    By default concurrency is optimized and the cache is not locked during reads or writes, This allows for concurrent reading and writing and should never cause any problems. If the application uses no form of locking the last unit of work to merge changes will win, with no locking it is possible only under this scenario for two unit of works to merge changes different than the database although highly unlikely and if occurred is the entire purpose of locking. This property allows for the isolation level of changes to the cache to be configured for sever situation and it is not suggest that this be changed.

    ADVANCED: By default concurrency is optimized and the cache is not locked more than required during reads or writes, This allows for virtual concurrent reading and writing and should never cause any problems. If the application uses no form of locking the last unit of work to merge changes will win, with no locking it is possible only under this scenario for two unit of works to merge changes different than the database although highly unlikely and if occurred is the entire purpose of locking and locking is the suggested solution if this is a problem. This property allows for the isolation level of changes to the cache to be configured for sever situations and it is not suggest that this be changed.
    Setting are:
    - ConcurrentReadWrite - default
    - SynchronizedWrite - only allow a single writer (i.e. unit of work merge) to the cache at once
    - SynchronizedReadOnWrite - do not allow reading or other unit of work merge while a unit of work is in merge

```
public DatabasePlatform getPlatform()

  - getDatasourcePlatform
```
public org.eclipse.persistence.internal.databaseaccess.Platform getDatasourcePlatform()

  - getTableQualifier
```
public java.lang.String getTableQualifier()
```
    PUBLIC: Return the qualifier for the all of the tables referenced by EclipseLink. This can be the creator of the table or database name the table exists on.

  - isConnectionHealthValidatedOnError
```
public boolean isConnectionHealthValidatedOnError()
```
    PUBLIC: This value defaults to false when not on a DatabaseLogin as the functionality has not been implemented for other datasource type. On an SQL Exception EclipseLink will ping the database to determine if the connection used can continue to be used for queries. This should have no impact on applications unless the user is using pessimistic locking queries with 'no wait' or are using a query timeout feature. If that is the case and the application is experiencing a performance impact from the health check then this feature can be turned off. Turning this feature off will prevent EclipseLink from being able to retry queries in the case of database failure.
