How can I get a count of objects in the near cache? (Extend client)

Hi,
I'm trying to figure out how to get the count of objects in my near cache (from c++ client). Knowing the size of the near cache is a key factor when optimizing configurations for performance.
However if I call size() on the cache handle I get the count of objects in the cache (ie the cluster). How can I get a count of objects in the near cache?
Thanks

H Rich,
It may not be ideal, but I think you may be able to infer the size by using the HeapAnalyzer (http://download.oracle.com/docs/cd/E15357_01/coh.360/e15728/classcoherence_1_1lang_1_1_heap_analyzer.html) facility, specifically the "class" based HeapAnalyzer. Its Snapshot representation http://download.oracle.com/docs/cd/E15357_01/coh.360/e15728/classcoherence_1_1lang_1_1_class_based_heap_analyzer_1_1_snapshot.html provides a mapping between class name and ClassStats (http://download.oracle.com/docs/cd/E15357_01/coh.360/e15728/classcoherence_1_1lang_1_1_class_based_heap_analyzer_1_1_class_stats.html) which provides information on how many instances of a given class type are in memory. Note the reported counts are process wide but if your key or value type are distinct you may be able to infer your answer. I realize this is rather complex, my only other suggestion would be to just make some guesses on size and see how they effect performance.

How can I get record count with a query?

In Client/Server pplication,the client send a query to server.
How can server get record count by oracle call interface?
Is it need execute "select count(*) from ...."?

Yes.
Either that or increment a counter for each record fetched and
loop round until you hit the last record.
The first method would be more efficient on large datasets.

How do you get word count to print at the end of a document in Pages?

How do you get word count to print at the end of a document in Pages?

Pages v5 does not provide a user assignable word count variable. With some AppleScript, and a paste operation from the clipboard, you can have locale punctuated word count in this format: 7,803 — anywhere in your document. The following AppleScript works with Pages '09 v4.3 through Pages v5.5.2 on Yosemite.
I would suggest that you copy paste the following AppleScript into your [Apple] Script Editor and save it (suggestion) wordcnt.applescript. Then, follow this with an option+Save As… and this time set the File format to Script Bundle, or Application with hidden extension — saved to your Desktop. Provided you have a Pages document open, you are then a double-click from the ability to paste your current word count into Pages.
Note: If you have Pages word count display enabled, it will automatically count your pasted value as another word which initially may deceive on true word count at the time the script was run.
AppleScript
--- copy below this line ---
property locale : "en_US.UTF-8" -- In Terminal, use the locale command to see yours
if not ApplicationIsRunning("Pages") then
     display dialog "Pages must be running to use this utility."
     return quit
end if
tell application "Pages"
    tell body text of front document
        set wordCnt to count words
        -- Don't want punctuated numbers? Remove the single quote from printf format
        set the clipboard to (do shell script "export LC_ALL=" & locale & "; printf \"%'d\" " & wordCnt)
    end tell
end tell
on ApplicationIsRunning(appName)
     tell application "System Events" to set appNameIsRunning to exists (processes where name is appName)
     return appNameIsRunning
end ApplicationIsRunning

How can I get rid of multiple pictures at the same time?

how can I get rid of multiple pictures at the same time?

Adobe Bridge, lightroom and your file browser (windows explorer or Mac Finder) can select multiple pictures at once and then delete. If you are looking for more than that for information, you will need to be more specific at what your doing, what OS you have, and version of software your using. If necessary post screen shots so we can see what your doing. The more information we have the more detailed of an explaination can can give back to you.

How can I get my POP account showing in the inbox it's supposed to show in?

Hi-Until a couple of weeks ago all mail received from my IMAP and POP accounts would show up in the correct mailboxes in my Mail inbox list. (Only problem then was that sent mail would never show up in the sent mail folder--always stayed in the inbox.)
Now a new problem has happened----unless I go directly to my charter cable account (P0P account) to retrieve any mail sent to that particular address, the mail goes unnoticed by Mail on my MAC and nothing shows up in the inbox. But--- If I do a test to myself , sending an email to the POP address from my IMAP account from my MAcMAil, my IMAP account will show the email in the inbox of the IMAP account I sent it from as if I'd mailed it to that account. How can I get my POP account showing in the Inbox? And, any suggestions for a fix to getting the "sent" mail to show in the "sent" folder would also be appreciated.
Thanks!

Thanks, just so I know we are talking about the same items please let me know - When you say "run Prokit" do you mean downloaded? Which I did. I dont have Prokit 4.0.1 if you are referring to that, do I need this first? Please explain what application name I am looking for if other than Prokit which is sitting in my "download folder" do I need to manually put it into the apps folder? Sorry if the questions are layman but this area is not a very strong point for me. Thanks for your help so far.

I use my iPad to get the address book backed up by iCloud from my iPhone. However, I cannot see the recent new contacts from my iPad. Is there anyway to check the iCloud server to see if my address book backup from my iPhone is still there?

iCloud storage is not allocated by device. iCloud storage is allocated to your iCloud AppleID. You get 5GB of iCloud storage.

I found out that I have some lost contacts on my iphone 5s, they dont appear when I search but if the contact calls me I see their name. How can I get those contacts to be on the list?

You could check settings > mail contacts and calandars and see if there are any accounts (like icloud gmail yahoo) listed and if they have contacts on. Its possible if contacts were synced to one of these accounts that turning them back on will recover the missing contacts.

You will need to connect your iPad to your computer's iTunes and do File > Devices > Transfer Purchases to copy them over to your computer (that will copy PDFs and epubs that are in the iBooks app, not just actual ibooks), and you can then sync them to your iPhone. Or you might be able to open each PDF in iBooks on your iPad and use the share icon to email them to yourself and then use 'open in' in the Mail app on your iPhone to copy them to its iBooks app (if the PDF is protected then you may not get the email option via the share icon).
The Settings > iBooks > Sync Collections setting doesn't copy items between devices, it just means that it a bookor PDF is on both devices and you move it into a collection on one device then it will be moved into the same collection on the other device

How can I get my iphone to stop losing the signal?

How can I get my iphone to stop losing the signal?

Thanks for the tip. If only I could find somewhere where I did not lose the signal.
I am based in the United Kingdom. The carrier is Orange.
I lose the signal inside buildings and outside of buildings. It happens at work and at home. It happens in Centarl London in the open air and inside. It happens in small towns.. It happens in the countryside. It happens in motor cars. It happens in airports. It happens when the battery is fully charged, when it is half charged and when it's low on charge. It happens using the phone, when reading messages and when using the internet.
Hope this helps.
