Is it possible to create a Webservice in BI which takes XML as an input and gives PDF as output with an additional requirement that Siebel expecting the XSD from BI to send data in the BI requested format. Siebel wants to send the data as xml to BI but not sure of the BI capabilities on giving WSDL embedded with XSD (input is a hierarchical)
Hi All,
I am able to fulfil above requirement. Now I am stuck at below point. Need your help!
Is there any way to UPDATE the XML file attached to a Data Definition (XML Publisher > Data Definition) using a standard package or procedure call or may be an API from backend? I am creating an XML dynamically and I want to attach it to its Data Definition programmatically using SQL.
Please let me know if there is any oracle functionality to do this.
If not, please let me know the standard directories on application/database server where the XML files attached to Data Definitions are stored.
For eg, /$APPL_TOP/ar/1.0/sql or something.
Regards,
Swapnil K. -
<rant>I have seen many people complaining about this. I've seen lots of suggestions; change your POP3 SSL number, twist your knee backwards whilst standing on just your little finger. Nothing works. I'd like to not have to migrate to a new Mail software.

I thank you.
<Edited by Host>MY SOLUTION REPOSTED FROM ANOTHER THREAD:
I've just solved a similar issue.
I have a dedicated server running Plesk 9.5 and when I upgraded to iLife 11 and Snow Leopard this error appeared. I could quickly click "get mail" and I'd get all my mail, but only 3-4 of my 9 mail accounts would connect. Theo others would have the error:
"The server error encountered was: The attempt to read data from the server..."
I found solutions for those using IMAP mail:
modify the /etc/courier-imap/imapd configuration file and change MAXDAEMONS from 40 to 80 and MAXPERIP from 4 to 40. This allows all the machines behind my home firewall to connect to multiple accounts on the e-mail server with mailbox caching enabled.
I'd made this change on my server but it didn't seem to have any effect. It dawned on me that I'm using POP, not IMAP. So I found in /etc/courier-imap/pop3d the same settings. I changed the MAXDAEMONS from 40 to 80 and MAXPERIP from 4 to 40 and voila, all my connections concurrently worked.
This has taken me more than two days to fix and I hope posting this helps someone else with the same issue. -
For some business requirements, users want to extract values from a multi-value enabled lookup column
and add items to another list based on each separate value. In contrast, others want to find duplicate values in the list and merge associated values to a multi-value enabled column and then
add items to another list based on the merged value. All of these can be achieved using SharePoint Designer 2013 Workflow.

How to
extract values from a multi-value enabled lookup column and
add items to another list based on each separate value using SharePoint Designer 2013.
For example, they have three lists as below. They want to
extract values from the Destinations column
in Lookup2 and add items to Lookup3 based on each country and set Title to current item: ID.
Lookup1:
Title (Single line of text)
Lookup2:
Title (Single line of text), Destinations (Lookup; Get information from: Lookup1 in Title column).\
Lookup3:
Title (Single line of text), Country (Single line of text).
Important action
1. Loop Shape: SharePoint Designer 2013 support two types of loops: loop n times and loop with condition.
Loops must also conform to the following rules:
Loops must be within a stage, and stages cannot be within a loop.
Steps may be within a loop.
Loops may have only one entry and one exit point.
2. Utility Actions: It contains many actions, such as ‘Extract Substring from Index of String’ and ‘Find substring in String’.
Three scenarios
We need to loop through the string returned from the look up column and look for commas. There are three
scenarios:
1. No comma but string is non-empty so there is only one country.
2. At least one comma so there is at least two or more countries to loop.
3. In the loop we have consumed all the commas so we have found the last country.
Things to note
There are two things to note:
1. "Find string in string (output to Variable:index)" will return -1 if doesn't find
the searched for string.
2. In the opening statement "Set Variable: Countries to Current Item:Destinations" set the return
field as "Lookup Values, Comma Delimited".
Steps to create Workflow
Create a custom list named Lookup1.
Create a custom list named Lookup2, add column: Destinations (Lookup; Get information from: Lookup1 in Title column).
Create a custom list named Lookup3, add column: Country (Single line of text).
Create a workflow associated to Lookup2.
Add conditions and actions:
Start the workflow automatically when an item is created.
Add item to Lookup2, then workflow will be started automatically and create multiple items to lookup3.
See the below in workflow History List:
How to merge values to a multi-value enabled column and add item to another list based on the
merged value using SharePoint Designer 2013
For example, they have three lists as below. They want to find duplicate values in the Title column in
Lookup3 and merge country column to a multi-value enabled column and then add item to lookup2 and set the Title to Current Item: Title.
Lookup1:
Title (Single line of text)
Lookup3:
Title (Single line of text), Country (Single line of text).
Lookup2:
Title (Single line of text), Test (Single line of text).
Important actions
"Call HTTP Web Service"
action: In SharePoint 2013 workflows, we can call a web service using a new action introduced in SharePoint 2013 named Call HTTP Web Service. This action
is flexible and allows you to make simple calls to a web service easily, or, if needed, you can create more complex calls using HTTP verbs as well as allowing you to add HTTP headers.
“Build Dictionary"
action:
The Dictionary variable type is a new variable type in the SharePoint 2013 Workflow.
The following are the three actions specifically designed for the Dictionary variable type: Build Dictionary, Count Items in a Dictionary and Get an Item from a Dictionary.
The "Call HTTP Web Service" workflow action would be useless without the new "Dictionary" workflow action.
Things to note
The
HTTP URI is set to https://sitename/_api/web/lists/GetByTitle('listname')/items?$orderby=Id%20desc and the HTTP method is set to “GET”. Then the list will be sort by Id in descending order.
Use Get
d/results(0)/Id form
Variable: ResponseContent (Output to
Variable: maxid) to get the Max ID.
Use Set
Variable: minid to Current List:ID to get the Min ID.
Use Copy from
Variable: destianation , starting at
1 (Output to
Variable: destianation) to remove the space.
Steps to create Workflow
Create a custom list named Lookup1.
Create a custom list named Lookup2, add column: Test (Single line of text).
Create a custom list named Lookup3, add column: Country (Single line of text).
Create a workflow associated to Lookup3.
Add a new "Build Dictionary" action
to define the http request header:
Add a Call HTTP Web Serviceaction, click on
this and paste your http request.
To associate the
RequestHeader variable, select the Call action property,
set the
RequestHeaders property to
RequestHeader:
In the Call action, click on
response and associate the response to a new
variable: ResponseContent (of type Dictionary).
After the Call action add Get item from Dictionary action to get the Max ID.
Add Set Workflow Variable action to get the Min ID.
Add Loop Shape (Loop with Condition) to get all the duplicate titles and integrate them to a string.
Create item in Lookup2.
The final Stage should look like this:
Start the workflow automatically when an item is created.
Add item to Lookup3, then workflow will be started automatically and create item to lookup2.
See the below in workflow History List:

http://sergeluca.wordpress.com/2013/04/09/calling-the-sharepoint-2013-rest-api-from-a-sharepoint-designer-workflow/GREAT info, but it may be helpful to note that when replacing a portion of the variable "Countries" with a whitespace character, you may cause the workflow to fail in a few specific cases (certain lookup fields will not accept this and will automatically
cancel). I only found this out when recreating your workflow on a similar, but much more complex list set.
To resolve this issue, I used another utility action (Extract Substring from Index of List) to clear out the whitespace. I configured it as "Copy from
Variable: Countries, starting at
1 (Output to Variable: Countries), which takes care of this issue in those few cases.
Otherwise, WOW! AWESOME JOB! Thanks! :) -

Delete everything in Sharepoint 2013 and start from a begining
How do you delete all the settings, databases in Sharepoint 2013 and start from a begining.
We have some problems that PictureURL is wrong and some other thing ain't working right. Because Sharepoint 2013 is in our test environment we would like to delete all settings, databases including PictureURL info, which I don't know which SQL database holds
that information?
bostjancThe pictureURL parameter is either going to be in the specific site collection in the User Information List, or it is going to be in the User Profile Synchronization Service Application, which is what syncs over to the User Information List. You will need
to identify exactly what you are trying to clear out. If you are not using User Profile Synchronization in your test environment then the following will help you find and delete the appropriate Site Collection or content database.
Any content is going to be Site Collection specific, so if you are setting the pictureURL for a user in http://portal.domain.com/sites/somesitecollection then that Site Collection will be in a specific database which may also contain other Site Collections.
To find out which database a Site Collection is in go to Central Administration -> Application Management -> Site Collections -> View All Site Collections. Here you can find the Site Collection you are browsing to. When you select it you will see
what content database it is in. You can also just delete the Site Collection here without the need to delete the entire content database. Instead of clicking View All Site Collections in the steps above click Delete a Site Collection. That is probably the
better route to go.
If you are using the User Profile Synchronization and this is where the picture URL is set then you will want to go to Central Administration -> Application Management -> Service Applications -> Manage Service Applications -> Click your User
Profile Service App and then view the user profiles. Find the user you want to remove the pictureURL for and edit that user profile to remove the picture.
Hope that helps!

