Expected behavior

load multiple schema from oracle database in the readwrite-splitting scenario

Actual behavior

only load one schema(same as databaseName)

Reason analyze (If you can)

Single Table only load the schema same as databaseName from oracle database.

Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.

I tried every way I found from the single table document , but every time the second schema don't load in the ShardingSphereDatabase. Is It my config error or a limitation on oracle ?

Example codes for reproduce this issue (such as a github link).
