Log frequence for productive system

Hello!
We use SAP DB (version 7.7)  and use auto log function.
We configured the redo log frequence so, that every 10 minutes a new redolog will be written to hardware drive.
Question:
How does this setting (log frequence of 10 minutes) affect the performance of the SAP system?
And which setting (every 10, 20, 30 minutes) should be set for productive system?
kind regards

> My question is about the log settings. Untill today the redo logs were written to the drive, when the max. size of redo log (appr. 1 GB) has been reached.
> Now I changed this settng, so I have every 10 minutes a new redolog file on the hardware drive.
So again my question: Why did you change that? What was the reason to do so?
> The questions:
> Does this frequence (10 minutes) affect the performance of the server (network, SAP system, DB)?
The default max time between database savepoints is 600 seconds - so 10 minutes.
> What is the recommended setting to redolog setting for productive systems?
There is no recommended setting for that, it all depends on what you are trying do. If you want e. g. a shadow database running "after" the production database for 10 minutes, then you use that 10 minutes setup. If you want an hour you configure an hour etc.
It's all based on your setup and what you want to do.

  • Support message and change requests only for production system

    Hi guys,
    I would like to connect the solman helpesk with CHARM ( CHARM is still running ).
    In CHARM I have to create a CR only for production system. ( don't know why - but works as designed).
    In SAP helpdesk I can create support messages for every kind of system type but if I want to connect both (HD and CR) , the source system (ibase component) of the issue will copied to the CR and runs in error because of the rule (only p-system) of CHARM.
    Of course I can change the ibase to production system manually in SDCR but it seems a very error-prone method.
    Now my question: is it possible to change the ibase component due to the creation of CR by copy rule or something like this?
    Kind regards
    Rayko

    Hi Rayko,
    We do not have this option.
    Once in ChaRM, we assume that the changes will always correct an issue in the PROD system.
    I would recommend to open the tickets directly with the PROD system IBase, once the issue is also happening there.

  • Restrict print out of Purchase order only for Production system

    Hi,
    I want to restrict print out of Purchase order only for Production system, don't want to take it in devep or quality.
    is there any identifier to find the system is production or development.
    can anyone tell me how to restrict it,
    is there any function module, not based on client system.
    Thanx in advance
    Kesav

    Hi Kesavarathinam Vaidyalingam ,
    yes, I also use thomas' suggestion using
    t000-cccategory = 'P'.
    to determine productive client.
    Just one small hint: I found this condition as true in a test system: The admin had done a system copy to create a fresh test client - but forgot (or did not see a good reason) to change t000-cccategory = 'P. to  t000-cccategory = 'T'.

  • Content Server config for production system - oac0

    Hi all
    We are setting up content server for our ERP 2005 system, and I am wondering what best practice is for our scenario.
    We have one content server (CST) for development and test systems on host A, and one content server (CSP) for production system on host B. The Archive link configuration in dev and test points to CST. When this is transported to production, it will point to the wrong content server and I will have to reconfigure the archivelink in production to point to the correct content server (CSP).
    What is the best way to set up the production system to point to the content server CSP on host B? Should I define a new content repository in t-code oac0 in dev, and transport this to production? Should I define the new repository directly in production system??
    Please advise.
    Best Regards,
    Thomas

    Hello,
    I had the same problem a few years ago with R/3 4.7.
    I don't think there is a perfect solution but here is what I did :
    In the DEV system, in OAC0, I created 2 content repositories, one for the test sytem and one for the production. I transported these 2 content repositories in the production system.
    In the DEV system, in OAC3, I created temporary links from my business objects to my production content repository. I released the request order.
    Then I deleted these links which are wrong in the DEV system. I transported the order in the R/3 production system where these links are right.
    In the DEV system, in OAC3, I then created  the links from my business objects to  my TEST content repository. I released the second request order.
    So my config is now OK in my test and my production system.
    When we refresh the DEV system by a database copy from the production system. We just have to reimport the test request order to switch the links to be OK on the DEV system. We don't have to recreate the test content repository as it was defined als oi nthe production system.
    I am not sure that this is clear but this works for us with no problems since 2002.
    I hope this helps.

  • Project Management Question - timelines for Production system deployment

    Hi
    I need an expert advice on setting up timelines for establishing an Oracle Apps Production environment. We are implementing Oracle HR & Payroll at an organization.
    Our system architecture is a 2-node application tier and 2-node DB tier (RAC). RAC is configured by another party and we only have to prepare the application tier (2 nodes)
    We would be installing Oracle Apps R11i (11.5.10) with jserv load balancing on the 2-nodes
    Can anyone suggest how much time this should take to install/configure & patching of the application tier (on 2 nodes)?

    Create the function modules in SE37 and set the remote-enabled flag in the attributes section. Then import them into XI.
    Create a custom Z table through SE11 on each system to store any data, and the code in each function module would reference it. (Either that or just hard-code everything)
    In short yes it can be done through SE37, no you don't need SE38.
    I think you're talking about function groups which is a container for the function module. You can do everything through SE37 if you use the Goto->Function Groups-> Create Group option and give it the same name as your Function Module.

