Interation Broker:The 'IsChanged=Y' flag is always present in the XML's , what are they ? and what do they signify ?

By -
When sending and receiving messages, all blank data values get stripped. As a result, you cannot determine if a field value is blank by definition, or if its value was stripped in the messaging process.
The PeopleCode functions - CopyRowset, CopyRowsetDelta and CopyRowsetDeltaOriginal, feature an IsChanged attribute that automatically gets set to identify fields that have been changed. Any field that has been changed displays the attribute IsChanged="Y".

Note. The IsChanged attribute applies only to rowset-based messages.
It does not apply to nonrowset-based messages, including container messages, or part messages.

If you are writing subscription PeopleCode you reference the IsChanged value of the field in the message rowset, as always. However, the blanks appear with the attribute IsChanged="Y".

Transferring a file using SFTP to specified target location: (Thanks to Jawahar who helped me in this article) A lot has been mentioned about sFTP support in PT 8.51. Below gives clear idea on SFTP. Are there any specific pre-requirements for using file transfer protocols? Yes. Though FTP can be used directly by giving the URL as a string to the peoplecode method, other protocols (ftps, sftp, http and https) require the URL to be passed as a URL identifier only. When an URL identifier is created, URL properties link on the page gets enabled. Users need to provide the URL properties specific to the protocol they are using on this "URL properties" page. The URL properties differ based on the protocol choosen. Once URL Identifier is ready, it can be used in any of the file attachment peoplecode methods just like the existing way.   What are the authentication methods supported for sftp? Password and Public Key authentication are supported.

Peoplesoft Error: All Processing Suspended: Restart OPRID=PS, RUNID=RUN01, PI=5000(108,503)

By mymithraa -
All Processing Suspended: Restart OPRID=PS, RUNID=RUN01, PI=5000(108,503) What is this about and what should be done? This error can occur when Application Engine programs are restartable and run via the Process Scheduler, and the last run was No Success - And an attempt re-run, rather than re-start will produce error as well The cause of this message is that previously this same AE program was run using the same OPRID=PS & RUNID=RUN01. It was not Successful on initial run, and now an attempt to RUN the same program has occurred, instead of an attempt to RESTART the original that failed. Whether this error Happened in Development??? This message happened while the Customer was in Development phase of this AE program. It could have happened when this AE was in Production as well. However, what to do would have completely different emphasis depending on if this happens in Development or Productions. During the development cycle, we would expect that this AE would have to run many tim
