Can we know which DBs are having access through DBLinks to local DB?

Gurus,
Is it possible to know which DBs are linked to our local DB using DB Links?
e.g.
There are 2 DBs Database1 and Database2 having schemas Schema1 and Schema2 respectively.,
Schema1 in Database1 is having a DBLink DBLink1 which connects to Schema2 of Database2.
Hence, by logging into Schema1 a user can access the objects of Schema2 in Database2 ( assume that appropriate privilages are granted)
If "I" have access to Database2 only, then is there any way that will tell me that Database1 is having access to Database2 using the DBLink1...like wise?
Please Guide-
Thanks in advance!
-Abhijit.

Thanks Martijn,
It seems the views specified in the link you provided provide the information of DBLinks that have been defined at the local database.
But, I want to know which remote DBs are accessing my local DB using DBLinks?
Pls Guide.

How can I know which clients are connected to my network through express and which are connected through extreme?

I have an airport express extending, through wireless, a network provided by an airport extreme. How can I know which clients are connected to my network through express and which are connected through extreme?
Here you can see both routers:
I would expect to some clients connected to the express, other than the extreme. And that's all I see: only the airport extreme appears as client of the airport express.
Below, one can see the summary of the config for both routers.
Would somebody explain it?
Thanks,
Marcelo

How can I know which photos are in the library was used in each album I have created before?
I have many photos in the library folder of iPhoto, but actually I don't know which photos were used in my album.
Is there any method to find this?
Thanks.

How can I know which nodes are doing what?

I have QMaster helping with a Compressor job, is there a way I can tell in the Batch Monitor (or maybe somewhere else) which nodes are working on the task?

Thanks. Problem is that Apple Qadministrator tells me that information is not available for QuickClusters. Since I just let Qmaster sortof set itself up, that's what it is, a QuickCluster.

How can I find out which tables are having DDL locks?

I can see related information by querying DBA_DDL_LOCKS view, but it doesn't give me the information which tables are having DDL locks.
Is there a way I can find out which tables are having DDL locks?
Thanks!

How to get Retro for a period or how to know which month is having retro

Dear Freinds,
I would like to know how can i know which month is having Retro .
Iam reading from the FM cu_rgdir and further iam using PYXX_READ_PAYROLL_RESULT to get the payroll results.
But when we see pc_payresult if we have for period not equal inperiod there is a retro . Could any one please let me know
the functional module which retrives and gives me the Retro result .
Or i mean to say how i can read the retro results through my coding please could any one guide me in this regard.
Regards
divya

This function does all the work :
HR99L00_GET_RETRO_MONTH_DIFF
You just need to input the wages you want retro of and it will give you the values of retroactive payroll results.
the logic behind it is always a headache to do by hand, but basically it will compare the retroactive month to the previous result for that month and calculate the differences between the wages (say for example wagetype 0001 had 1000,00 in INPER 201105 FPPER 201105 and 1500,00 in INPER 201106 FPPER 201105 it will bring in this function for wagetype 0001 500,00 for period 201106).

How can I identify which albums are associated with a specific picture. I used to click on the picture and see the albums but don't know how to do it in 13?

I keep pictures in Albums, specifically by year and then other topic albums. As a result some pictures are in several albums. Sometimes they are assigned in error. I used to be able to click on a picture and see not only the tags but the albums associated with the picture. How can I see which albums are assigned to a picture?

Are you referring to the yellow text box that pops up like this?
If it is those are called tooltips or anchor titles. Cyclosaurus has posted script to block them: removing rollover html detail box: Apple Support Communities.

I have apps on my iPhone that I want to delete but do not want them deleted from my iPad. How do I know which ones are iPhone specific?

In order to save using data when traveling I want to delete apps from my iPhone that I don't need. However I do want these apps on my iPad and with the new IOS8.0.2 and Yosemite I think they are all now integrated so that if I delete from one device it is deleted from all and if I add to one device it is added to all. Is this correct?
1. How can I tell which apps are specific to iPhone and which are specific to iPad?
2. How can I tell how much data is being used per app?
3. How can I tell if an app is running in the background?
4. When I turn off cellular data does that limit the app from functioning always or just restrict it to wi-fi?
5. Do I benefit from having Bluetooth on if I don't use a head phone or other device?
6. Is a Personal Hotspot more secure than using paid hotel wi-fi?

Deleting on one device does not affect another device.
You can delete the App's on the iPhone and nothing will happen to the ones on the iPad.
1. You don't need to.
2. Settings->Cellular->"Use Cellular Data For" will show the data usage for each App since the last statistics reset
3. Settings->General->Background App Refresh Will show which Apps are allowed to get data in the background
4. It restricts it to Wifi. If the App requires internet access and Data is turned off, it will have to wait until the device is connected to a wifi network.
5. Nope, You just use up battery since the BT radio will continuously look for nearby BT devices.
6. The Personal Hotspot uses your cellular internet connection from your phone or other cellular device; whether you consider that secure or not I cannot say. It also depends on what you are doing while connected to the Hotel's wifi. I would not do online banking while on vacation though.

