About oracle 11g

One of the new feature about oracle 11g is continuous query notification. Where can I find the detail information about it?

On the 11g new features manual it states:
"1.1.6.4 JDBC Support for Continuous Query Notification
This feature allows Java Applications or Containers to subscribe to SQL queries watch list in the database and be notified when:
* DML or DDL changes affect the objects associated with the queries, or
* DML or DDL changes affect the result set
The notifications are published when the transaction (DML or DDL) commits.
Java Applications and Container prevents unnecessary database querying and implements efficient and consistent result set caching and cache invalidation."

    Hi
    Partition is Product Code It's Only allow to insert the values is 101 or 201Yes.
    Subpartition is State_code It's Only allow to insert the values is CT or NYNo. You have a subpartition with "default" and, therefore, any varchar2(2) value can be inserted.

  • Newbie question about Oracle 11G performance

    I have a situation where a newer better faster server running Oracle 11gR1 is running considerably slower than an older slower server running Oracle 10gR2.
    Both of these servers have the same web applications and same dumpfiles loaded into them.
    I personally installed the Oracle 11g on the new server, however, I didn't install the 10gR2 on the older server, some one else did...
    I have checked what I think are the basics: the tables are not missing constraints, the automatic memory management is enabled.
    I know this is a really broad question.
    Newer server:
    Quad-Core AMD Opteron Processor 2352 2.10 GHz (2 processors)
    16 GB memory
    Windows Server 2008, 64 bit
    Raid 5
    Older Server:
    Intel Xeon 1.8 GHz (2 processors)
    4 GB memory
    Windows Server 2003, 32 bit
    Raid 5

    Hi Derik,
    I know this is a really broad question. No, it happens all the time! Here is a similar issue:
    http://blog.tuningknife.com/2008/09/26/oracle-11g-performance-issue/
    +"In the end, nothing I tried could dissuade 11g from emitting the “PARSING IN CURSOR #d+” message for each insert statement. I filed a service request with Oracle Support on this issue and they ultimately referred the issue to development as a bug. Note that Support couldn’t reproduce the slowness I was seeing, but their trace files did reflect the parsing messages I observed."+
    I would:
    1 - Start by examining historical SQL execution plans (stats$sql_plan or dba_hist_sql_plan). Try to isolate the exact nature of the decreased performance.
    Are different indexes being used? Are you geting more full-table scans?
    2 - Migrate-in your old 10g CBO statistics
    3 - Confirm that all init.ora parms are identical
    4 - Drill into each SQL with a different execution plan . . .
    Raid 5 Don't believe that crap that all RAID-5 is evil. . . .
    http://www.dba-oracle.com/t_raid5_acceptable_oracle.htm
    But at the same time, consider using the Oracle standard, RAID-10 . . .
    Hope this helps . . .

  • Regarding ASM in Oracle 11g

    Hi
    I would like to use ASM storage for my single instance oracle 11gR2 database. I am a little bit confused so that asking some question about Oracle 11g ASM.
    1. Does Grid Infrastructure mandatory for installation Oracle 11g  ASM instance?
    2. Without installation Grid Infrastructure can I full fill my requirements ?
    Regards
    Rabi

    "If you plan to use Oracle Restart or Oracle Automatic Storage Management (Oracle ASM), then you must install Oracle Grid Infrastructure before you install and create the database. " -- http://docs.oracle.com/cd/E11882_01/install.112/e47689/oraclerestart.htm#LADBI999

