Late Replication

Is it possible to have a late replication of primary database to secondary database using data gaurd?
Say for example, my primary database get refreshed every 3 days i.e drops all the tables and recreates them and repopulates them.
This takes roughly another 2 days.
During this time I need the secondary stand by database to be up and running so that reports can be generated from the previous data.
Its ok to have a 2-3 days lag.
As soon as the refresh process in primary database is complete, we can start the data gaurd and the secondary database also gets refreshed with the primary database i.e. the all tables get dropped and recreated and re-populated.
Is this feasible/possible?

Hello;
feasible = Might consider something else. You don't need a standby, you need a point in time copy.
I might just clone the Primary every so often using RMAN instead.
Example
http://www.visi.com/~mseberg/rman/restore_database_without_catalog.html
With this method all you have to do is shutdown the remote database and have an INIT for its RMAN clone. RMAN will replace everything for you.
possible = Yes as long as you can keep all that archive around. DEFER would work.

  • ISE PSN node won't join cluster

    Hi All,
    Has anyone seen an issue where a PSN can't join the cluster ?
    We join PSN Node
    -Node is registered sucessfully (sync in progress)
    - 1hr later - Replication to node failed.
    - Replication Sync failed due to Secondary Database is down
    I have a customer where admin node and PSN are seperated by firewall.
    We allow in both directions
    Admin <--> PSN
    ICMP
    HTTPS
    1521
    Firewall not showing drops.
    DNS and NTP are ok.
    Current topology is 1 PSN, 1 Admin node.
    Works fine in our test lab, but not customers environmnet.
    Cheers
    Peter.

    You will probably need more stuff opened between the PSN and the network but your rules between Admin and PSN. You might wanna add syslog udp 20514 as well.
    Also, what type of FW are you using? If ASA what happens if you run packet tracer and/or packet capture? Is the flow allowed through and do you see the packets in the capture
    Last but not the least, can you confirm that the DB service is running on the secondary node? From CLI run "show application status ise" If is not either restart the node or just issue "application start ise"
    Thank you for rating!

  • 2008 R2 AD ... Specified replication partner, can I change this later during initial replication

    Hello - Healthy single forest, single domain with 100+ DC's.  Today, added new DC to the forest/domain and selected another DC in it's same site as it's replication partner during dcpromo, initial replication.  Turns out this other DC is in the
    same site, but in an OLD building that we are getting rid of and the link between the old and new is not good at all.  It's already done critical replication, now just progressing with initial full replication, but it's taking a LONG time (days). 
    Is there any way for me to switch the new DC to finish it's initial replication with another DC, that's on a much better network link?  (Or am I stuck as is with the extremely slow link?)  I would prefer to not kill this and do metadata cleanup if
    possible, prefer to sync w/another DC.  Thank you.

    Hello,
    If the connectivity is unstable, you will have problems in AD replication.
    You can use IFM to avoid replicating much information: http://blogs.technet.com/b/activedirectoryua/archive/2009/01/19/installing-from-media-ifm.aspx

  • Help needed for replication environment. atleast get me good URL links.

    Hi friends,
    Our database is having nearly 150 tables and 200 views, 10 database procedures, 5 database triggers, 5 DBMS_JOB, and 15 users are using. it is ORACLE 8i under win 2000 environemnt. daily 5000 new records are inserted into the database.
    now i want to have a standby database, read and write complete replication of master database, in this following scenario.
    all the clients are conneting uisng connect string "terminal", if any thing happens to the "terminal" computer, the users could be able able to connect using "terminal1" lets say this "terminal1" is the stand by database and it should be functional as original.
    any body can give documentation, easy methods, or step by step documentation. we have access to metalink also. but failed to get easy methods to achieve this.
    thanks in advance

    is a very complicated thing you want to do: it is what Oracle call the Standby database or Dataguard - it's part of the Enterprise Edition, but I don't know whether Oracle charge extra for it. If you are not an experienced Oracle DBA (and, forgive me, but some of your other posts suggest you are not) you do not want to try doing this yourself. Pay Oracle's wergild and get their solution for this.
    Replication is really not suitable for this sort of process as it doesn't function well in real-time; this means you cannot guarantee keeping the two databases usably up-to-date. That causes a problem later on when you need to switch to your back-up database. And again when your original database is back online. Plus replication is flaky and has performance costs (voice of experience).

