GV$session_longops - Time_Remaining shown as 0

Hi,
I have a query joining 4 tables and it returns 48 million. I have used /+parallel(tablename,4) */ hint with the select clause. I want to the 48 million returned by the query to another table t2.
I do get the select result in 20 minutes. when I am performing insert, I checked gv$session_longops. I usually check like select * from gv$session_longops where time_remaining>0.(http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:30141363147028) .
It didnt return anything. I removed the where clause and rather gave the sid.(i found the sql_id from gv$session)
select * from gv$session_longops where sql_id='XXXXXXX';
I got 3 rows but time_remaining column is 0. Could someone explain why this is so.

Good question, but I do not know if there is a straight-forward answer to your question. Maybe we should start with a documentation reference:
http://download.oracle.com/docs/cd/B28359_01/server.111/b28320/dynviews_3021.htm
"V$SESSION_LONGOPS displays the status of various operations that run for longer than 6 seconds (in absolute time)."
You will notice that the definition includes SQL_PLAN_LINE_ID, which refers to a specific line in an execution plan. From this bit of information, we just need to define what is considered an operation (and does it have to be an uninterrupted operation) - without parallel query we might be able to perform a couple of tests.
Consider the following query:
SELECT
T3.C1,
T3.C2,
T4.C3
FROM
T3,
T4
WHERE
TRUNC(T3.C2) BETWEEN TO_DATE('08-MAR-2009','DD-MON-YYYY')
    AND TO_DATE('01-JUL-2009','DD-MON-YYYY')
AND T3.C2=T4.C2;If we set the STATISTICS_LEVEL to ALL at the session level, run the SQL statement, and then generate the DBMS_XPLAN for the last execution, we may see something like this:
SQL_ID 2d4f5x92axqgn, child number 0
SELECT    T3.C1,    T3.C2,    T4.C3 FROM    T3,    T4 WHERE
TRUNC(T3.C2) BETWEEN TO_DATE('08-MAR-2009','DD-MON-YYYY')      AND
TO_DATE('01-JUL-2009','DD-MON-YYYY')    AND T3.C2=T4.C2

Now assume that in another session we executed the following SQL statement roughly every 6 seconds while the above SQL statement was in the process of being executed:

no rows selectedFrom the above it appears that the full table scan of table T3 required between 148 and 154 seconds, and then no rows were listed by the SQL statement for roughly 6 seconds before V$SESSION_LONGOPS started reporting that table T4 was being read. From the above it appears that the read of table T4 required between 86 and 94 seconds, yet that does not agree with the DBMS_XPLAN output (it appears that the hash join operation's time is being reported as part of this elapsed time in the V$SESSION_LONGOPS output).
Let's take a look at another SQL statement:
SELECT
T3.C1,
T3.C2,
T4.C3
FROM
T3,
T4
WHERE
T3.C2 BETWEEN TO_DATE('08-MAR-2009','DD-MON-YYYY')
    AND TO_DATE('01-JUL-2009','DD-MON-YYYY') + (1-1/24/60/60)
AND T3.C2=T4.C2;This statement is equivalent to the previous SQL statement, except that it is able to use the index that exists on table T3. The execution plan follows:
SQL_ID 539d93k50ruz3, child number 0
SELECT    T3.C1,    T3.C2,    T4.C3 FROM    T3,    T4 WHERE    T3.C2
BETWEEN TO_DATE('08-MAR-2009','DD-MON-YYYY')      AND
TO_DATE('01-JUL-2009','DD-MON-YYYY') + (1-1/24/60/60)    AND T3.C2=T4.C2

no rows selectedAs you can see from the above, the parallel query processes (each with a different SID) appear in and disappear from the V$SESSION_LONGOPS output as the query executes.

