I want to update all mapservice connections on Arcgis for Server 10.5.1

Our current Oracle database has to be migrated to another host. The new host already contains a couple of databases, so it isn't possible to maintain the same hostname. 

The Arcgis Server mapservices data connections therefore need to be updated to connect to the new database. Is there functionality in Arcgis Server 10.5.1 to update all connections at once or to update a connection for a mapservice?

The alternative is to republish all mapservices. I can write a python script to get the security and mapservice settings as json, get the MXD files from the server directory, update the MXD data connection, generate SD and republish the SD using the stored json settings, but this will take more time and might be more error prone.

You can look into externalizing the connection strings and then updating the data store within Manager:

Upgrade ArcGIS Server—Documentation | ArcGIS Enterprise 

The link title is misleading.  It's supposed to be for password changes but should work for hostname changes.

Thanks 🙂

I think I can test this very easy: I will modify the host file in Windows on my ArcGIS Servers and on my ArcGIS desktop machine. In the host file I will put a new hostname for the existing Oracle host and generate  new SDE files files. I will update the SDE files at my ArcGIS Server and follow the instructions you linked. 

Hopefully, it will work for my managed datasource as well.

I need to upgrade our database connection as well with a new instance name. Were you able to update your existing web services with the External Connections Strings tool?

Yes, this worked for updating the instance name.

The old instance name however sticks in the connection name when you look in the Service Workspace. When you select the connection name and look at the Workspace Properties, the connection properties and server show the new instance.

Another issue was that the Externalize Connection string tool crashed a couple of times for unknown reasons. I therefore ran the tool until it completed with exit code 0.

Make good backups of your Arcgis Server configuration and database, I did not need them, but you never know what can go wrong.

Thanks for responding.

I get the error “Update failed” for every service that was reported back from the ExternalizeConnectionString tool. When I look at the workspace I still see the old instance name. I also restarted one of the services hoping it would use the new connection, but I get this error “ Service started with errors

pspPoliceBeat.MapServer:

Instance of service 'pspPoliceBeat.MapServer' started with errors. The Layer:'pspPoliceBeat' in Map:'Police' is invalid. The base table definition string "gisdata.SDECB.PoliceBeat" is invalid. The item was not found.

Did you use ArcPro to publish your services? Did use the same sde connection file and just modified the instance name and re-import the connection file in the data store page?

Looks the is a solution for changing a password and host  name , but I am looking to update my connection into a new oracle user that is the same host but different Oracle user.

Our old Oracle user got read only permission and in 10.6.1 such user is not supported (BUG). Why are Esri forcing us to have a user with read and write permission is another question. And the easiest solution as stated in the BUG is  to give the user a full permission but this user is called by many other application indipendent of our ArcGIS server services.  So given it a full permission is not an option.

The quesion is, is it possible to change the user name (ofcurse different password but the same host name) of my ArcGIS server service connection?

thanks!

All my mapservices were published using ArcMap.

If I remember correctly did the following steps:

Using the old database, I ran the  ExternalizeConnectionString tool from the command line until it successfully finished.

The Database administrator then moved all the data to the new instance

I updated the SDE files for the new instance.

With these new SDE files I updated my registered databases on ArcGIS Server

Restarted the ArcGIS Server to force a restart of all mapservices

All mapservices started without error.

I ran the ExternalizeConnectionString after I updated the datastore with the new sde file. I thought I was suppose to run the tool after I update the sde file with the new instance.

Thanks for listing your steps.

Does anyone understand what the ExternalizeConnectionString tool actually does. After reading the steps provided by  Joël Hempenius I think I have an understanding, but I would feel a lot better if I knew what it did. Thank you for everything and have a delightful day.

Sincerely,
