide us HA.

  Oracle integrated security only works on Windows with a MS Failover Cluster. Real DBAs do not have Oracle on MSFC.

  See you soon,.

• EBS 12.1.3: a few questions about cloning

  Hello
  
  We have EBS 12.1.3 on AIX 7.1.
  
  A few questions about the cloning of level shared environment of application layer non-shared application environment. We followed 'Cloning Oracle Applications V12 with rapid Clone [ID 406982.1]'
  
  Environment (shared application layer) source:
  -Two nodes in the active application and LBS
  -A database of active and a passive database configuration with Oracle Data Guard.
  -Terminate SSL at the load balancer
  -Updated CFP implementation
  
  Environment target (level app not shared):
  -A single node of the application active
  -One data node active
  -Without SSL
  -No PCP
  
  After the cloning was completed, we noticed the following problems in the target system:
  
  (1) home page is not available because application $CONTEXT_FILE layer always contains the endpoint "https" and ssl settings.
  
  Workaround solution:
  
  Change (with text editor) layer Application $CONTEXT_FILE as follows.
  < webentryurlprotocol oa_var = "s_webentryurlprotocol" custom = "yes" > http < / webentryurlprotocol >
  < sslterminator oa_var = "s_enable_sslterminator" > # < / sslterminator >
  < login_page = "s_login_page" custom = 'yes' oa_var > http://myhost.mydomain.com:8000/OA_HTML/AppsLogin < / login_page >
  < externURL oa_var = "s_external_url" custom = "yes" > http://myhost.mydomain.com:8000 < / externURL >
  
  Run the automatic configuration service and application layer.
  
  Is there a better solution and supported for this?
  
  (2) simultaneous managers do not work properly, because they still have old names of node (used in the CFP in the source system). The solution is used:
  
  1. connect to the EBS GUI web and delete all nodes of all concurrent managers.
  2 shutdown application layer. Check that all concurrent managers have been extinguished. If not, kill the process manually
  3. as a user apps run cmclean.sql
  4 restart the application layer
  
  Is there a better solution for this?
  
  (3) database ARCHIVELOG mode nonarchivelog mode changes in the target system. Is anyway to prevent this?
  
  (4) in addition, we would like to make a full clone (app + db levels) of production without closing the application. Is this possible? What would be the best documents to describe it? In Production, we have Oracle Data Guard physical standby installation as per "Note technique Oracle: Business Continuity for Oracle E-Business release 12 Using Oracle 11g Physical Standby Database [1070033.1 ID]. This can be used when executing a clone of warm for the database, right? What application layer? The steps in 406982.1 include AutoConfig in what application level should be running down. Must the application be broken when running "to maintain the Snapshot information?"
  
  (5) one last question (not related to cloning). Oracle Enterprise Manager console webUI has recently stopped working in IE8. For example, https://myhost.mydomain.com:5501 / em gives "cannot display the Page. It was working properly last week. In Firefox, the same link works fine. Any ideas how to solve this problem?
  
  Thanks for your replies in advance.
  
  BR,
  TH

  (1) home page is not available because application $CONTEXT_FILE layer always contains the endpoint "https" and ssl settings.

  Workaround solution:

  Change (with text editor) layer Application $CONTEXT_FILE as follows.
  http
  #
  http://myhost.mydomain.com:8000/OA_HTML/AppsLogin
  http://myhost.mydomain.com:8000

  Run the automatic configuration service and application layer.

  Is there a better solution and supported for this?

  No, you must modify the context manually and run the automatic configuration.

  (2) simultaneous managers do not work properly, because they still have old names of node (used in the CFP in the source system). The solution is used:

  1. connect to the EBS GUI web and delete all nodes of all concurrent managers.
  2 shutdown application layer. Check that all concurrent managers have been extinguished. If not, kill the process manually
  3. as a user apps run cmclean.sql
  4 restart the application layer

  Is there a better solution for this?

  You follow the best approach. You could update the details of the server node if you wish.

  (3) database ARCHIVELOG mode nonarchivelog mode changes in the target system. Is anyway to prevent this?

  By default, the quick Clone will create the target in noarchivelog mode database.

  (4) in addition, we would like to make a full clone (app + db levels) of production without closing the application. Is this possible? What would be the best documents to describe it? In Production, we have Oracle Data Guard physical standby installation as per "Note technique Oracle: Business Continuity for Oracle E-Business release 12 Using Oracle 11g Physical Standby Database [1070033.1 ID]. This can be used when executing a clone of warm for the database, right?

  Fix.

  What application layer? The steps in 406982.1 include AutoConfig in what application level should be running down. Must the application be broken when running "to maintain the Snapshot information?"

  You can copy the files from the application tier node, while demand is rising. And, there is no need to stop the application to run "to maintain the Snapshot information."

  (5) one last question (not related to cloning). Oracle Enterprise Manager console webUI has recently stopped working in IE8. For example, https://myhost.mydomain.com:5501 / em gives "cannot display the Page. It was working properly last week. In Firefox, the same link works fine. Any ideas how to solve this problem?

  If it works from a browser, then it should not be a problem of EM. Have you tried another client and see if it works? Have you changed a setting in your Internet Explorer browser? Please make sure you add the URL of the EM to the list of trusted sites.

  Thank you

• Just a quick question about the appearance of the cluster

  Hello, this is Matthew, just a quick question about the appearance of the cluster

  Is there anyway to rearrange the order of the elements? I know cutting automatic resizing, I could move the items by hand. But if I use the cluster somewhere else, I have to move the items again...

  What I want is of the order of "Mx My Mz Ax Ay Az Temp voltage CS".

  Is there a quicker way to deal with?

  THz so much!

  You can right-click the border of the cluster and choose "arrange control cluster...". "The user interface is not as intuitive as it could be, but it will allow you to reorder items. If you use the cluster in several places, you should make the cluster in a type definition and replace all current uses of the latter with the type definition, so that they all match. They will also update automatically when you make changes to the type definition. Otherwise, you could have a situation where you have multiple groups with the same data types, but with elements in a different order, and your data will be getting a new denominated, when wire you the whole clusters. The data will be in the same order, but given that the item labels are in a different order, you can't get the data you want, when ungroup you by name.

• Question about OWA scripts - how much time do need to run or not at all

  Just a question about OWA on Exchange 2010 scripts. I have a site and unique Exchange Server. I noticed that we have a powershell script scheduled in the Task Scheduler running daily that defines all the mailbox OWA strategy. This policy is defined in the EMC access client/organizational Configuration (EMC) tab.

  My question is... If the policy is already configured in the access client/organizational Configuration tab, should this powershell script run at all?  Not all new users get this strategy by default (since we have only one policy OWA) If you enable Outlook Web access on the mailbox of the user in the appearance of the mailbox tab?  My thought is that the powershell script and the calendar was just a postponement of the old Exchange 2003 for strategies for the OWA...

• A few questions about my new Z5 Compact camera

  A few days ago I bought the Xperia Z5 Compact (and updated the marshmallow) to replace my Z1 Compact and meanwhile read the manual and looked into the camera settings. Now I have 2 questions about the camera.

  (1) according to this manual, it takes an option to 'adjust the color and brightness manually. I rember having seen this option once in the form of 2 sliders, but now I cannot reproduce it more and find more options in the settings. What should I do wrong or overlooking?

  (2) I noticed that I can manually put only iso for resolution of 8 MP or less. When I put a 20 MP resolution, the iso setting is grayed and automatically the value. Is this a normal behavior?

  Thanks in advance for the answers.

  Hi @Rijnton,

  I just tested this on my Xperia X but it runs on Android M, it should be similar to the Z5 Compact (although there may be some differences).

  Color and brightness options may not be available in manual mode, but are for higher Auto and video.

  

  

• a few questions about the Push Service

  Hi all

  Have some questions about a Service of BlackBerry Push.

  (1) when registering for the assessment, it is requested

  Source IP address for shoot - what happens if I have a dynamic IP and I have two servers different one for development and one for the Production environment?

  1. Push is via the BIS-B connection only
  2. Register to access push Eval with RIM. Download the SDK, which includes a sample application for the client side and 3 examples of applications for the side server. Once RIM gives you access to Eval, you'll have an app ID, password and other details. Deploy the provided sample applications and enter your Eval details when prompted. The client-side sample must be deployed on a real device (i.e. not a simulator). There is a catch: many developers (including myself) have reported on this forum that their client-side sample is not able to receive push messages.
  3. I did not look to push on BES, sorry.

  I am fairly new to push myself, feel free to correct me if I'm wrong.