  • Oracle 11g ASM - looking for some answers

    Hello,
    I reviewed a bunch of stuff about Oracle 11g ASM from various sources, but still haven't figured out some answers. Perhaps someone could help me to find the missing links please.
    Q1) ASMLib seems to require partitions. ASM recognizes partitions as well as disk devices. So why not using partitions in general? At least I could use ASMLib later without having to reconfigure the drives and loosing all data. Correct?
    Q2) The ASMLib driver is not installed by default, and unlike other ASM components is not available from the public yum repository for OEL 5.5. After some searching I found it available for download, but why is it not more obvious. Should it not be used anymore? http://www.oracle.com/technetwork/topics/linux/downloads/rhel5-084877.html
    Q3) ASM will not see drives or partitions unless the device ownership is set to Oracle. When Enterprise Linux starts, it resets all block devices to the owner of root. The solution is to create a udev rules file: e.g.:
    /etc/udev/rules.d/99-oracle.rules:
    KERNEL=="sda", OWNER="oracle", GROUP="dba", MODE="0660"
    KERNEL=="sdb", OWNER="oracle", GROUP="dba", MODE="0660"
    Before using ASMLlib, I need to configure the driver, which will ask me for the default user and group who owns the partitions (/etc/init.d/oracleasm configure)
    I conclude that using ASMLib will therefore not require a udev rules file, correct?
    Q4) The Oracle documentation outlines that ASMLIB is an application programming interface (API) developed by Oracle to simplify the operating system–to-database interface and to exploit the capabilities of vendors' storage arrays on Linux-based systems. What does this mean, examples? Isn't this what ASM does in general, why ASMLIB?
    Q5) I installed ASM and would like to re-configure it. Apparently ASM alone does not provide an interface other than sqlplus. In order use ASM with Enterprise Manager, I need to install a database or EM 11g (?) Grid control. Correct?
    Thanks,
    Markus

    Hi,
    So you got answers for 3 4 and 5
    Q1) ASMLib seems to require partitions. ASM recognizes partitions as well as disk devices. So why not using partitions in general? At least I could use ASMLib later >without having to reconfigure the drives and loosing all data. Correct?Using ASMLib, you can use your understandable disk partitions names rather than creating raw devices and adding entry in /etc/raw file and changing rights on every startup, so it makes life easier. Read post of "wcoekaer" from following thread
    ASMLib and Linux block devices
    Q2) The ASMLib driver is not installed by default, and unlike other ASM components is not available from the public yum repository for OEL 5.5. After some >searching I found it available for download, but why is it not more obvious. Should it not be used anymore? http://www.oracle.com/technetwork/topics/linux/downloads/rhel5-084877.html
    I am not sure about OEL 5, but i have seen it in OEL 4 and i can install this package during OEL 4 installation. But i believe you should be able to find this package in one of the Disks of OEL 5

  • Help Apply Patch to Oracle 11g

    Hello!
    Currently I have a single stand alone server (RHEL 5.8 Linux) running Oracle 11.2.0.1. I'm being told that the latest patch level is 11.2.0.3. I would like to get my current production database patched / updated to the latest version so I was told to do a "Out-of-place" manual upgrade from 11.2.0.1 to 11.2.0.3. In generic online tutorials and documentation, here is what I did. Currently my $ORACLE_HOME on Linux is:
    echo $ORACLE_HOME
    /oracle/u01/app/oracle/product/11.1.0/db_1
    I've downloaded the 1st two zip files for 11.2.0.3. I'm told that this will basically be a fresh / new installation of Oracle 11.2.0.3 on my server but installing in a new directlry structure or $ORACLE_HOME.
    So I create the following new $ORACLE_HOME path on my existing production server:
    /oracle/u01/app/oracle/product/11.2.0/db_1
    Here I extracted the 1st two .ZIP files for 11.2.0.3. Once the two files were successfully extracted, I now had a sub-sirectory called $ORACLE_HOME/database and in this new 'database' folder I see the 'runInstaller' script to kick off the OUI (Oracle Universal Installer).
    I walked through the failrly straight forward installer process and it said it completed successfully but now I'm confused on how or what methods do I need to take to migrate the data from my current $ORACLE_HOME to the newly created one. I know virtually nothing about Oracle 11g database systems but I'm eager to learn. I've used Google for most of my help with the exeption of some other forums. Can someone please help me with the correct / best way to finish the upgrade? So far I just installed Oracle over again on the same server just under a new folder path. The database listener and everything is still pointing to the 11.2.0.1 installation. I'm guessing I either have to use RMAN backupset from the 11.2.0.1 and recover it to the 11.2.0.3 install or perhaps there's some kind of migration step(s) / process.
    Sorry if this seems very basic or well documented for most but I couldn't find any info and or perhaps the lingo was over my head. I appreciate any supprt and or info in helping me. If you can, please note that this is my production server and it's an Enterprise stand-alone database server so if I need to take the database down or offline, please be specific in the steps needed as I have NEVER done anything like this before. I do have daily backups that I run manually using RMAN but I'd like to avoid using those at all cost unless it's required.
    Thank you in advance!

    Hi Carl,
    If you want to have your current database 11.2.0.1 to be upgraded in out of place.
    first being safe is better take a backup of the current database.
    As you have installed software 11.2.0.3 in out of place from previous home directory,
    Now using DBUA you can upgrade your database.

