LogMiner and a database with RAC

how do they work together?
how is the logging mechanism when the database is spread across multiple nodes?
does logminer need to connect to all nodes to reconstruct the ddl statements? or does logminer retrieve the data from all node by itself?
as far as i have read there is no real "supernode" which has all the meta data about the partitioned database. is that true?
thx.

Each instance has its own 'thread' of execution and writes to its own set of redo files.
All instances have access to all logs.

  • Problem to create database with RAC 10g with Oracle Standard Edition

    I install CRS (Cluster Ready Services), and then install Oracle 10g database. Also, I install patches 10.1.0.4. When I create database with ASM storage give me a error to create files database.
    Any idea?
    Thanks

  • Alert Log File Monitoring of 8i and 9i Databases with EM Grid Control 10g

    Is it possible to monitor alert log errors in Oracle 8i/9i Databases with EM Grid Control 10g and EM 10g agents? If yes, is it possible to get some kind of notification?
    I know that in 10g Database, it is possible to use server generated alerts, but what about 8i/9i?
    Regards,
    Martin

    Hello
    i am interested in a very special feature: is it possible to get notified if alerts occur in alert logs in an 8i/9i database when using Grid control and the 10g agent on the 8i/9i systems?
    Moreover, the 10g agent should be able to get Performance Data using the v$ views or direct sga access without using statspack, right?
    Do you know where I can find documentation about the supported features when using Grid Control with 8i/9i databases?

  • Can I have a primary database and standby database with a different windows version?

    Hi
    I need your help.
    We need to increase the memory in the server where is the standby database , but first, we need to upgrade the windows version.
    The actual version is windows 2003 standard edition 64 bits
    The new version will be windows 2003 enterprise  edition 64 bits
    This difference in windows version  between primary and standby servers can cause a problem in the synchronization between primary and standby databases ??
    What do you recommend? Have both servers in the same windows version?
    The databases are in SQL SERVER 2005.
    Thanks.
    Loreinn

    This difference in windows version  between primary and standby servers can cause a problem in the synchronization between primary
    and standby databases ??<o:p></o:p>
    There is no issue with database synchronization as long as SQL Server is of same version.<o:p></o:p>
    What do you recommend? Have both servers in the same windows version?<o:p></o:p>
    OS(Windows version) has no restriction for using SQL server 2005 database mirroring/log shipping. You can go with upgrade without any worries on SQL
    database side.<o:p></o:p>

  • Same user in tacacs and local database with different privilege

    Hi there,
    i am just not sure if this is correct behavior.
    i am running NX-OS image n5000-uk9.5.1.3.N1.1.bin on the nexus 5020 platform.
    i have configured authorization with tacacs+ on ACS server version 5.2 with fall back to switch local database.
    aaa authentication login default group ACS
    aaa authorization commands default group ACS local
    aaa accounting default group ACS
    a user test with priv 15 is craeted on ACS server, password test2
    everything works fine, until i create the same username on the local database with privilege 0. ( it doesnt matter if the user in local database was created before user in ACS or after )
    e.g.:  
    username test password test1 role priv-0   (note passwords are different for users in both databases)
    after i create the same user in local database with privilege 0,
    if i try to connect to the switch with this username test and password defined on ACS,  i get only privilege 0 authorization, regardless, that ACS server is up and it should be primary way to authenticate and authorizate the user.
    is this normal?
    thank you for help...

    Hello.
    Privileges are used with traditional IOS. Privileges are part of "command authorization". Other operating systems (like IOS-XR, Nexus OS , Juniper JunOS) use "role-based authorization" instead of "command authorization".
    So traditional IOS can use the "privilege" attribute but other operating systems can not.
    Although IOS-XR, Nexus, ACE, Juniper  have "roled-based authorization" feature, every single one of them use their particular attributes.
    When I was configuring TACACS with ACE, Juniper and other devices I had to capture the packets to find out what were the particular attributes of ACE, what were the particular attributes of JunOS, etc, etc and to search deeply some hints the documentation , because sadly  documentation is not very good when talking about TACACS details.
    If you find which attributes to use, and what values to assign to the attributes then you can go to ACS and configure a "Shell Profile".
    Now back to Nexus 5000. It seems this particular device has the option to mix "role-based" with "command authorization" by overriding the default roles with other roles which names are called "priv". It seems this was an effort to try to map the old concept of "privileges" to the new concept of "roles". Although you see the word "priv", it's just the name of the role. My particular point of view is that this complicates the whole thing. I would recommend to use just the default roles, or customize some of them (only if needed), but not to use "command authorization".
    http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/security/502_n1_1/Cisco_n5k_security_config_gd_rel_502_n1_1_chapter5.html
    I will search the particular attributes Nexus use to talk to TACACS server. If I got them I will post them here.

