Limit on the number of partitions a table can have

Hi,
It's been quite some time I'm thinking of a simple and the best solution to a performance issue in my application. Benefiting out of partitioning the table seems a simplest approach; it involves very minimal changes to my application code and in addition, it keeps the overall application logic 100% intact. However, at times, the number of partitions required can grow to as large as 500 thousand. I know of another application implementing as many as 50 thousand partitions for one of its tables. I'm wondering if Oracle recommends or poses any limit to a number of partitions the table can have. How does that limit, if it exists, vary if each of my table partition holds only a small amount of data; say, not more than 2 thousand records each of 1 KB size. What are the important considerations that one needs to keep in mind while creating the huge number of partitions for a table?
Any inputs on this would be a great help.
Thanks,
Aniruddh
ps: Consider Oracle releases 10g onwards.

I doubt if you are using partitioning for the right causes. Please explain how is your data structured and why you need to create so many partitions..?
when creating partition, you need to consider..
a) why you need to partition?
b) how is your data structured
c) how your data is indexed.
d) What kind of queries would you firing on this table to get the data. Will they use the partition key ?
Thanks,
Rajesh.

Is there a limit to the number of video files that can be included in a captivate 6 project?

I have a project that includes 15 slide video files. When I preview the project in html or publish it, I get a green rectangle where the video should be on about the 10th slide. Even if I rearrange the order of the slides, always on about the 10th one I get a green rectangle where the video should be. Is there a limit to the number of slide videos you can have in a project?

Craig,
It was image.cpp line 2770. I am told (by another person in the company that has seen this) that it has been seen on several machines, always PXI controllers, but not on all PXI controllers. I am told that it is not always image.cpp that reports the error, but for me it was always the same line of code identified by the error message. I did not have a chance to do any experimenting to find a particular threshold number of mnu files. I may be able to find error logs. I currently sent the controller to our IT department, doing a windows XP repair, just in case there was something corrupted in the system itself.
The error was reproducible. This installation at one time must have included real-time / FPGA, because on the opening screen I ge the drop-down ring for selecting a target. If I click on this drop down ring, I get the crash on line 2770, every time. If, instead I open an empty new VI, I am able to switch to the block diagram by selecting the window directly with the mouse, but if I try to pull down on the "window" menu to do "show block diagram", I get the crash on line 2770, every time. Because the user-defined mnu files are now deleted, I would have to create them again, or find a way to reinstall them, to reproduce the error at this point.

How to set a limit on the number of processes a session can start?

I have an Oracle db version 10.2.0.4 running on Solaris 10. My parallel_max_servers parameter is set to 650 and the processes parameter is set to 700. But I don see one session that is spawning 129 processes and another one that is spwaning 65 processes. Is there a way to limit the number of processes that a session can spawn?

check processes
$ ps -ef | grep $ORACLE_SID|wc -l
SQL> select * from v$resource_limit where resource_name ='processes';
My parallel_max_servers parameter is set to 650 and the processes parameter is set to 700.
PARALLEL_MAX_SERVERS
specifies the maximum number of parallel execution processes and parallel recovery processes for an instance. As demand increases, Oracle increases the number of processes from the number created at instance startup up to this value.
Do you use query with parallel?
example:
-> create table xxx PARALLEL (degree 5)
-> select /*+ PARALLEL
if you don't use parallel on execution processes... so, your processes not increase ;)
By the way your db have limited proceses= 700 (Dedicated Server Processes)

Is there a limit to the number of mails that Mail can import?

I'm importing from the last Time Machine backup of my MacBook Pro to a new iMac. The import gets stuck at 72k so I can't set up mail. I know it's nuts to have 100k of messages and I'll be doing something about that, but for now I need to get Mail working on the iMac. Any ideas?

No, but there are sometimes problems with importing the IE favorites directly.
If you have problems with importing the IE Favorites in Firefox then export the Favorites in IE to an HTML file and import that file in the Firefox Bookmarks Manager.<br />
That way you also preserve any sorting that you may have done in IE with the Favorites.
* Export the favorites in IE to an HTML file (bookmarks.html): File > Import and Export
* Import the HTML file in Firefox: Bookmarks > Show All Bookmarks > Import & Backup > Import HTML: From File
See "Import from another browser" and "Import from file":

Can someone please tell me if there is a limit to the number of Collections that one can create in iBooks on iPad 2?

Currently, I have 15 created and whenever I go to create another, I get a blank (black) screen and it then goes back to the home screen without letting me create another Collection category.
Any help is appreciated...thank you!