  • The Microsoft Exchange Mailbox Replication service was unable to process a request due to an unexpected error. Event 1121

    Hello all,
    We migrated our Exchange server from 2003 to 2010. After the mailbox move requests were finished we had one that was stuck. We basically skipped it as we had a lot of other things to finish over the weekend. Here we are a year later, the old exchange server
    is gone and so is an old DC. I am receiving an error every four minutes in event viewer.
    The Microsoft Exchange Mailbox Replication service was unable to process a request due to an unexpected error.
    Request GUID: '3e46b7cb-2ac0-42c1-98e8-57517a19ee40'

    Error: Unable to find 'OLD Domain Controller' computer information in domain controller 'OLD Domain Controller' to perform the suitability check. Verify the fully qualified domain name..
    I have checked in EMC for move requests. None are listed. I have checked the DCs listed in EMC properties. Old DC is not listed.
    I also ran these commands in shell to attempt to cancel the stuck request.
    Get-MoveRequest -MoveStatus Completed;Pending;InProgress;Failed;CompletedWithWarning;Suspended;Queued;CompletionWithProgress : Remove-MoveRequest
    NO changes. Still throwing error. Any suggestions? I also tried using the guid and shell to look at the move request. Systems replies no such request.

    Hello,
    Please try to restart iis services to check the result.
    If the issue persists, I recommend you ping you DC server on your exchange server to check if your exchange server can communicate with your DC server.
    If there are other DCs, please try to use set-adserversettings cmdlet to specify a DC for your exchange server.
    Set-AdServerSettings

    Besides, please install the lasted rollup to check the result.

  • Exchange 2010 "This message could not be sent. Try sending the message again later, or contact your network administrator. Error is [0x80004005-00000000-00000000].

    Exchange 2010 "This message could not be sent. Try sending the message again later, or contact your network administrator.  Error is [0x80004005-00000000-00000000].
    In a mixed client environment, mostly Outlook 2010 & 2013 clients. Only Outlook 2013 clients (about only 4 mailboxes) are receiving this error immediately after sending an email. My temp band-aid at the
    moment is to: from the client, go into the "address book" & select a different address book like "Contacts" & then select the address again & select the Global Address List, which is the default. (it will have the users email
    + at the beginning of the field, it reads, Global Address List - (email of the user), then I close Outlook & open it back up, & the problem is solved. But on some mailboxes, not all, the issue comes back. From my research, I know that our individual
    mailboxes do not send out over 500 emails in one day. Most users will send out maybe 20 or 30 in one day, so I don't think it's that. 
    But I'm not sure if this is related, but I have noticed that the log files for the Exchange 2010 seems to only hold logs with date stamps of only a couple of days. It used to hold log files indefinitely until they were archived, deleted, etc. So, this is
    a new, unusual issue I have seen as well. 
    We have 2 .edb's, one active: 78 GB's and one disabled at 7 GB's. Exchange 2010 is running on Windows Server 2008 r2, Enterprise Ed. We have had Exchange 2010 running now for about almost 2 years now and this is the first time this particular issue has come
    up.
    Thanks.

    Hi,
    You can refer to the following steps to rebuild an Offline Address Book.
    1. Open EMS. Update OAB using the Update-OfflineAddressbook "offline address book" cmdlet. Restart Background Intelligent Transfer Service on the Mailbox server.
    2. Initiate OAB replication from mail box server to CAS server. Execute for each CAS server using the Update-FileDistributionService "CASServerName" cmdlet.
    3. Start Outlook and download OAB.

  • Excel file save error: Someone else is working in file right now. Please try again later.

    When trying to save a modified Excel file, which has been opened from a network share, our users are receiving the following message:
    Someone else is working in "\\domain.com\users\username\Document.xls" right now. Please try again later.
    The clients that have been affected are Windows 7 clients, and the DFS share is being served from a Windows 2012 server. I have already confirmed that DFS replication has not been enabled, so it isn't trying to lock files for replication. I have also disabled
    any real-time scanning that is occurring on the client to make sure that the AV software wasn't locking the files. I did notice when viewing the list of Open Files from the server's Computer Management console that when a users experiences this issue the file
    appears to be opened 4 times. Three times it shows that it was opened in Read mode and the 4th instance shows an Open Mode of Write. Typically, a file which is working correctly should just show one instance with the Open Mode of Read+Write. None of these
    open instances are temporary files preceded with a ~.
    Any thoughts?

