To tune the OID11g the DB parameter recommendation is :
sga_target Minimum 60% of RAM
sga_max_size Minimum 60% of RAM
db_cache_size Minimum 60% of RAM
So what is RAM size..is that the RAM size on the linux BOX which is 8 GB in my case
or RAM size assigned to Oracle DB?
If I take RAM size 8 GB I am not able to modify the parameter. I am getting below error:
SQL> alter system set sga_max_size=4916M scope=both;
alter system set sga_max_size=4916M scope=both
*
ERROR at line 1:
ORA-02095: specified initialization parameter cannot be modified
how to check that total memory assigned to Oracle DB?
7 rows selected.However, the SGA_MAX_SIZE parameter is set to 3G, so when I do:
SQL> ALTER SYSTEM SET sga_target=5376M scope=both; ALTER SYSTEM SET sga_target=5376M scope=both * ERROR at line 1: ORA-02097: parameter cannot be modified because specified value is invalid ORA-00823: Specified value of sga_target greater than sga_max_size
My database used spfile. I know that the procedure to change this is the following: Create pfile from spfile, shutdown immediate, change value in pfile, startup with pfile..However, the pfile does not have any parameter called max_sga_size. It only has the following:
I've done lots of reading about these two parameters, SGA_MAX_SIZE and DB_CACHE_SIZE.
What I understand now is, that setting db_cache_size to a target value and setting all other buffer cache setting to 0 will enable Oracle 9i to automatically manage buffer cache values, right? This is, per meta link document 223299.1 the most important parameter in Oracle 9i regarding memory management.
Now, SGA_MAX_SIZE set the maximum value at wich I can increase the db_cache_size to?
The question is ; WHY? Why should I allocate 1G of RAM to my oracle instance and not set the db_cache_size to the exact same value? What happens with the difference in memory between the SGA_MAX_SIZE and the DB_CACHE_SIZE, ex :
SGA_MAX_SIZE = 1000M DB_CACHE_SIZE = 500M
What happens with the 500M left over, is it used for anything ?
So I bounce my instances and when I checked the parameter SGA_MAX_SIZE, Oracle automatically set a value of 2456M to it:
sga_max_size big integer 2456M sga_target big integer 0
Reading MOS ID 443746.1, there is no clear mention about this relationship. It seems that Oracle automatically set SGA_MAX_SIZE as 60% of MEMORY_TARGET.
In am running Oracle 11gR2 (11.2.0.2.3) under Red Hat Linux.
let's say a parameter changed in the database ex: alter system set retention_target= 1500; and i want to know what was the old value before it has been changed ,
From ETL tool i will be passing two parameters to a procedure. I want to know whether this parameter can be used in a select statement of a correlated query.
Query to be in the procedure :
begin update table1 set table1.col1 = (select parameter2 from table2 where table2.x = table1.x and table2.x = parameter1) ; commit; end;
parameter2 will be having the columnname to be passed. And everytime different columnname will be passed to this procedure.
I am writing a procedure in which I have a input string parameter in the following way..('NYC,ATL,OKC,KAC,LA'). I need to use that string to search values in the table.
Example
create or replace procedure search_city(p_string varchar2) /* paramater will be like ('NYC,ATL,OKC,KAC,LA') */ is v_city varchar2(40) begin for i in (select city_name from cities where city_code in (p_string ) ) loop
CREATE OR REPLACE PACKAGE test_package IS TYPE refcur IS REF CURSOR; END test_package; CREATE OR REPLACE PROCEDURE get_info(o_cursor OUT test_package.refcur) AS BEGIN OPEN o_cursor FOR SELECT * FROM emp; END get_info;
What is the advantage of using refcursor variable as OUT parameter in procedure. Instead of that why cannot we use variables or TYPE variables. use ref cursor as OUT parameter in procedure.
I need to test a parameter in a script that must adhere to what is currently in the database.For example, when a user enters the value when prompted from this script, ("Enter the schema copy desired: " ) the value must be of the current values in the db:, it would be something like this:
Values currently in DB: copyofschema201110 (the 2011 is the year, and 10 would be the month of oct).
copyofschema201109 copyofschema201108
So, if the user enters the value 'abc' (an incorrect value), then I would like the script to stop the user, and kick back a message, say from dbms_output.put_line, and force the user not to go forward, but re-enter a correct value.
I thought that you are not supposed to be able to assign the value of an out parameter to a variable (Feuerstein, 5th ed) and yet I was just able to do this without any compilation error messages. Is Feuerstein wrong or am I missing something? Has the functionality changed?

