Hi all,

 

Now we are using the pb2017 r3 webservice function to replace the funtions in EA server before as .net webservice interface.

 

But we set the DB connection in the EA server in connection caches, then the PB just get the CacheName to connect to DB with the old PB. Now does anyone have some thoughts or advice to re-write the DB connection part on the IIS .net server?

Hi Sally;

   For PB2017Rx PB based web services, you can just use an ODBC or ADO.Net client connectivity mechanism and then let those connections handle the DB caching (see MSDN for ODBC and ADO.Net help on accomplishing this).

FYI:  https://docs.microsoft.com/en-us/dotnet/framework/data/adonet/ole-db-odbc-and-oracle-connection-pooling

Hi Chris,

Thanks for replying. We are now deploy the PB code to dll file, then used in .net project. If use ADO.net client to handle the DB cache, how do we use the PB code which is in DLL to call the cache?

Hi Sally;

AFAIK, the cache is managed by the ADO.Net sub-system and transparent to PB.
