CcBPM, Async Messages and database update performance

We have several business processes defined and running in XI 3.0. Some are being invoked as web services.
Our performance/scalability is extremely poor. We believe the problem is the database, which apparently is being updated at a phenomenal rate. The database disk I/O is exceptionally high, and has been tracked to writing to the database container/table files and tranaction logs. The database has been carefully tuned, and we are rushing to migrate the db to a higher capacity machine.
It would seem, based on documentation, that the database updates are a result of the asynch message interfaces we are using through the business processes.
The first question is are we correct in the above statement?
The second question is are the db updates being done under a transactional scope, if so what is the isolation level of the update, and can we change the isolation level?
Third question, if the updates are due to the asynch message interfaces, can we use synch message interfaces and reduce the database work? If so, how?
Finally,

I don't think you'll find a documented general number of application variables you can have on a single server. But I think you could get away with 400 variables without any trouble.
Where you might run into trouble, though, is when you have multiple concurrent requests trying to read and change these values. You'll have to ensure that you single-thread write access to these variables using CFLOCK.

I have found other threads with this problem. The problem is that you are using your iTunes account on another user at the same time you want to update software. Just close iTunes from that user. See > https://discussions.apple.com/thread/4577180?start=0&tstart=0

NextnPrevious pages and database update

Hi Folks,
Am hoping someone can point me in the right direction on figuring this out...
I have 120 individuals in the database with related fields. Instead of displaying 120 rows when I pull the data from the database, I've built Next/Previous pages for displaying them 30 to a page.
Here's the thing: This is an admin section, pulling names and IDs and fields (text, radio buttons, dropdowns, etc.) for data entry, or rather, database update.
So, after displaying 30 on the page you have a link on the bottom of the page to display the next 30. This page refreshes itself...
Either I have to cache the update info from each page and put a submit button for updating on the last page or, submit each page (30 at a time) until each succeeding page is done, one at a time. See what I'm getting at? I think I'd rather be able to submit 30 at a time instead of trying to cache all the data as you move from page to page but am having a hard time trying to figure this out.
I'm not sure what is best or just how to do the database insert/update since the Next/Previous CF code depends on the same page refreshing itself each time for the next pages.
Also, the first page of this 'group of NextPrevious pages' is dependant on it's previous page of "select school", so that the first NextPrevious page (and following ones) displays the individuals from that particular school - 30 at a time.
Can anyone point me in the right direction on this kind of database insert/update when used in conjunction with Next/Previous page links?
Thanks!

Thank ya'll for the ideas...
You know, before posting this I googled and googled and was surprised to find hardly anything addressing this. I would have thought it would be a fairly common way to perform edits on a large number of table rows - when you only want to display, say, 30 per page instead of 1200 records on one web page for admin edits.
With Meensi's and Furnis' suggestions and, a bit more thought... I kept thinking... It's pretty much like a shopping cart - holding a variable(s) from page to page. I know there's many ways to do this but the problem here lies in the page refresh holding variables with each refresh.
Seems logical to update All edits at one time - submit the form on the last page. I'm wondering, say as in the case you may have 1200 NextPrevious pages (!) - You'd want the user to do it in bits, page per page.
Since a clicked link clears session variables... maybe make the page refresh link (Next Page) a submit button and, on refresh, submit just "this particular page variables" and at the same time, the refresh loads the Next Page variables - updating the database in increments and display the next batch to edit.(?)
Does this make sense? I do want to make this a 'no-brainer' for the user - an admin section being most intuative is foremost to me...
The following is (stripped down) code I'm using to run the NextPrevious pages. I think maybe if I add the database insert somewhere in the code at the top of the page, coming from a form submit button that refreshes the page at the same time - maybe this would be the way to do it.
I'm not sure if there will be a problem wrapping the <form></form> around just the current variables on This Page. Maybe not. I think I may experiment with this, though...
Thank for your input on this.
Does seem like something like this, updates within NextPrevious pages would be a common practice and an easy fix doesn't it?

<b> Properties of an Async message?</b>
An async message is only 1 way communicaton it's like you are giving information but not expecting the reply for next information to give.
<b>Inbound XI message has problem, where do you look for
solution?</b>
you will look into SXMB_MONI for any information regarding both the outbound and inbound messages.
<b>Describe XI message format?</b>
XI Messages are in the SOAP format:

Nokia Messagging and scribble updates only avialab...

I've have and 5230 rm-588 hispania black-black with the latest firmware (50.0.001), and when I look for updates via phone itself their show me that are updates avialable for messaging and scribble, but if I look for updates in OVI Suite they says that isn't any update avialable.

yes...i also got a update
Main menu, new web browser, ovi store, ovi music - all has got kinetic scrolling.
Now you won't get low memory errors because web browser has greately improved. These is no tabbed browsing until you click on a pop-up link but the kinetic scrolling is now good and the full screen mode is good, now you get a information bar when load any new page which is very helpful. It goes away when the loading is done. It goes to full screen every 3-4 seconds you leave it alone.
Flash player has improved(for .flv files) now you can fw or rev videos.
Still there are some problems like when you go to settings>themes>homescreen and select your theme as contacts bar and then you deselect contacts bar (the one present in the home screen option) , the contacts bar is still present at the home screen. But if you again select it, it'll get disappeared from the home screen.
Still the phone hangs but now it gets normal after you leave it for 20-25 seconds. Now you dont need to remove the battery to restart.
The viruses I observed before the update were not working which is really good.

Scan error message and unable to perform system restore.

During a virus scan with Avira I get the following message and the scan cannot be completed; "The exception unknown software exception (0xc0000409) occurred in the application at location 0x0042ff93. Click OK to terminate the program." This has only just happened with no problems in the past. I have not loaded anything since the last scan and there are no problems with the pc except that I also tried to restore the system back to a date before this occurred however it fails.

Have you tried uninstalling and reinstalling Avira?
Also run Memtest to ensure the RAM is not corrupting the files.
1) Go to http://www.memtest.org/#downiso and download the "Pre-Compiled Bootable ISO (.zip)"
2) Open the ZIP file and extract the ISO file to a temporary folder.
3) Burn the ISO to a blank CD using a Disc-To-Image project in your CD/DVD burning software (dont use a normal Data Project).
4) Insert the Memtest CD into your laptop and turn it on, press F12 to launch the boot menu, and select "CD".

Annoying update messages and forced updates

Dear Skype,
I have been using your application for more than a decade now, and today I decided to untick the box "Start Skype at computer startup". I don't delete skype for now, but I am close to permanently remove it.
I have had it with your annoying forced updates.
So long

Hi, Kormendi_adam.
I'm sorry to see your intent to leave Skype.
Skype dynamically updates to better the Skype network and some updates include a major change that require you to update. This could be anything from a major compatibility change or even a critical bug patch. 9 out of 10, the intent of the Skype development team isn't to push out a new flashy design to be forced into your acceptance, but rather to make improvements that the majority of the userbase would benefit from.
That's not to say that you will and must enjoy it. That's why we have the Skype community. I'm glad you put your opinion out there. I'm really sorry that you cannot use an older version of the Skype client. I do hope that you will take the time to learn, use and enjoy the latest version of Skype. It has made great strides over time and has become quite the choice in Internet communications and it would be greatly missing a piece if you left.
And please, if you have any question about Skype or have any bright ideas, please don't hesitate to post them on the Skype community. We're here to help!
P.S.: Did you disable Automatic Updates as an Administrator? You mentioned before that you disabled startup upon login only.

Hi all,
I am having Query about BDC Error Session. If I see the log of Error Session, then few Transactions are processed and few are in incorrect status.
Those transaction, which are processed, Does it mean that it has updates the database successfully or Error Session will never update the Database?

API and Database updates

Greetings!
I've searched the archives for the forum and I can't find anything relating to my issue, so hopefully someone will have an idea of how I can get started on a new project.
I have an SQL database that contains a row for each hour of each day. Every row contains a date (obviously for every one day there are 24 rows), an hour interval (1:00pm), the day of the month, the day of the week (Saturday), the Meridian, the Military time conversion (13:00), the week of the year, etc. This database is used for reporting purposes and it runs out of rows as of next week. I have been tasked with adding enough rows to last us another 2 years, which is about 17,000 rows.
My colleague mentioned that I might be able to find what I need in the API and then write a little Java program that interfaces with my database to update the rows. Being completely new, I'm a little unsure as to how to go about researching this.
I did poke in the API and I found the DateFormat class in the java.text package. It seems to have just about everything I need except for the military conversion.
Does anyone have any thoughts on how I could use this class to write out these future rows to the database? One thing I should mention is that each row has a unique row-identifier that increments sequentially.
If I have been unclear, please let me know and I will try to clarify. Any help or a nudge in the right direction would be greatly appreciated!
Thank you!

