Failback and database of CA backup without the tunnels down server?

Hello

We implement DMVPN in a PKI environment for authentication for better security.

I installed a server scenario and the customers of CA in the LABORATORY and it works very well. I am aware that we can save the database on the external media or server.

Now if my main or primary CA server fails, the certificate database will be unavailable until I have manually import those certificates to the router and until then my peerings all will be down (am I right?).

I would like to install 2 routers as CA servers. a 1st acting as main server having a public IP and the 2nd will be backup in case of failure of the primary. But I would like to first of all this as an automated where the backup that failing 1 router will resume immediately without the tunnels down.

Is there a way we can do that? All those put in place this design before? Help, please.

Thank you

Deepak

My design is such that there will not be "pre-shared keys" and only "PKI".

It is the main purpose of a PKI installation... ;-)

So in this case if peers have already established the connection to other peers and the CA server goes down then they will not go down, is that correct?

right. The IPSec peers interested in CA cert has to be registered or the CRL should be checked.

Also what is the configuration command to allow the connections if the CRL can't be loaded?

Crypto ca trustpoint YOUR_TRUSTPOINT

crl revocation checking no

    Hello

    Take a look at the Setup Guide that covers all the different options you have (as there are a some variations).

    http://download.Oracle.com/docs/CD/E14373_01/install.32/e13366/TOC.htm

    But yes, in short, you can have a configuration where there is no external Web server that uses the embedded PL/SQL gateway.

    Hope this helps,

    John.

    Go to: Control Panel, Manager of Devic, adapters to extend your network, click with the right button on your wireless network and click on uninstall.

    Do not put a check in the box: remove the software driver for this device.

    Restart your computer and Windows will install your wireless network.

    If the problem persists, see if your computer manufacturer has an updated driver.

    The duplicate database is restored. It remains only the archivelogs.
    If I try to backup all archivelogs again and to run the double once more,
    The data files already restored are underwritten, or RMAN ALL restart again, RESTORE
    ALL DATA FILES?
    The database has 600 GB. So, if I start again, it's a big problem.

    What can I do to fix this?

    First thing is that you can make two copies because the database is already mounted...
    Why you want to restore again?

    Just start MRP and post if no errors.

  • I lost my router user name and the password and reset does not have without the router

    I haven't used my router wireless of Linksys WRT54G v5 for about 1 1/2 years and he needs now to a new place.

    I put a username and password I forgot for a long time for access to the web according to the security protocols for the modem and I lost the disc for the program control protocol.

    I tried pressing the reset button to clear the modem and it took the WPA Protocol off the power to the modem, so I can use it without any security, but this isn't a good thing.

    Help! How do unlock it so I can get to the security protocols and put back the security on my modem?

    To release your router to your previous settings.

    RESET the router the button is @ the back of it.

    Connect a computer to one of the ports numbered on the router.

  • Need for reports and the analysis down server move to a different server

    I lost my original for RA and re-installed server components on another server, however, when I try to access the workspace site, I get the message * "did not find a server Hyperion Reporting and analysis 'former name of the server running" at the port of 6800. Please check your connection string server and confirm that the server is configured. *

    I re - run the Setup and configuration without result. Is there a configuration file that I have to update somewhere?

    This essentially means that the HSS register always points to the old name of the server for the RA_FRAMEWORK component. You will need to check through the report of registry if there several instance of the RA registered (one with the old server) framework and the other with the new server. If Yes, you can remove the old a registry through the epmsys_registry command line tool and reconfigure with the new server.

    If you need help with the same, if it please raise a SR with Oracle support and should be able to guide you through.

  • Dynamic links - need a solution without the intervention of server

    I am looking for a solution to my shortcuts.  I'm trying to make it dynamic.

    Restriction: I have not and I have no authority to server but I can possibly able to run a script in my Department on each computer.

    I've been looking at things such as mklink and folder redirection, but they seem to do something on the server.

    for example

    I have a file that found in

    \\SERVER01\Data\ENGINEERING SERVICES\NEW Z Drive\Current Products\Subassemblies\Under Review\SUB835 FT128 Ext termination Board\Work Instructions\Document Control - SUB835B - SUB836B.docx


    If the path is passed to (\NEW Z Drive deleted):

    Products\ \\SERVER01\Data\ENGINEERING SERVICES\CurrentSubassemblies\Under Review\SUB835 FT128 Ext termination Board\Work Instructions\Document Control - SUB835B - SUB836B.docx

    the shortcut to the file of control of records - SUB835B - SUB836B.docx would have been lost.

    also if the control of records - SUB835B - SUB836B.docx has been moved to \Subassemblies the link would have also been broken.

  • Creating a database from backups of the production test

    Hello Experts,

    I'm a newbie with a lot new in Oracle. I got the backup inc0 (which includes even backup controlfile) (PROD) production base taken by RMAN and asked to create a new test database (TEST) by using the backup. Can someone please give me the steps on how to restore and create the new database?

    The 10.2.0.4 basic version
    I am aware of the concept of duplicated with RMAN database, but I was asked to do not connect to the target (PROD) database while duplicating. So, I need to create the test database using the prod database backup without being connected to the PROD database. Please guide me.

    Refer
    http://arjudba.blogspot.in/2008/05/restore-and-recover-database-to-new.html
    RMAN restore database from another backup of the different database name

    When you perform a restore using backup of the production database, the db_name would be same on the auxiliary database. Once you restore and recover the database in your test server, you can change the prod db_name to test by recreating the controlfile

  • What is the difference between a backup of the plant and a recovery disk?

    For me a simple question, so I hope a simple answer.

    When I got to my laptop that I created a USB using DBR recovery. It is a little more than 8 GB in size and is appointed SYSRECOVERY.

    At that time there I didn't create a backup of the plant.

    Having recently been read on things related to the re-establishment of a system in case of disk failure hard etc, I saw that Dell has said you must create USB recovery media and a backup of the plant. So, I got a new USB and today created a backup of the plant.

    Looking at it, it is also called SYSRECOVERY and both have exactly the same list of files and folders and have almost the same size.

    So just what is the difference between these 2 options (if any)?

    Or do I now have 2 USBs that will do exactly the same work to restore my laptop computer provided that the factory?

    Case there is no difference, why Dell offer both (and recommend you create both)?

    Thank you

    Technically speaking a recovery media and backup of the plant are the same. But according to the post that you saw at Dell, recovery media is a backup of backup from the factory with the files and applications that you added later. Therefore, to be on the safe side, Dell recommends to create a backup of files and software that have been added later (or is not part of the default configuration).

    The factory backup contains all drivers and software according to the configuration of the PC, and that were pre-installed on your computer.

    Generally, Windows failure, you can use factory backup media to restore the PC without affecting your personal files and software. In the event of hard disk failure, where the hard drive is replaced, recovery media will be useful to restore Windows as well your files and applications.