V$session_longops not displaying a long running query

Hi,
There is a certain query that runs as a part of a stored procedure which when run takes about 1 and half hours to get completed and there is a hint in this query to use certain indexes on few tables.
This time was unacceptable as it was much much longer than what it should have taken so I tried to monitor it through v$session_longops using the following query
select * from v$session_longops where time_remaining > 0
It shows no rows selected but the query is still running.
When I changed the hint in the query to use the full table scan on these tables instead of the indexes it began to show up on the v$session_longops and it took like only 15 mins for the procedure execution to get completed.
My questions are two fold
1) Why did the first time with the Hint on the indexes not show up on v$session_longops with time_remaining > 0 and why did it show up only when i did a full table scan?
2) Secondly is'nt a scan on a table faster using indexes if the index has unique values on the columns we are trying to get data from than the Full Table Scans. And if so then why is it behaving differently in this case.
Thanks a lot in advance for any answers/suggestions

1. v$session_longops only reports long running operations. The CBO assumes that the index scan is a tiny operation (nested loop joins), hence it is not displaying the query, but when you have a full table scan, the CBO assumes this to be a long operation, and hence it is visible in v$session_longops.
2. Allow me to quote from
"http://asktom.oracle.com/pls/ask/f?p=4950:8:17968334624783495563::NO::F4950_P8_DISPLAYID,F4950_P8_CRITERIA:9422487749968"
"full scans are not evil, indexes are not good"
"full scans are not evil, indexes are not good"
"full scans are not evil, indexes are not good"
Click that link for more information. :)
The gist of it is, your CBO is smart, and hence generating a better plan than when you force it to use indexes. Yes, the plan has full table scans, but that is not a crime. What you can do is use optimizer parameters - "optimizer_index_cost_adj" to tune for a better performance, but you should not force an index unless you are sure that the index gives you a lower cost.
You could paste the plan for you queries with and without hints and also paste the optimizer hints - show parameter optimizer.

How can I disable files from being shown in spotlight?

Hi All,
In my spotlight preferences I've enabled only Applications, Folders, and System Preferences. However, in almost all of my searches, many individual files are shown. These are usualy .java, .jar, or .html even.
To exacerbate the problem, spotlight seems to be looking inside the files when it searches/indexes. So I get many files that dont have my search terms in the title. Basically, the things I want are at the bottom, far below a bunch of files that I don't want to see.
Is there any way to filter these out permanently?

Found a solution. It is this. But Thomas is correct in assuming I am using it as an application launcher. This fix allows me to resume this activity as it was in Snow Leopard.

Bug? My events on the iPad iCal app aren't shown in the year view if they are more than two years in the future.

My events on the iPad iCal app aren't shown in the year view if they are more than two years in the future even though I can see them on the month, week and day view. Any suggestions on how to fix it? I've tried it all. I called the apple support and they checked on their iPads. They all did the same and they couldn't help me. They suggested trying this way. I'd like to be able to plan a few years ahead and the year view would make thing so easy!
Is this a bug?

Go to the Home screen and double click the Home button. That will reveal the row of recently used apps at the bottom of the screen. Tap and hold on the app in question until it wiggles and displays a minus sign. Tap the minus sign to actually quit the app. Then tap anywhere on the screen above that bottom row to return the screen to normal. Then restart the app and see if it works normally.
Then reboot your iPad. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider until the Apple logo appears. Let go of the buttons and let the iPad restart. See if that fixes your problem.

Hi,
I'm Galit from the QE team of VIN.
All the things that you've described are correct.
It is actually an edge case where the only VM, that the manual App can be managed from its Map view, was removed from the App.
The Manual App management is as designed, and may be changed in the future.
There are 2 ways to overcome this situation:
1.You can, as you stated, create another Manual App with similar name and remain with the "Zombie App".
2. To run a specific command that will remove the Zombie App from the DB.
Please note that option no. 2 involves using an API that we do not publish.
If you would like to use option no. 2 contact me in private and we will see about supplying the relevant commands to run in order to delete the "zombie" application.
Thanks,
Galit Gutman

