Server Administration :: Settings Infringe On Any Available Memory On System That Is Already Tight On Memory?

Jul 25, 2012

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?

Server Administration :: Block Corruption - Segment Not Found

I have a database where view v$database_block_corruption shows a corrupted block

SQL> select * from v$database_block_corruption;

FILE# BLOCK# BLOCKS CORRUPTION_CHANGE# CORRUPTIO
---------- ---------- ---------- ------------------ ---------

I am not able to get the relevant segment from the above information

SQL> select segment_name, segment_type, owner

4 and 756652 between block_id

I have uploaded the complete logfile.

Below is a part of logfile

here i tried finding the OBJECT ID as below

Now for the same BLOCK it is giving different File, again the segment_name or segment_id could not be found from the above information.

Server Administration :: SGA Memory Filled

Apr 14, 2012

We are running oracle9i database in windows 2000 server few months before i re sized the SGA to sga_max_size =800M and pga-aggregate_target to 400M, actually we have 4gb RAM out of the we are allocated 1200Mb for SGA and PGA.

My question is if the allocated memory got filled in SGA or PGA whether the system will show any error, because when I am querying from sql> show parameter ; the sga free memory is reducing daily what will happen when it reaches its max_size.

Server Administration :: How Does SGA And PGA Split Memory When We Use MEMORY_TARGET

Mar 28, 2010

I read in few blog and they are saying, oracle11g allocate 60% of the memory to SGA and 40% of the memory to PGA when we enable MEMORY_ TARGET to non-zero.Here are few blogs. URL.....It is not working on that way(60:40) on my database.

Here is my DB version.

Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
PL/SQL Release 11.1.0.7.0 - Production
CORE 11.1.0.7.0 Production
TNS for Linux: Version 11.1.0.7.0 - Production
NLSRTL Version 11.1.0.7.0 - Production
[code]....

I am not able to find 60%:40% concept in oracle document..so all the above blogs info are wrong?

Server Administration :: Automatic Memory Management

Apr 7, 2013

I have read this article:

[URL].........

And i see:

Quote:
If MEMORY_TARGET is set to non zero value:
SGA_TARGET, SGA_MAX_SIZE and PGA_AGGREGATE_TARGET are set to 0, 60% of memory mentioned in MEMORY_TARGET is allocated to SGA and rest 40% is kept for PGA.

So, I have set:
alter system set sga_target=0 scope=spfile;
alter system set pga_aggregate_target=0 scope=spfile;
alter system set sga_max_size=0 scope=spfile;
alter system set memory_max_target=512M scope=spfile;
alter system set memory_target=300M scope=spfile;

, and then bounced the instance.
After startup, I see:

SQL> startup
ORACLE instance started.

Total System Global Area 272027648 bytes
Fixed Size 1384012 bytes
Variable Size 100663732 bytes
Database Buffers 163577856 bytes
Redo Buffers 6402048 bytes
Database mounted.
Database opened.
SQL>

But Total System Global Area should't be in that case 60% of memory mentioned in MEMORY_TARGET? Memory mentioned in MEMORY_TARGET was 300M, and 60% of 300M is 180M, which is not 272027648 bytes.

I just want to use automatic memory management, so I've set the other parameters above to 0. My instance is on my local machine, so just for my own personal use.

Server Administration :: Unable To Use More Than 2GB Memory For Oracle In Windows 2003

Jun 17, 2011

I have a 11g database installed on a windows 2003 server. When I created the database I could not assign more than 2GB for SGA_TARGET where as I have 16GB of RAM available on the server. I created the database with SGA_TARGET as 1.5 GB and Memory_TARGET as 2GB. I could create the database successfully. Later when I again tried to increase SGA_TARGET to 6GB and MEMORY_TARGET to 8GB, I could not start the database. I got below error;

ORA-27102: out of memory

OSD-00022: additional error information

O/S-Error: (OS 8) Not enough storage is available to process this command

Quote:I added /pae in the boot.ini
Added AWE_WINDOW_SIZE key to registry as 2000000000
Set use_indirect_data_buffers=true
added db_block_buffer=131072 (ie. 2GB DB_BLOCK_SIZE=16kb)
java_pool_size= 1000M
large_pool_size=1000M
shared_pool_size=2000M

I got again the same error

I could not use SGA_TARGET. So is AMM not allowed with AWE?

i try to startup a database, and get that obsolete/deprecated parameter specified(ORA-32004: obsolete and/or deprecated parameter(s) specified)so i try to reset the parameter, but it seems it is already reset(not in spfile), so maybe this is in memory. SO now i try to reset with scope = memory or both, it gives this error(ORA-32029: resetting with SCOPE=MEMORY or SCOPE=BOTH is currently not supported).

what to do, because now i cannot reset with scope = memory and in spfile it is not there but still it comes in deprecated parameter.

Server Administration :: Unable To Allocate 4120 Bytes Of Shared Memory

Jan 1, 2013

I have a package when it runs, it terminates with "unable to allocate 4120 bytes of shared memory"error at a particular INSERT statement. So everytime we had this error, we had to flush the shared pool area, after which it would run without issues(for 3-4 weeks).

It had a dynamic subpartition clause framed, which made it to repharse the query every time.So to reduce this, we removed the subpartition clause(made it to static query), which did benefit of not getting shared pool error.

I would like to find the current shared pool memory usage of my program.Is there a way I could find the live consumption of shared pool area of my program(pkg).

PL/SQL :: Updating 2 Tables Side By Side

Apr 4, 2013

sqlplus experts,

How do I update Table2(idno) with values of Table1(idno)? By the way there are other columns which i do not want to be touched. This is just to create a match parent-child table test data.

Example:

Table1

idno
===
100
101
102
103

Table2

idno
===
any no
any no
any no
any no

I want all idno values in Table2 to be identical with Table1. It can be any order as long as the value is 1 to 1. I just want it populated for test data purposes.
