Using the Database Resource Manager

Hi,
in 10g R2,
I have never used DBMS_RESOURCE_MANAGER. I have some questions about it :
1-once activated by setting RESOURCE_MANAGER_PLAN = mydb_plan, would it work automatically ?
If not :
2-when a DBA switch a user ?
3-if he does it when a user consumes many CPU, how can DBA see that ?
Thanks.
Any link to articles explaining use of DBMS_RESOURCE_MANAGER would be appreciated.

  • Database resource manager and RAC

    Hello,
    This is probably is very simple question, but...
    I have a system with mixed workloads (OLTP and BATCH). As many before, I want to prevent BATCH processes from impacting OLTP. I read about RAC and DRM, and how each could be used to assign resources to services.
    Do I need RAC to be able to use DRM? Or can I do DRM without RAC? Are they the same thing?
    Thanks in advance for your help.

    DRM provides control over resource management decisions on both oracle standard and clustered databases.
    pecifically, using the Database Resource Manager, you can:
    * Guarantee certain users a minimum amount of processing resources regardless of the load on the system and the number of users
    * Distribute available processing resources by allocating percentages of CPU time to different users and applications. In a data warehouse, a higher percentage may be given to ROLAP (relational on-line analytical processing) applications than to batch jobs.
    * Limit the degree of parallelism of any operation performed by members of a group of users
    * Create an active session pool. This pool consists of a specified maximum number of user sessions allowed to be concurrently active within a group of users. Additional sessions beyond the maximum are queued for execution, but you can specify a timeout period, after which queued jobs will terminate.
    * Allow automatic switching of users from one group to another group based on administrator defined criteria. If a member of a particular group of users creates a session that executes for longer than a specified amount of time, that session can be automatically switched to another group of users with different resource requirements.
    * Prevent the execution of operations that the optimizer estimates will run for a longer time than a specified limit
    * Create an undo pool. This pool consists of the amount of undo space that can be consumed in by a group of users.
    * Limit the amount of time that a session can be idle. This can be further defined to mean only sessions that are blocking other sessions.
    * Configure an instance to use a particular method of allocating resources. You can dynamically change the method, for example, from a daytime setup to a nighttime setup, without having to shut down and restart the instance.
    * Allow the cancellation of long-running SQL statements and the termination of long-running sessions.

  • Database Resource Manager CPU levels

    Hi,
    I'd like to employ the Database Resource Manager to limit some user's sessions to a certain amount of CPU. After reading the documentation and an Oracle white paper, I'm still not clear on the difference between splitting the CPU allocation at level 1 to 70% and 30% or splitting the CPU allocation 70% at level 1 and 100% at level 2.
    Any clarification would be greatly appreciated.
    Regards,
    Jure

    what white paper did you read ??
    did you had a chance to look at oracle docs ??

  • Over of using Database Resource Manager

    Hi All,
    I am currently, doing a research on Database Resource Manager for implementing it in one of the Warehouse project database. Before, implementing it I would like to know few things. My Question is:
    Q. Does using Database Resource Manager cause any overhead? Any extra background process? any extra CPU Usage overhead? Any resource cost of using Database Resource Manager? Does it have any impact on resources and does it impact performance of the database?

    Hi Madrid,
    Thank you for your reply. Currently, we are looking into to implement Resource Manager in a dataware house environment because there are some ad-hoc users who execute really bad queries which puts lot of load on the database server which in turn slows down the performance. And there are few other reasons too. I not the primary for that environment though. This Resource Manager came up we thought that it might help us in controlling the ad-hoc users bad queries and also the environment.
    I have one more question in regards to resource manager. I have written a shell script which generates a report for stats of a resource plan from V$RSRC_CONSUMER_GROUP - which has stats data. But my concern is it stores historical stats too. For example, I have implemented resource manager and ran some queries and generated report and terminated all the sessions.
    Next day when I again run some queries and generate a report it gives stats combined with previous days stats. Is there any solution for this? So, that I can generate a report for stats at a point of time. For OEM I can reset the stats and get most current stats but this is not the case with the view I mentioned above. Please let me know if there is any other alternative for this. Hope you got my question.

