handle db connection with rpc server


In our environment we are using REST API to access Natural RPC servers.

I have noticed that the RPC process isn’t closing its db (adabas) connections.
Using ADAOPR DI=UQ_FILE I saw that NATRPC is still holding files that a request that had ran long time ago accessed.
In this case, it is not possible to execute utilities like ADADBM REFRESH, or ADADBM ADD_FIELD.

For me, it means that the REST-API request isn’t a stateless REST-API.

To solve this issue I have written a Natural function that close Adabas conecction, and I have set it in NATRPC01/03 (exit/Error).

I think that the current behavior isn’t suitable or correct for now days (working with REST-APIs).

I would like to have an option that will cause Natural RPC Server to close the connection to the database after every request.

Use Case Natural RPC & Adabas

    The requirement is to have Natural RPC supporting stateless Rest APIs.

    same when a request run usr2005n (mapping db files)

    When another request comes after, it gets the mapping, which is wrong
