Disaster Recovery setup for SAP Portal

Hello,
I am trying to setup a DR site for our portal system. We are using EMC Recover Point to do the SAN replication between Production and DR site. We are using MSCS cluster with one CI and DI in Production. For DR, we are planning to go with a distributed installation with one portal and database node.
Can I create the DR system using System copy assuming that the SID is going to be the same, and the host names/IP addresses are different. How can we make sure that the custom applications deployment in production is in sync with the DR site? I don't think replicating the database preserves everything as the Java system persists data in both the database and the file system, for example the Software Delivery Manager (SDM) is persisted in the file system.
So, how can I make sure that the file system is also gets replicated between production and DR site? Should I keep the DR system shutdown and bring it up for weekly sync up or it can run parallel with the production system?
Thanks.

Hi,
Regarding the system copy, last time I did one myself (its a while ago so I'm not sure if it is still a limitation) it was not possible to have the Target SID the same as the Destination SID.
If this is not a limitiation anymore then yes you can use the system copy procedure as it also takes the SDM with it.
Cheers,
Benjamin

  • Planning Disaster Recovery Site for SAP ERP ECC 6.0

    Dear All,
    I am planning for DR ( Disaster Recovery ) Site. Our current environment is
    Production Site
    OS        : AIX 5.3
    DB        : IBM DB2      version 8.2
    SAP      : SAP ERP 6.0 ECC 6
    Disaster Recovery Site
    OS        : AIX 6.1
    DB        : IBM DB2      version 9.5
    SAP      : SAP ERP 6.0 ECC 6
    I have following confusion in planning the solution.
    1 - If I export the data at db level from production site and import that data in DR Site ...  than DR Site will be equivalent to Production Site or not.
    2 - if answer of point 1 is yes then for SAP DR ...  HADR is the best solution or there is any other better solution exist.
    regards
    Syed Saifuddin

    Hello Syed,
    If you export from the prod db and import into the disastor recover db then they will be the same provided that SAP environment is all the same. I would recommend that you update the prod side to the same db2 release and fixpack level as soon as possible though as 9.5 (or even better 9.7) has some advanced features that make administration alot easier and save much space.
    HADR would be the best setup for disaster recovery in db6 environment.
    Check the following documentation which should answer most of your queries.

  • Disaster Recovery Plan for SAP BW

    Dear All,
    We are planning for robust Disaster Recovery Site for BW . We have similar  R3 & BIW  servers at DR site at different location and data is being copied every 3 Hrs.
    R3 & BIW at DR site is exact replica of primary site. When primary site is down DR site will act as a primary. In that case we might face data loading issue from DR R3 to DR BW because of source system change. If we change the source system then we loose data consistency and might need initialisation. We are looking for the solution which will involve less efforts to up the system.
    Does anyone has done this or overcome this situation ?
    Regards,
    Manish

    Hi Raman,
    We are doing disaster recovery test for both ECC and BW systems so whole PR system switched to DR system for some time and then back to PR system. so in that case what precautions we need to take from BW side?
    Thanks

  • Best Way to setup a disaster Recovery site for a logical standby database

    I have a logical standby DB (L1DB) as a reporting db on the same machine as the primary (P1DB). We are planning on building a disaster recovery site with similar hardware and potentially have disk mirroring of atleast the redo log files.
    The DR site can hold an additional physical standby (S1DB) for the primary (P1DB). I am trying to understand what would be the best way to setup the Disaster Recovery site for the L1DB logical stdby. Ideally, when the disaster happens, and I no longer have P1DB and L1DB, I should be able to switch to S1DB as the new primary. But how do I setup to have a L2DB that takes the place of L1DB and has its contents and can be setup as a logical standby of S1DB?

    If you already setup one logical standby, then you know how it works, so not sure what question you are asking ?
    Personally I would setup L2DB as a standby of the original primary P1DB. Having downstream standby databases complicates things, and adds additional lag between primary transaction time and L2DB apply.

    Hi,
    The disaster recovery strategy should include a backup and restore plan that determines which data should be backed up and the procedures that will be used to recover it.

  • Business packages for SAP Portal 7.3

    Hi,
    as far as I know at the moment there are no business packages existing for SAP Portal 7.3. Is this correct? If yes, how are the different business packages scheduled?
    Bye,
    Timo

    Hi Timo,
    with EHP5 you may choose between WD JAVA and WD ABAP.
    Just check
    http://help.sap.com/erp2005_ehp_06/helpdata/en/48/a2d0be5444690ae1000000
    0a42189c/frameset.htm
    As soon as you have decided to use one of the versions you may use the Maintenance optimizer to determine the pacakge.
    The release of the portal is not so important for the business packages. The NW release is just important if you run the JAVA applications on this machine as well. For NW 7.3 this means
    you will need the 633 and 630 packages.

  • Use only Internet Explorer for SAP portal

    Hello,
    We have a requirement to use only internet explorer for SAP portal.
    When we try to use portal in any other browser, it should display a message saying "This browser is not supported for the application" (or any other message). But purpose is, the portal application should be usable in only one browser i.e Internet Explorer.
    If any one have any idea on this, how this can be implemented, then please share the same. I tried to find if there are any standard SAP portal parameters, but haven't come across any.