  • What are the database resources when collecting stats using dbms_stats

    Hello,
    We have tables that contain stale stats and would want to collect stats using dbms_stats with estiamte of 30%. What are the database resources that would be consummed when dbms_stats is used on a table? Also, would the table be locked during dbms_stats? Thank you.

    1) I'm not sure what resources you're talking about. Obviously, gathering statistics requires I/O since you've got to read lots of data from the table. It requires CPU particularly if you are gathering histograms. It requires RAM to the extent that you'll be doing sorts in PGA and to the extent that you'll be putting blocks in the buffer cache (and thus causing other blocks to age out), etc. Depending on whether you immediately invalidate query plans, you may force other sessions to start doing a lot more hard parsing as well.
    2) You cannot do DDL on a table while you are gathering statistics, but you can do DML. You would generally not want to gather statistics while an application is active.

  • DATABASE RESOURCE MANAGER ( ORACLE 8I NEW FEATURE )

    제품 : ORACLE SERVER
    작성날짜 : 2004-08-16
    DATABASE RESOURCE MANAGER ( ORACLE 8I NEW FEATURE )
    ===================================================
    SCOPE
    8i~10g Standard Edition 에서는 Database Resource Manager 를 지원하지 않는다.
    Explanation
    Database Resource Manager란 OS에서 제공하는 자원 (예 : CPU 자원 )에 대해 DB
    차원에서 계획을 세워, 세부 관리를 할 수 있도록 해 주는 서비스이다.
    예를 들어 주간에 batch 작업을 처리하더라도, OLTP 업무에는 지장을 주지 않아야
    할 경우 batch 작업에 CPU 자원을 적게 할당해 주는 것이 바람직 하며, Resource
    Manager를 활용하여 CPU 자원을 batch 작업과 OLTP 업무에 서로 다르게 할당해 줄
    수 있다. ( Oracle 8.1.6 까지는 Resouurce Manager에서 CPU 자원에 대해서만
    관리만 가능하다 )
    1. 용어
    1) Resource Consumer Group
    사용자 session들의 집합. Resource에 대한 요구사항에 따라 나뉘어진 그룹.
    2) Resource Plan
         Consumer Group에 자원을 할당 해 주기 위한 resource plan directive들을
    포함.
    3) Resource Allocation Method
         Resource Manager에서 자원을 할당해 주는 방법/정책.
    4) Resource Plan Directive
         Resource Plan에 대해 자원을 할당해 주는 세부 내역.
    2. Resource Consumer Group
    * 기본 group
         [ 사용자가 삭제, 수정할 수 없는 group ]
         OTHER_GROUPS : active plan schema에 속하지 않는 consumer group의 모든
    session
         DEFAULT_CONSUMER_GROUP : consumer group을 지정하지 않은 모든
    session.(default)
         [ 기본적으로 제공되나 사용자가 삭제하거나 변경할 수 있는 group ]
         SYS_GROUP : SYSTEM_PLAN에 대한 high priority consumer group
    SYSTEM, SYS user에 할당한다.
         LOW_GROUP : SYSTEM_PLAN에 대한 low priority consumer group
    3. Resource Plan
         Consumer group에 속하는 session들은 해당 group에 대한 resource plan에
    따라 자원 할당이 결정되며, 자원 할당에 대한 세부 사항은 resource plan에
    대한 resource plan directive에서 지정된다.
         Resource plan은 subplan을 둘 수 있다.
    4. Resource Allocation Method
         Round-robin Method : Consumer group 내에서 session들에 대한 CPU 할당
         Emphasis Method : Consumer group에 할당되는 CPU
         Absolute Method : Parallel degree 한계 ( 예 : Parallel Query에서의
    degree )
    5. Resource Plan Directive
         Resource Plan Directive에 지정된 내용들은 resource plan에 따라
    consumer group에 자원을 할당할 때 반영된다.
    6. 구현 예제
         MYDB PLAN +-> MAILDB PLAN +-> POSTMAN GROUP (40% Level 1)
         | (30% Level 1) |
         | +-> USERS GROUP (80% Level 2)
         | |
         | +-> MAILMAINT GROUP (20% Level 2)
         | |
         | +-> OTHER GROUP (100% Level 3)
         |
         +-> BUGDB PLAN  +-> ONLINE GROUP (80% Level 1)
         (70% Level 1) |
         +-> BATCH GROUP (20% Level 1)
         |
         +-> BUGMAINT GROUP (100% Level 2)
         |
         +-> OTHER GROUP (100% Level 3)
         위 예에서 MYDB PLAN에는 2개의 subplan ( MAILDB PLAN, BUGDB PLAN )이
         있으며 각각 30%와 70%의 CPU 자원을 할당하였다.
         Level 1, Level 2, Level 3 는 우선순위 레벨을 의미하며, 하나의
         resource plan에서 동일한 level의 합이 100%를 넘지 못한다.
         ( Level 은 1부터 8까지 지정할 수 있으며 level 1이 가장 우선순위가
         높으며 level 8이 가장 우선순위가 낮다 )
         예를 들어 전체 CPU 자원의 70%를 할당 받은 BUGDB PLAN은 다시
         ONLINE GROUP과 BATCH GROUP을 두고 있는데, 이 둘의 Level이 모두 1이며
         두개의 percentage의 합이 100%이다. 하지만, 즉, level 1인 ONLINE GROUP
    에 90%를 할당하였다면, level 1인 BATCH GROUP에는 10% 이상을 할당할 수
    없다.

