ECC6 System Recovery

Posted on Jan 04, 2008 at 12:06 PM 18 Views

Dear All;

l have a question on the complete recovery for ECC6/Oracle system central Instance system.

l have a full backup (offline and online), if the current system (with ECC6/Oracle10g/Windows2003) crashed and l need to setup in another new server, how should l do?

In 4.x version, l can install the Central Instance (CI) only, then restore the source database in target server then l can connect the CI to the database.

But for ECC, in the sapinst program, for the Central Instance System installation, there is no seperate installation or CI and Database instance. So, even l have the database backup, how to l setup the SAP binaries, user ids, user environment etc? (Basically, it is like to install the CI)

The notes 659509 mentioned about the steps on how to recover the SAP4.7/Oracle system, what about ECC6? can anyone advise what is the proper procedure for the ECC6/Oracle/Windows or Unix?

Thanks

Jordan

    Hi,

    download the system copy guide from

    service.sap.com/instguides

    prepare database instance -->

    install DB software,

    recover DB

    run sapinst ( following is for win/oracle)

    SAP ERP 2005 Support Release 2 -> Additional Software Life-Cycle Tasks -> System Copy ->Oracle -> Target System -> Central System -> Based on AS ABAP -> Central System Installation

    regards,

      Hi Jordan,

      another tip, the whole installation takes a long time, but it is necessary to install ECC6. Instead, you can install NW AS ABAP only (I have forget the size, only about 30G), with which you have also CI.

      Remeber, DB instance is not important at all. So, you can also ignore all the import errors during the installation.

    Hello,

    although the installation concept of ECC6 is a little different from previous version. But the recovery procedure could be done in the same way. That is,

    1. install the CI instance until it is finished(both CI, DB will then be installed). It means this will take longer than before.

    2. destroy the the database (it contains only data from SAP)

    3. then recovery database as before.

    Of course, this is only theory and you need practice it. Have fun!
