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.
ENV: Oracle 10g R2 EE on ADM, RHEL 5.8 64bit
Is there a difference performance wise if ASM gets two LUNs of 1.7TB (DATA) and 0.6TB (FRA) respectively compared to 17 LUNs of 100GB each (for DATA) and 6 LUNs of 100GB each (for FRA)? Is there a recommended size from Oracle?
I 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..
difference between stripe attribute and the AU size.The ASM distributes the data in AU in the disk, and what the role of strip size in this case?
View 2 Replies View RelatedI 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.

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 ?
db_cache_size
db_recycle_cache_size
db_keep_cache_size
large_pool_size
java_pool_size
shared_pool_size
pga_aggregate_target
streams_pool_size
log_buffer
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?

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';
C
-
B
SQL>
What is the reason for space allocation to remain in BYTES and not CHAR, or what else I can check?
while executing a clone script i got the below error : -

RMAN-06758: DB_UNIQUE_NAME is not unique in the recovery catalog
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?
I am getting problem while starting the CRS. Below is the necessary details:
1) I am using oracle 11g R2 RAC, with 2 node named RAC1 and RAC2
2) I have 3 diskgroup named DATA, DATA1, DATA2
3) OCR and voting disks are stored on ASM diskgroup
On node RAC1, CRS is started and /etc/oracle/ocr.loc is having the below entry:
ocrconfig_loc=+DATA
ocrmirrorconfig_loc=+DATA1
On node RAC2, CRS is stopped and /etc/oracle/ocr.loc is having the below entry:
ocrconfig_loc=+DATA
ocrmirrorconfig_loc=+DATA2
note the difference in "ocrmirrorconfig_loc". The difference was occured because I updated the OCR location on RAC1 when RAC2 was down.
Now I am trying to repair the RAC2 using below command. This command must be run as root user when HA service is started but CRS must be stopped.
ocrconfig -repair -replace +DAT2 -replacement +DATA1
but this showing error "PROT-21: Invalid parameter", because to run this command diskgroup must be mounted. But diskgroup cannot be mounted until the CRS start. SO this is a conflicting situation.
We have to perform migration for our RAC database to new SAN that is at new data centre. Since OS is IBM AIX, we can take backup from mksysb for VG and and storage will migrate data from OLD SAN to NEW SAN.
But even we restore VG and SAN data but since our old SAN is emc and new SAN is hitachi, so disk path for all the asm disk group will be changed.
So is there will be any way to rename this disk path for disk group..
We have an Implementation of Non-RAC (Single Instance with Existing ASM-RAC as storage) and below is the Details,
The client have a Real Application Cluster configuration on their AIX Server from there Data Center and they want to implement a Single instance Database that will used ASM as Storage and the storage or Disk that they want to use is the same Disk or Mirror copy of the Disk from their RAC Database.
Scenario:
-The AIX Server that they have is a one-way Hardware Mirroring (PPRC) only and it is not designed to run a 24/7 activity.
-DATAGUARD is not an option.
I have 2 node 11gR1 running on Unix, I want to add 3 more RAC node to it. What are all the steps involved and should I first add 3rd node and then the 4th node or I should add both at the same time? is there any difference between these two methods?