Hi,
Following the upgrade to iOS 7.0.3 on all our iPhone and iPad devices, it has been identified that when sending emails around 100KB in size and over an error message appears on the device stating “Cannot Send Mail The message was rejected by the server because it is too large.” See error message below. The send/receive limit is over 10MB so this is not the issue.
We are in an Exchange Environment using Microsoft Activesync. This issue is not evident in iOS 6. This has been tested on an iPhone 3GS running version iOS 6.1.3. We have been unable to repeat the issues seen on iOS 7 on the older OS. It is not possible to roll back to the older operating system as Apple are no longer signing the software.
We use Microsoft Active Sync to connect to our Exchange servers through a TMG. The issue is very inconsistent, some identical emails go through, some fail. This is not an issue with the send/receive limit as this is over 10MB. The error message when it fails on the TMG is Status: 413 Request Entity Too Large, which we believe is from IIS on the CAS server.
Does anyone have any suggest course of actions to take?
Many ThanksThis resolution have to attend at the server not with the ios device. My employer's mail administrator reject me to correct it from the server. As his concern is, if ither ios devices works why don't mine? So I am helpless than changing my iphone. It works fine for early versions of ios and with androids. And also one of my friends iphone4 with ios 7 (similar as mine) works too. So I guess it's something wrong with my iPhones settings. But basic question I cannot understand is it works in my phone before this ios7 upgrading. And currently working with my yahoo account too. Favourable reply expected.

My Mail program has gone south on Leopard on my 27-month old Macbook. I can't send, even though the server details are correct. I tried reinstalling the Mail program from the install DVD, but no go; apparently that two-year old Mail is no longer compatible with my up-to-date Leopard. I tried deleting the account (hotmail) from Mail and setting up a different account (Yahoo). After loading all the inbox two things happened: first, I still couldn't send, and second, when I closed the Mail window the whole inbox then disappeared and doesn't come back. Although I couldn't reinstall the Mail program from the install DVD, would it still be possible to reinstall the whole system from that DVD? If I do, will I lose files or will there be another problem since that DVD is now over two years old?
Thanks for any suggestions; they will be much appreciated.
P.S. I've just noticed that now I can't change the desktop picture: I go through the motions in Preferences, but the new picture doesn't appear on the desktop. Is there a systemic problem?You are waiting for an apology to something that happened over a year ago? Really? This is why there is a manager in the store. You have a problem with an employee you speak to the manager. Just like you did on the phone. You would have gotten your apology in July 2013.
Here is the information about your upgrade fee.
Upgrade Fee
It is because when you have a problem you (customers) go running to the store and want to take up the time of the reps to fix it. Other carriers have third parties that deal with technical support and those locations are few and far between. VZW provides this directly through their stores. Also, when you subsidize a $650 and pay $200 VZW has to pay $400. Your monthly service fee doesn't begin to scratch the surface of paying that back. Not with all the money that is put into the network and its improvements.
Then over a year later you get someone on the phone who apologized and offered to waive the fee on your phone and you didn't take it? That offer won't come down the pike again.
One thing you should know is that all these employees are people and as such they sometimes come off cross. I doubt that you speak to everyone so sweetly all the time. Cut them a little slack and put this whole thing behind you after 15 months. Either upgrade with VZW or move on. -
Having been on Thunderbird for some years I have suddenly got the following message when trying to send mail.
An (SMTP) error occurred while sending mail. The server responded: Requested action aborted: This mail account has sent too many messages in a short amount of time. Please try later..
I have checked the SMTP server settings in tools, account settings and they are as they have always been. Is there something I have missed?Sending through web mail is totally irrelevant to using an SMTP server. The message even says it is from the server. Why do you think this is a Thunderbird problem.
The provider has put in place measures to keep people from spamming other email recipients using thier SMTP server. You have seen the result of those measures. -
Cannot send email from my iPhone or iPad. The server rejects a recepient for no apparent reason. The recipient is not new. This issue happens on reply or reply to all or froward; not a new email to the same recepient. What is happening?
I talked with a tech today and he said I cloud is having problems which should be resolved shortly.
In the mean time I used the .me smtp server settings which allowed me to send mail. -
I upgraded to FF4 and have not been able to download a single PDF file. I get a message sending me to the Apple Quicktime site for additional plug ins but no information on what I am to upload. Next time it happens I will copy the exact statement. This is very frustrating as I need to be able to download PDFs to get some required files.

