• Inaccurate statistics calculated by the task of automatic statistics collection

  Hello
  
  I have a table with about 300,000 sets and I manually collected statistics for the table and its index with the command: "EXEC DBMS_STATS.gather_table_stats ('SCOTT', 'Table_test');" Both indices of the table statistics were accurate and the execution of SQL statements were also very powerful. Then, during the night Enterprise Manager recalculated statistics again, but the results were far from exact:
  
  OWNER: SCOTT
  INDEX_NAME: I_TEST_INDEX
  INDEX_TYPE: NORMAL
  TABLE_OWNER: SCOTT
  TABLE_NAME: TEST_TABLE
  TABLE_TYPE: TABLE

  The new statistics report that there are only 141 separate in the table key although there are actually 300 000. The result is that SQL statements executing degrades considerably. Does anyone know why the statistics have become so inaccurate? I'm on 10.2.0.1.0.
  
  Kind regards

  The only thing I'm not sure of is if I should include the statistics calculation step in the batch (this is a PL/SQL procedure) - I mean, it's a mixture of normal practices code that calculates statistics with business logic code?

  Swear,

  I think Justin has responded to this already pretty well, it is quite common in environments of warehouses of data or any other leads batch environments. You must be precise (or let's say representative) statistics if you want the CBO to do a good job.

  BTW, do you know if the collection of statistics on an Index organized table is somewhat different that gather on heap-organized tables?

  No, there is no difference. DBMS_STATS (and even surprisingly ANALYZE) know IOT and collect 'table', column and potential segments of infinity and the (mandatory) primary key index (representing the IOT) even if you do not specify a "cascade-online true" in the call DBMS_STATS.

• Why can I not see my rings of friends activity in the application of the activity

  MY girlfriend and I have updated our watches to OS3 and our phones to ios 10.  I want to be able to share our business segments while I travel.  We set up the sharing in the application of the activity on our two phones properly, she can see my activity sounds, as well as its own however on my phone I can only see my rings.  Her rings all show 0...  She shares his activity with a colleague and she could see her too but he did not see his.

  The strange only that we noticed, it was a trait on his 'me' page in the shared activity section which said "you can also share your activity from another device signed your iCloud account. I say strange because it shows a single associated with his account and it is the only watch shown in the list of devices.

  So far I have puzzled friends Apple local Store, and I thought I would do it because both operatlong systems are so new, but to try here and e s if everyone had seen this problem.

  Thanks for reading,

  Hi funkypickl,

  The application of activity is a great way to share your progress with friends and family! There are a few reasons why you are unable to see the activity and progress of your friend. It may be quite possible that activity can be deliberately hidden from your view. Or you can get an invitation that you have not agreed to your girlfriend to view activity pending. Finally, with an internet connection or stable data is required for updates and progress of the activity. Please take a look at the link below for some tips that should solve your problem.

  Share your activity with your Apple Watch

  Special attention to what follows below is in the article above
  
  

  To check waiting for calls,

  Open the application of activity, tap the sharing tab, and then click Sharing. Once your friends accept the invitation, they will appear in the section sharing of enforcement activity on your iPhone.

  Stop sharing or hide your progress

  To stop sharing of activity:
  Open the application of activity on your iPhone.
  Tap sharing, your friend.
  Press to delete a friend. If you do that, they can't see your activity, and you can't see their activity. To begin sharing again, send your friend a new invitation.
  To hide your activity:
  Open the application of activity on your iPhone.
  Tap sharing, tap the friend you want to hide your activity.
  Tap hide my activity. You can still see your friends ' activity, but they do not see your activity.
  To start sharing again, click Show my activity.

  Get help with sharing activity

  Activity sharing requires iOS 10 and watch OS 3. If more than one Apple Watch associated with your iPhone, the sharing tab appear not in the activity until you update all your watches to watch OS 3.
  If you are unable to add a friend, make sure you have a Apple Watch and that you have not added the maximum number of friends. You can add up to 25 friends.
  If your iPhone can connect to the Internet and you are connected to iCloud, you can get the updates relating to the activities of your friends every day. If your iPhone can not connect for several days, or you disconnect from iCloud, you may see missing days.

  Please use the Apple Support communities to post your question. This information should have you look at progress of the activity of your friend in no time!

• Is it possible to have a common accessible file location for the main application in the sandbox and its extension app plugin

  I'm trying to launch an app on the app store for mac. The bundle of the main application and everything inside it is on sandbox.

  The main application Bundle identifier is com.xxx.core.app . The identifier for the internal Plugin Finder Extension application Bundle is com.xxx.core.app.extensions .

  Now the problem is the extension inner finder is also available in sand and trying to read a file written by the main application.

  The main application writes the file location depending on mac OS X, for example temp/var/folder/jv11743453495593/T/com.xxx.core.app

  But the internal Plugins try to read/var/folder/jv11743453495593/T/com.xxx.core.app/extensions

  Because of the different bundle identifiers, they have different containers.

  Can someone let me know how to limit the same application and its plugins to the same folder location. Does perform a work around for this problem.

  Hello yuktikapahwa,

  See the Sandbox Apple Guide under the ApplicationDirectory group container

  You must create a group that your container can access. I'm not 100% certain that this will work with extensions of Finder, but it seems the most logical place to start.

  PowerPC applications have not been supported for many years now since, OS X 10.7.x, you need to look for an alternative to this app or contact the developers of Spotify to see if they have a version for El Capitan 10.11.x