Some fonts are not shown correctly in LabVIEW 2012

I found a bug related with fonts in LabVIEW2012 f3 KR.
- When I select NI7SEG in font selection dialog, right font is not shown in the example box.
- Draw text at point.vi shows same problem for some fonts while other fonts are working.
I reported it to Korean NI. As far as I know, this was not reported in previous versions and I couldn't find any related documents in Google.
So, here I would like to know whether it is related with only Korean version. Please let me know if English version is OK.
* OS: Windows 7 32bit KR

Just now, I installed LabVIEW 2012 f3 (32-bit, English) and checked for the issue. But the font(NI7SEG) was not shown properly in VI either.
- Both of Korea and English version of LabVIEW 2012 on Win 7 Korea OS shows wrong results. It is same on 64-bit OS.
- LabVIEW 2010 but on same PC shows correct fonts.
Is there a limit of number of fonts in LabVIEW? There are more than 100 fonts are shown in the "Selection Font" dialog and I can divide them into 3 groups by sequential order. I find that all fonts in the 3rd group are not applied correctly.
(1st group)
Arial Unicode MS...
Bookshelf Symbol 3....
Windings 3
(2nd group)
@Arial Unicode MS...
@Terminal
(3rd group)
Arial...
Consolas...
Courier...
Licida Console...
NI7SEG...
Verdana

Is the file size of a selected image shown on Adobe Bridge CC 2014? If so, where?

Is the file size of a selected image among the filter categories? Or anywhere else? I know I can find it in Photoshop, but that is cumbersome.

The file size is shown in the Metadata panel.
You can not filter on file size but you can sort by file size.

Hi,
Error 7 is when a router or the connection to the router is broken in some way.
Some devices have features such as Denial Of Service protection (DoS) that cut a particular Internet Port when it thinks too much data is coming (Presuming it is an attack.)
iChat 5 in Leopard is not capped by the System Preferences > Quicktime Streaming speed (which we used to suggest was set at 1.5Mbps)
It now sees your whole Connection speed and your Upload may be much faster than this.
Your Download is likely to be much faster. However iChat will tend to operate at the lower figure of your Upload.
DoS features are threshold based.
You may now be bumping in to this Threshold where you were not before.
SPI (Stateful packet Inspection) does a different job but has the same effect when it is overloaded by the speed of the data.
If you have either of these features, turn them Off (Disable them)

Adobe Muse (2014.3) "Add Web Font" Function Not Working As Expected - Newly Added Fonts Become Unavailable Though Shown

Hello.
This has also been posted in the Community: Adobe Muse Bugs forum.
I've been having some odd/irregular issues though they have now become fairly predictable in nature. The issue is in regards to Adobe Muse (2014.3) and the availability of web fonts provided through the applications "Add Web Fonts" feature. Once added they perform as expected but then become "unavailable." Full details below. I have been a Creative Cloud Complete subscriber for a number of years so am fairly familiar with the way in which the system works minus a few issues that have popped up now and then, this one included.
System Info:
Adobe Creative Cloud (Full Subscription): Version 1.9.1.474
Adobe Muse: Version 2014.3
OS X Yosemite: 10.10.2
Here is a recap of what has been taking place. I'll detail the bug as best I can.
1. Created new Adobe Muse project. Everything normal.
2. Chose to add a new font through the "Add Web Fonts" function within Muse. A note, my Creative Cloud App is running/open at all times (in file synch mode).
3. Chose new fonts using above. All seemed fine (see screenshots below).
4. Fonts also were indicated as being "Synched" within Creative Cloud (screenshot below).
5. As expected the two fonts were added to the list of available Web Fonts within Muse (first screenshot below - left). I added them successfully to my site. Well after a number of hours I went back to this same font selection menu within Muse and the fonts were still visible yet the sub-menu that one would expect showing various forms (i.e. Bold, Italic, etc) was not available. In a sense the font could not be chosen from the list even though the name is clearly visible (second screenshot below - right).
Have no idea what may have been wrong. Saved Muse project, closed and reopened - nothing changed. Created new project - fonts still "shown" in menu but can't be used. Did find a vague description using Google of similar problem (different application) which recommended closing Creative Cloud Desktop App and reopening as one possible solution. This DID WORK initially yet the problem, though corrected for a period of time (few hours at most), would reappear again where one would again see yet not be able to choose from the two Web Fonts. Went so far as to uninstalling the Creative Cloud Desktop application and reinstalling. Still have not solved the problem.
Any thoughts as to what this may be would be welcome. Restarting the CC app each and every time the fonts become unavailable is quite time consuming to my workflow.
Thanks!

