UC_HOSTCHAR_DEFAULT - Host Characteristics

This Variable (VARA) object contains default agent settings and it is supplied with system client 0000. You can copy this variable and rename it to UC_HOSTCHAR_<SUFFIX> to define specific agent settings.

Notes:

• In the variable UC_EX_HOSTCHAR, you can assign only one variable with the same suffix to each agent, see UC_EX_HOSTCHAR - Assigning Agents to Host Characteristics
• Due to performance reasons, changes in UC_EX_HOSTCHAR and UC_HOSTCHAR_DEFAULT take up to one minute to take effect. These variables are cached and refreshed every minute.
• The column FT Protocol in the respective key indicates whether the file transfer settings apply for the old and/or the new protocol. For more information, see Secure File Transfer Protocol.

ANONYMOUS_FE, ANONYMOUS_FT, ANONYMOUS_JOB

Important! The keys ANONYMOUS_FE (file events), ANONYMOUS_FT (file transfers), and ANONYMOUS_JOB (jobs) are only supported for OS/400, UNIX and Windows agents.

• Description: These settings can be used to define whether the login credentials that are stored in the Login (LOGIN) object have to be used to execute jobs, file events, and file transfers, respectively. The behavior also depends on the settings that are defined in the following INI file parameters of the agent:

• Allowed values: Y and N

• Default value: N

• Restart required: Agent

  For more information, see Working with Agents.

• FT Protocol Old and new

The behavior of these keys also depends on the settings that are defined in the parameter[GLOBAL] in the INI file of each agent:

Windows

• logon=0

  The login data that is stored in the Login object is not used. The job, file event, and/or file transfer runs under the user of the agent's OS.
  
  

• logon=1

  The Login object is used.

UNIX

• login_check=no

  The job, file event, and/or file transfer runs with the user of the OS that is stored in the Login object. Passwords are not checked.

  Requirement: The agent must run under a privileged user.

  Note: If the UNIX agent runs under a non-privileged user, the agent can start jobs only with the user who started the agent itself. For this purpose, the agent must also run in anonymous mode (login_check=no and ANONYMOUS_*=Y).

• login_check=yes

  The Login object is used.

OS/400

• CheckLogon=0

  The job, file event, and/or file transfer runs with the user of the OS that is stored in the Login object. Passwords are not checked.

  Requirement: The agent must run under a privileged user.

• CheckLogon=1

  The Login object is used.

Important! Regardless of the agent's OS, it is recommended using the Login object.

You also have to set the privilege Start without Login object specified in the Users object. For more information, see Users (USER).

• File Transfers (JOBF)

  With this privilege, file transfers can be executed without Login objects. Such file transfers are executed under the user of the agent's OS.

  Requirements:

  Windows: ANONYMOUS_FT=Y and logon=0

  UNIX: login_check=no

• FILE Events

  With this privilege, file events can be executed without Login objects. Such e file events are executed under the user of the agent's OS. ANONYMOUS_FE and configuration file parameters such as logon (Windows), login_check (UNIX), or check_logon (OS/400) are ignored.

• Users (USER)

  There is no privilege available in the User object that allows to start jobs without a Login object. Therefore, even if you define ANONYMOUS_JOB=Y, jobs without Login objects abort.

APPLICATION_LOGIN

• Description: Name of a Login object

  The login data of the Login (LOGIN) object is used for the following purposes:

  • PS agents: Login data for PeopleSoft

  • Windows and UNIX agents: Email connection through SMTP

• Default value: ERP_LOGIN

• Restart required: Agent

  For more information, see Working with Agents.

• Description: Time of day at which the backup folder's lifetime is checked

  All files and directories that are older than the value defined in the key BACKUP_RETENTION_LIFETIMEare deleted.

  Notes:

  • The backup folder stores the files of the file rollback of jobs and file transfers. You can define the backup folder using the agent variable UC_EX_PATH_BACKUP in the INI File of the agent. for more information, see List of Agent Variables.

  • In the Rollback page, you can specify the files that must be copied to the backup folder. They are stored automatically when a Job object or File Transfer object is processed.

• Allowed values: Valid time

• Format: HH:MM:SS

• Default value: 00:00:00

• Restart required: Agent

  For more information, see Working with Agents.

BACKUP_RETENTION_LIFETIME

Important! This key affects only Windows and UNIX agents.

• Description: Life time in days for the content of the backup folder

  With this key, you can determine how long files and directories are kept in the backup folder. The system checks this setting daily at the time that is specified in the key BACKUP_RETENTION_CHECK. Contents older than the value defined are deleted.

• Allowed values: 0 to 99

• Default value: 14

• Restart required: Agent

  For more information, see Working with Agents.

DISCONNECT_AFTER_FT

• Description: Defines whether the connection between the agents ends after a File transfer, see File Transfers (JOBF)

  This key only affects the connection but not the execution of the file transfer. The system always checks whether there is a connection to the destination agent before the file transfer starts. A connection is established if it is not available.

• Allowed values: YES and NO

• Default value: YES

• Restart required: Agent

  For more information, see Working with Agents.

• FT Protocol Old

  This setting is checked only if you use the old file transfer protocol. Using the new protocol means that the connection is always automatically terminated.

EVENT_CHECKINTERVAL

• Description: Time interval in seconds in which the agent checks the conditions FILE_CHANGED and FILE_STABLE in its File events, see FILE Events.

  Note: If you select FILE_CHANGED or FILE_STABLE in a file event, this interval is used for all condition checks. The interval increases automatically if the check of a condition takes longer than the specified interval.

• Allowed values: 60 - 100000

• Default value: 60

• Restart required: Agent

  For more information, see Working with Agents.

EXECUTE_ON_START, EXECUTE_ON_END, EXECUTE_ON_LOST, EXECUTE_ON_ASSIGNMENT

FT_ASYNC_QUIT_MAX, FT_ASYNC_QUIT_MIN, FT_ASYNC_QUIT_NUM

Important! This keys are available only for OS/400, NSK, Windows, UNIX and z/OS agents.

• Description: These keys define the settings for synchronous and asynchronous (default) transfers between a sending and a receiving agent of file transfers

  • FT_ASYNC_QUIT_MAX

    Maximum number of non-confirmed data packages that the sender sends to the receiving agent

    Allowed values: 1 - 100

    Default value: 60

  • FT_ASYNC_QUIT_MIN

    Minimum number of non-confirmed data packages that the sender sends to the receiving agent

    Allowed values: 0 - 50

    The value defined here cannot exceed the value defined in FT_ASYNC_QUIT_MAX.

    Default value: 30

  • FT_ASYNC_QUIT_NUM

    Number of data packages that are confirmed per receipt

    Allowed values: 1 - 50

    Default value: 5

  Note: The higher the value of FT_ASYNC_QUIT_MIN, the better the agent performs when FT_ASYNC_QUIT_MAX is reached.

• Restart required: No

• FT Protocol New

Synchronous transfer: Data packages are only sent when the receipt of sent packages is confirmed. The sending and receiving agents adjust their transmission speeds.

You have a synchronous behavior when the setting of the key FT_ASYNC_QUIT_NUM equals the setting of the key FT_ASYNC_QUIT_MAX.

Example

• FT_ASYNC_QUIT_MIN: 0

• FT_ASYNC_QUIT_MAX: 1

• FT_ASYNC_QUIT_NUM: 1

Asynchronous transfer: Data packages are sent although no confirmation is received. This allows data to be transferred faster because the connections (faster or slower) are used more efficiently. The TCP/IP buffer of the agent must be increased accordingly using the parameters SendBufferSize= and RecvBufferSize= in the INI file of the agent.

You have an asynchronous behavior when the setting of the key FT_ASYNC_QUIT_MAX is a multiple of the setting of the key FT_ASYNC_QUIT_NUM.

Examples

Weak asynchronous transfer:

• FT_ASYNC_QUIT_MIN: 0

• FT_ASYNC_QUIT_MAX: 10

• FT_ASYNC_QUIT_NUM: 5

The sending agent may send a maximum of 10 non-confirmed data packages. If the maximum has been reached, it waits until all receipts have been confirmed before it continues the sending process.

Strong asynchronous transfer:

• FT_ASYNC_QUIT_MIN: 30

• FT_ASYNC_QUIT_MAX: 60

• FT_ASYNC_QUIT_NUM: 5

The sending agent may send a maximum of 60 non-confirmed data packages. Receipts are confirmed each 5 packages. The sending agent always waits until 30 non-confirmed data packages are open before it starts the data transfer.

  • N: The agent does not send log messages to the Automation Engine. This setting improves the Automation Engine system's performance.

• Default value: Y

• Restart required: Agent

  For more information, see Working with Agents.

MAX_FILE_COUNT

• Description: Maximum number of files that are considered in File events, see FILE Events

  If wildcard characters are used or sub-directories are included in the search, a large number of files can be found during the checks. For performance reasons, you can specify a maximum number of files that are considered. The agent checks files only up to this number. It check whether the specified condition applies and, if applicable, triggers the contents of the Event Process page.

  This definition results in a maximum report size of 937 KB.

  After job execution, a job report can be stored locally in the file system and/or can be transferred to the Automation Engine which then stores it in its database. This is defined in the agent-specific page of the job. If a report has to be transferred to the Automation Engine, the settings of the keys REPORT_BLKSIZE and MAX_REPORT_SIZE apply. The report is truncated if it exceeds the maximum number of blocks. In this case, an incomplete report is stored in the database.

  Notes:

  • If the Job report are stored in the database, the file is deleted on the file system once it has successfully been transferred.

  • If the Job report is stored in a file, the settings defined in the keys REPORT_BLKSIZE and MAX_REPORT_SIZE are not considered. In this case, the complete report is stored in the file system. For more information, see Job Reports.
