Does Result Cache Really Work..

Does Result Cache Really Work..
We have upgraded to 11.2.0.2 Theere were some corruption issue we were facing cause of using result cache..
Still the same error after upgrade...
Is any one here familiar with using result cache..One good thing about result cahce i found it does improve performance.
But the problem is the datbaase crashes..after it reaches some memory limit..Does any one have good expereince using it..?

Probably following notes on Oracle Support site can help.
11g New Feature PL/SQL Function Result Cache [ID 430887.1]

How does business catalyst really work?

So i've tried to reach this and cant seem to find answers in plain english.... How does Business Catalyst really work?.. functionally.
1) I have a hosting service with godaddy and jumpline, I have a lot of space and do all of my client's websites through the space I have with those two plans, do they offer the business catalyst format? Just buy that platform with them or have it added?
2) I have CC, business catalyst "comes with" it.... how does that work? Am I given space on someone elses server somewhere or do I just have the ability to upload the BC software onto a server I have... in which case could it be uploaded to godaddy or jumpline?
3) The new MUSE features can only be done with business catalyst right?

Hi,
Business Catalyst is a web hosting platform that lets web designers host, build, and sell websites to clients. You use Muse to create and update a website. You use Business Catalyst to host it. A Muse subscription includes free hosting on Business Catalyst for one site. A Creative Cloud membership includes free hosting for five sites.
Regarding your Creative Cloud Subscription, with BC. You must install and use Muse/Dreamweaver to publish your free sites. For More details, Please refer to the article below
http://helpx.adobe.com/business-catalyst/using/business-catalyst-muse-users.html
The new Muse feature, like in Browser editing is compatible only with Business Catalyst, but the other feature like Parallex Scrolling works on all the other hosting as well, like Godaddy.
If you still have any query, please let us know and we will try to resolve it.
Thanks.

Does Memory Clean really work?

There is this app called Memory Clean, which apparently clears up ram. Does this really work, and if it does, how?

it runs the terminal command "purge"
which you can do by yourself without the need of softawre.

Result cache not working?

Hi,

result_cache_max_size big integer 10M

result_cache_remote_expiration integer 0
The above are the initialization parameters set and the DB version.
Now i have created a table as
create table objects as select * from dba_objects;
then issued the following query.
select /* result_cache */ object_Type,count(*) from objects group by object_type;
it appears that the results of the above query is not cached in the result cache. using
set autotrace traceonly explain confirms that there is no result cache or the CACHE_ID in the explain plan. also the v$result_cache_statistics confirm the same.
But after this when i issued the following statement.
alter session set result_cache_mode=force;
the same below sql statement again
select /* result_cache */ object_Type,count(*) from objects group by object_type;
it appears that now the result cache is being used.
My question is despite using the result_cache hint and trying the above statement when the result_cache_mode=auto/manual. The result cache is not being used or the results of the SQL statements are not being cached at all despite using the result_cache hint and the table being not used at all. and if i use the result_cache_mode=force then the result cache is being used.
Can any one please explain this behavior. Cursor_sharing is set to EXACT. and i am issuing the same SQL statement without any changes at all.
Thanks,

There is a syntax problem with your queries:
select /* result_cache */.... is just a comment, not a hint. For creating a hint, you need "+": select /*+ result_cache */....

Does this program really work?

I got this link for a convert program from this forum but I don't want to buy it unless I know its going to work. I already got QT pro just to find out that it didn't convert my files right and now i'm stuck with it.
http://www.divmm.com/
The program is called Video Vault, it clames to convert DVDs, VCDs, SVCDs, Analog/Digital Camcorder Tapes. Files types = AVI, Mpeg1, Mpeg2, Mpeg4, ASF, WMV, DVR-MS, TIVO, VOB
Most of the video formats I have are AVIs and MPEG1s and nothing else seems to do it right so if anyone has used this program can you please tell me if it really works?
thank you

DOES BLACKBERRY LINK REALLY WORKS?

HI, I HAVE A Q10 AND I IT STOPPED WORKING SINCE THERE WAS AN UPDATE AND I AM NOT ABLE TO SYNC MY MEDIA AT ALL. I READ SOME POSTS AND I'VE TRIED TURNING OFF THE WIFI FROM THE DEVICE BUT STILL DOES NOT WORK. I HAVE A MAC BOOK AIR. CAN ANYONE GIVE ME ANY TIPS??? I REALLY APPRECIATTE.

Hey Evna,
Welcome to the BlackBerry Support Community Forums.
Thanks for the question.
This is a very bizarre issue as there is no known issues between Outlook 2003 and BlackBerry Link. I would suggest disabling the BlackBerry Virtual Private Network and then test the Microsoft Outlook connection.
Also if you connect the BlackBerry Z10 without BlackBerry Link opened, do you see any problems happening in Outlook?
I look forward to your reply.
Cheers.