Abhishek,
Thank you for the reply. Wanted to comment on a few things.
I reviewed the other post that you've referenced. Nothing unusual jumped out at me as something that I was not aware of. I'm running an older iMac that is in good working condition. 2.4 GHz Intel Core 2 Duo, 24" screen. I know this issue is fleeting, as I stated earlier typically can be corrected with a restart of the CC Desktop application (that I am always running at startup). I have not been able to determine that shutting down Muse corrects the issue. I would, at this time say it doesn't.
I did open InDesign and see if the fonts in question, Open Sans and Open Sans Condensed, were present and usable. They were. The fonts are shown as being synched in my CC Desktop app window (even if they are not "installed" in Muse). That is expected but it may be a bug in how Muse brings in a font from those that are already synched to your CC account. I don't know enough about how that works to comment.
And just to complicate matters, Muse seems to be working again, the fonts that is. I brought them back in and they are showing up in all locations (which there are actually three - see screen shots).
First is primary text menu dropdown (to right of orange "Text").
Second is if you click orange Text link. Another drop down menu appears.
And lastly, the Text Panel to right of screen.
I also wanted to add this extra bit of information, for what it is worth. When the issue arises and you do not get the sub-menu dropdown showing various styles of the font (italics, bold, etc.), one can use click on the missing font if you had used it previously and it is present in the "previously used font" list.
Cheers!

No cell seperator shown after adding rows to table

Hi All,
I'm trying to add rows for the user to click on to 'add new' similar to the contacts application. It works, but when the new row displays it has no separator. My code is inside the setEditing overridden method as shown...
- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
// call super first
[super setEditing:editing animated:animated];
// add/remove placeholder items
[self.tableView beginUpdates];
NSMutableArray *indexPaths = [[NSMutableArray alloc] init];
for (int g=0; g < editGroups.count; g++)
if ([[editGroups objectAtIndex:g] isArray])
// get the count of objects for this group
SEL propertySelector = NSSelectorFromString([[[[editGroups objectAtIndex:g] editFields] objectAtIndex:0] fieldName]);
[indexPaths addObject:[NSIndexPath indexPathForRow:[[editObject performSelector:propertySelector] count] inSection:g]];
if (editing)
// Show the placeholder rows
[self.tableView insertRowsAtIndexPaths:indexPaths withRowAnimation:UITableViewRowAnimationFade];
else
// Hide the placeholder rows.
[self.tableView deleteRowsAtIndexPaths:indexPaths withRowAnimation:UITableViewRowAnimationTop];
// send object did update message to delegate
[delegate didUpdateObject];
[self.tableView endUpdates];
Thanks
Ray

I just found the problem, and for anyone else out there with the same issue. I had to remove the [super setEditing:editing animated:animated] at the beginning of my method. My super is UITableViewController, and for some reason calling the super on this method causes the seperator lines to vanish.
Thanks All

Hi when i open my application folder, all the application is shown in trash folder. when i click the application it says this app is in trash first move it out. and when i try to open through finder go it says this file doesn't exist. can some1 plz help?

hi when i open my application folder, all the application is shown in trash folder. when i click the application it says this app is in trash first move it out. and when i try to open through finder> go it says this file doesn't exist. can some1 plz help? how can i put all my application through application folder?

