All Implemented Interfaces:

public class WeightedSiteMinderJobClass
extends JobClass

This class defines a SLAMD job that simulates the load that SiteMinder can place on an LDAP directory server using a weighted access pattern. The load that it uses is based on the following (rather inefficient) sequence of events:

1. Perform a subtree search from the directory suffix to find the user's entry based on a login ID.
2. Perform a base-level search on the user's entry to retrieve the objectClass attribute.
3. Perform a bind as the user. This is done on a different connection than all of the other steps.
4. Perform a base-level search on the user's entry to retrieve a given user-specified attribute (attr1).
5. Perform a base-level search on the user's entry to retrieve a second user-specified attribute (attr2).
6. Perform a base-level search on the user's entry to retrieve the first attribute (attr1).
7. Perform a modification on the user's entry.
8. Perform a base-level search on the user's entry to retrieve the first attribute again.
9. Perform a base-level search on the user's entry to retrieve the first attribute again.
10. Perform a base-level search on the user's entry to retrieve a third attribute (attr3).

Constructor Detail

WeightedSiteMinderJobClass

public WeightedSiteMinderJobClass()

Creates a new instance of this job thread. This constructor does not need to do anything other than invoke the constructor for the superclass.

Method Detail

getJobName

public java.lang.String getJobName()

Returns the user-friendly name that is to be used for this job class in the administrative interface.

Specified by:

getJobName in class JobClass

Returns:

The user-friendly name for this job class.

getJobDescription

public java.lang.String getJobDescription()

Returns a description of this job that can be seen in the administrative interface.

Specified by:

getJobDescription in class JobClass

Returns:

A description of this job class.

getJobCategoryName

public java.lang.String getJobCategoryName()

Retrieves the name of the category in which this job class exists. This is used to help arrange the job classes in the administrative interface.

Overrides:

getJobCategoryName in class JobClass

Returns:

The name of the category in which this job class exists.

getParameterStubs

public ParameterList getParameterStubs()

Returns the set of parameters whose value may be specified by the end user.

Specified by:

getParameterStubs in class JobClass

Returns:

The set of configurable parameters for this job class.

getStatTrackerStubs

public StatTracker[] getStatTrackerStubs(java.lang.String clientID,
                                         java.lang.String threadID,
                                         int collectionInterval)

Retrieves the set of stat trackers that will be maintained by this job class. The stat trackers returned by this method do not have to actually contain any statistics -- the display name and stat tracker class should be the only information that callers of this method should rely upon. Note that this list can be different from the list of statistics actually collected by the job in some cases (e.g., if the job may not return all the stat trackers it advertises in all cases, or if the job may return stat trackers that it did not advertise), but it is a possibility that only the stat trackers returned by this method will be accessible for some features in the SLAMD server.

Specified by:

getStatTrackerStubs in class JobClass

Parameters:

clientID - The client ID that should be used for the returned stat trackers.

threadID - The thread ID that should be used for the returned stat trackers.

collectionInterval - The collection interval that should be used for the returned stat trackers.

Returns:

The set of stat trackers that will be maintained by this job class.

getStatTrackers

public StatTracker[] getStatTrackers()

Retrieves the set of stat trackers that are maintained by this job class.

Specified by:

getStatTrackers in class JobClass

Returns:

The set of stat trackers for this job class.

providesParameterTest

public boolean providesParameterTest()

Indicates whether this job class implements logic that makes it possible to test the validity of job parameters before scheduling the job for execution (e.g., to see if the server is reachable using the information provided).

Overrides:

providesParameterTest in class JobClass

Returns:

true if this job provides a means of testing the job parameters, or false if not.

testJobParameters

public boolean testJobParameters(ParameterList parameters,
                                 java.util.ArrayList outputMessages)

Provides a means of testing the provided job parameters to determine whether they are valid (e.g., to see if the server is reachable) before scheduling the job for execution. This method will be executed by the SLAMD server system itself and not by any of the clients.

Overrides:

testJobParameters in class JobClass

Parameters:

parameters - The job parameters to be tested.

outputMessages - The lines of output that were generated as part of the testing process. Each line of output should be added to this list as a separate string, and empty strings (but not null values) are allowed to provide separation between different messages. No formatting should be provided for these messages, however, since they may be displayed in either an HTML or plain text interface.

Returns:

true if the test completed successfully, or false if not. Note that even if the test did not complete successfully, the user will be presented with a warning but will still be allowed to schedule the job using the provided parameters. This is necessary because the parameters may still be valid even if the server couldn't validate them at the time the job was scheduled (e.g., if the server wasn't running or could not be reached by the SLAMD server even though it could be by the clients).

initializeClient

public void initializeClient(java.lang.String clientID,
                             ParameterList parameters)
                      throws UnableToRunException

Performs initialization for this job on each client immediately before each thread is created to actually run the job.

Overrides:

initializeClient in class JobClass

Parameters:

clientID - The ID assigned to the client running this job.

parameters - The set of parameters provided to this job that can be used to customize its behavior.

Throws:

UnableToRunException - If the client initialization could not be completed successfully and the job is unable to run.

initializeThread

public void initializeThread(java.lang.String clientID,
                             java.lang.String threadID,
                             int collectionInterval,
                             ParameterList parameters)
                      throws UnableToRunException

Initializes this job class with the information that it will use when actually running the job. This will also initialize the stat trackers used by the job.

Specified by:

initializeThread in class JobClass

Parameters:

clientID - The thread ID for this thread.

threadID - The thread ID for this thread.

collectionInterval - The collection interval to use for gathering statistics while processing the job.

Attempts to force this thread to exit by closing the connection to the directory server and setting it to null.

Overrides:
