MirrorPersistenceFailureAlert (GigaSpaces 16.4.0 API)

java.lang.Object
- org.openspaces.admin.alert.alerts.AbstractAlert
- - org.openspaces.admin.alert.alerts.MirrorPersistenceFailureAlert

All Implemented Interfaces:

Externalizable, Serializable, Alert
```
public class MirrorPersistenceFailureAlert
extends AbstractAlert
```
A Mirror persistency failure alert, triggered upon a failed replication from primary Space to Mirror Space, due to an error (e.g. a DB error). The alert is raised when the replication channel has encountered an exception reported by the Mirror target. The alert is resolved when the Mirror manages to persist to the DB for first time after the alert has been triggered.
This alert will be received on the call to AlertTriggeredEventListener.alertTriggered(Alert) for registered listeners.

Since:

8.0

- Method Detail
  - getComponentUid
```
public String getComponentUid()
```
    The component UID is equivalent to GridComponent.getUid()
    
    Specified by:
    
    getComponentUid in interface Alert
    
    Overrides:
    
    getComponentUid in class AbstractAlert
    
    Returns:
    
    Component UID - the unique identifier of the component associated with the alert.
  - getHostAddress
```
public String getHostAddress()
```
    The host address of the machine that this alert corresponds to.
    
    Returns:
    
    the host address; may be null.
  - getHostName
```
public String getHostName()
```
    The host name of the machine that this alert corresponds to.
    
    Returns:
    
    the host name; may be null.
  - getVirtualMachineUid
```
public String getVirtualMachineUid()
```
    The uid of the virtual machine that this alert corresponds to.
    
    Returns:
    
    the virtual machine uid; may be null.
  - getInconsistencyReason
```
public String getInconsistencyReason()
```
    The reason why a source (primary Space) could not replicate to a target (Mirror Space). This reason could be failure to persist to a database, a failure to replicate to due memory shortage, failure to connect to target, etc. The failure is given as a full stack trace of the original exception.
    
    Returns:
    
    the inconsistency reason; may be null.