I don't seem to have that problem. Make sure iBooks is up to date. If it is, then try force closing the app and restarting it by double taping the home button, holding the iBooks apps until the red "-" appears. hit the "-", then close multitasking by hitting the home button or touching anyplace on the screen about the multitasking bar. If that doesn't resolve the problem, try delete and reinstall iBooks. If that fails, try hard resetting your iPad by holding down both the home and power buttons until it restarts.

Is there a limit to the number of apps that can be Hidden from view in Family Sharing?

I've just set up a Family Share and have issued invitations to a couple of family members.
I'm trying to take full advantage of the "Hide" feature that's available in the Purchased list in the App Store app, mostly to hide really old apps that I haven't used since the beginning of time. These apps have been long gone from any of my iOS devices, and it has always bugged me that they still appeared in my Purchased list. It's pretty cool that Family Sharing allows people to hide some of their app purchases from others in the group, as this also allows folks to hide apps that they also don't want to see in our own lists.
The first couple of dozen apps that I decided to hide stayed hidden. However: now, no matter what I try, I can't hide any more apps. I swipe on an app to reveal the Hide button; tap the button; the app disappears from the list; I go to another screen in the app; I return to my Purchased list: and the most recent Hidden apps are still listed.
This is driving me nuts. I'm wondering if Apple has imposed a limit on the number of apps that anyone can hide; or if there's something I can do to force a hidden app to stay hidden.
Advice will be gratefully accepted.

Not a bad suggestion, but it does not explain why an app refuses to REMAIN hidden on my iPhone -- as I explained in my first post:
> I swipe on an app to reveal the Hide button; tap the button; the app disappears from the list;
> I go to another screen in the app; I return to my Purchased list: and the most recent Hidden
> apps are still listed.
Given the clunkiness and general unreliability of iCloud - which rarely "just works" - it doesn't surprise me that hiding an app on one device doesn't mean the same app will be hidden immediately on other devices logged into the same account. I've learned to be patient and wait hours for changes to anything synced via iCloud to be reflected on other devices in the sync loop. But again, this in now way explains why apps were not staying hidden on the device that was used to hide them.
I've finally managed to hide all the apps I wanted hidden, after many hours of waiting and multiple attempts at hiding. I am in no way confident that these apps are going to REMAIN hidden permanently, or until I choose to unhide some of them; only time will tell if iCloud decides to behave and accept my series of "Hide this app" commands to be honoured permanently!

Is there a limitation to the number of calendars that iCal can manage?

My wife and I share calendars. Recently she found that one of my calendars was not showing up on her iMac and any dates or appointments were automatically sent to Notifications. However, all of my calendars and hers as well show up on her iPhone and iPad. With that we took her iMac to a Genius Bar. The tech after trying many things determined that because the age of her iMac (a 24", dual core) was limiting iCal to 10 calendars. I find this incredible. I can't image that this could be a hardware problem. She and both are running under Mountain Lion. Has anyone ever heard of this issue?

Is there a recommended limit on the number of custom sections and the cells per table so that there are no performance issues with the UI?

Is there a recommended limit on the number of custom sections and the cells per table so that there are no performance issues with the UI?

Thanks Kelly,
The answers would be the following:
1200 cells per custom section (NEW COUNT), and up to 30 custom sections per spec.
Assuming all will be populated, and this would apply to all final material specs in the system which could be ~25% of all material specs.
The cells will be numeric, free text, drop downs, and some calculated numeric.
Are we reaching the limits for UI performance?
Thanks

Is there a limit on the number of Key Lookups against a table in a mapping

I'm using OWB 11.1 and have a mapping with 15 Key Lookups against the one table. When I Validate the mapping it objects to a Key Lookup not being connected, even thuogh in the mapping all the Key Lookups have been renamed to their relevant fields?
Is there a limit to the number of key lookups against the one table?

Thanks for the replys.
I'm getting a validation error, so can't run the mapping. Error VLD-1108: Operator Key_LOOKUP is not properly connected.
The issue is solved, after checking each of the Key_Lookups, one was not connected to an output. The error occurs if an output field isn't used (connected to) a table or other operator.

Limit to the number of values I can specify in a query

Hi,
I want to select a certain number of rows from a table in my Azure Table Storage by specifying the PartitionKey and RowKey. Say, I have a list of 500 PartitionKey and RowKey pairs that I need to read from my table. Can I specify these 500 values in my query?
I have a feeling that I'll have to come up with a composite key as my partition key so that I don't have to specify so many PartitionKey/RowKey values but I want to first make sure that there's a limit to the number of values I can specify in a query.
Thanks, Sam
