SystemRequest (Oracle NoSQL Database SDK for Java 5.3.7)

- oracle.nosql.driver.ops.Request

```
public class SystemRequest
extends Request
```
On-premise only.
SystemRequest is an on-premise-only request used to perform any table-independent administrative operation such as create/drop of namespaces and security-relevant operations (create/drop users and roles). These operations are asynchronous and completion needs to be checked.
Examples of statements used in this object include:
- CREATE NAMESPACE mynamespace
- CREATE USER some_user IDENTIFIED BY password
- CREATE ROLE some_role
- GRANT ROLE some_role TO USER some_user
Execution of operations specified by this request is implicitly asynchronous. These are potentially long-running operations. NoSQLHandle.systemRequest(oracle.nosql.driver.ops.SystemRequest) returns a SystemResult instance that can be used to poll until the operation succeeds or fails.
The statements are passed as char[] because some statements will include passwords and using an array allows the memory to be cleared to avoid keeping sensitive information in memory.