  • Archive logs and recovering database with no RMAN

    Hello,
    I inherited a database with no RMAN backup activated but archive redo logs are activated and generating at every moment.
    As there is no rman backup I always thought that those archive redo logs were useless and because of reduced disk space, regularly I delete all of them.
    Then I read that archive redo logs can be usefull even if there is no RMAN. Archive redo logs can be used in a recovery situation like this:
    set all tablespaces in backup mode
    alter tablespace tsp1..tsp100 begin backup;
    copy all datafiles
    alter tablespace tsp1..tsp100 end backup;
    alter database create standby controlfile as 'c:\temp\sbytemp.ctl';
    copy of archivelogs from start begin backup time till nowAs I delete my archive logs, I don't have all ones from the first time. My question is:
    How many archive redo log files would I need to have? Would I need to have all archive logs that were generated from the first time? Or would be enough to have the last three or four ones?
    Thanks
    Edited by: user521219 on 21-may-2012 7:50

    How many archive redo log files would I need to have?
    Would I need to have all archive logs that were generated from the first time?
    would be enough to have the last three or four ones?You need all archive redo log from the moment you have started taking full backup.
    If you take full backup every night at 1:00 AM, you will need all archive redo logs that have transactions finished at and after 1:00 AM.

  • Sql 2005 standard edition for sql and AS databases with bpc 7.0 sp3 ?

    hello
    Install guide tells that we must use SQL 2005 Enterprise Edition with BPC except for Reporting Services.
    Customer asks wether he could use SQL 2005 Standard Edition for SQL database and Analysis Services ?
    Thanks.

    Hello Sorin. Two more questions, please:
    1) what do you mean by "Also into Application server you need EE because only in this version you have control flow." ?
    Is "control flow"  "business process flow" new functionality ?
    2) On the other hand, I don't think that BPC admin task is able to handle lite or full optimize without an Enterprise Edition Client.
    But customer asks wether it is possible to install on application server
    - SSIS standard edition for SSIS service
    - SSRS standard edition for Reporting Services
    - SQL client Enterprise Edition to let BPC admin task handle lite and full optimize properly.
    Why all this ? Because Enterprise Edition costs ten times more than Standard Edition and in a multi-server configuration, customer has to buy several SQL Server licenses, one per server running at least one SQL server service. (For example, with SQL,SSIS and OLAP on one server, and SSIS and SSRS running on the application server, customer has to buy two SQL servers licenses).
    Thanks. R.

    Yea, i do the same thing, but i see that some people want to receive mail that other people don't want.
    Can i ask you another question? How do you deploy sa-learn?
    I use this scripts:
    learn_nospam.sh
    dir_nospam='/mail_store/*/*/*/\=no_spam/*/*.msg'
    for i in $dir_nospam
    do

    do
    echo $i
    sa-learn no-sync spam $dir_spam

    That 's works but it too slow, do you know some other ways.

  • Free and huge database with city coordinates

    I write a web application where the user must be able to search for people which live for instance 50 miles around his city.
    So I need a database which contains city names, zip codes and the coordinates for the cities or zip codes. Or maybe there is a free web service which I can call and get the results?
    I've seen that there are web services for this. But they need to be payed. I want something free, either a free web service or free data. There is also a free geo data project. But it is limited to Germany and doesn't seem to be well maintained.
    The whole thing should work primarily for the German area: Germany, Austria and Switzerland. But it should also work for the world, although it will become important much later.
    How do you solve this problem without paying for a professional service or paying for professional data? Or, if you pay, what company has the best to offer in terms of completeness of cities worldwide?

