Aggregates not in use

Hi,
How to get the list of the aggregates which are currently not in use, without going to the aggregates maintainence screen?
Thanks

Samruddhi,
Did you try in LISTSCHEMA?

When are aggregates not used???

Hey All,
I have a question concerning aggregates and when they get used. I have a user running a query and specifiying values in the selection criteria for the following:
- Sold-to Party
- Distribution Channel
- Site
- Condition Type
- Calendar Week
All 5 of these Characteristics are part of the new aggregate I build. I guess I don't understand why the aggregate is not being hit, if they're reporting on the exact same Characteristics that are part of my aggregate.
Can anyone explain????
Much appreciated.
John

John,
For an aggregate to be used all of the following have to be true:
InfoObjects in the Rows must be included in the aggregate
InfoObjects that have restrictions on them (Rows, Filters, FCs, KF Columns) must be included in the aggregate
InfoObjects that are referenced as part of exception aggregation
No Virtual KFs in the InfoProvider
No 'Before aggregation' calculations on the CKFs
I believe that is the complete criteria.

Index not being used in access path

Hi,
I have been trying to rewrite a query which currently is taking almost 1min and 25 secs to execute. The database version is 11.1.0.7.
The query is -
SELECT COUNT(1)
FROM TAB1 p
WHERE p.ACODE = 24377
AND NOT EXISTS (SELECT 1 FROM TAB2 ph where ph.PKey = p.AKey )
AND NOT EXISTS (SELECT 1 FROM TAB3 phs where phs.PKey = p.AKey )
AND p.rflag = 'Y';
The table originally didn't have an index on p.ACODE. So, I created this index and set it to visible and set the optimizer_use_invisible_indexes parameter also to TRUE. I set the monitoring on this index too. Even though I have created the index on the ACODE column, the access path doesn't use it. Can someone please tell me why this is not being used.
Below is the explain plan for the sql stmt and the usage of the index -
I have changed the actual table and column names -
SQL> SELECT COUNT(1)
2 FROM TAB1 p
3 WHERE p.ACODE = 24377
4 AND NOT EXISTS (SELECT 1 FROM TAB2 ph where ph.PKey = p.AKey )
5 AND NOT EXISTS (SELECT 1 FROM TAB3 phs where phs.PKey = p.AKey )

Thanks Centinul.
I apologize for posting in both sections. I put it in the Database General too because I thought I originally posted it in the wrong section.
The index was not being used because it was doing the implicit type conversion. When I enclosed it in quotes, it returns the result within a second and it uses the index.(whereas without the index it takes around 1min 25 sec)
Here is the explain plan and execution time after enclosing it in quotes -

the actual names are 'scrubbed' for obvious reasons. Don't worry, I didn't name the tables in mixed case.

Jonathan,
Thank you for your input. Forgot about this issue since ended up creating an MV since, the view was slower. But either way, I am curious. Here are the results for your questions.

No other data came into the table after.
Also,
1). I thought I don't have any particular optimizer parameters, but, checking back I do. fastfull_scan_enabled = false. Could that be it?

PS: This has nothing to do with original question, but, it is plausible to derive the 'huge_data' table name from the sql_id? Just curious.

Aggregate not hitting

Hello Friends,
I am trying to create an aggregate for Income Statement Query.
On the filter I have Fiscal Year Variant, Currency type and Chart of Accounts
On the Free Characteristics I have Profit center, company code and Fiscal year period.
I tried different ways on the Characteristics with fixed values and hierarchy(account no) but the aggregate is never used when executed the query. Can anybody give some input
thanks

Hi
If your aggregate are not hitting
Please ask the User to send me Book mark how he is drill down the query
Check with rsrt tcode how you aggregate is defined
copy the aggregate which is hitting ur aggregate and
apply Fixed for Company code value type ,version,Hierarchy level set and
chech
rsddstat,rsddstataggrdef and RSDDAGGRDIR tables

Hi adityabhargava01-
My first suggestion is to upgrade to the most recent version of Firefox by going to this link:

My second suggestion is to read this article on how to many your preferences on how Firefox deals with PDFs and all other file types:
[[Options window - Applications panel]]
I hope that helps!

AdobeAcrobat/Reader that is running can not be used to view PDF Files in Web Browser...what do I need to do to fix this..

