PARALLEL_MAX_SERVERS, how it can impact my database

Hello, I´m trying to do a select with 200 parallels, using the parallel hint to do it. But my PARALLEL_MAX_SERVERS by default is 96, I can change this number , but I would like to know how this change can impact my database. I read in the Oracle Guide, that "If you set it too high, memory resource shortages may occur during peak periods, which can degrade performance.", but i want to know if it´s only the PGA or there´s another place.
The database is the 10g R2.
Thanks,

The database is the 10g R2.Simply setting the parameter to a higher value doesn't impact your database. I guess the comment is more targeted towards the excessive usage of parallel slaves which is possible if you use a high degree of parallelism and/or simultaneous execution of multiple parallel operations (if PARALLEL_ADAPTIVE_MULTI_USER setting is not active) and PARALLEL_MAX_SERVERS / PROCESSES allow such a high number of processes.
You may allow the question how do you come to the conclusion to run a statement with a parallel degree of 200 if your default value of PARALLEL_MAX_SERVERS is 96 which suggests that you don't have that many CPUs in your system (at least which are visible to Oracle, check CPU_COUNT parameter).

Changes made in BCC how it be impact in the code & Database

Hi,
Whatever changes made in BCC how it be impact in the code & Database . Example : Price ll be change in the BCC . Could u please briefly explain about this.

Hi Gugan,
From your description if i am understanding correctly, i think you are looking for information on BCC VS production like the changes which are performed in BCC how they are reflecting in DB and then production, if this is your question.
BCC will have its own Database which is version and maintain the information of production Database and agents which are our production sites.
When you observe CA console you will come to know about agents, along with that there will be a repository mapping which will map source repository to destination repository which will make sure that the data is mapped to correct repositories.
after configuring all required sites and repository mappings when we do a deployment with changes, a successful deployment will push the data to the production data base and a cache invalidation will take place so that the newly deployed changes will appear on the production site.
you can find a very nice explanation on ATG Content Administration Programming Guide
if you are looking on some thing else feel free to update the post.
Thanks & Regards

How I can transfer data from the database into a variable (or array)?

I made my application according to the example (http://corlan.org/2009/06/12/working-in-flash-builder-4-with-flex-and-php/). Everything works fine. I changed one function to query the database - add the two parameters and get the value of the table in String format. A test operation shows that all is ok. If I want to display this value in the text area, I simply drag and drop service to this element in the design mode
(<s:TextArea x="153" y="435" id="nameText" text="{getDataMeanResult.lastResult[0].name}" width="296" height="89" />).
It also works fine, just a warning and encouraged to use ArrayCollection.getItemAt().
Now I want to send the value to a variable or array, but in both cases I get an error: TypeError: Error #1010: A term is undefined and has no properties..
How can I pass a value from the database into a variable? Thank you.
public var nameTemp:String;
getDataMeanResult.token = authors.getDataMean(arrayOfNumber[0], dir_id);
nameTemp = getDataMeanResult.lastResult[0].name;
public var nameArray:Array = new Array();
for (var i:uint=o; i<3; i++){
getDataMeanResult.token = authors.getDataMean(arrayOfNumber[i], dir_id);
nameArray[i] = getDataMeanResult.lastResult[0].name;
And how i can use syntax highlighting in this forum?