    Hi,
    Does the issue occur in other operation system? Which Office version are you using? Have you ever tried to test with word document, PPT file or txt file?
    Based on your description, the issue may be caused by the same file open multiple time in computer management on SQL server. The user probably has User Access Control (UAC) enabled on the machine and it is not letting him overwrite the existing
    copy of the file because she does not have it open in administrator mode. UAC will block overwriting (saving) the existing file without Administrative privileges and it will automatically open the save as dialog so you can save with a different name and
    if you click save without changing the name at the point, it tries to save as a new file over the existing file and it can't because the file is open.
    I recommend you check the user's permission (Which showed in Computer Management console) and end the Excel file instance in the task manager of the user's client.
    Also, we may try the workaround: Save it to local drive(like drive c:) and then copy it to DFS.
    Thanks

  • Sql server replication from SQL SERVER VERSION(7.0) to SQL SERVER 2005

    Hi All,
    We are trying to create a replication between Sql server 7.0 data to SQL server 2005 data . We tried to create a local subscription in Sql server ,when tried to connect to publisher  running in Sql server 7.0 it is showing an error message
    like "This Sql server vresion(7.0) is not supported" .
    Could any one please help us with this issue ?
    Thanks
    Sandy

    Hi CRM_Learner,
    SQL Server version 7.0 Service Pack 4 (SP4) is the earliest version that can participate in a replication topology with SQL Server 2005. We need to verify the version of SQL Server. If you configure transactional replication with updating subscribers,
    for a SQL Server 7.0 Publisher, only SQL Server 7.0 Subscribers are supported. SQL Server 7.0, 2000 was out of support in the SQL Server Forums. I suggest you install SQL Server 2005 or later version to configure the SQL Server replication.
    For more information, there is a detail about using multiple Versions of SQL Server in a replication topology.

    (If there are additional customer-specific Z modules that are
    registered in this table, you may have to change the item numbers. The
    standard modules that are used to create business partners or

    modules, which need these objects to exist before they can be
    processed, must therefore have a line item number greater than
    1000000. This applies especially to modules that have line item
    numbers greater than 100000 but less than 1000000)

  • BP replication from CRM 7.0 to ERP 6.0

    Hello.
    I was made customizing replication BUPA_MAIN object from CRM 7.0 to ERP as of Best Practics.
    When i creating a BP in CRM it's replicating in ERP as Customer only, not as BP.
    What I need to customize that BP is created during replicating from CRM?
    Thanks

    Hi All,
    I am also replicating customer master data from CRM-ECC. I am creating BP as Sold-to-party (STP) role and mapping that to a Z-Acc Group (copy of std. STP in ECC).
    One thing I want to clarify from you all is that in our case,
    In ECC, Recon Acc Field in Co. Code data is mandatory, but in CRM there is no concept of Co. Code.
    How do we handle such a scenario, because in this case there will be error of mandatory fields not matching on both sides.
    Please share your experiences or solutions for such a scenario.
    In addition to this, for tackling this issue,
    We created an enhancement on ECC side, to take care of this but while replicating BP's from CRM to ECC, there was en error "No batch input for screen SAPMF02D 100".
    When we raised this issue to SAP, their reply was as follows:
    1. There are various problems, but the main is probably that we reach the CALL TRANSACTION statement
    with FT[] empty. I have skipped the "ENHANCEMENT 24 ZCRM3" which has been added at the
    end of function module DEBITOR_BDCDATA and then FT[] was populated.
    Then i faced several missing data regarding the mandatory fields;
    first one was missing country in the address.
    ==============
    2. The root cause is in the "ENHANCEMENT 24 ZCRM3" which is at the end of FM DEBITOR_BDCDATA.
    This enhancement is a custom development from your side.
    It first clears IBDCDATA[] and fails to rebuild it because the conditionIF FT-FVAL = '0001'. is NOT fulfilled. (here FT-FVAL = 'Z001') Consequently, the internal table FT[] is later cleared which makes that the call transaction XD01 is executed with no data at all.
    ===============
    If we skip the enhancement, there will always be an error for mandatory fields.
    Please share your experiences on such an issue.
    Thanks and Regards

  • Merge Replication from 2012 SQL Server publisher/distributor to 2014 SQL Express subscriber

