I wanted to know what is the standard memory allocation for SGA & PGA in a normal installation of Oracle database 10g or 11g? Are the figures of 270M and 90M standard for a 10g or 11g installation using automatic memory management feature?
View 9 RepliesI am using 11g version, and trying to understand the Memory Allocation.
1) The new feature Memory target parameters are dynamic? is in it? But when I set with the ALTER SYSTEM... it was not changed, then I had to restart the DB.
2) With the new 2 parameters (MEMORY_MAX_TARGET, MEMORY_TARGET), the SGA_MAX_SIZE parameter should be 0, right? But in my case, the SGA_MAX_SIZE value is automatically assigned.
can I install/use Oracle 10g Enterprise Manager Grid Control if my organization has only Oracle 10g Standard Edition Licences.
View 2 Replies View RelatedI Have a server System Configuration with
RAM size: 16GB Ram & Hard disk Size of 1TB.
I Installed Oracle 11g R2 in the server SystemI want to Allocate Dedicated Memory for oracle..How Should i calculate the Memory size of SGA+PGA for good Performance..
I have the following setup
SQL> show parameter sga;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
lock_sga boolean FALSE
pre_page_sga boolean FALSE
sga_max_size big integer 3G
sga_target big integer 2G
from what I read I beleive this will initially grab 2GB of memory on startup and will grab up to to 3GB of memory total for the SGA. The "total" memory can be allocated to different peices of the SGA when needed but will never exceed 3GB. Is this correct or would these settings infringe on any available memory on a system that is already tight on memory?
Secondly, what happens if both these values are set to the same value?
We are planning the RAC installations. We are allocate 3TB on HP SAN Storage to be used to setup rac environment with 2 nodes.
Question.
1. Do we accept one 3 TB from SAN engineers or ( Which RAID)
2. Multiple Luns totality to 3 TB.
3. Remember this is 11g R1 OCR and VOTING DISK cannot be managed by ASM.
Can i know the internal process of initialization of DB into memory in timesten , when a new connection is establishing? Will timesten create tables and indexes in RAM when first connection is established if the RAM policy is default?

I have the following table
CREATE TABLE "ALLOCATEASSOCIATES"
( "PROJID" VARCHAR2(30) NOT NULL ENABLE,
"ASSOCIATEID" NUMBER(*,0) NOT NULL ENABLE,
"ALLOCATIONSTARTDATE" DATE,
"ALLOCATIONPERCENT" NUMBER(*,0),
[code]...
Given that
1. An associate must be allocated to at-least and a maximum of 100% at any given point of time
2. User selects 2 dates between which inconsistency of allocation needs to be displayed
If the end user selects 1st Apr 2012 and July 31st 2012 between which reports needs to be generated, am looking for the following output
ASSOCIATE_ID FROM_DATE TO_DATE ALLOCATION_INCONSISTENCY
2 01-APR-12 15-APR-12 75
2 16-APR-12 15-JUN-12 25
2 16-JUN-12 30-JUN-12 50
The Allocation_Inconsistency denotes that the associate has a deficit of allocation between the 2 dates. The associate with ID 2 has a deficit of 75% of allocation from 1st Apr 2012 till 15th Apr 2012. Similarly 25% deficit between 16th Apr 2012 and 15th June 2012 and so on so forth. However, there is no allocation deficit for the month of July as he is allocated 100% for this month and hence is not appearing in the expected output.
Phyical memory : 420G My database version : 11.2.0.3 running on linux machine.
Memory_target = 200G . I would like to allocate this value to following SGA components. I don't want to automatic memory management enabled. how to split 200G for following components. Is there any percentage for each components ?

I want the output from two tables with rows to columns and generate dynamic basing on the columns.
For example: Table A (a1) , Table B(a1,b1)

1 1 x
2 1 y
3 2 a
2 b
2 c
o/p: Columnname col_1 col_2 col_3

a1 b1_1 b1_2 b1_3
----- ---------------------
1 x y
2 a b c
Columns should be generated based on the second table second column.
I want to change space allocation for character columns in my database, So it will store them as 'CHAR' and not 'BYTE'.my character set is
SQL> SELECT VALUE FROM V$NLS_PARAMETERS WHERE PARAMETER='NLS_CHARACTERSET';
VALUE
----------------------------------------------------------------
AL32UTF8
SQL> alter system set NLS_LENGTH_SEMANTICS='CHAR' scope=both;
System altered.I bounced the instance just to make sure
System altered.
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
Connected to an idle instance.
SQL>
SQL>
SQL> startup
ORACLE instance started.
[code].....
And then I want to see that when I create a table with some varchar2 column,The space for it will be allocated by chars, and not by bytes! However, when I run a check of create table, this is what I get:
SQL> drop table check_char;
Table dropped.
SQL> create table check_char (some_name varchar2(10));
Table created.
SQL> select a.char_used
2 from all_tab_columns a
3 where table_name='CHECK_CHAR'
4 and a.owner='SYS';

What is the reason for space allocation to remain in BYTES and not CHAR, or what else I can check?

Here i understand that RMAN couldn't find which SPFILE to use to restore the target DB.
How do i check for the DB_UNIQUE_NAME in recovery catalog?
The proposed solution that i found was Use the FOR DB_UNIQUE_NAME option to specify the name of the instance whose parameter file you want to restore. how to implement this in my clone script?

View 2 Replies View RelatedI am checking out licenses. We all know that EE is much more expensive than SE. But many customers do have EE installed - unsure if they need all the features at all. After several years of production, a downgrade is considered 'risky' and we continue to pay the full EE.
How can we check and be sure that a downgrade to SE would not be any problem?
Some checks include:
* partitioning used in user schemas? --> no downgrade to EE
* bitmap indexes in user schemas? --> no downgrade to EE
How can we complete this list, or is there some script to make this easy?

Use ANSI standard JOIN syntax for example i have this code.
SELECT resv_num, unit_date
FROM p_resv_unit ru, p_pm_unit_night pun
WHERE pun.property_id = in_property_id
AND pun.pm_unit_num = cvUnitNum
AND pun.unit_date BETWEEN start_date AND end_date
AND pun.resv_unit_id = ru.resv_unit_id;

and is it a good idea to change it, because both ways it works?