Java can acces SQL databases through JDBC. Here is a
JDBC tutorial that can help you get started:
http://java.sun.com/docs/books/tutorial/jdbc/index.htm
i have looked at this tutorial yet there is a problem that i cant really deal with:-
* am using net beans (windows xp), mysql server, and j/connector driver.
* in net beans, in the RealTime Tab i can access my database in MySQL, but every time i write my code (in java)so i can connect with it and manipulate its tell me :
SQLException: No suitable driver
SQLState: 08001
VendorError: 0
my question is why can i access my database through 'Databases' in 'RealTime' tab, and not be able to make a simple connection with it when i run a simple code like this:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class LoadDriverP {
public static void main(String[] args) {
try {
Class.forName("com.mysql.jdbc.Driver");
} catch (Exception ex) {
// handle the error
try {
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/world"," user", "pass");
// Do something with the Connection
} catch (SQLException ex) {
// handle any errors
System.out.println("SQLException: " + ex.getMessage());
System.out.println("SQLState: " + ex.getSQLState());
System.out.println("VendorError: " + ex.getErrorCode());
could it be anything to do with CLASSPATH if it is please tell me what is this CLASSPATH and how can i change it.
any help would be greatly apreaciated.

Workflow..auto mailers and database updates

Hi,
My requirement is as follows...
i have a report in which i have a register link. On click of the link i need to show a form in which i have to populate a multiple select box which will be populated by quering the DB with the current user ID. Once the list is populated, the user selects some of the values and clicks a button. Thereafter i need to insert the details in the DB for each and every entry selected in the list. The details to be populated need to fetched from another table in the Db. Also on every insert i need to send mailers to the corresponding entries...
Please give me an idea as to how should i go about doing this.
Few of my main concerns are.
1. How do i use the current user id to fetch the details from the Db.
2. How do i show a multiple select text box.
3. What component do i use...like form or report..or anything else....
4. how do i insert entries in the Db for every value selected in the select box. Also the details to be inserted are to be fetched from the Db itself in addition to some other parameters like, current user id, sysdate,etc...
Also please let me know if there is any reading material for the same.

There was a bug in checkURLFile. This is fixed with higher versions.

How Async messages can be resend/restarted? Please help!

Hi Experts,
I have read that Async messages are persistent that is XI stores Async messages in database. That means Async messages can be resend or restarted on the event of a failure.
1. Will the XI server resend/restart async messages automatically or we have to restart manually from SXMB_MONI transaction? Is there any other transaction from where Async messages can be resend or restarted?
2. Is there any setup needed to make Async messages restartable? Where do we do this? Can this be done for Sync messages?
Please help me.
Thanks
Gopal

Messages and Calendar each on separate accounts?

Before I install Mountain Lion on my elderly father's MBAir, I'd like to know if I can set this up:
-- Have his Messages work with his Apple ID / email address, so he gets and sends his own messages.
-- Have his Calendar be linked to my Apple ID (my iCloud) so I can remotely maintain his calendar for him.
-- Have his Messages include his AIM identity so we can do remote Screen Sharing within Messages (incredibly handy for fixing his problems, without long car trips)
I'm pretty sure the first and last ones are a given, but I'm not sure if I can have separate logins for Messages and iCloud.

Update -- I tried my original proposal. It works. That is, On my dad's MBAir I used his AIM ID and his Apple ID as two accounts on Messages. Thus we can Screen Share for remote problem solving and he can do messaging. And I used my Apple ID for iCloud on his MBAir, allowing me to change his calendar for him.
Beware -- in the process I accidentally had both his and my iCloud accounts running on his machine, and mistakenly merged Contact lists. It was a bear to undo, and required dumping a VCard file of my contacts into my iCloud.com Contact list to fix it. I may not have solved it the most efficient way, but it worked.

My iMessages don't work since updating. It says the Messages database is being upgraded, please wait while it finishes or Quit Messages and relaunch it later. How do I get them working again?

My iMessages don't work since updating. It says the Messages database is being upgraded, please wait while it finishes or Quit Messages and relaunch it later. How do I get them working again?

