Hi Pravin,

Thank you for your very detailed answer.

However, on investigation, I found that I didn't need any of this, as all the client and server configurations are stored in the HSSYS database, as are the access tokens, when they are created.

The %SYS namespace then contains a global mapping for OAuth2.* from the HSSYS database.

So, by mirroring the HSSYS database and setting the 'Customization namespace' to HSSYS in the OAuth2 server configuration, allows OAuth2 to continue to work after a failover.


Hi McLean,

Thank you for your reply, very useful.

With regards to failover and the necessary OAuth2 components this was my biggest concern as I had assumed these components where store in the %SYS database, which isn't mirrored.

However, you saying that they are stored in the HealthShare database made me think and I can now see that they there is a global mapping for the HSSYS database, which can, I'm sure, be mirrored.

I have gone through a lot of documentation, but is there any particular links, that relate to this specific area that you could pass on?

Thanks again.


Also try putting brackets around the top number of rows, Jerry,  i.e.: TOP (100).

I've known this to be a problem for me with linked tables.