    Is this possible to do - so I can learn about Oracle 11g R2 RAC operation, tuning, setup and maintenance?Yes, possible to setup.
    No, you are unlikely to learn anything of value ito tuning and maintenance as the environment does not run on actual cluster h/w that are used in real world RAC clusters. For example, huge pages, jumbo frames - pretty meaningless in a VM for tuning Oracle RAC. Bonding of Interconnect Interfaces and pulling the plug - pretty much useless. What about running multiple I/O paths to the cluster's storage server? Using RDS for Interconnect instead of UDP? Etc. Etc.
    RAC is only as performant, scalable and robust as the h/w components it is build on. I cannot see any value in virtualising this and expecting to gain real insight to RAC performance management and tuning. Best one can expect is familiarisation with installation prerequisites, the installation steps and setting up the database. I question if any more value than that can be obtained from a single PC virtualised RAC environment.

  • Concept about Query Scn in Dataguard in Oracle 11g

    What are the details concepts behind the’ query scn’ in Dataguard in Oracle 11g. I read the concept from Oracle Datagaurd 11g Handbook but it was not clear for me.

    It's the highest SCN to which data is synchronised between the primary and secondary in a way that the secondary guaranteed read-consistent. It's therefore not possible to query an active standby for data modified after that SCN. At any given time, there might be transactions committed on the primary but not yet shipped or applied to the standby. You're not allowed to see those on the secondary. Not sure how much more detailed you want to get, really.

  • About memory issue during installing Oracle 11g on Windows Server 2003

    Hi, all
    When I installed Oracle 11g on Windows Server 2003 which the server is a virtual server, Oracle only can detect 2G memory.
    But there are 4G memory with my server.
    I want to know if the Oracle 11g's new feature or the virtual server lead the issue.
    Also , I want to get your help to resolve the issue, thanks a lot.

    Let me get this straight:
    You have created some virtual machine using someone's unknown VM software.
    You have installed Windows Server 2003 (perhaps, but not confirmed 32-bit) to that VM.
    You have allocated 4GB of memory to the VM (we guess ... not sure I'm ready to take your word on this)
    You are attempting to install Oracle 11g (presumably 11gR1 32 bit for Windows) in the VM
    And the Oracle (installer?) seems to be reporting that you only have 2GB RAM.
    Since I personally have installed Oracle 11g 32bit for Windows on Windows 2003 server with 4GB RAM and had no issues, I would be investigating the (unknown) VM environment.

  • Installation of Oracle 11g Release 2 on Windows Server 2008 R2

    Hi:
    When I tried to install 64-bit Oracle 11g Release 2 on a system running 64-bit Windows Server 2008 R2.
    One of the system pre-requisites failed with the following error message:
    Checking operating system requirements ...
    Expected result: One of 5.0,5.1,5.2,6.0
    Actual Result: 6.1
    Check complete. The overall result of this check is: Failed <<<<
    Problem: Oracle Database 11g is not certified on the current operating system.
    Recommendation: Make sure you are installing the software on the correct platform.
    I presume 6.0 is Windows 2008 Server and 6.1 should be Release 2.
    Does this mean that this version is not compatible with Server 2008 Release 2?

    I was just hoping there was an official release date and I just couldn't find it.
    Is there any information about features in 11gR2 for Windows available yet?
    Or can you maybe tell me if it will be possible to mount the new "database filesystem" like we can do on linux?

  • Problem with Application Login after upgrading to Oracle 11g

    I have a home-grown application with Oracle 10g database running under Windows XP Pro. Recently, I installed Oracle 11g and imported the application database from 10g to 11g (still want to keep the 10g running for a while). However, I now having problem with the application logging into the new 11g database. (Keep getting invalid user/name message).
    BTW, I have no problem accessing the 11g database through SQLPlus (logging in with the same name and password that I use for the application), and the connection test of NetManager (again using the same name and password that I use for the application) was successful.
    The application itself uses the old Borland BDE (Borland Database Engine) to access the 10g and 11g database. Testing confirms that BDE can access Oracle 11g with no problems.
    Any idea about the probable cause(s) of the problem?
    Thanks in advance,
    sg2000

    11g by default is case sensitive username/password.
    You can disable that with setting parameter SEC_CASE_SENSITIVE_LOGON to false.