    Hi, I'm having a question about which version to use when running SQL Merge Replication.
    In my test enviroment I have a SQL 2012 server running as Publisher and Distributor for my Merge Replication. I have now set up a test client running Win7 with SQL 2014 Express as a subscriber. The subscription initializes and runs perfectly.
    But according to the SQL documentation this should not be possible as it states that the subscriber should have a version number equal or lower than the publisher. My subscription client was set ut using SQL-scripting, if I try using the wizard it will just
    cause an error message telling that this is not possible since the client has a newer version number. I still not encountered any problems after I set it up using the script with the sp_addmergepullsubscription and sp_addmergepullsubscription_agent procedures.
    The roll-out of my solution will start in a few weeks and I now have to decide whether to use 2014 Express or 2012 Express on the clients. Using 2014 Express will save me for a lot of upgades in a year or two. The 2012 SQL Server running as publisher/distributor
    will be upgraded to/replaced with a 2014 Server in some few months.
    I'm looking for good advices and recommendations for what to choose on the clients, 2012 Express or 2014 Express. Are the any known problems with using 2014 Express as a subscriber to a publisher/distributor running 2012 SQL Server?
    All responses are welcome!
    Regards, Anders

    Hi,
    As you understand that a Subscriber to a merge publication can be any version less than or equal to the Publisher version. When you set up a subscription from a publisher to a subscriber using SQL Server Management Studio, you will get error
    “The selected Subscriber does not satisfy the minimum version compatibility level of the selected publication.” And you can use T-SQL script to get around this error message.
    I would install SQL Server 2012 Express on the clients. Here is the reasons:
    1. If you upgrade the publisher to SQL Server 2014, it is still working with SQL Server 2012 on the subscriber.
    2. I cannot tell whether there are other potential problems if I choose the later one besides the error message.

  • VSS timeouts on Hyper-V guest, Exchange Replication Service, CU5

    I'm having a problem with a Hyper-V guest that is running Exchange 2013 CU5.  I will say I have had issues with this VM since installing CU5.
    Note:  I am doing a backup from within the VM guest, not from the host.
    The scheduled backup takes a long time to complete, an entire weekend to backup 150GB to an ISCSI disk.  In addition the CPU time is very high (58%) while this is happening.  Attempting to open the backup manager window consistently makes the CPU
    time hit 99%.  When this happens Outlook clients will fail.  When backup manager opens it will continually say "Reading data; please wait..."  If the backup manager happened to already been open, the backup job will say "Volume
    1 0% of 4 volumes."
    The processes taking up the CPU time are Microsoft Volume Shadow Copy Service  (24%), Microsoft Block level backup service (62%) and virtual disk service (12%).  Memory use always hovers around 65%.  If I attempt to kill the processes with
    task manager, there is no change.  If I use the kill executable it will say the process is not running.  I cannot stop the corresponding service either.  I cannot stop the backup.  I cannot query vss writer status.  I cannot restart
    the ISCSI service (device in use.)  Restarting the NAS that contains the ISCSI target does nothing.  The only recourse is to restart the server.
    If I restart the server and start a backup fairly soon after, the backup completes normally, in about an hour.  During a normal backup CPU usage is at about 30%.  The Microsoft Volume Shadow Copy Service runs at 0% CPU time as well as the virtual
    disk service.  The Microsoft Block Level Backup Engine runs at 10% CPU time.  The scheduled backup is set to start at 9:30pm.  I have also tried changing backup times.  If I restart the server at 4 am and do not run a manual backup, the
    scheduled backup performs poorly.
    After some digging I find these errors:

    2 After a restart of the server, the server may have no, or limited connection to the network.  It may or may not have an exclamation point on the network icon.  If there is no exclamation point, it can ping other network resources, but inbound requests
    and pings, will fail.  The event log shows that the network should be available while booting, but it's not since it cannot communicate with active directory.  The fix for this is to disable/enable the network adapter and then all is well.
    I really need some help figuring this out.  Again, never had an issue with this server prior to Exchange 2013 CU5 being installed.