  • Vista: use the windows program manager to execute operating system commands

    attempting to run forms 6 on vista... the forms app attempts a call sqlplus using the host builtin to populate some tables before calling the report.
    in windows vista i get a message box indicating "use the windows program manager to execute operating system commands".
    is this windwos vista message? would this have to do with permissions?
    any insight most appreciated and thanks in advance.

    I don't know about the HOST-problem, but..
    the forms app attempts a call sqlplus using the host builtin to populate some tables before calling the report.What about putting the logic from the SQL*Plus-scripts into a database-procedure and call that instead. I think,, with the current approach you will get problems at least when you have to migrate to Web (e.g. Forms 10g).

  • Does Oracle Database Resource Manager work at all?

    I have been testing Oracle Database Resource Management...
    Environment: OS IBM AIX 5L 64 bit core, DB Oracle8i 8.1.7.4 Enterprise Edition.
    To test, I followed the procedure in the Oracle Metalink Bulletin Note:106948., Oracle8i: Database Resource Manager samples.
    But I was not able to reproduce any succes. There seems to be no difference running with at plan and not running with af plan enabled.
    Does anydody know of a problem with the combination of Oracle and AIX, or any other problems that could explain why it doesn't work?

Working with Captivate App Packager the pane to import from Adobe Edge is missing, so not clear how to import. Overall it seems unstable. Am I doing something wrong?

    Hi Vikram and Lilybiri,
    Thanks for your responses :-)
    I'm working on Windows 8.1... I think that I may have found the issue... I was saving the file in a project directory rather than the default My Captivate Projects folder...
    Perhaps Captivate was struggling to find resources it needed?
    It hasn't crashed for a while now, though it is struggling - I'm working with a 54 slide PPT presentation that is linked and it takes a very long time to interact.
    Sometimes it says that I've removed slides, which I haven't?
    Best,

  • How can I delete a row in access using the database toolkit?

    I want to delete just one row of a access table using the database toolkit. Can it be done and if so How?

    Take a look at page A-1 of the database connetivity manual. It has information on making a sql query that will delete. You will need to use this command with the dbtools execute query function. Look in the shipping examples for an example with this function.

    Is there any issue with the set or definition that I get the above error?