How does Calendar.setFirstDayOfWeek really work?

If you run the following program you get the same output from both calendars. Is that really how it should work or is it a bug?
import java.util.Calendar;
import java.util.GregorianCalendar;
public class CalendarTest {
public static void main(String[] args) {
Calendar europeanCalendar = new GregorianCalendar();
europeanCalendar.setFirstDayOfWeek(Calendar.MONDAY);
Calendar americanCalendar = new GregorianCalendar();
System.out.println(americanCalendar.get(Calendar.DAY_OF_WEEK));
System.out.println(europeanCalendar.get(Calendar.DAY_OF_WEEK));
}

Hmm, maybe. So the only way to actually use
setFirstDayOfWeek is via the getFirstDayOfWeek
method?
I was under the impression that
setFirstDayOfWeek(MONDAY) would re-number the day
constants (MONDAY, TUESDAY etc.) so that MONDAY would
have the value 1 instead of SUNDAY.Er, no. They're constants. They can't be renumbered. That's what the "final" in their declarations mean.

Does DataGrid.indexToItemRenderer really work?

Let's say I have a two column DataGrid. I want to get the
itemRenderer for the cell at the third row in the second column.
Shouldn't this work?:
var rendererIndex:int = dataGrid.indicesToIndex(2 1);
var renderer:IListItemRenderer =
dataGrid.indexToItemRenderer(rendererIndex);
It doesn't appear to be working, however. When I debug it, it
returns the itemRenderer for the cell at the thrid row, but for the
FIRST column. Why doesn't this do what you think it would?

Hello, was looking for the solution to a similar problem and I came up with a solution:
public function indexToItemRendererAtColumn(index:int, columnIndex:int = 0):IListItemRenderer
     var firstItemIndex:int = verticalScrollPosition - offscreenExtraRowsTop;
     if (index < firstItemIndex ||
            index >= firstItemIndex + listItems.length)
            return null;
        return listItems[index - firstItemIndex][columnIndex];
In my extended component of a DataGrid I added this method which uses most of the code from the indexToItemRenderer method of the ListBase class. The original Adobe code explicitly uses the column at index 0, this simply uses the specified columnIndex to return the item renderer you desire.

JMSUtils - does this utility really work?

I'm back to doing battle with JMSUtils to analyze my JMS situation on Oracle AS 9.0.4 Enterprise Manager version. I just can't figure out where they want me to configure the admin user to access the tool. I'm getting this error:
C:\oraAppServer\j2ee\home>java -cp ./oc4j.jar com.evermind.server.jms.JMSUtils -username admin -password welcome durables
Oracle Application Server Containers for J2EE 10g (9.0.4.0.0) (build "040317.1838"), OC4J JMS 1.0.2b

Any help out there?

Here is the command:
java com.evermind.server.jms.JMSUtils [gen_options] [command][command_options]
An example of using JMSUtils to browse the exception queue is as follows:
java com.evermind.server.jms.JMSUtils -username admin -password welcome
browse jms/Oc4jJmsExceptionQueue
For topics
In order to listen to a topic you will first need to set a durable subscription (using JMSUtils), then publish some messages (using whatever publisher you have) and finally retrieve these messages (browsing using JMSServerUtils).
1. set a durable subscription
To create a durable subscriber to browse / drain the topic, you need to do the following:
java com.evermind.server.jms.JMSUtils -username admin -password welcome subscribe -name "Debug1" "Demo Topic"
Note that the name comes after the subscribe, but before the Topic name.
2.publish some messages on that topic
3. browse messages
java com.evermind.server.jms.JMSServerUtils -username admin -password welcome browse -name "Debug1" "Demo Topic"
Make sure you use the same clientID (if you specify one) and name in both the subscription and the browsing. These are JMS concepts: clientID identifies a connection factory and name a specific subscription on this connection factory.

Does the Powerbook really work with Leapard? Ever since I installed...

my fan is running NON STOP. And the computer is hot. I looked at the activity monitor and nothing seems out of whack (I am using firefox and word). I just ran into a friend who described the same problem after she upgraded. Should I be re-installing Tiger?
Thanks!

Leopard is more demanding of hardware resources than any earlier OS version. You should expect your machine to run hotter and/or the fan to run more and faster. If you can't stand the fan noise and the heat, you may indeed want to go back to Tiger. It's a better match for your machine than Leopard is, certainly.
Note, however, that if you have just installed Leopard, Spotlight may still be indexing your hard drive: a highly CPU- and disk-intensive process that generates a lot of heat. If that's going on now, wait until it finishes to get a better indication of what temps and fan operation will be like in normal usage.

Does Webutil 106 really work with forms10g 10.1.2.0.2 ?