    maybe adaptable,

  • Oracle Clustre, Oracle Cluster with RAC and Oracle 10g

    Is there a difference between Oracle Cluster and Oracle Cluster with RAC? Please explain. Do existing database codes run unmodified in Cluster or Cluster with RAC environment? What needs to be modified to make existing SQL codes RAC-aware. How to achieve 'all automatic' in case of failure and resubmission of Queries from failed instance to a running instance?
    In 10g environment, do we need to consider licensing of RAC as a separate product? What are additional features one derives in 10g that is not in Cluster +RAC?
    Your comments and pointers to comparison study and pictorial clarification will be very helpful.

    Oracle cluster like failsafe before or Veritas Cluster or other vendor's cluster is meant for HA (high availability) purpose. Which 2 nodes or more can see a shared disk with 1 active node. Whenever this active node failed through heartbeat other machine will know and will take the database over from there.
    Oracle RAC is more for HA and load balance. In Oracle RAC 2 or more nodes are accessing the database at the same time so it spread load across all these nodes.
    I believe Oracle 10g RAC still need seperate license for it. But you need to call Oracle or check the production document to verify it.
    Oracle 10g besides improvement in RAC. It's main improvement is on the build in management of the database itself. It can monitored and selftune itself to much furthur level then before and give DBA much more information to determine the cause of the problem as well. Plus improvement on lots of utility as well like RMAN , data pump etc... I don't want to get into too much detail on this you can check on their 10g new features for more detail view.
    Hope this help. :)

  • Best way to manage 8i and 9i databases?

    Hi,
    I'm looking for the best way to manage 8i, 9i, 10g and 11g databases with EM (of course, upgrading the 8i databases is not an option). I successfully installed OMS 12c, but the 12.1 agent will not connect to the 8i databases. What are the alternatives?
    -The 10g agent can manage 8i, but will it be able to connect to 12.1 OMS?
    -If this doesn't work, I guess I would need a 12.1 OMS for 9i, 10g and 11g databases, and a 10g OMS for the 8i databases. Is this a viable solution? Can 10g and 12.1 OMS coexist within the same environment?
    I'm looking for the best scenario that actually works, I understand that anything that connects to 8i will not be supported.
    Thanks.

    Hi.
    I'm afraid you got it right.
    Let's distinguish between MONITORING- which is done by the agent and MANAGEMENT (administration, maintenance, performance management etc) - which is done directly from the OMS.
    According to my experience:
    OEM 10G is the last version that can fully MANAGE 8i databases.
    OEM 11G can MONITOR 8i databases (via a 10G agent) but cannot MANAGE them (or in other words ,the 11G OMS cannot connect to 8i databases).
    OEM 12C cannot MONITOR nor MANAGE 8i databases.
    If you use OEM to fully manage your 8i databases (and plan to continue doing so) I suggest you keep a dedicated OEM 10G installation for those databases.
    There's no problem using 2 different OMS installations and many organizations choose to do so for various reasons.
    The downsides are that you'll need to duplicate your OEM configurations (monitoring templates, rules etc) and of course- you won't be able to manage all databases in a single console...
    If you use OEM to only monitor the 8i databases, you can create a set of user defined metrics that will run against a 9i database and will connect to the 8i databases via DB Link.
    This solution is far from ideal but it might eliminate the need for maintaining another OMS installation if all you need is monitoring the 8i databases.
    Erez.

  • Upgrade database for RAC

    I have 11g standard edition database installed without RAC in a server environment. But, now I have needed to keep this database in RAC. Could I install or upgrade database with RAC environment without re-installation of oracle software/database from the scratch?

    depends
    you can relink the database home with RAC option on Linux/UNIX platforms: RAC Survival Kit: Rac On / Rac Off - Relinking the RAC Option [ID 211177.1]
    but not on Windows
    if you already have grid infrastructure (clusterware) configured as Oracle Restart, you can convert it to cluster configuration:
    http://docs.oracle.com/cd/E11882_01/install.112/e22489/rem_orcl.htm#CBHEEJAA
    otherwise you will have to install it (this can be higher version than your database home)