I just got Windows 7 and have been having problems since loading it. Most of my drivers only go to Vista and don't recognize 7.
I have trying to download some manuals from their website
and keep getting this message; Adobe Acrobat/reader that is running can not be used to view PDF files in Web Browser.

Could I suggest a workaround for PDFs until a solution is posted? Open them directly in the Adobe application rather than in a browser tab.
In your Adobe application(s), go to:
Edit > Preferences > Internet
Then uncheck "Display PDF in browser"
(There are very few sites where having PDF integrated is really beneficial.)

I can't view PDF files via Chrome (it works on Internet Explorer but I prefer Chrome) - the error below has arisen recently on Chrome, though I can't see what has changed.
"Acrobat plug-in

I have looked through Forum articles on similar errors and have tried the following(text copied from other Forum entries)

None has solved the problem. However it still works ok with IE. But I want to stick with Chrome because I find IE is so slow!
I am using Vista, with Adobe Acrobat standard 9.5.2 and Google Chrome version 23.0.1271.64 m which is marked on Chrome as 'up to date'
Does anyone know why I might be getting this error on Chrome but not IE?

I think I have discovered the answer to my own question!
I have disabled Adobe Reader plug-in, and can now see PDFs in Chrome.
(Steps: Chrome Menu, Settings option, Click Advanced Settings link, then Content Settings button, then select Disable Individual Plug-Ins, and a list of plug-ins is offered to enable or disable).
I then get a different result depending on whether or not Chrome PDF viewer is enabled - with it enabled I see the PDF document in Chrome, or with it disabled then the option is offered to download it, but either way I can get it it via Chrome without having to run Internet explorer in another browser window.

Reader 9.2 - "can not be used to view PDF files in a web browser"

Hello,
I recently deployed Adobe 9.2 within our organization. I used the Adobe Customization Wizard 9 to transform the install set, and selected the "Display PDF in Browser" option as default.
When opening a PDF linked from a web URL, we get the message: "The Adobe Acrobat/Reader that is running can not be used to view PDF files in a Web Browser. Adobe Acrobat/Reader version 8 or 9 is required. Please exit and try again." This occurs under IE8 and IE6, in both Windows XP SP2 and Windows 7.
If I launch Adobe Reader and unselect "Display PDF in Browser" in preferences, PDFs open normally.

Does any one came accross the following message trying to view PDF's in web browser? "Adobe Acrobat/Reader that is running can not be used to view PDF documents in Web browser. Please exit the Acrobat?Reader application and try again". Thanks for your help! Barbara

A function can not be used in Applet.what's wrong?

Here is a function.
private String LoadFile() {
String input;
String output="sssssdsdsddf";
try{
FileReader f=new FileReader("shu.txt");
BufferedReader in = new BufferedReader(f);
while ((input = in.readLine())!= null){output=output+input;}
in.close();
}catch(IOException e) {
System.err.println("Exception caught: " + e.getMessage());
return output;
It can be used in Java Application,and work well.but can not be used in Applet,it does not work.what's wrong?

Don't you think it would be a bit of a security risk if any applet you downloaded from the web (unknowingly) could read/write to your file system....
Applets have strict security applied to them, and file i/o is one of the restrictions. There are ways around it, but for the moment I'd suggest you build a bridge and get over it.

You need to get the owner's manual for your Ford's bluetooth system to see how to put your system into discovery mode for the iPhone as well as the appropriate steps to take.
In addition, you should see if the iPhone is supported.

Materialized view not being used in the report

I have had a materialized view (MV) for a particular report. Recently, the report definition has changed little bit, so the existing MV is not being used by the report anymore. I copied the code Discoverer's SQL Inspection and recreated the materialized view. But still it is not working. Obviously, I am missing something at the database level. Does anyone have any idea? The database is 9i and Discoverer is 9.0.2. Thank you!

The SQL that you see from the Inspect SQL option will provide you with the SQL that Discoverer sends to the database. The database then may do a query rewrite to point to an available materialized view if available. This rewrite won't be seen from the inspect sql option. You need to check at the database level to verify if a query rewrite did in fact take place.
You may want to check the section titled "Query Rewrite with Materialized Views" from Ch1 - "Introduction to the Optimizer" in the Oracle9i Database Performance Tuning Guide and Reference, Release 2 (9.2), Part Number A96533-02, available at http://download-uk.oracle.com/docs/cd/B10501_01/server.920/a96533/optimops.htm#37287
