How to query the current free memory in the shared pool

Hello

Someone please tell me how to check the current uses of shared pool.

Any query/Tip/document would be appreciated?

If you have found errors ORA-04030 then it is more likely at the PGA instead of the SGA. If you had problems with the shared pool you would probably see shared pool latch wait events and others.

For the ORA-04030 errors, depending on your operating system, can be solved by adding more memory to the operating system or to reduce the amount of work that is performed.

HTH!

How to increase the size of the shared pool?
Hello

How can we increase the size of the shared pool?

can I update "shared_pool_size" parameter in the init.ora file?

Or any other way to change?

Concerning
Rajesh
no need to modify the pfile file, if you use 9i or above versions.

If your database uses pfile then issue
SQL > alter system set shared_pool_size = scope = mΘmoire;

If your database uses spfile then issue
SQL > alter system set shared_pool_size = scope = both; (to reflect changes made to the next start-up also. otherwise scope = memory will be enough)

If your 10g database, you can have SGA_TARGET enabled (by default) in this case it is not necessary to change anything.

If you modify the init.ora file, which will result in the next startup of the database. (means shutdown is required). This isn't average recommeded.

How to load the shared entities

Hello guys! I did experiments with Chargeback manager for awhile, but I have a question. So far, I have seen that with Chargeback manager, it is very easy to calculate the cost of features in a virtual infrastructure (for example, ESXi, VM etc) based on several cost models.
But what happens when we talk about shared resources? For example if a (BU) Business Unit uses an ESXi server, it is very easy to load than BU. You have created a cost report that ESXi and you present to the BU.
But when, on the other hand, you have DRANK using the same things that ESXi (for example a mail server) can become more complicated. You can still find the cost of this ESXI, but how will you allocate this cost on the BU who use this server? For example, divide the cost by the number of BU? Or divide the cost by the number of BU take the consideration of the number of users in each BU... etc...
So the question is, if Chargeback Manager has additional features that could help this process...
Bravo!

Hello

Yes, but the function is only limited to virtual machines directly added to a folder of chargeback hierarchy. Chargeback has an option to share a VM on records (i.e. from Business units). Please refer to the user guide for "sharing cost of Virtual Machine.

For now, you need to calculate the percentage of shares according to the criteria (number of email users) for a virtual computer and use this Chargeback percentage manually.

Kind regards

Why my static PL/SQL within SQL local variable is not transformed in space in the shared pool?

Hello everyone,
Oracle version: 12.1.0.1.0 - 64 bit
OS: Linux Fedora Core 17 X86_64
Description of the problem:
I'm reading an interesting book of online oracle named: SQL in PL/SQL
On page 11, it reads the following:

In the absence of a compilation error, the PL/SQL compiler generates an equivalent statement of SQL regular text and stores this with the generated machine code. This instruction uses placeholders where the embedded SQL statement uses identifiers that have been resolved in the PL/SQL unit.

What I understand of this (please, correct me if I'm wrong) is that whenever I write some static/embedded statement SQL within a PL/SQL block in which there are a few local variables in PL/SQL, and then final generated SQL statement (after resolution of identifier) will include placeholders (bind variables) instead of these identifiers the PL/SQL.
I just wanted to see this in practice, so I made the following test:
Test case:
```
SQL> connect / as sysdba
SQL> alter system flush shared_pool

system altered
```
So, normally, after execution of the foregoing the shared_pool on my development environment is now empty.
And then I run the following PL/SQL block
```
<>
declare
    depid hr.employees.department_id%type := 100;
    cnt   pls_integer := 0;
begin
    select
        count(*)
    into
        b.cnt
    from
        hr.employees t1
    where
        t1.department_id = b.depid;
end;
/
--
--
column sql_id new_value sqlid_saved;
--
select
    v1.sql_id
from
    v$sql v1
where
    v1.sql_text like '%t1.department_id = b.depid%';
--     
-- 
select
    v1.sql_text
from
    v$sql v1
where
    v1.sql_id = '&sqlid_saved';
```
And the result was:
SQL_ID
-------------
687dxvsmrwm9z
g17tjb3f8t94y
6 old: v1.sql_id = "& sqlid_saved"
6 new: v1.sql_id = "g17tjb3f8t94y".
SQL_TEXT
--------------------------------------------------------------------------------
< > declare depid hr.employees.department_id%type: = 100; CNT pls_in
SEB: = 0; Start select count (*) in b.cnt of
T1 hr. Employees where t1.department_id = b.depid; end;

SQL >
What I don't understand is the main part of the SQL_TEXT I put in red.
Instead of
T1.department_id = b.depid
I expected to see something like
T1.department_id = : B
In other words, some bind variable, because depid is a local variable inside my PL/SQL block used in integrated/static SQL statement, so it must be converted to a reserved space in the shared pool instead of the original identifier.
You kindly could you tell me what I misunderstood?
Thanks in advance

> But once again no variable binding in the stored/parsed SQL statement. That's what I don't understand.

Submitted by PL/SQL SQL is "normalized", which includes (among other things) convert uppercase. Your query on v$ sql is looking for '% hr.employees% '.

question related to the shared pool

Hi Experts,
Version of DB - Oracle Database 11g Enterprise Edition Release 11.2.0.1.0
OS - Windows 7
(installed on my laptop)
Just started reading concepts DBA. I had a few questions. Please explain indetail/short ;-).
(1) can we see the size of the Cache of the library and Cache data dictionary which are internal units of the Shared pool.
(2) one of the advantages of the package is - when we invoke a single method, oracle loads the whole package into the buffer and for subsequent calls, it will not go to the db files. Here the buffer means library Cache. My understanding is correct.
(3) I am able to see the two parameters shared_pool_size(value =0), shared_pool_reserved_size (value 15099494) to parameter v$. What is the difference between these two parameters.

