Schedule Object Server Policy Group

The DSM Explorer › Control Panel › Configuration Folder › Configuration Policy › Default Computer Policy (or User-Defined Policy) Node › Data Transport Service (DTS) Policy Group › Schedule Object Server Policy Group

The Schedule Object Server policy group contains the following policies for the DTS Schedule Object Server (SOS). You can modify policy parameter values by double-clicking a policy to display the Setting Properties dialog.

Note: The Transfer Object Server (TOS), Network Object Server (NOS), and Schedule Object Server are commonly referred to as object servers, DTS servers, and servers throughout the documentation. However, in formal DSM terminology, they are DTS managers.

Cache flush interval

Specifies the number of seconds after which the server process writes all unsaved object information to disk, that is, the periodic flushing of the object cache. If 0 is specified, data is written to disk immediately after an update operation is performed by the servers.

Limits: 0–10000000

Default: 60

Cache size

Specifies the maximum number of objects that can be held in the server's memory cache. Caching can significantly improve the performance of the server for which you are setting the cache size. It is most advantageous in situations where repeated transfers between the same computers are common. Valid values are 0 and higher. A value of 0 disables caching; all object updates are immediately flushed to disk.

Note: When setting this policy, keep in mind the amount of memory that the server process consumes. Cache is not preallocated and therefore grows to its maximum size as the server is used. The cache-size value simply limits the cache to a maximum number of objects.

Limits: 0–10000000

Default: 1024

Enable legacy manager communication

Indicates that this component must connect to a legacy manager component, if True.

Default: False

Enable SOS auditing

Enables auditing by the domain manager, if True.

Default: True

Incoming connection timeout

Specifies the number of seconds of client inactivity that must pass before the client is automatically disconnected by the server.

Limits: 60–36000

Default: 300

Maximum number of incoming connections

Specifies the maximum number of clients that can be connected at one time.

Limits: 1–1000

Note: A limit lower than the one you specify here may be imposed by the operating system.

Default: 64

Security mode

Determines whether incoming transfer requests must be authenticated. Responses to security violations are dependent on the current security mode. Valid values are as follows:

quiet: Disables security checking.
warn: Enables security checking. If an invalid request is detected, the operation is permitted to continue. However, the violation is recorded in the log file to indicate the occurrence.
fail: Enables security checking. If an invalid request is detected, the operation is immediately aborted. When fail mode is enabled, users are required to enter a valid user name and password before they are able to display or set the runtime parameters for any of the DTS computers.

Default: fail

SOS protocol parameters

Specifies the port used to listen for legacy TCP requests.

Default: RPORT=<8200>

TOS network address

Specifies the DTS Transfer Object Server to which the Schedule Object Server connects. You can specify either the name of the TOS or the network address. By default, this policy is set to the address of the computer on which the SOS is installed.

Default: localhost

TOS protocol parameters

Specifies the protocol parameters to use when connecting to a legacy DTS r1, r2, or r3 Transfer Object Server.

Default: IPORT=<8198>
