1. Question:
When querying a layer, it will report an error and cannot link to oracle, but the layer service can still run and the layer can be loaded.
The error is as follows:
Unable to complete operation. Failure to access the DBMS server [ORA-03114:未连接到 ORALCE ] [SDE.xxx]
2. Problem solving:
Increase the maximum number of instances and then restart the layer service.
Click on the layer - pooling - change the maximum number of instances to 10
If you use a lot of clients, you can appropriately increase the size of the maximum number of instances
