Memory used by oracle 11g processes on solaris 10

I am running oracle 11.1.0.7 on solaris 10. The database uses some 280M virtual memory size for each oracle backup or user process. See the SZ column in output of ps -efl below.
I just wonder how come oracle that much of memory for each process. Is that something we can control through some system/database parameters or is that the way oracle 11g on solaris works?

Is that something we can control through some system/database parameters or is that the way oracle 11g on solaris works?As you have already said, it is "virtual" memory. This is not real, "physical" memory. Solaris has a virtual memory sub-system layer in it, as do almost all other modern operating systems. Google "operating system virtual memory" to find out more on what virtual memory is and how it works.
In terms of your question, virtual memory means that not all of a process's memory space needs to be in physical memory for it to run and execute. The process virtual memory space is broken up into equal sized pages, and only those pages currently being referenced (used) are mapped and read into physical memory pages. Thus the virtual size of a process is irrelevant to how much physical memory is being used. Look at the RSS column (ps -ely) for the physical memory used by each process - Resident Set Size.
Furthermore, an Oracle shadow server process (oracle) uses a large segment of shared memory for the SGA. This shared memory only exists once in physical memory, and is shared amongst all the shadow server processes. But it is mapped into the address space of each process, and so appears and is counted in the virtual and physical memory of each process.
So each reported virtual size (SZ) of each oracle process is also counting the mapped shared memory pages in each process, and so counting the same pages multiple times across all the oracle processes. You need to subtract the size of the SGA shared memory from the virtual size of each oracle process to determine the private, local memory per shadow process.
If you want a further breakdown of the memory map of each process, look at the manual pages for pmap (man pmap), which will break it down by text, private data, zero initialized, shared and other types. By subtracting the shared size from the resident size you can get a true view of the private, local memory per oracle shadow server process.

The danger of memory target in Oracle 11g - request for discussion.

Hello, everyone.
This is not a question, but kind of request for discussion.
I believe that many of you heard something about automatic memory management in Oracle 11g.
The concept is that Oracle manages the target size of SGA and PGA. Yes, believe it or not, all we have to do is just to tell Oracle how much memory it can use.
But I have a big concern on this. The optimizer takes the PGA size into consideration when calculating the cost of sort-related operations.
So what would happen when Oracle dynamically changes the target size of PGA? Following is a simple demonstration of my concern.

1. Oracle invalidates the query when internal pga aggregate size changes, which is quite natural.
2. With changed pga aggregate size, Oracle recalculates the cost. These are excerpts from the both of the 10053 trace files.

Bug Fix Control Environment10053 trace file clearly says that Oracle recalculates the cost of the query with the change of internal pga aggregate target size. So, there is a great danger of unexpected plan change while Oracle dynamically controls the memory segments.
I believe that this is a desinged behavior, but the negative side effect is not negligible.
I just like to hear your opinions on this behavior.
Do you think that this is acceptable? Or is this another great feature that nobody wants to use like automatic tuning advisor?

(I'm still in dark age on this automatic memory target management of 11g. More research in need!)
I think that this is very clear and natural behavior. I just want to point out that this would result in unwanted catastrophe under special cases, especially with some logic holes and bugs.

Monitoring memory used by Oracle instance

Hi,
How can i check how much memory is being used and allocated by an Oracle instace? Is there any way to do?
Ashish

An Oracle instance is using SGA that is shared memory by all background processes and dedicated/shared server processes and PGA which is private memory used by each server process.
For SGA you can use following queries:
select * from v$sgastat
In 10G, you can also use:
select * from v$sgainfo;
For PGA, you can use following query:
select * from v$pgastat;

Install Oracle 11g RAC on Solaris 10

Hello,
I'm new joined DBA in my organization.
There is a requirement from a client to install Oracle 11g RAC on Solaris 10 env.
Can anybody please guide me with some doc or pdf for the steps.
Till now, i've install Oracle 11g DB on Solaris, but i'm pretty new to RAC env.
Note:
I've to do installation via commands, No GUI.
Thanks for your help.
Regards,
Gags

Hi,
Q) Can Oracle 11g Release 2 RAC be installed on Solaris (x86)??yes, you can Install it on Solaris X86
Q) Can the links of Oracle RAC installation over Unix and Linux be taken as base?? As i haven't seen any doc for installing 11g RAC on Solaris, where as it was provided in Oracle 10g.yes, you need to consider Oracle RAC installation over Unix and Linux be taken as base as base document.

Thank you in advance..In general, each product has an installation manual - found through http://docs.oracle.com and possibly http://tahiti.oracle.com and the install manual clearly identifies the (minimum) support OS and Release information.