    What is the version of the Oracle database in which you have specified/and use the database link?
    If it is for example 10.2.0.3.0 you need to apply the mandatory patch for RDBMS bug 5965763 first before being able to use an 11g gateway. Have a look at MetaLink note 457808.1 for details about this patch.

  • When using the Database Connectivity Toolset, reads and writes with long binary fields are incompatible.

    I am trying to write LabVIEW Variants to long binary fields in a .mdb file using the Database Connectivity Toolset. I get errors when trying to convert the field back to a variant after reading it back from the database.
    I next tried flattening the variant before writing it and ultimately wound up doing the following experiments:
    1) If I use DB Tools Insert Data to write an ordinary string and read it back using a DB Tools Select Data, the string is converted from ASCII to Unicode.
    2) If I use DB Tools Create Parameterized Query to do an INSERT INTO or an UPDATE operation, specifying that the data is BINARY, then read it back using a DB Tools Select Data,
    the length of the string is prepended to the string itself as a big-endian four-byte integer.
    I can't think of any way to do a parameterized read, although the mechanism exists to return data via parameters.
    Presuming that this same problem affects Variants when they are written to the database and read back, I could see why I get an error. At least with flattened strings I have the option of discarding the length bytes from the beginning of the string.
    Am I missing something here?

    David,
    You've missed the point. When a data item is flattened to a string, the first four bytes of the string are expected to be the total length of the string in big-endian binary format. What is happening here is that preceding this four-byte length code is another copy of the same four bytes. If an ordinary string, "abcdefg" is used in place of the flattened data item, it will come back as <00><00><00><07>abcdefg. Here I've used to represent a byte in hexadecimal notation. This problem has nothing to do with flattening and unflattening data items. It has only to do with the data channel consisting of writing to and reading from the database.
    I am attaching three files that you can use to demonstrate the problem. The VI file c
    ontains an explanation of the problem and instructions for installing and operating the demonstration.

  • Can I use the database toolset within a fieldpoint vi?

    I want to be able to read and write to a database on our network using the database toolset. My vi works under windows but does not under fieldpoint. (does not run at all). I've included (loaded) the template while building the executable. As well I've include the udl support file to access the database

    Ola,
    If I was designing this system I would use a shared variable which contains the name of the last data file written by the FieldPoint.  The PC would monitor that name and when it changes, use the FTP VIs to download it to the PC.  The PC VI would then parse the text file and insert into the SQL database.
    Using a lock file or a Boolean Data Ready? flag would also be very valid approaches.
    Depending on how fast you are acquiring data you might be able to do away with the intermediate text file.  Another possible approach would be to use the TCP VIs to effectively stream the data from the FieldPoint back to the PC where it can be inserted into the database.

  • I am not able to open iPhoto, when I have used the iPhoto Library Manager, I get the message that "the iPhoto Library folder could not be found" Help!

    Help!  I can't open the iPhoto!  I have os x 10.5.8 and I have tried using the iPhoto Library Manager only to find out that the folder for the iPhoto Library could not be found.
    I have also tried the Fix #1 from the user Old Toad who said to delete the preference file :com.appleiPhoto.plist - I could do that, but I couldn't figure out how to delete iPhoto's cache fie, Cache.db because I couldn't find it?  I'm not sure how to find the file by it's directory path name of HD/User/Home/Library/Caches/com.apple.iPhoto .
    Help is very much appreciated!

    Download and use  Find Any File  to search for "Library6.iPhoto".  It's a file that is present in every iPhoto library.  If you don't find one on your hard drive then your library has gone missing entirely. 
    Another thing you can try is to use the Search For - All Images feature in the Finder window to see if you can see any of your photos.
    That will tell you if they are on your hard drive but somewhere other than the library.
    What do you see when you insert the DVD into the optical drive?  Can you open it and any folders on the disk?  If the disk is titled iPhoto Library  then open the disk, the the iPhoto Library folder and finally the Originals folder.  Check the subfolders to see if your photos are there.
    Your original photo files will be in the Originals subfolders.
