How Publisher overwrite the existing source document

[#1]

Hello Qlik Folks,

I just wonder how Qlikview Publisher over write the existing source documents.

(2015-12-03 10:48:50) Information: The Source Document was reloaded successfully.

(2015-12-03 10:48:50) Information: Reload finished successfully

(2015-12-03 10:48:50) Information: Start saving document

(2015-12-03 10:48:57) Information: Check in document: \\servername\QVSource\CIM\UserProfile\UserProfile.qvw

(2015-12-03 10:48:57) Information: Closing the document.

(2015-12-03 10:48:57) Information: Closed the QlikView Engine successfully. ProcessID=146136

I am just curious how exactly Publisher over write the existing source document and whats going on after start saving document step in the log ?

Looks like you distributed it the Source folder.  Instead you should distribute it to the User folder.

Bill, we are distributing to Used Documents folder & I seen those info on later part of the log file.

Generally, Qlikview distribution service follow below steps to overwrite the existing used document:

1. First creates the temp file

2. Delete the old file

3. rename the temp file to original file.

All these steps are logged into task log.

Information: Performance data (CopyFile): FileSystemAccessRules=4 (0), Creating temporary file: \\servername\QVPublic\publish\UserProfile.tmp (0), Temporary file written successfully. (156), Deleting old destination file. (156), Renaming temporary file to destination file. (171), Write complete. (171)

I just wonder, how source document will overwrite with new file ? is the same process like above or ?

‌i think the temp copy is used when document compression is enabled. The .tmp copy is where the compressed version is built and then renamed. If you use compression = none, it just overwrites the qvw file directly.

Thanks for reply Rob.

We set Compression to High. (User Properties --> Save --> Compression = High)

Why the source document overwrite procedure did not logged into task log like user document overwrite? Is there any setting on QEMC to enable this logging to Task log ?