Factors for increase in memory occupied by Oracle 11g database

I wanted to know all the possible factors which can account for the increase in the memory required for an Oracle 11g database. Let’s take an example,
1) Say if the memory allocated for an Oracle 11g instance is 8GB which is 50% of the memory of 16GB allocated to the machine on which Oracle 11g is installed.
2) The max sessions are 300.
With this example in mind, I had the following queries:
1) Is the memory taken by 100 sessions or 300 sessions going to be within the limit of 8GB allocated to the Oracle?
2) Say if the max sessions is increased to 400, would the memory taken the 100 extra sessions would be within 8GB or would that be extra?
I hope my query is clear.
Please revert with the reply to my query.
Regards

Memory is allocated for the session only when that session is created by the listener, and the memory used by that session will fluctuate depending on the workload it's doing.
300 or 400 it won't pre-allocate all the memory for the fixed maximum number of sessions, it's dynamic. What oracle does is allocated all the memory you gave it in the PGA and the SGA and will do it's best to work with it for the current workload, it won't suddenly eat more memory without you telling it's okay to.
The only scenario I could see this happening is if you have a lot of sessions and a small PGA. In that case, oracle does go ahead and eat more memory than you gave it because it can't make due with the current PGA. So it eats more memory so sessions can be created and maintened. See PGA over- allocation.
To quote the good ol' docs:
Over allocating PGA memory can happen if the value ofPGA_AGGREGATE_TARGET is too small. When this happens, the Oracle Database cannot honor the value ofPGA_AGGREGATE_TARGET and extra PGA memory needs to be allocated.

Index not being used in Oracle 11g

Hi,
I executed an SQL in Oracle 9i based on a Materialized View with an index. Execution plan shows it used Index and did Range scan. But the same query if I executed in Oracle 11g, it did full table scan and ignored the index. Finally, I used /*+Index*/ hint to tell compiler to use the index. Can anyone tell why it happended like this.
below is the query.
SELECT TYPE,NAME,PARENT_ID,CHILD_ID,UNIT_OF_MEASURE,QUANTITY,POSITION_NUMBER

My doubt is only that is it possible that a SQL query with same index proprties uses different access path to execute. Is it dependent on oracle version also.
Yes, it is possible.
It is even possible on the same Oracle version - look at simple examples:
case 1
create table test as
select level l, 'test' test from dual
connect by level < 1000;
create index test_ix on test(l);
explain plan for

drop table test;
create table test as
select * from (

) order by dbms_random.value(0,100);
create index test_ix on test(l);
explain plan for
select * from test where l < 50;
select * from table(dbms_xplan.display);

Note
   - dynamic sampling used for this statement (level=2)The same query on the same table containing the same data in it. And the same index.
The only difference is records order in the table.
In the first case CBO decided that index range scan would be reasonable.
In the second case CBO preferred FTS as less costly.

Oracle 11g Installation on SOlaris 5.10

Hi ,
First i am going to install oracle 11g on solaris 5.10 . Could some one tell me what are the requirements required if not please send me the better link which i can follow for my installation ...

Memory target with Oracle 11g

Hello All,
I am using Oracle 11gR2 on AIX 7.1.
My question is about memory_target parameter with RAC, what I usually do is to put this parameter equal to 40% of the RAMs on the database server in single instance database.
With Oracle RAC, should it be 40% of the summation of RAM on all nodes? for ex if I have 2 nodes with 40 GB RAM on each node, so i can put my memory_target= 40% of (40+40)= 32 G ?? is that correct or it will be 40 % of the RAM on 1 node?? is it by Instance or by database ?
How do i know if a parameter is at the database level or instance level?
Regards,

Regards,Its _40 % of the RAM on 1 node_ recommended approach. Since Memory_target wil consume the memory of server, so rest 60% is available to OS to do his work. If you put 40% of (40+40) = 32 GB on each node then there is very little memory left for OS(you can see decrease in performance).
Its 2 node RAC, so each instance has its own set of parameter in pfile/spfile. So we can say its instance specific. Each node can have same of different values of memory_target parameter

Which tool is used for Oracle 11g performance tuning?

Hi all
I used statspack for 9i's performance tuning.
But with 11g R2 now I want to know which way are you using to do performance tuning?
Statspack? OSW? RDA? ADDM? Or other ways?
Thank you.

SriniThanks for your answer.
To read the MOS documents I need a Oracle Customer ID , is that right ?
(Where to get that ID ? Our company bought Oracle 10g without any Customer IDs in it )

Oracle 11g client installation on Solaris in non GUI mode

Hi,
I want to know if there is a way i can install Oracle 11g client on Solaris 10 machine in non GUI mode (ie. i want to do it from a command based terminal)
Thanks
Anup

Hi Anup
You have two ways to install it
1) Client installation without response file
Please Refer to Doc ID 885643.1
2) With Response file
Refer to the document available in Document library
Document Oracle® Database Client Installation Guide
11g Release 2 (11.2) for Solaris Operating System
Note: from 11gR2 onwards you can create a response file from GUI also and then use it later on for silent installation.
Hope this is helpful for You

Can I use oracle client 10g express to work on oracle 11g database

I have installed an oracle DB 11g, I also installed oracle client 10g express edition to create users and tables. I noticed that the users I created can't connect to db with error message "Error java.sql.SQLException: ORA-01017: invalid username/password; logon denied" and tables I created can't access from my program. I get error message "Error java.sql.SQLException: ORA-00942: table or view does not exist". I start to suspect that client 10g express edition can't use with oracle 11g. Please help.
any suggestion is appreciated.
Thanks,

ORACLE 10g PERFORMANCE ON SOLARIS 10

Hi all,
In sunfire v890 we have installed oracle 10g release 2 on solaris 10.
prstat -a command shows :

therefore from prstat we come to know that memory used by oracle is 71%
where as top says 31.25% used.....
which one is true in this scenario.....
shall we go ahead in trusting top utility????
Advance thanks to you.

used by oracle is 71%

But lots of the memory used by Oracle is shared between several processes. prstat is counting that shared memory over and over for each process... resulting in the higher figure.
