Sun Solaris 10, Oracle 11gr2 x86 How are you doing? I am trying to build a test system. I never build ASM before. if I need to install database first then Migrating to ASM? The other problem I am having is that I only have a Raw disk. I have one disk for root and oracle and the other one for Raw disk for ASM. Do you know it's possible to build ASM on 1 raw disk?
I want to configure row device to usable for creating new asm diskgroup.we are using ASM. Steps to configure that row device to available for creating new diskgroup.
i am trying to create a flight booking system,i am at the stage of creating the tables but am having trouble with creating one of the tables
CREATE TABLE Seat (Seat_no NUMBER(3) CONSTRAINT PK_Seat PRIMARY KEY, Class_Code CHAR(2) CONSTRAINT FK_Class_Code FOREIGN KEY (Class_Code) REFERENCES Class(Class_Code) CONSTRAINTS CHK_Class_Code CHECK(Class_Code='EN' OR Class_Code='FS') (Class_Code is a primary key in the table Class)
It comes up with an error saying ORA-02253: Constraint specification not allowed here and if i put a coma after the first constraint it says the name already used for an existing constraint.

ERROR: ORA-12534: TNS:operation not supported
Enter user-name:
so I Google around for the solution to the ORA-12534 error, one of the site,
[URL].......
here's my lsnrctl services
Connecting to (ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1521)) Services Summary... Service "MIKEXDB" has 1 instance(s). Instance "mike", status READY, has 1 handler(s) for this service... Handler(s): [code].....
The command completed successfully
right now I think I will be a fool to think that the solution is to resolve the ERROR: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor. so what is wrong with my setup, or is it some patch that I need to apply?
The blocksize for my database is 4096, as i have heard that the minimum size of the datafile is decided by blocksize, but i want to know that how it is calculated as by giving the above syntax the other values will be default. I am trying the syntax in oracle 9.2.0.1.0 version.
I'm currently new to Oracle 10g SQL and I need to query a large library file.I need to find the different first keywords associated with references written by authors who have more than 10 references in the readings table.
In Oracle 10.2 installation there are OCI headers in rdbms/public directory: 10.2.0/rdbms/public/ocidem.h 10.2.0/rdbms/public/ocidfn.h 10.2.0/rdbms/public/ocikpr.h 10.2.0/rdbms/public/oci.h 10.2.0/rdbms/public/oci1.h ...
What should be installed additionally to have OCI headers in rdbms/public in Oracle 9.2.0?
my Multithread-Program hangs in an oracle library while passing a prepare statement (also if i try an EXEC SQL SELECT statement...). Something seems to be wrong in the Program, but i cant's find the Error.The Program is build with:
according to article "Installing Netbackup for Oracle agent on Unix". URL.... Shut Down all oracle instances on this client. The reason: sometimes Oracle will take a shared library (such as ours) and place it into its shared memory spaceMy question is how I can control existence shared library in memory space to define the real need of Shuting down of all oracle instances ? I'm usung 11.2.0.3
i have install 0racle 9i its working fine .I can access data from launch standalone but when i tried with login to oracle management server i can't login .
I'm looking for a basic password reset / unlock tool for use at a help desk. Environment is mixed 10 and 11G. Current procedure is log into specific database using SQL Plus and manually type out reset/unlock commands.
I have been reading various articles about the undo management. This basic concept of undo management is simple but how oracle implements it is bit harder for me to grasp.
What i have read and understood is that whenever a DML(Update, Delete, Insert) statement is issued by a user, the data is fetched from datafile to database buffer cache and at the same time a copy of the original data is saved in undo segment. Now if other users requests the same data, they are presented with the unchanged copy in the undo segment.
Now I have the following questions: 1) In case of Insert statement, what data is saved in undo segment. Is it the complete data in the table to which we want to insert the new row? 2)When the user issues DML statement, there are three copies of the same data, one in Memory (which is changed and not the same as original data), second in Undo segment (Which is unchanged copy of original data) and third in datafile file ( which is original data). What is the difference in the data in undo segment and data in datafile at this stage. Why are the other users presented with the data from undo segment rather than original data from the datafile to maintain read consistency. 3)When the user issues rollback, the changes made to the copy of data in memory are undone.The copies of data in memory and undo segment are now same?. What happens to the before change copy in undo segment. Is it still there or deleted.
I cannot start ASM on my Oracle Database Appliance.
crsctl status resource -t says: ora.asm ONLINE ONLINE node1 Started ONLINE ONLINE node2 Started
however, if I try to access the ASMCMD it says: [grid@node1 ~]$ asmcmd Connected to an idle instance. ASMCMD> startup ORA-00304: requested INSTANCE_NUMBER is busy Connected to an idle instance.
I am using 11.2.0.1.0 on RHEL 5.4ASM is properly working on my machine. database is running from ASM. I want to configure additional oracleasm devices.command fails saying:

I am creating asm diskgroup on loopback devicesHere are the configured loopback devices.

, I have a few doubts in Normal,High and External redundancy levels in ASM concept. External - No failure group. No mirroring. Normal - Two Way Mirroring. One failure group. High - Three Way Mirroring. Two failure group. 1.
above mentioned 3 types in correct.2. My main question is what is the minimum number of disks needed in Disk group creation in Normal and External redundancy??
couple of questions about below parameters, do they measure single processor or avg usage across all processorss and cpus for example will i recieve alert if CPU system time goes above 95% for single processors? or not
CPU Idle Time (%) CPU System Time (%) CPU User Time (%)
i try to install oracle grid infrastructure 11r2 on cent OS 4.8 on vmware workstation 8.0.2..ASM disk is not showing ,i had also change disk discovery path to 'ORCL:*'i had already configure ASM disk using /etc/init.d/oracleasm createdisk...successfully..
i have installed oracle 8i on my windows xp system. it has not given me any problems during installation. i could log on to oracle and work on it without any problems. but when i restarted my system, my system has failed to start the oracle service, and i could no longer logon to sql * plus.
I've got messages 'oracle not available'. i've even tried to start the service from administrative tools-services, but of no use. then i created a new database and log on to sql* plus. but when i rebooted my system, the problem continued.
Can I use OFA and Raid system together for Oracle 11g in Windows 2008 Server? I am installing the OS in C drive. Where to install the oracle, location for Oracle_Base, number of logical and physical drive required, size of each etc.
I am planning to use Raid 1 - Controlfile, redolog file and archive log file Raid 1+0 - Datafiles
Also I want to multiplex virtual memory page also.
I created an empty database using the DB Configuration Assistant, then imported a dump file provided by a client. I believe what happened is that all of the user passwords (for SYSTEM, SYSDBA, etc.) which I had created in the DB Config Assistant were overwritten during the import process as I can no longer log into the DB.
I have attempted logging into sqlplus using the /as sysdba swith while logged in to the server as a user in the ORA_DBA role, but I still get the ORA-01031: insufficient privileges message.
I have customized system on oracle 10g ( English interface and reports ) , the company want to make the system in both (Arabic and English) , i make every thing is okay , but the problem when i change the PDF subset in the file uifont.ali to include Arabic fonts , the report server every 2 hours stopped and give me the message ( server is in progress ) ,