Hi. I'm unable to run webutil 106 with Forms Developer 10g 10.1.2.0.2.
I have performed all installation steps, but can´t launched any demos neither use any of the cool features. I was told previously on this forum that it was not possible for this forms version although OTN says the opposite.
Checking the installation guide, one can notice that many references to "forms90/" or f90xxx( f90all_jinit.jar, etc.) . That won't happen for forms10g. I have tried to manually change this for the correct reference, but still have not succeded.
Who's right here?. Any workarounds maybe???
Thanks in advance ...!

The download for WebUtil contains an html file in the doc directory which goes through the installation process step by step. Is this the one you followed to do your installation? The one step it misses is setting archive_jini, which you can find in <forms home>/forms/server/formsweb.cfg. This setting tells jinitiator which files it needs to load to provide the functionality of the java beans and PJCs specified by your forms. For WebUtil the files are frmwebutil.jar and jacob.jar.
The html file also talks about what the directory names should be in different versions of forms and the differences between installing on Development servers or full-blown Application servers. I've only followed the steps to install it on 9iDS but apart from archive_jini I had no problems.
I'm not sure what demos you mean, but if you want to check that WebUtil is installed correctly then calling a function like Create_Directory would be a good way. If it creates the directory then you're up and running.

Oracle result cache and functions

Hi All,
I am on 11.2 in Linux.
I want to use Oracle's result cache to cache results of (user defined) functions, which we use in SELECT commands.
My question is, does result caching work for deterministic and non-deterministic functions ?
Just curious, how Oracle keeps track of changes being made which affect a function's return value?
Thoughts please.
Thanks in advance

I want to ... cache results of (user defined) functions, which we use in SELECT commands.You have four choices:
1. Subquery caching - (wrap function call in SELECT) useful for repeated function calls in a single SELECT
2. Marking function as DETERMINISTIC - inconsistent results across versions, deterministic best reserved for function-based indexes only
3. Result Cache
4. Move function logic out of function and inline to the main SQL statement.
The biggest downside of any function call that is inline to SQL is that it bypasses the read consistency mechanism, actually that's probably the second biggest downside. The biggest downside is normally that their misuse kills performance.
If your function itself contains SQL then you should seriously reconsider whether you should be using a function.
does result caching work for deterministic and non-deterministic functions ?Result cache knows nothing about determinism so yes it should be applied regardless.
Oracle keeps track of changes being made which affect a function's return value?See v$result_cache_dependency.
The mechanism is very blunt, there is no fine-grained tracking of data changes that may affect your result.
It's as simple as function F1 relies on table T1. If the data in table T1 changes, invalidate the results in the result cache for F1.

OSB - Result Caching

Hi,
How do I confirm if the result caching is working? This is on the latest download available for OSB - 11.1.1.3.
I tried to launch separate instances of caches, but could not confirm. Secondly, I also tried to enable caching support for a business service. I put in a hard coded expression in the cache token expression. I was not able to get that working.
Any ideas?
Regards,
Anand.

Perhaps the simplest way is to check access log on your backend (business service). Arrange a simple test that will lead to repeated callouts (with the same request data) to your business service. Than you should see only one (the first) request logged in your backend.
The better way is to start another node of Coherence, connect to the OSB instance of Coherence and see what your cache looks like. Look at Coherence documentation for command line parameters:
http://coherence.oracle.com/display/COH35UG/Command+Line+Setting+Override+Feature
I was able to connect to the default OSB Coherence instance and list cached entries using this command:
java -Dtangosol.coherence.cluster=OSB-cluster -Dtangosol.coherence.clusteraddress=228.8.8.8 -Dtangosol.coherence.clusterport=9888 -Dtangosol.coherence.distributed.localstorage=true -Dtangosol.coherence.override=/opt/Oracle11g/user_projects/domains/osb11_domain/config/osb/coherence/osb-coherence-override.xml -Dtangosol.coherence.cacheconfig=/opt/Oracle11g/user_projects/domains/osb11_domain/config/osb/coherence/osb-coherence-cache-config.xml com.tangosol.net.CacheFactory

HT5343 Resetting the DNS cache does not seem to work on OS X 10.8, what does really work?

Resetting the DNS cache does not seem to work on OS X 10.8, what does really work?
Desired activity: access a site that used to not have a SSL connection through the new https:// root domain. I can accomplish the task over a machine running Windows 7 or XP but flushing the dns of my mac does not affect the outcome — I am still redirected to the hosting provider's website whenever I tried to access the domain with a https:// prefix rather than http://
I tried sudo killall -HUP mDNSResponder and it's older alternative but no luck.

In the terminal:
dscacheutil -flushcache
and to get a very detailed report on the state of your DNS cache in /var/logs/system.log:
sudo killall -INFO mDNSResponder