Thank you very much in advance for your help.
See you soon,.

The data dictionary cache stores data in database files, tables, etc.

Is there any specific use other than being the container to these 2 Cache the shared pool?

The answer is "it depends." The above are only 2 structures of many other many other structures available in the shared pool. Starting from 10 g, even the undo and redo are kept within the shared pool itself. But most of the structures in the town of pool other than Library Cache and data dictionary Cache requires no intervention on our part is why they are more often discussed in almost every document/place.

How to query the current setting of an element .css?

I have an element on the stage that I'm changing when running.
I need to know the current height of the element to be used in a calculation.
I know how to reset the height, but is it possible, using the script, to determine the current height setting?
TIA,
Carolyn

Any CSS property are accessible as mentioned seano. I would just add sym at the front, since you're on board animate. Just use the correct scope. Then you can use the variable as needed.

var theHeight = sym.$("element1").height ();

How to query the data of Contact with multiple fields

How can I query the data of Contact with multiple fields?
For example, I'll get contacts which are changed after a point at the specified time and whose country is US. How could I make the chain of research of the SOAP API "Query"?
And I also want to know how to make a search term for RESTful API for contacts above.
Any suggestions?
Thank you.

Hi Biao,

The following document describes how query for multiple fields using the SOAP API: request a Contact from several fields.

And you can search multiple fields using the REST API with the & operator. For example, to search for a Contact by e-mail address and date of creation:
- " emailAddress ='[email protected]' & converted > = '1369828886'".
Hope this helps and please let us know if you need more information.

Thank you

Some remarks (apart the obvious syntax error ' to leave'):

-You are missing the namespace declaration in the functions existsNode() and extract()
-You must use extractValue() to extract scalar values
-Given that core_org_id is an attribute, you must use an attribute axis to access (@core_org_id or attribute::core_org_id)

To get started with Ajax - how to query the db without 'submit' page?

Hi guys,.
I'm building a simple "power point presentation" - essentially a CF page that can display a large jpg [slide]) all n seconds, I want the page to query the db to ask whether it is necessary to change the jpg and as appropriate who jpg to see her now. In this way, we can control the presentation by updating the database on the fly.
So I think I will reach it as follows:
1. a 'view' page that contains javascript that fires every n seconds code
2. that js somehow pass 2 variables (GET?) to an action page (ie the user id and authentication var)
3. the action page will be the query to the db (using the variables passed to step 2)
4. the action page returns a result (path to jpg for display) which somehow (?) is passed back to the view page
5. the view swaps page then the jpg is to show for the one passed to him to step 4
6. Ideally the display page then also pass another variable 2 action page let us know it has received the update and changed the image accordingly
I'm fine with all the code html and cfm stuff--where I'm stuck is bit of js, I've had a look through google and do not seem to make any progress so if someone could tell me please in the right direction I would be very grateful.
Excerpts / very welcome advice
TIA
Nick

As well as the very popular jQuery and prototype libraries already mentioned, ColdFusion uses for its wizardary Ajax extJS library and Adobe also provides the Spry library. Or you can roll you own and upwards, use the function xmlHTTPrequest() JavaScript.

But I would like to especially underline that all these libraries using the xmlHTTPrequest() feature and that really, you apply to the server, you use just of to do behind the scenes so that the user does not see this JavaScript. But in regards to the client browser and the server is what are normal requests HTTP and not different responses so if the user clicked on a link or submitting a form.

How to query the object attribute changed his mind in another display object
JDeveloper 10.1.3.4

My requirement is I want to be able to query an object (entity based) view on a nonkey attribute where the value I'm looking on can either be in the database on an existing record or only been experienced by updating a different point of view object based on the same entity (and still commit).

When you query the second display of a value object just updated via a different point of view object, the second view object always returns no rows. I thought that the process is:

EntityA
ViewObjectA based on EntityA
ViewObjectB based on EntityA

ViewObjectA - line query with the key = 123. update the attribute Y with value 456 (attribute Y in the null database). Feature for EntityA cache, touch 123, attribute is updated with the value 456
ViewObjectB - line application with attribute = y. wait record in EntityA just updated cache to be returned. Instead, nothing is returned

Here is the code I was using (where RandScheduleEdit and RandScheduleSearch are the same view the entity RandSchedule object-based objects)
```
  public static void main(String[] args) {
    String        amDef = "test.cache.model.AppModule";
    String        config = "AppModuleLocal";
    ApplicationModule am = Configuration.createRootApplicationModule(amDef,config);
    
    ViewObject rsEdit = am.findViewObject("RandScheduleEdit");
    Key rsKey = new Key(new Object[]{40});
    Row[] rsEditRows = rsEdit.findByKey(rsKey,1);
    Row rsEditRow = rsEditRows[0];    
    rsEditRow.setAttribute("SId", new Number(7827));
    
    ViewObject rsSearch = am.findViewObject("RandScheduleSearch");
    rsSearch.setWhereClause("S_ID = :SId");
    rsSearch.defineNamedWhereClauseParam("SId", null, null);
    rsSearch.setNamedWhereClauseParam("SId",new Number(7827));
    rsSearch.executeQuery();
    Row rsSearchRow = rsSearch.first();
    
    Configuration.releaseRootApplicationModule(am, true);
  }
```
Why not rsSearch finds the S_ID = 7827 record? It seems to only be interviewing new records in the database and ignoring the record updated in cache just updated?

Any help much appreciated.

See you soon,.