Something really odd is going on. In your first screen shot, I noticed that the Applications folder does not have the proper icon displayed in the side bar. Also, in the title bar it lists it as Applications 08-59-29-909.
Not sure where it's picking up that odd name, unless it's because it's still truly within the Trash folder.
Try this. In the Finder > Preferences > General > turn on "Always open folders in a new window". (I have a feeling you have the default setting with this off).
Now, in Finder > Go > move down and open the Applications Folder from there. Now open the folder where you see all your applications that you show in your screen shot, select all, and move them to this true appliactions folder.
This is what you should properly seeing (but with different apps listed):
See how the Applications folder has the icon of the letter A shaped with a pencil, ruler & pen.

IPC/VC: Knowledgebase/KB of ECC is not shown in CRM

Hi,
we would like to use the Variant Configuration in CRM.
Today we are using already the IPC in a standalone environment with an external system (IPC 5.0, the external system is using the IPC in the Java environment of ERP). From the same ECC System we would like to download now the knowledge bases to reuse them in CRM 7.0. All knowledge bases and runtime environments are already available. When I download the object SCE (with certain filters), I can see all those entries in table COMM_CFGKB in CRM.
Anyhow, when checking the material in CRM (e.g. commpr01 or WebUI), no knowledge base is shown!
The table COMM_CFGKB has exactly the same entries as ECC (Active = T, KB Usage 10, KBOBJNAME and Version filled etc.), but anyhow it is not shown at all in CRM. As these knowledge bases are very huge, I have tested also a very small and easy one. This one is getting downloaded the same way and has the same entries in table COMM_CFGKB and it is also visible in commpr01.
So my assumption is that the other KBs are not 100% correct. When checking them in ECC (cu36) I get many warnings and errors. Anyhow, they were downloaded to CRM (but won`t be shown). Business says that these warnings/errors are OK and that the external system which uses the IPC in ECC is not having any problems.
Question: is there any chance of using a KB in CRM which has warning/errors when it was generated in ECC?
Is there any chance of manipulating the KB before it gets imported into CRM. I have found Note 1044682 which explains a BADI.
Which tables/fields do we have to manipulate so we are able to use the KB in CRM.
As mentioned: business is aware of those errors and excepts that there might be a crash in the IPC for certain combinations.
Thx
Guido

Hi Christophe,
OK, I think I understand your suggestion: you use the same IPC with your CRM as well as with the ECC system. So in CRM you just maintain the URL and a user in XCM to the "same" IPC. You mentioned that we need to download anyway the SCE. This is somehow logical as this is the base connected to CRM, but what is not clear to me is the fact, that if the SCE KB is used via ECC all SAP R/3 fields are available (like VBTYPE of the sales order where you have values like B or C). In CRM we use the same SCE KB but here these fields are not availble as the sales order transaction customizing in CRM does not contain such a field. Where is the logical link between the values which are available in IPC and the SCE?
Thx
Guido

Restrict filter values that are shown in the selection screen

Hi Experts
1) Is it possible to restrict the filter values that are shown in the selection screen in BEx web? When a user are asked to enter a material number and uses the selection button in BEx web, he should only see material numbers for one specific plant. How is this done?
2) Is it possible to remove the selection button for å characteristic filter in the selection screen in BEx web? The selection button I am talking about is the button to the right of where you enter the filter value (two white papers on top of each other). If there is no solution for question 1 we have to go for question 2 solution.
We are using BI 04s, SP 09.
Kind regards
Erik

Hi Erik,
It seems that you would like the user to see value for 1 single plant. If the Plant Value is fixed then you can use this value in the Query and hardcode it.> in the query go to the Plant Chrac and keep a constant value of the Plant.
How ever if you need this value to be dynamic then use a variable for customer exit and populate this value using ABAP.
Regards,
Jasprit

Voice memos sync not shown in iTunes

I am trying to sync my voice memos to iTunes a couple of times. They are not shown. I haven't updated my iPhone 5s to the latest software yet. It's still running iOS 7; my iTunes was updated though. Does anyone have a solution for this?
Thank you!!!

You need to open iTunes on your computer. Then select music library from the left-hand. Then in the search window on the top right of the screen type in voice memo . The voice memo should now appear in the list is available music in the middle of the iTunes screen
