```
- Method Detail
  - scheduleStorageSessionMaintenance
```
public void scheduleStorageSessionMaintenance()
```
  - storageSessionMaintenance
```
public void storageSessionMaintenance(javax.ejb.Timer timer)
```
    If the session is not initialized then attempt to initialize it. If the session is initialized then verify to ensure that the session uses the latest set of credentials.
    
    Parameters:
    timer -
  - init
```
public boolean init()
```
    Returns:
    if the storage subsystem is running or if a session was initialized, otherwise
  - refreshCredentialsAndSession
```
public boolean refreshCredentialsAndSession()
```
    Checks the system configuration to see if the storage credentials changed from when the current session got initialized. 1) If the credentials are identical then no changes are required and the current session is good. 2) If the credentials are different then create a new session with the new credentials and register it with the session manager.
    
    Returns:
    if a new session was sucessfully created or no new session is required; otherwise