  • CSM SLB for SAP portal 5.0

    Dear All!
    Is there somebody who have experineces with SLB for SAP portal? The main question is : Which sticknies to use: SSL or IP based? How to configure IP based, because I did not find good explanation of "netmask" parameter in sticky,sticky-group command. What happen to sticky connection, when real server fail. Is it rebalanced?
    Thanx!
    Gabriel

    Hi Gabriel,
    I do not have experiences with SAP-Portal Loadbalancing but from my experience with loadbalancing I would say that this decision should be done regarding the surrounding environment. If there are proxies around which are used to connected to the loadbalanced VIP I would suggest SSL-Session balancing/stickieness. If clients are directly connecting towards the VIP a client-IP-stickieness might be easiser to troubleshoot.
    Regarding the netmask issue:
    Unfortunately there is no real documentation (I did not find any so far). I can only tell you the result out of my experience:
    A netmask 255.255.255.255 is kind of host stickiness and 255.255.255.0 a stickieness of a /24 network. In other words I think that all Clients with a network of 10.1.1.0/24 are sticked to the decission once taken for one of the hosts in this segment while the sticky timeout did not take place. Maybe one can confirm or correct this.
    Regarding the thing with the failure of a real server:
    With the corresponding failaction defined in the serverfarm you decide what to do in case of an error of a real server. The stickiness should be corrected correspondig to the results you define with the failaction command.
    This is how I dealt with those sticky issue when doing firewall loadbalancing with client-IP-Stickiness.
    Hope that helped.
    Kind Regards,
    Joerg

  • Need help for Disaster Recovery setup and configuration

    Hi Gurus.
    We are planning to have disaster recovery test plan. Normally we setup our network at another site and then restore data there and then do configuration and setup to run SAP system to new network.
    But this is little more time consuming. We are planning to do something which will might save our time.
    We want to create one Application instance on Central instance on current production server. This instance will be "deactivated" and will not run on production server.
    When we will do the disaster recovery, we will restore CI filesystem to Disaster recovery network. That time this new application instance  will aslo get copied. Once this is done, we just need to go to this instance and start SAP System. This way we will save our time of configuring the new instance and then starting it.
    e.g
    Production host -> prdhost1
    Central Instance -> /usr/sap/P01/DVEBMGS00
    and it's subdirectory: data, work, log, sec
    create new application instance -> /usr/sap/P01/D03
    and it's subdirectory: data, work, log, sec
    create new instance profile -> P01_D03_prdhost1, START_D03_prdhost1
    this configuration will be created but SAP instance will not be started. It will be copied to Disaster Recovery new site and in that new network , there we can start this new application instance.
    Please let me know if we can do that ? if yes, are we going to face any issue in production?
    Other than mentioned above, what FileSystem we need to take care for creating new instance?
    Any help will be highly appreciated.
    Thanks in advance
    Best Regards,
    Basis CK

    Hi!
    Sorry but your scenario is a little bit confusing.
    Let me guess if I understood, you want to configure a "virtual" instance to be able to use it in case of DR.
    I don't advise you to do things that way. Why not use virtual hosts and virtual instances like we do when implementing instances within a cluster or metrocluster.
    You must have the license from DR server installed. I you use virtual hosts all DR issues like printers, logon groups, RFC groups, etc... will be solved.
    If you use virtual hosts and virtual instances all you need to do is replicate the environment into DR site, restore the system and start production.
    Of course... you are using UNIX and within UNIX world all these things are much easier.
    Bear in mind that if you have JAVA instances then I think this is the only recommended procedure.
    Cheers,

  • How can generated EWA for SAP Portal system

    Hi Guru there,
    Usually generate EWA should maintenan RFC, We have SAP Portal systems ( prod PP1 and test PT1 and dev PD1), but they are not appeared at saplogon and no general SAP interface, only operationing system level we can start/stop SAP system and database and from the operating system browser can see the portal work normal ( 50000 port) or not.
    How can I generate EWA from solman?

  • Disaster Recovery scenario for MSCS Production system.

    Hi
    Our production system is on win2008/sql2008 MSCS. We decided to install a disaster recovery system. We will use a database replication software. If we have a standalone production system, not a MSCS system, i know that i can install Disaster Recory system with same SID and hostname and i don't need any homogeneous system copy procedure to switch to DR system. But in our scenario, we have many hostname (sap cluster group, sql cluster group, hostnames of nodes... etc.).
    How can i install my DR system (which hostname.. etc.) to make our DR scenario easy?
    Best Regards...

    You May have trouble with RFC connections:
    So, one possible solution is, your new server name(Host name) should be your message server name to minimise the trouble and you have to maintain this for all RFC connections (to Prod ECC system) to virtual host which could be message server.
    If I could think if any other possible issues, I will update.

  • Cisco Expressway Core & Edge Cluster, or Disaster Recovery Setup

    Hi All,
    Dear experts,
    I have two sites HQ & Branch.below are my questions for Expressway Core & Edge Cluster
    1. Can i create one cluster for 6 sever for  Expressway Core and distribute 3 server in HQ &  3 server in Branch for HA
    2. Can i create one cluster for 6 sever for  Expressway Edge and distribute 3 server in HQ & 3 server in Branch for HA
    3. How would be the DNS SRV records and call flow work if the main site  Expressway Edge goes down in HQ. How the Branch Side Expressway Edge becomes active for B2B calls.
    4. What is the best design to have disaster recovery for Expressway core and Expressway Edge between Sites(HQ & Branch)
    Regards,
    Irf

    Regarding 1 and 2, as long as the round trip delay is no more than 30ms maximum, you should be fine.  I presume the HQ Branch offices for the Expressway-Core have a shared internal network, since the Core goes inside the corporate network, while the Edge goes in the DMZ or outside the network for public access.
    For 3, as long as you have your SRV records setup correct, you can set the priority of which office gets used first, and then second, in case of a failure.
    I don't have an answer for 4 unfortunately.