  • Backup and Recovery procedures for production system

    I am trying to decide and test a best backup/recovery approach for our DBXML database in the production environment. Right now I am trying to go through the documentation.
    http://www.oracle.com/technology/documentation/berkeley-db/db/gsg_txn/CXX/filemanagement.html
    What is the best option among offline, hot and incremental backups?
    I am thinking of implementing incremental backups.
    What are the constraints in implementing incremental backups? Is there a detailed step by step example to do this?
    Can I test the backup and recovery procedures by copying the db files and log files from Linux (production) environment to my local machine (Windows XP)? I see only one log.00000000xx file in production and staging environments. It is of same size 52428800 in all our environments (both production and staging) at this point of time.
    What is __db.001 file? What is the significance of this file in backup and recovery procedures?
    A detailed input with example is greatly appreciated.
    Thanks in advancs

    Raghu,
    A couple of points, up front:
    1. the __db* files are the environment (cache, locks, various shared memory regions), and are not part of backup, other than the fact that you need to checkpoint or otherwise flush your cache to your database(s) for a full backup.
    2. log files are not architecture-neutral. That is you can't use a log file created on linux and just use it safely on another hardware platform. It's OK to copy them around, but they can only be used on the same architecture that created them. Database files (containers) are entirely portable among hardware and operating system platforms.
    I don't know of a step-by-step cookbook for backups. This is because of the variations among application needs. However, the procedures described on this page are pretty straightforward:
    http://www.oracle.com/technology/documentation/berkeley-db/db/gsg_txn/CXX/backuprestore.html
    I'm not sure what you mean by "constraints" on incremental backups. The only constraint is that you need to have a full backup first, or you won't be able to recover properly. Based on what I said above, the other constraint is that you'll only be able to recover on a machine of the same architecture as the one that created the log files.
    As for testing, you can certainly copy your database and log files to your Windows machine, treating Windows as an offline backup. If you want to test recovery, you need to copy the files back to Linux. You'll start seeing additional log files when your log data starts to exceed the configured log file size.
    Let me know if you need more clarification,
    Regards,
    George

  • Using the Log Viewer for two systems on same host

    We have two Portal systems installed on the same host server.  The log viewer only identifies and displays the log files from one of the systems (A).  This is the case even though I started the log viewer while logged on as the <sid>adm for system (B).
    In the configuration of the Log Viewer, I do not see an option to have it add another "system" to the local host.
    How can I configure the log viewer to display logs from both systems installed on the same host?
    Thanks,
    Bob

    Bob,
    with the port you can distinguis between the servers. both portals should have unique ports on the same server.
    for you relevant is the P4-port.
    these settings work for remote servers:
    Name: <SID>
    Host name: <hostname of server>
    Port: <P4 Port, normally 5<SysNr>04>, you can check this at: http://<host>:<port>/sap/monitoring/SystemInfo under the Dispatcher infos
    Connection: J2EE
    User: <admin user>
    Password: <admin user password>

  • Sensitive Transactions List for Production System

    We are looking for a comprehensive list of sensitive transactions (e.g. SE38, SE37, LSMW, etc) that should NOT be assign in Production environment. Transactions that will trigger audit violation in PRD environment. Hopefully with documentations or whitepapers to backup this list.
    Thanks,
    Lye

    They could only access data from SE16 if they have the corresponding s_tabu_dis activity for the authorization group to which that table has been assigned.
    If the auth group is not maintained, SE16 will assign the value '&NC&' to it and check it.
    If granting s_tabu_dis for other tables sharing the same auth group is inappropriate, then these can be re-assigned in transaction SUCU.
    I still don't see where SE16 or SM30 itself are problems if the user has correct authorizations.
    Infact, if a user must view / maintain a table, it is much safer and cheaper to use SE16 / Sm30 than re-invent them and hardcode the table name.

  • License for testing and production systems

    Hi Experts
    Can any one help me out on implementing license in my B1 System.
    According to our contract we have licensed following user types:
    User Type
    Licensed
    AddOn Access License    25
    Professional User                5
    Software Development Kit - Development Version 20
    We have Test/development system in one hardware and Production system on different hardware. Please advice me how to request/allocate license for my test/development system and production system.
    We tried creating a Test System in SAP Market place and requested license for test system. While requesting license for production system, it is found that the license is exceeded. In other words, developent system license also counted.
    Please advice me on the best practices of B1 license implementation.
    Thanks and regards
    Ajith G

    Hi,
    Our customer wants to Keep the production data secure. Developers and consultants should not have the access to it.
    Then you have only two options:
    1.Either you should maintain a standalone b1 server for the developers and consultants to test their solutions and scenarios.
    2.Otherwise you can create users in sql studio for accessing only the test database.
    So that as per your requirement
    All configurations and sample data will be kept in a test environment where developers and consultants can do their work.Once everything is correct Admin will do the transfer to production.
    Note:New users can be created in the sql studio under Databases-><Company Db>->Security->Users, Rt.click new user

  • Technical Monitoring one template used for production and non-production system.

    Dear All,
    Is there a way to have one template in Solman Technical Monitoring for production system and non-production system with different alerts ? For example if it exceeds a threshold for production system it will trigger red alert or set automatically an incident and if it's non prod system it will go to yellow warning alert ?
    Regards
    Lukasz Goral 

    Hi Likasz,
    You first create and customize the template, and then assign to a system.
    If it was selecting a system and then customizing a template, then may be such functionality makes sense.
    So, I don't think that is possible.
    Better would be copy the template used for production to non-production and make the adjustment to it.
    Regards,
    Divyanshu
