I have been implementing a script to change a lot of data in a database production.Because of this the database will be 100% dedicated to the execution of that script, in the sense that nothing else will be running in this period (the application will be stopped).
what can i do to improve performance of that execution? is there any oracle manual online for this type of problem? I do not know if it's possible, but I'm thinking of things like disabling locking mechanism (if possible I could run instead of a process many processes in parallel), disabling index growing (during the process), disabling constraints.
The documentation for v$database says: QUOTE V$DATABASE displays information about the database from the control file. Is it safe to assume that there will only ever be one row queried from this view?
Any problem using 4.2's One Level Tabs - Content Frame page where you have a parent region (of type content frame Body Container ) while number of child regions (of type Hide & Show Region - Borderless ), if you want to re-order them by changing the sequence, it has no effect when you run the page.
The regions still show in the same order top to bottom as it did before the update of sequences. Heading links (to show/hide child regons in content frames) has the same ordering as before.
I am having problem with my tnsnames.ora file.seems the file cannot handle connection information for more than one DB. It worked fine in the beginning, after that, whenever i had to connect to a DB, i had to keep switching and renaming 5 files, with respect to whichever database I want to connect to. this is the entries in the file, for 2 D's and it wont work, with just one in each it works, but not for two...
I am sure, nothing wrong with teh IP/virtualname, cause with just one of these in the file, they work excellent.I tried leaving line between the connection strings for each DB, without leavin lines, etc..
I have to design a database so that the performance is optimum and joins are optimum between tables.
Requirement - I have several banks as clients globally, like HSBC, RBS, AMEX etc. Each bank operate globally, and are divided like the geographies, regions etc. For eg. HSBC is operating from US, UK, ASIA, AUSTRALIA. Each geoagraphy is further divided/childs, like, in ASIA has INDIA, PAKISTAN, SRI LANKA, CHINA. Further, it is divided, like in India, it has cities like DELHI, BOMBAY, CHENNAI etc., then further it has within Delhi - Lajpat Nagar, Rohini, Pashim Vihar etc.
As per the above scenario, I need to store addresses, phone numbers, of all the branches of all clients. Also, there is one more condition like in the above defined hierarchy, later on, a new hierarchy can be added, like In INDIA, it can further divided in States and then its local cities.
When i am writing a function (Stand alone or inside a Package) i know what i am writing, i know weather i am changing a Package state or weather i am changing a Database State. So what is the use for giving a PRAGMA RESTRICT_REFERENCE?
as for the other PRAGMAs EXECPTION_INIT is needed to Specify an error name to a specifiec error number so that i can use the error name to handle the exception. AUTONOMOUS_TRANSACTION is used to execute the SQL Operation inside a Block as a child Transaction.SERIALLY_REUSABLE states that a package variable doesnot persists throughout the session.
RESTRICT_REFERENCE states that the code should not do the following RNPS : Read no package state, WNPS : Write no package state RNDS : Read no database state WNDS : Write no database state
what is there to state as i know what my code is doing.
without specifing EXECPTION_INIT, AUTONOMOUS_TRANSACTION or SERIALLY_REUSABLE i cannot get a handler for an exception which doesnot have a handler, i cannot execute SQL Operations from inside the CODE autonomously or i cannot reuse the package variable, but without the RESTRICT_ REFERENCE is can ensure that my code in not doing (RNPS,WNPS,RNDS,WNDS).
I'm using 2 databases : Primary and Standby DB. It working fine. I've just one question : I want to change SYS password on primary DB. Can I change it without any action on Standby DB?
I want to replace one redo log on the primary database. actually this redo log is on G:oracleoradata; I want to move it on F:oracleoradata. How to do that cause the same redo log is also on standby database?
I am developing some automated test packages for my PL/SQL Packaged code. Going forward I can code the test package in conjunction with the code but I have some historic packages that I would like to develop these test packages for.
To save time I would like to employ oracle data dictionary views in order to construct the framework for my test package. This includes using SQL to get a list of procedures / functions within the package in order to create the test procedures (spec and body). I can do this in a basic way using the user_procedure view with something like...
SELECT 'PROCEDURE test_' || LOWER(procedure_name) || ' (p_result OUT VARCHAR2 IS BEGIN JTA.ACCOUNT_PROFILE_MAINT.' || procedure_name || ' END ' || LOWER(procedure_name) || ';' FROM user_procedures WHERE object_name = 'ACCOUNT_PROFILE_MAINT' AND subprogram_id != 0 ORDER BY subprogram_id;
However, the above only really works (in simplistic form.. without parameters) for procedures within the package. I would also like to be able to determine if the procedure listed is actually a function or procedure (so that I can alter the syntax accordingly to generate a correctly formatted string calling the program unit).
So, initially how do I determine the type of package program unit I have (Proc/Function)? Do I need to go to all_source to get this information or are there other views available I can join to?
Eventually I would like to extend this to be able to automatically include any parameters in the generated calling string.. again, is there any other option apart from all_source to get this information?
The sqlcache is getting over-written.I would like to capture information from AWR snapshots and feed those (as a workload) into the DBMS_ADVISOR.I can't see where it's possible (other than manually creating my workload from AWR information)
How can i retrieve which tables have composite primary keys, and only one of the primary key columns is a foreign key to another table?
Like: CREATE TABLE club ( clubId NUMBER, name VARCHAR(20) NOT NULL, PRIMARY KEY (ClubId) );
CREATE TABLE team ( teamid NUMBER(10), clubid NUMBER(10), teamname VARCHAR(10) NOT NULL, PRIMARY KEY (teamid, clubid), FOREIGN KEY (clubid) REFERENCES club (clubid));So in this case, the team table
)How do you view the value of the parameter that is being used by instance? show parameter..? 2)How do you get the information of hidden parameters 3)What is the database object that stores information related to various types of db connections over network 4)How do you verify since when the db session is running 5)How do you verify the Originating machine details of the database session 6)How do you verify the name of program that the db session is running 7)What is the naming convenion of Base tables. Where is the information of base tables stored? 8)How are dynamic views created. Whre is the information of dynamic views stored?
We are running Oracle 10g. I need to pull the DDL information from our Oracle tables. The following SQL statement returns the result as a "HUGECLOB". Is there a way to convert the result to text in varchar2 data type? Since tables being processed have numerous partitions, the DDL information for them is quite large, therefore, using substring would not be a viable alternative.
[code]select DBMS_METADATA.GET_DDL('TABLE','EMPLOYEE') from DUAL; [/code]
Redo log information can be transmitted in one of two ways from the primary database to the standby database: either by ARCH or LGWR.
1. when ARCH involves 2. when LGWR involves FAL_Client = (Should i enter net service name or Db name or service_name FAL_Server = Should i enter net service name or Db name or service_name ) FAL_CLIENT='whichone'
Sequence nextval is a pseodocolumn, but where the value of nextval is stored and why before we use CURRVAL for a sequence in our session, we must first initialize the sequence with NEXTVAL?
Is there any way to capture the version wise objects (Packages) information from the oracle data base.
Ex : I have package P1 which was created on 01-NOV-2012 with version 1 . After 10 days same package has been updated version 2 with some enhancements.Like that the package will be updated according to the latest requirement.
Now I need to capture the total audit trail history of the package with version wise specific changes and when changes has been occurred hoe can I achieve this?
I am trying to setup logon/logoff auditing for our databases which reside in 9i and 10G on sun solaris servers. I am asked to turn on auditing sending the audit data to syslog! How exactly do you do that?
