We are trying to create custom blob using the sample provided by Sensenet on wiki http://wiki.sensenet.com/How_to_create_an_external_blob_provider ,
But we found there is an object not exist “FileSystemChunkReaderStream” so we are not able to continue practicing how to work with blobs.
Can you please share with us this class FileSystemChunkReaderStream ?
Currently the Reader and Writer stream classes can be found in the Tests project along with the file system blob provider sample. Although if you are using the Community edition, you'll have to wait a bit for the new release because it is behind the Enterprise edition.
In the meantime, please check the wiki link you posted above, I added the two missing stream classes to the article so that you can continue with your project.

I am new to ADF and need some help please.
I created a Linked service for a sql database. I know need to make this dynamic (I know how to do this). I also want to rename the Linked service to reflect this dynamic nature. But I cannot find a way to do this.
Can someone help please? Not many hits in a google search
Thank you
I'm pretty sure you can't rename a Linked Service after it is published. If you want to dynamically create a linked service I would suggest building a small script using the SDK:s that are available like the ArtifactsClient from azure-synapse-artifacts for Python if you're running in Synapse Analytics Data Factory. You might then want to create a Linked Service for each run and tear it down after you've ran your pipelines. There should be an SDK for this in the "regular" Data Factory as well.
EDIT: Just noticed that there's a function for renaming a linked service through the mentioned API. See documentation here.
If your ADF is linked to GIT you can follow these simple steps to rename your linked Service:
Clone your ADF locally
Create a new branch (optionally)
Open ADF code in any Editor and Search and replace Linked Service name in all files (I use VSCode)
Rename Linked Service file name to new name (If not done ADF will prompt an issue)
Commit and push your changes
Verify on ADF (don't forget to switch branch)
Create a pull request to merge your changes to your main branch
I am using Arcgis Online. I want to migrate my feature layers (data which stored in esri's internal database) to external database.
Can anyone help me to figure out how I can do it? Also how can I use external database in my Application(PostgreSQL/Neo4j).What I need is, to host my own database server like neo4j and use as a replacement of feature-table provided by ArcGis.
Thanks,
Tarni
You have many options for downloading data from ArcGIS Online.
If you do not have many feature services, the easiest way would be to go to "My Content", then find your feature service. You should see an "Export Data" option towards the top-right.
If you have multiple feature services, you could repeat the directions above, but choose "Open in ArcGIS Desktop". This will download a file that will set up the connection in ArcMap for you. You can also hit the services directly from ArcGIS Desktop by going to "My Hosted Services" in ArcCatalog and logging in.
Another option is to use a Python script. This may be best if you have alot of data, and if the data is updated frequently. Check out https://github.com/tedrick/SyncSurvey for an example of getting data repeatedly from a feature service.
i want to sync the local db and server , if any data updated in server it should sync with android local db.
i have read the tutorial for syncAdapter from this link
but above link content provider is used, could any one share the details about how to use the sync Adapter with sq-lite DB. or please suggest me any good examples
Refer to stub content provider and custom sync adapter. They have long text but very useful.
Scenario: I have an IBM Domino web application (.NSF) and contains divisions (refer to the image). I want to migrate the content (such as blogs, main content and the article) to my WebSphere Portal. What is the first thing to do?
My understanding in migration is database to database migration and seems I don't know where to find the database for my contents knowing that database in creating domino application is built in. Advance thanks!
Refer to this image: http://postimg.org/image/irxsjdk8p/
The database is the NSF file - although it's possible that the information might be aggregated from several NSF files so you'll have to do some analysis. The first thing to do is to use the Notes client to identify the documents that contain the content that you want to migrate, check their properties to determine what NSF file they are stored in and what form they are based on, and then use Domino Designer to open the NSF file (or files, possibly) and analyze the form and determine which items contain the values that need to be migrated.
My data is stored in the form of a .csv file on another computer, which is like an office server. I am developing an iphone app that requires to read this data during runtime. Note that I can easily parse a csv file given its stored on my system.
As far as I know Java uses socket programming for this. I know there must be a similar provision in Objective C. Please guide me as to what class in Xcode can help me with this.
You can set up a web service in the office server and hit the url for fetching the data. Use NSURLConnection for this.