How can I know which link was clicked in the link list

Hi everyone
I'm using list of links in my page to display list of the files in some directory.
How can I know which link user was clicked. There are some code:
<%
String dir = "..//files//";
File fin = new File(dir);
File files[]=fin.listFiles();
for(int i=0;i<files.length;i++)
File x = files;
%>
<%=x.getName()%><br>
<%
%>
Please help

You need to pass some data on the querystring to the page you are linking to.
<a href="Main_Work.jsp?file=<%=x.getName()%>"><%=x.getName()%></a><br>
This will send a parameter called "file" with the value of the file name that the user clicked.
Now in Main_Work.jsp you can access this data as follows:
<%
String s = request.getParameter("file");
File f = new File("..//files//"+s);
%>

In I06, I have no way of knowing which songs are on my iphone 4s vs being stored in the cloud. There used to be a small cloud next to songs that were not downloaded. This was important to make sure I had the music I wanted when in an airplane.

In the new i06 that I just loaded into my 4s, I have no way of knowing which songs are on my iphone vs stored in the cloud. There used to be a small cloud next to songs that were not on the phone. This is an important piece of information if you are a frequent traveller, as most of the flights I am on don't have onboard wifi, so it becomes a crap shoot as to what I will have available to listen to.
Is there a way I can view what songs are actually stored locally?

Go to Settings > Music and set "show all music" to OFF.

HT4914 How can you tell which songs are downloaded from the cloud on an ipad

How can you tell which songs are downloaded on the iPad from the cloud?

I know ipad albums are more like tagging photos rather than putting them in folders. I just have a nagging feeling I missed some pics and I have too many to try to go figure out one by one. I don't look at my photos from the camera roll, only from albums I tagged just because I imported photos from different sources and the dates and order is really messed up. I just want to know that I am viewing all the photos from like this vacation or that event and there's none I missed that are only in the camera roll.

How can i know which version of Smartview is installed on my system ?

Hi All,
How can i know which version of Smartview is installed on my system ?

Do you know what version of Essbase you are running? that could help. You can find that in EAS. Right click on the server name and select edit ptoperties, then look on the environment tab. As a final measure, find the smartview.exe on yout machine right click and select properties. in one of the tabs there might be a version number

How to know which interfaces are going to which switch?

How to know which interfaces are going to which switch ?
I know that cdp will show this information. But CDP will not show info about the devices connected to my device and whose link between is administratively down.
Regards,
Chandu

I don't want to the end devices location.
For example, i have a switch that connect to multiple switches few using etherchannels and few using stand-along ports.
So assume that one of the link whether it may be entire port-channel or a stand alone link that connects to another switch has been shut down manually by some x person...
Then how can i know that which interfaces are connecting to that switch. In this case i think CDP will not help because it will hold the information of ports that are up.

Chandu

How can i know which index will be used when executing the query ?

1 ) I have query in which i have 3-4 tables but there multiple index on one column .
so how can i know which index will be used when executing the query ?
2) I have a query which ia taking too much time . how can i know which table is taking too much time ?
3) Please Provide me some document of EXplain plan ?

Hi Jimmy,
Consider the below example
/* Formatted on 2011/02/04 21:59 (Formatter Plus v4.8.8) */
CREATE TABLE FIRST AS
SELECT * FROM all_objects;
UPDATE FIRST
SET object_name = 'TEST'
WHERE owner != 'SCOTT';
CREATE INDEX idx_first ON FIRST(object_name);
SELECT *
FROM FIRST
WHERE object_name = 'TEST';
It has not used index
Execution Plan
Plan hash value: 2265626682
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 58678 | 7334K| 163 (4)| 00:00:02 |
|* 1 | TABLE ACCESS FULL| FIRST | 58678 | 7334K| 163 (4)| 00:00:02 |
/* Formatted on 2011/02/04 21:59 (Formatter Plus v4.8.8) */
SELECT *
FROM FIRST
WHERE object_name = 'emp';
This has used the index
Execution Plan
Plan hash value: 1184810458
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 1 | 128 | 1 (0)| 00:00:01 |
| 1 | TABLE ACCESS BY INDEX ROWID| FIRST | 1 | 128 | 1 (0)| 00:00:01 |
|* 2 | INDEX RANGE SCAN | IDX_FIRST | 1 | | 1 (0)| 00:00:01 |
From this we can come to the conclusion that, whether to use one index or not by oracle
would also depend on the data which is present in the table. This has to be this way as
we see in the bind peeking, if oracle sticks to only one plan, say only use the full table
scan, it would be a performance hit when it searches for the second query ie where object_name
='emp';
2.
If we have a query like below.
select * from emp
where upper(ename) = upper(:p_ename);
Evenif we have the index on ename column, oracle wouldn't be able to use the index, as there is a function in the predicate column. If you need oracle to use the index, we need to create a function based index as below.
Create index idx_ename on emp(upper(ename));

Cool

How can we know which index is triggered

hi all ,
how can we know which index is triggered in perticular select statement ? is that just based on the fields which used in the select statement or can we know from ST05 ?
thanks,
ram

Hi Ram,
You can go to transaction ST04(if you are authorised)...
Now select 'Detail analysis menu' button.
Now select SQL Request button under 'Resource consumption by' section.
Now in the ' SQL statement pattern by ' field , give the part of the select statement you want to check.
Now press execute.
Now select the line item displayed and goto menu option <b>Goto->Explain SQL</b>.
It will give you the execution plan for the particular SQL statement.
From here you can get the index values from INDEX RANGE SCAN statement in this output.
Hope this has been of some help to you...
Regards,
SP.