Nonsense. First, what pages are printed does not depend on the printer driver, but on the application. The driver prints whatever the application sends to it. Second, Mac OS X's bundled PDF viewer, Preview (there are others) even has a dedicated command for this function -- File > Print Selected Pages…, or ⌥⌘P. -
SharePoint 2013 code for the SharePoint Config database stored procedure dbo.proc_getObject has been changed from SharePoint 2010 with the difference of select with nolock.
I am seeing numerous Error 7886, Severity-20 errors nightly:
"A read operation on a large object failed while sending data to the client. A common cause for this is if the application is running in READ UNCOMMITTED isolation level. This connection will be terminated."
Here I have commented out "with (nolock)" to 'fix' the error and to align the store proc with SharePoint 2010 code :
ALTER PROCEDURE [dbo].[proc_getObject]
@Id uniqueidentifier,
@RequestGuid uniqueidentifier = NULL OUTPUT
AS
SET NOCOUNT ON
SELECT
Id,
ParentId,
ClassId,
Name,
Status,
Version,
Properties
FROM
Objects --with (nolock)
WHERE
Id = @Id
RETURN 0
How is this stored procedure called and for what use?
Why did Microsoft make this change to SharePoint 2013 - some performance gain through dirty reads at the cost of stability? Or what could be a reason for this to happen that can be fixed?GetObject retrieves any farm object that is selected (by ID). Changing this is obviously not supported, and NoLock was used to (help) prevent locks when performing a select query.
I've never seen this issue, and would guess it is unique to your environment given this is such a core piece of the SharePoint infrastructure.

Object can't be send over to the server.
Hi to everyone,
I'm doing a connection between client and server. The client will send image from the platform to the server. The server will then create an folder in the server-side to store the images.
Thank you for reading. Hope to hear from you soon. Anytime you need clarifation, you could ask. I'll be more willingly to feel you in in more details.

* getImage() assumes that a connection already exists to the server.
* First, getImage transmits the image we want to get.
* Then, we wait to read the 3 objects sent by the server's ObjectOutputStream:
-- an Integer object, representing the width of the image
-- an Imteger object, representing the height of the image
-- an Image object
* The first two are Integer objects, NOT primitive int types. This
* is because the ObjectOutputStream can only transmit objects, not primitive
* types (to transmit primitive types, use a DataOutputStream).
* 1: Read the three objects sent by the server. Note each object must be cast to
its appropriate type, since readObject() returns an Object. To get the value
of an Integer object, we use its intValue() method, which returns the primitve
int value of the Integer.
* 2: The buffer object is an array of integers, which represents the image
data. In other words, buffer is an array of integers in memory which is
the source of the raw image data. Java has a special MemoryImageSource
class which is used to construct Images from raw data in memory. So, in
step 3, we create a MemoryImageSource object using the width, height, and
buffer objects.
* 3: We want to create an Image object using the MemoryImageSource object we
created in step 3. To do this, we use the createImage() method of the
Component class. Since this client class extends Frame, and Frame is a
subclass of Component, we can call createImage() directly.
* 4: Once the Image is created, it will be passed into the folder for storage

Please clarify with me if i'm not clear, thank a lot. Any help will be appreaciated.

Can I close the connection after sending immediately on the server?
I have a C/S program. On the server side, the process as following:
1. accept (blocking)
2. //a connection is established
using a new socket to receive request data from client
3. business processing ... (maybe several seconds)
4. send response data to client
5. close socket immediately
6. listening continuely again
The server side is running on linux and writed by Java, and client is running on windows and writed by C++ Builder.
My problem is:
1. if the server is running on windows, everything is OK.
2. if the server is running on linux (that is exprcted), the client can not receive the response data from server, the client program said the connection is unavailable when he read from socket blockingly.
3. if I add some delay, e.g. 500ms, between sending response and close the connection, the client can receive response normally.
why above?
thanks for help.

If I uncomment "Thread.sleep(500);", it means wait some time before close socket, the client can receive all response data.
why? -
The message was rejected by the server
My hotmail account gives the message was rejected by the server, even when I send a new one just testing the account.
After that, I receive an email from Outlook.com asking me to sign in to Outlook and verify my account.