I have a scenario where I have to pass a paramter to "in statement". When I run the query from SQL plus its working fine.......but when I run the query at run time it doesnot come back with the results. I am sure its formating issue.
This is how I create a paramter

We are seeing volume issue when taking Rman level 0 backup for a database , the database version is 11.2.0.2 and its on RHEL 2.1. As 11g supports compression for RMAN, we have implemented so as to reduce the backup space used.
" CONFIGURE COMPRESSION ALGORITHM 'LOW' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE "
However during full backup the volume size increases, meaning we have to increase /data volume (currently 500G) to more then a 1T for just rman to go through, else the backup hangs. Once backup is done we again bring down the volume size to less then 1T. The other compression parameters are HIGH and MEDIUM, hoever I am not very sure if changing to high or low will work as I couldn't find any right doc in meta link or may be I didn't searched correctly, I will continue to look for that.

I have this in one of the packages WCL_LIB: TYPE vc2_255_arr IS TABLE OF VARCHAR2(4000) INDEX BY BINARY_INTEGER;
and i use it in one of the procedures as PROCEDURE "WCL_EVENTS" (p_event_id IN NUMBER, p_event_arr IN Wcl_Lib.vc2_255_arr, p_model IN VARCHAR2 DEFAULT NULL, p_model_code IN VARCHAR2 DEFAULT NULL
but the calling procedure doesnt have any array.... Can I declare something like in the procedure to be called p_event_arr IN Wcl_Lib.vc2_255_arr DEFAULT NULL,
I tried, but doesnt seem to work? so how to call the procedure, which has a array as mandatory, but calling one doesnt have any?
I have the procedure with out parameter is ref cursor.
l_sql VARCHAR2(32767); BEGIN l_sql := 'select query with appending procedure IN aparameters'; OPEN rc_rpt FOR l_sql;
Here procedure IN parameter is a string with comma separated value which is appended in the dynamic query IN clause.So some time the size exceeded more then 32767 and getting error.If i am using normal parametrized cursor this issue is not there,but i want to return only ref cursor for some java purpose.My oracle version is 10g.
how to use different where caluse based on different in parameter. say I pass 1,2 as parameter if it is 1 then the where condition > 10 else if it is 2 then the where condition <5 the where conditions are placed in cursor for loops.

how to use collection variables as OUT parameters in procedure.
i am trying to create a procedure that will take an input and based on that input it will delete or update a row, if the input is wrong we will dbs_ouput a line telling the user to enter the input again. can i have a input parameter in a procedure and insert multiple rows with a single insert on a procedure?
I have a procedure with 20 parameters, acutely it is to update a table and each param represents respective columns in a table. I want to update only few selected columns(random), as of now am passing Null as param values for remaining.
Is there any way to ignore the unnecessary parameters instead of passing NULL value.My Proc call looks like...
we have a table which name is empl have two column (comapnyname,jobdate) i want output after passing parameter which name is month which value is like(feb 2011,or mar 2011 or apr 2011 or jun 2011 etc) output should come the nameof company with jobdate whose jobdate is equal to 3 or greate than three
name of company,jobdate whose job date in particular month is greater than three or equal to three the purpose of this we want to find only the name of company where we visit morethan three times in particular month table structure is
insert into empl values('ABC','1-feb-2011') insert into empl values('ABC','10-feb-2011') insert into empl values('ABC','21-feb-2011') insert into empl values('xyz','18-feb-2011') insert into empl values('xyz','1-feb-2012') insert into empl values('xyz','1-apr-2011') insert into empl values('ABC','28-feb-2012')