Back up all data.
Quit Messages if it’s running. Force quit if necessary. Relaunch it and test after each of the following steps. If the problem isn't resolved, quit again and go on to the next step.
Step 1
Make sure you know the ID and password you use with iMessage. Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Select the login keychain from the list on the left side of the Keychain Access window. If your default keychain has a different name, select that.
If the lock icon in the top left corner of the window shows that the keychain is locked, click to unlock it. You'll be prompted for the keychain password, which is the same as your login password, unless you've changed it.
Right-click or control-click the login entry in the list. From the menu that pops up, select
          Change Settings for Keychain "login"
In the sheet that opens, uncheck both boxes, if not already unchecked.
From the menu bar, select
          Keychain Access ▹ Preferences ▹ First Aid
If the box marked
          Keep login keychain unlocked
is not checked, check it.
Select
          Keychain Access ▹ Keychain First Aid
from the menu bar and repair the keychain.
From the Category list in the lower left corner of the window, select My Certificates. Look carefully at the list of certificates in the right side of the window. If any of them is marked with a red "X" as expired or invalid, delete it. Also delete all items with "iMessage" or "com.apple.idms" in the name, whether valid or not.
From the menu bar, select
          Keychain Access ▹ Preferences... ▹ Certificates
There are three menus in the window. Change the selection in the top two to Best attempt, and in the bottom one to CRL.
Log out and log back in.
Step 2
Hold down the option key and select
          Go ▹ Library
from the Finder menu bar. Move the following items from the Library folder to the Trash (some may not exist):
          Containers/com.apple.corerecents.recentsd
          Caches/com.apple.Messages
          Caches/com.apple.imfoundation.IMRemoteURLConnectionAgent
          Containers/com.apple.iChat
          Containers/com.apple.soagent
          IdentityServices
Leave the Library folder open. Log out and log back in.
Step 3
Go back to the Finder and move the following item from the open Library folder to the Desktop:
          Messages
Note: you are not moving the Messages application. You’re moving a folder named “Messages.”
If Messages now works, delete the Messages folder on the Desktop. Otherwise, quit Messages again. Put back the folder you moved, overwriting the newer one that may have been created in its place.
Step 4
In the Preferences subfolder, there may be several files having names that begin with any of the following strings:
          com.apple.iChat
          com.apple.ids
          com.apple.imdsmsrecordstore
          com.apple.imessage
          com.apple.imservice
Move them all to the Desktop. There may also be a file with the name "com.apple.imagent.plist". Move that to the Trash.
Also in the Preferences folder, there's a subfolder named "ByHost". Open it and do the same thing.
Log out and log back in. Test again. This time Messages should perform normally, but your settings will be lost. You may be able to put back some of the files you moved to the Desktop in this step. Relaunch and test after each one. Eventually you should find one or more that causes Messages to malfunction. Delete those files and recreate whatever settings they contained.
If the issue is still not resolved, quit Messages again and put all the items you moved to the Desktop back where they were. You don’t need to replace the items you moved to the Trash. Stop here and post your results.
If you later decide that you don’t like the results of Steps 3 and 4, you can undo them completely by quitting Messages and restoring the items you deleted in those steps from your backup.

To perform database update in a module with AT EXIT-COMMAND addition

Dear All,
I have a function code 'EXIT' with function type 'E'. When this function code is triggered, my screen should close.
In the module that handles this function code (defined with AT EXIT-COMMAND addition), I will prompt the user whether he/she want's to save the data before exiting with the POPUP_TO_CONFIRM_STEP function module. The text message in the dialog box is "Do you want to save before exiting?".
When the user wants to save the data, a simple UPDATE statement will be executed to write the data on screen to database.
The problem here is since the module is defined with AT EXIT-COMMAND addition, the data on screen won't be copied to their corresponding variable on the code (correct me if I'm wrong). Therefore, even though database update is performed, the data written to database are no different that the original.
How to perform database update in a module with AT EXIT-COMMAND addition?
or
Is it even a "custom" or a "good practice" to prompt user to save data before exiting?
Thanks in advance,
Haris

With an exit command, if there's anything that would be lost, I would prompt "Data will be lost, do you wish to continue?". If they do, the database is not updated, if they don't, they stay in the transaction.
This is because the exit command runs before validation. So how can you know the data is correct?
If you have a button to leave the transaction that isn't an exit command, then you could prompt to save instead. There the choices should be - quit without saving, save and quit, don't quit.
Doing a database update in an exit command is not a good idea.
