@ThreadSafety(level=NOT_THREADSAFE)
public final class ModRate
extends LDAPCommandLineTool
implements java.io.Serializable

This class provides a tool that can be used to perform repeated modifications in an LDAP directory server using multiple threads. It can help provide an estimate of the modify performance that a directory server is able to achieve. The target entry DN may be a value pattern as described in the ValuePattern class. This makes it possible to modify a range of entries rather than repeatedly updating the same entry.

Some of the APIs demonstrated by this example include:

• Argument Parsing (from the com.unboundid.util.args package)
• LDAP Command-Line Tool (from the com.unboundid.util package)
• LDAP Communication (from the com.unboundid.ldap.sdk package)
• Value Patterns (from the com.unboundid.util package)

All of the necessary information is provided using command line arguments. Supported arguments include those allowed by the LDAPCommandLineTool class, as well as the following additional arguments:

• "-b {entryDN}" or "--targetDN {baseDN}" -- specifies the DN of the entry to be modified. This must be provided. It may be a simple DN, or it may be a value pattern to express a range of entry DNs.
• "-A {name}" or "--attribute {name}" -- specifies the name of the attribute to modify. Multiple attributes may be modified by providing multiple instances of this argument. At least one attribute must be provided.
• "--valuePattern {pattern}" -- specifies the pattern to use to generate the value to use for each modification. If this argument is provided, then neither the "--valueLength" nor "--characterSet" arguments may be given.
• "-l {num}" or "--valueLength {num}" -- specifies the length in bytes to use for the values of the target attributes. If this is not provided, then a default length of 10 bytes will be used.
• "-C {chars}" or "--characterSet {chars}" -- specifies the set of characters that will be used to generate the values to use for the target attributes. It should only include ASCII characters. Values will be generated from randomly-selected characters from this set. If this is not provided, then a default set of lowercase alphabetic characters will be used.
• "-t {num}" or "--numThreads {num}" -- specifies the number of concurrent threads to use when performing the modifications. If this is not provided, then a default of one thread will be used.
• "-i {sec}" or "--intervalDuration {sec}" -- specifies the length of time in seconds between lines out output. If this is not provided, then a default interval duration of five seconds will be used.
• "-I {num}" or "--numIntervals {num}" -- specifies the maximum number of intervals for which to run. If this is not provided, then it will run forever.
• "--iterationsBeforeReconnect {num}" -- specifies the number of modify iterations that should be performed on a connection before that connection is closed and replaced with a newly-established (and authenticated, if appropriate) connection.
• "-r {modifies-per-second}" or "--ratePerSecond {modifies-per-second}" -- specifies the target number of modifies to perform per second. It is still necessary to specify a sufficient number of threads for achieving this rate. If this option is not provided, then the tool will run at the maximum rate for the specified number of threads.
• "--variableRateData {path}" -- specifies the path to a file containing information needed to allow the tool to vary the target rate over time. If this option is not provided, then the tool will either use a fixed target rate as specified by the "--ratePerSecond" argument, or it will run at the maximum rate.
• "--generateSampleRateFile {path}" -- specifies the path to a file to which sample data will be written illustrating and describing the format of the file expected to be used in conjunction with the "--variableRateData" argument.
• "--warmUpIntervals {num}" -- specifies the number of intervals to complete before beginning overall statistics collection.
• "--timestampFormat {format}" -- specifies the format to use for timestamps included before each output line. The format may be one of "none" (for no timestamps), "with-date" (to include both the date and the time), or "without-date" (to include only time time).
• "-Y {authzID}" or "--proxyAs {authzID}" -- Use the proxied authorization v2 control to request that the operation be processed using an alternate authorization identity. In this case, the bind DN should be that of a user that has permission to use this control. The authorization identity may be a value pattern.
• "--suppressErrorResultCodes" -- Indicates that information about the result codes for failed operations should not be displayed.
• "-c" or "--csv" -- Generate output in CSV format rather than a display-friendly format.

Returns:

true if this tool supports interactive mode, or false if not.

defaultsToInteractiveMode

public boolean defaultsToInteractiveMode()

Indicates whether this tool defaults to launching in interactive mode if the tool is invoked without any command-line arguments. This will only be used if supportsInteractiveMode() returns true.

Overrides:

defaultsToInteractiveMode in class CommandLineTool

Returns:

true if this tool defaults to using interactive mode if launched without any command-line arguments, or false if not.

supportsOutputFile

protected boolean supportsOutputFile()

Indicates whether this tool should provide arguments for redirecting output to a file. If this method returns true, then the tool will offer an "--outputFile" argument that will specify the path to a file to which all standard output and standard error content will be written, and it will also offer a "--teeToStandardOut" argument that can only be used if the "--outputFile" argument is present and will cause all output to be written to both the specified output file and to standard output.

Overrides:

supportsOutputFile in class CommandLineTool

Returns:

true if this tool should provide arguments for redirecting output to a file, or false if not.

defaultToPromptForBindPassword

protected boolean defaultToPromptForBindPassword()

Indicates whether this tool should default to interactively prompting for the bind password if a password is required but no argument was provided to indicate how to get the password.

Overrides:

defaultToPromptForBindPassword in class LDAPCommandLineTool

Returns:

true if this tool should default to interactively prompting for the bind password, or false if not.

supportsPropertiesFile

public boolean supportsPropertiesFile()

Indicates whether this tool supports the use of a properties file for specifying default values for arguments that aren't specified on the command line.

Overrides:

supportsPropertiesFile in class CommandLineTool

Returns:

true if this tool supports the use of a properties file for specifying default values for arguments that aren't specified on the command line, or false if not.

supportsDebugLogging

protected boolean supportsDebugLogging()

Indicates whether this tool supports the ability to generate a debug log file. If this method returns true, then the tool will expose additional arguments that can control debug logging.

Overrides:

supportsDebugLogging in class CommandLineTool

Returns:

true if this tool supports the ability to generate a debug log file, or false if not.

includeAlternateLongIdentifiers

protected boolean includeAlternateLongIdentifiers()

Indicates whether the LDAP-specific arguments should include alternate versions of all long identifiers that consist of multiple words so that they are available in both camelCase and dash-separated versions.

Overrides:
