Copy the datafiles/redo logs from the Production Server to QA Server

I need to update the QA database on server QA with the Production database on the Production Server. I intend to copy logs files from data/recovery of the Production database to replace the QA database datafiles/recovery logs. Should I stop the Production database before you start copying? If this is not the case, what happens if a Production database data file has been copied to QA and then this Production obtained data file updated before other newspapers of data/recovery files have all been copied to QA?

Thanks for any help.

If you use this technique without closing the database, copied datafile/recovery logs will be incompatible.

You can use the RMAN utility to take backup of the production database and restore it on server QA.

If the database size is small (about 10-20 gb) you can use EXPDP/IMPDB.

    Hi Peter,.

    Thanks for the reply.
    I need make my block dynamic while in a single query, for different packages I can save it in another file with the same name as the package on my local machine.

    What is the problem with the suggestion of Peter? This is not 'dynamic' on this subject?
    To save the code in the files, use utl_file. Inside the loop, open, write, and close a file. If you need help, your zip code and a description of the specific problem.

    It is also possible to use only user_source table to accomplish the task.

    Yes, but it doesn't work for you own schema.
    If you do not use user_source, then you will not need any condition as

  • Package a package on the Production Server

    I use the updated sdk docs documents.  I have a plugin very simple helloworld.  It is composed, as in the example of echo service, she passes a string to a simple java service and receives the back string to display the user interface.

    It all works very well in the environment of the SDK.

    Now, I want to spend this plugin simple helloworld to my system of true vCenter (containing no eclipse, etc.).  Using the SDK - Tutorial.html, step 3 discusses "package and save your solution.  I used eclipse, such as indicated and chose "vSphere SDK Tools-> package vSphere Client plug-ins.  I made sure to make it dependent on my java service.  I looked on all the files, he created for me, and I had to modify the package.XML - plugin to set the < bundlesOrder > to have my load java service before my flex.  I created the zip file and put it on a web server that is accessible.  Then I registered using the #3 'old Client vSphere' method described in the SDK file - Tutorial.html.  I'm on https, so I made sure to include the correct SHA1 fingerprint.

    Then I restarted the WebClient service on the system of vSphere vCenter.  Then I logged.  When my plugin does not appear, I went looking in the newspapers.

    I looked in C:\ProgramData\VMware\vSphere Web Client\Logs\wrapper.log and found errors.  I can paste the full error below, but it starts with this:

    So, he tried to start loading my HelloWorldJava, but failed.  Note that it loads perfectly in the environment of the SDK.  I kept this very simple code.  It does not load in pots of any third party or whatever it is.  The interface has only one method: echo.  So I don't know what I'm missing;  and don't know why it works in the environment of the SDK, but not on the production server.

    I also tried to look in the Tomcat catalina logs, but I don't see anything here that stood out.  In addition, newspapers just VPXD seem to show where I'm logged in, but no additional help for error details.

    Any help is greatly appreciated.

    I have attached a snippit of the wrapper.log containing any errors in this region, if you see something that I missed.  When you get to flex errors, you will see that it fails due to the dependency (as expected) because the java part does not load correctly.

    OK, I misunderstood your original problem.

    The answer is that you can continue to use Java JDK 1.7 as long as you set the compilation option - target 1.6 to generate binary compatible Java 1.6. The Web client server still uses JRE 1.6.

  • Required for the production server?

    Hi all.

    Another stupid question here: we are trying to develop an application that retrieves the position and transfer data from an 11 g database. On the development server where the application is written, everything is local is all hunky-dory. However, when you try to move on toward a development server where the database is not local, emerging problems.

    On the production server, the file Oracle.DataAccess.dll is located in the web service /bin/ directory. Is it enough to allow a web service to access a database of remote, or is the component of Oracle data access install a required on the production server?

    Hello

    Oracle.DataAccess.dll is a piece of ODP.NET - there are managed components, not managed.

    In short, you need customer Oracle and various pieces of ODP.NET for a successful deployment. The client may be either a full or instant client and the version must match the version ODP.NET. Be aware of the 32-bit vs 64-bit issues as well (i.e. develop on 32-bit and deploy it to a 64 bit with 32-bit client server will cause problems if you have not set the 'target platform' correctly when you build your application).

    For future use, the ODP.NET forum is here:

    ODP.NET

  • Local language wrong in the production server.

    I have an app with a few projects with all two locale - Faroese and English. When I run the application on the application by default server on my local machine, it works fine with the locale Faroese, but when I deploy on our production server and try to run it from there the Faroese local doesn´t works more for one of the projects.

    For this project the values that are bound to properties files in my viewcontroller are indicated in Faroese as it should, when the application is run from the production server, but the values that are related to the entity objects and display the properties of the objects files do not work as they should more. English values instead of the Faroe Islands so the English files property are met, but the server does not be able to understand that the Faroes properties existing files or for some reason some prefer the local English for this project so that it can figure out to see other projects in Faroese, so I guess that the error is somewhere in my model project given that the locale Faroese works for my other projects on the production server, but I can´t find out where.

    So now I hope that someone here has experienced something like and can tell me what I need to do to correct this.

    Hello

    I think you've hit a problem with case name of the resource bundle files (* .properties).
    Even windows file system is not case sensitive that your file names MUST be exactly like the bundle Resource Manager is seeking.
    This works also on embedded because the resource bundle files are located directly on the file system.
    When you deploy the EAR/WAR files externally as files are found by the jar/zip finder which is case-sensitive!

    for example: bundlefile_EN.properies is not the same thing as bundlefile_en.properies

    I hope this helps.

  • CFFORM - form validation does not AT ALL during the test on the production server

    So I did all my tests on my local test of Coldfusion server. All form input boxes are validated correctly, with a dialog box popping up when it has not been completed

    When I upload it on the production server, also running ColdFusion 8, it not there no event at all - no dialog boxes, cfform validation etc...

    I use the same client computer to test locally as I test it on the web, and yet I get two different results! Any ideas?

    THE FIRST THING to check in this case, it is that you can connect properly to the/cfide/scripts/folder via the web site on the production server.  This scripts folder is where ColdFusion retains all its javascript, CSS and other client files used in computing, the and other client UI features.  If your browser cannot access these files, these features will not work.

    Rapid tests is just to put the /cfide/scripts/wddx.js in your browser on the production server and see if you get the right javascript file.  If this isn't the case, you must make sure that there is a CFIDE virtual directory configured in your web site and that this directory is readable by users.

  • The Golden Gate system separate from the Production Server configuration

    Hello
    I have two database server Oracle 11 g on Windows System. I want to set Golden Gate on a Windows system separate for replication (one-way) of the source (production) server to the target server of (at rest).

    I am aware of the Golden Gate installation on the source (production) server.

    Please guide.

    Thank you

    To connect to the database when Oracle GoldenGate is running on a different server,
    use a SQL * Net string in the login username parameter. This connection string can then be
    used for connections for all Oracle GoldenGate processes and GGSCI. Do
    certain that SQL * Net is configured to connect to a remote server, including
    the correct entries in a TNSNAMES file. Statement of USER name example:

    In one of our Production Server is a process called "svctimesag.exe" using high CPU. This problem has been detected the day before.

    For immediate solution, we killed the process, but it did not help, then you need to restart our server.

    In the past 24 hours this process has shoot to the top of the CPU twice and you need to restart the server with force.

    Also searched the Internet but found no information. The location of the file on the server is C:\Program Files (x86)\Products\svctimesag\svctimesag.exe