    Hi,
    The reason I think it is Exchange related, is that from the error message it mentioned:
    A VSS writer has rejected an event with error 0x00000000
    And then it indicated it is "Microsoft Exchange Replication service VSS Writer". 
    The Microsoft Exchange Replication service VSS Writer (Instance 7a465f3f-25ba-45b2-952a-870a6ddc2f2b) failed with error 80070020 when preparing for a backup
    Later I found this article:
    How to turn on the Exchange writer for the Volume Shadow Copy service in Windows Small Business Server 2003
    http://support2.microsoft.com/kb/838183/en-us
    It mentioned that with turned on Exchange writer, we will fail to do system state backup and Exchange backup at a same time:
    The Exchange writer may cause conflicts with the information store backup feature of the Backup utility. The information store backup feature uses online streaming to back up the Exchange databases. If the Exchange writer is registered, the Backup utility
    may log errors if you try to back up the system state and the Exchange information store at the same time. (For example, the Backup utility may log Event ID 8019.)
    In order to confirm if it is the cause, please test to:
    1. Create a backup-once task to backup only a simple file - this is a quick test to confirm if Windows Server Backup is fine or not.
    2. A second backup-once task to do a system state backup without any exchange related information.
    3. If both failed, please test to disable Exchange Writer and redo test 1&2.
    It will take us some time on doing these tests. The reason is to figure out if it is Exchange related or not. I'll continue discuss with you if any new clue is found.

  • Problem with File Based replication in Weblogic Express 10

    Hi,
              We have Web application (exploded war) file deployed on Weblogic Express 10, to a Cluster of three Managed Servers (all three on different physical machines).
              We are using File based session persistance in weblogic.xml
              We have a shared location for all the three servers where we will be sharing the Session data.
              When we start the application, its works fine and is very fast, but after sometime the application slows down.
              Troubleshooting the Issue we found that its a problem with file based replication. By using File based replication every user session is stored in form of directory inside shared directory. So after sometime thousands of directories are created inside the shared directory where the session information is stored. So when we access the application, its waiting for lot of time with Message Session Monitor .... (this is because its browsing through the shared session storage directory for lot of time for session information as it has lot of directories) and finally after a long time like 10 mins we get the Application Home Page.
              When we clean up all the saved sessions inside shared directory, the application works fine, But we will see the same sometime later may be after 3 or 4 hours when the shared session directory has lot of session information stored in it.
              Is there a way to clean up the saved session information on file system as soon as that user session is closed by using file based replication.
              We cannot used Inmemory replication as our Appl doesnt support it.
              Please advice as it is a major show stopper in our Production Mirror env.
              Weblogic Consultant

    It is possible to reduce number of live session by configuring very low timeout-secs weblogic.xml. Default is 60 minutes.
              More details are here..

  • Error in creating replication ora-04052

    Hi, I am having trouble creating my replication objects in oracle's replication manager. I am using two 8.0.5 db's, and the repman states that it cannot find the view [email protected] I did not see the view when I ran a manual select under sqlplus. The error message says to fix the error, to run a script to create the views. I have seen kglr.sql for 7.3, but I cannot find the proper script for 8.0.5 . Could anyone help me with the proper script name to run get replication working?
    Thanks,

  • 451 4.7.0 temporary server error. please try again later. prx4

    Hello,
    in my environment i can send/receive mail.
    When doing some checks i will end up with this error :
    451 4.7.0 temporary server error. please try again later. prx4
    I have tried the following without results :
    Exchange 2013 SMTP error "451 4.7.0 Temporary server error. Please try again later. PRX3"
    This error message seems to be caused by DNS issues in the Exchange 2013 set up. Exchange then rejects all emails like this. It is not quite clear what Microsoft means with this error code and the various PRX-numbers at the end - we've also seen PRX1, PRX3,
    PRX7. There is no list and no documentation on them available.
    From customer feedback we found these ways to solve the problem:
    Disable all unused network cards.
    Check all DNS server entries in the configuration of your network cards (check
    all network adapters) and make sure not to reference server 127.0.0.1 as DNS server but to use the real IP address instead.
    If you have more than one fixed IP address in the server add an entry for each IP address in the hosts file (C:\Windows\System32\drivers\etc\hosts) formatted like "192.168.1.1 SERVERNAME".
    Important: Do load the latest Exchange 2013 updates, especially CU1 if you haven't done that already.
    Please delete the receive connectors in Exchange and create one new receive connector. Use the "front end" instead of "hub transport" setting and vice versa.
    What do do, to fix this issue?
    Thx

    Hello,
    Please use dcdiag command to check if all DC run normally.
    Please use repadmin /showrepl command to verify DC replication status.
    Please check if there is any related error in application log.