I have to go back to the discussion. The above example works fine when i want to get a single value of the database. But i need to pass an array and get an array, because i want to get at once all the values for all pictures tooltips. I rewrote the proposed Matt PHP-script and it works. However, i can not display the resulting array.
yep, it won't work for Arrays, you'll have to do something slightly more intelligent for them.
easiest way would be to get your PHP to generate XML, then read that into something like an ArrayList on your HTTPService result event (depends what you're doing with it).
for example, you could have the PHP generate XML such as:
<pictures>
     <location>test1.png</location>
     <location>test2.png</location>
     <location>test3.png</location>
     <location>test4.png</location>
     <location>test5.png</location>
     <location>test6.png</location>
</pictures>
then you'll read that in as the ResultEvent, and perform something like this on it
private var tempAC:ArrayList = new ArrayList
protected function getStuff_resultHandler(event:ResultEvent):void
    for each(var item:Object in event.result.pictures)
       var temp:String = (item.@location).toString();
       tempAC.addItem(temp);
in my example on cookies
http://www.mattlefevre.com/viewExample.php?tut=flash4PHP&proj=Using%20Cookies
you'll see an example of how to format an XML structure containing multiple values:
if($_COOKIE["firstName"])
        print "<stored>true</stored>";
        print "<userInfo>
                <firstName>".$_COOKIE["firstName"]."</firstName>
                <lastName>".$_COOKIE["lastName"]."</lastName>
                <userAge>".$_COOKIE["userAge"]."</userAge>
                <gender>".$_COOKIE["gender"]."</gender>
               </userInfo>";
    else
        print "<stored>false</stored>";
which i handle like so
if(event.result.stored == true)
                    entryPanel.title = "Welcome back " + event.result.userInfo.firstName + " " + event.result.userInfo.lastName;
                    firstName.text = event.result.userInfo.firstName;
                    lastName.text = event.result.userInfo.lastName;
                    userAge.value = event.result.userInfo.userAge;
                    userGender.selectedIndex = event.result.userInfo.gender;
depends on what type of Array you're after
from the sounds of it (with the mention of picture tooltips) you're trying to create a gallery with an image, and a tooltip.
so i'd probably adopt something like
<picture>
     <location>example1.png</location>
     <tooltip>tooltip for picture #1</tooltip>
</picture>
<picture>
     <location>example2.png</location>
     <tooltip>tooltip for picture #2</tooltip>
</picture>
<picture>
     <location>example3.png</location>
     <tooltip>tooltip for picture #3</tooltip>
</picture>
etc...
or
<picture location="example1.png" tooltip="tooltip for picture #1"/>
<picture location="example2.png" tooltip="tooltip for picture #2"/>
<picture location="example3.png" tooltip="tooltip for picture #3"/>
etc...

How I can save the value of a variable in a database?

hello,
how I can save the value of a variable in a database? I need to keep the # of times you press click animation. to know how many times it has been seen.
I connect to msql database, using php, javascript, ajax and jquery, but not how to save the variable counter clicks from adobe edge Animate
appreciate your help so I can connect to the database from adobe edge animate.
thank you very much
Luis Felipe Garcia

Hi, all-
This isn't an Animate-specific issue, but I thought I'd take a stab at it anyway. As with anything else on the web, you need to have a server script to handle incoming data, so it's all back end work. Your page will need to call that script and provide parameters to that script that it can read.
The easiest way I can think of to do this (and this is all highly theoretical, so please make sure it's secure before you implement it) is to create a 1px div that has visibility off. Whenever you click, you can load your URL in that div, which then increments your counter on your db.
Hope that helps inspire some interesting solutions!

How can we handle database exceptions in bpel?

Hi,
I'm calling a couple of pl/sql based services in my bpel flow. Given the services are pl/sql based we might hit some databse errors . For example:
-Existing State of Packages has been discarded
-Database is down
-PL/sql procedure itself throws an error etc
I want to know how can any such database errors be handled gracefully? Can these be handled by a fault handler?If so, how?
Thanks!

You can use a catch/catchAll around the scope where these database related activities are happening. Within the Catch/CatchAll block, you can decide and provide the logic for a retrial or termination of the process or any other behaviour that you want.

Tried opening a file in library and it states can't open database with library name? It says Relaunch then will not open? and Blocks me completely from Aperture. I have to go to Finder to Rename it? I need this file how do I get it to open?

Aftershotz,
You're going to have to give a bit more information.
What do you mean by "opening a file in library?" There is no function of Aperture to open files -- you can open (switch) libraries.
You'll have to be more specific about error messages, too. Perhaps some screenshots would be useful to diagnose your problem. "Can't open database with library name" is not enough detail about what Aperture is really telling you.

How i can associate my app user with database role

In my application (oracle forms application developed in-house - We are using Oracle Forms 11gR2 with WebLogic 10.3.5 ), i want to use "application user" instead of database user.
I have an application users table, actually, i have database users,and of course, menu application works with database roles (It was developed with oracle forms menu module), my question is, How i can associate my application user with database role, for reusing oracle forms menu funcionality?. It's possible?
Thanks,
Edward

Hi Edward
You can do this by assigning the role functionality to the application user. For example
create the table to enter user name.
create table to enter group name.
create table to assign user to group.
assign role to group.
assign functionality for the user by coding.
hope this helps

How I can store Image file in a database

Can any one how i can stored image file in a database and then by using same database how i can show in HTML page...(in a browser)

This is not something that can be answered easily. There is quite alot of code involved....
To get started I suggest you read up on the built-in package 'DBMS_LOB' from Oracle . Most of what you need you should find there.

Saeed,
I am not sure that I understand your question. You want to upload your database to the internet?
If that is the question, then you may want to use Oracle 9iAS Portal to pull information from your database and display them on the web.
Hope this helps,
