Elements and Attributes of the wtc_config.dtd

The following sections contain reference information on the elements and attributes contained in the wtc_config.dtd:

• WTC_CONFIG

• BDMCONFIG

• tBridge

WTC_CONFIG

WTC_CONFIG is the root of the WebLogic Tuxedo Connector deployment descriptor. WTC_CONFIG has two children:

• BDMCONFIG

• tBridge

BDMCONFIG

The BDMCONFIG element provides information on how to configure domains in the WebLogic Tuxedo Connector. The configuration parameters are analogous to the DM_MIB attributes and classes used for Tuxedo domains.

T_DM_LOCAL_TDOMAIN

The T_DM_LOCAL_DOMAIN provides a view of local domains as they appears to other domains.

WlsClusterName

Note: Although WebLogic Tuxedo Connector does not support clustering in this release of WebLogic Server, you must provide a WlsClusterName.

Required. WlsClusterName gives the name of the WebLogic Server cluster in the WSL domain on which this local access point resides.

Example: cluster20

AccessPointId

Required. Specifies the connection principal name used to identify a domain when establishing a connection to another domain.

• The AccessPointId of a T_DM_LOCAL_TDOMAIN must match the corresponding DOMAINID in the *DM_REMOTE_DOMAINS section of your Tuxedo DMCONFIG file.

• The AccessPointId of a T_DM_REMOTE_TDOMAIN must match the corresponding DOMAINID in the *DM_LOCAL_DOMAINS section of your Tuxedo DMCONFIG file.

Example: TDOM2

Type

Optional. If specified the value must be the string TDOMAIN.

Security

Note: Tuxedo 6.5 users should set the security parameter to NONE.

Optional. Security specifies the type of application security to be enforced. Valid values for this parameter are: NONE, APP_PW, or DM_PW.

• NONE: No security is used. This is the default value.

• APP_PW: Password security is enforced when a connection is established from a remote domain. The application password must be defined in a T_DM_PASSWORD element.

• DM_PW: Domain password security is enforced when a connection is established from a remote domain. Domain passwords must be defined in the T_DM_PASSWORD element.

ConnectionPolicy

Optional. Specifies the conditions under which a local domain tries to establish a connection to a remote domain.

• Valid values for local domains are: ON_DEMAND, ON_STARTUP, or INCOMING_ONLY.

• Valid values for remote domains are: ON_DEMAND, ON_STARTUP, INCOMING_ONLY, or LOCAL.

• Default setting is ON_DEMAND

  • ON_DEMAND: A connection is attempted only when requested by either a client request to a remote service or an administrative connect command.

  • ON_STARTUP: A domain gateway attempts to establish a connection with its remote domain access points at gateway server initialization time. Remote services (services advertised in JNDI by the domain gateway for this local access point) are advertised only if a connection is successfully established to that remote domain access point. If there is no active connection to a remote domain access point, then the remote services are suspended. By default, this connection policy retries failed connections every 60 seconds. Use the MaxRetry and RetryInterval elements to specify application specific values.

  • INCOMING_ONLY: A domain gateway does not attempt an initial connection to remote domain access points at startup and remote services are initially suspended. The domain gateway is available for incoming connections from remote domain access points and remote services are advertised when the domain gateway for this local domain access point receives an incoming connection. Connection retry processing is not allowed.

  • LOCAL: Indicates the remote domain connection policy is explicitly defaulted to the local domain ConnectionPolicy attribute value. If the remote domain ConnectionPolicy is not defined, the system uses the setting specified by the associated local domain (specified by the LocalAccessPoint).

RetryInterval

Optional. The time (seconds) between automatic attempts to establish a connection to remote domain access points. Use only when ConnectionPolicy is set to ON_STARTUP.

• Minimum value: 0

• Maximum value: 2147483647

• Default setting: 60

MaxRetries

Optional. The number of times that a domain gateway tries to establish connections to remote domain access points. Use only when ConnectionPolicy is set to ON_STARTUP.

• Minimum value: 0

• Maximum value: 2147483647.

• Default value: 2147483647

Use the maximum value to retry processing until a connection is established. Use the minimum value to disable the automatic retry mechanism.

ConnPrincipalName

Note: ConnPrincipalName is not supported in this release of WebLogic Server.

Optional. Specifies the connection principal name identifier. This is the principal name for identifying a domain when establishing a connection to another domain. This parameter only applies to domains of type TDOMAIN that are running BEA Tuxedo 7.1 or later software.

• If this element is not specified, the connection principal name defaults to the AccessPoint element for this domain.

NWAddr

Note: When configuring the NWAddr for a T_DM_LOCAL_DOMAIN, the port number used should be different from any port numbers assigned to other WebLogic Server processes. Example: Setting the NWAddr to //mymachine:7001 is not valid if the WebLogic Server listening port is assigned to //mymachine:7001.

Required. The network address of the local domain gateway. Specify the TCP/IP address in one of the following formats:

• //hostname:port_number

• //#.#.#.#:port_number

If hostname is used, the domain finds an address for hostname using the local name resolution facilities (usually DNS). If dotted decimal format is used, each # should be a number from 0 to 255. This dotted decimal number represents the IP address of the local machine. The port_number is the TCP port number at which the domain process listens for incoming requests.

CmpLimit

Optional. Specifies the compression threshold used when sending data to the remote domain. Application buffers larger than this size are compressed.

• Default value: 2147483647 bytes

MinEncryptBits

Note: A MinEncryptBits value of 40 only applies to domains of type TDOMAIN that are running BEA Tuxedo 7.1 or later software.

Optional. Specifies the minimum level encryption key length (in bits) used when establishing a network link for this domain.Valid values for this parameter are: 0, 40, 56, and 128.

• Default value: 0 bits

• A value of 0: No encryption used

• If this minimum level of encryption cannot be met, the network link fails.

MaxEncryptBits

Note: A MaxEncryptBits value of 40 only applies to domains of type TDOMAIN that are running BEA Tuxedo 7.1 or higher.

Optional. Specifies the maximum level encryption key length (in bits) used when establishing a network link for this domain.Valid values for this parameter are: 0, 40, 56, and 128.

• Default value: 128 bits

• A value of 0: No encryption used

Interoperate

Note: Optional. Specifies whether the local domain interoperates with remote domains that are based upon Tuxedo Release 6.5. Tuxedo 6.5 does not have the required security infrastructure to support security mapping. If you require security features and use the WebLogic Tuxedo Connector, you will need to upgrade to Tuxedo 7.1 or higher.

Valid values for this parameter are: Yes, No.

• Yes: Interoperate with Tuxedo 6.5

• No: Operates with domains Tuxedo 7.1 and higher.

• Default value: No

BlockTime

Optional. Specifies the maximum wait time (seconds) allowed for a blocking call.

T_DM_REMOTE_TDOMAIN

Optional. Specifies the inbound access control list (ACL) policy toward requests from a remote domain. Valid values for this parameter are: LOCAL, GLOBAL.

• LOCAL: The local domain modifies the identity of the service requests received from a given remote domain to the principal name specified in the local principal name for a given remote domain.

• GLOBAL: The local domain passes the service request with no change in identity.

• Default value: LOCAL

CredentialPolicy

Note: If the Interperate parameter is set to Yes, the CredentialPolicy is ignored. For more information see, Interoperate.

Optional. Specifies the outbound access control list (ACL) policy toward requests to a remote domain. Valid values for this parameter are: LOCAL, GLOBAL.

• LOCAL: The remote domain controls the identity of service requests received from the local domain to the principal name specified in the local principal name for this remote domain.

• GLOBAL: The remote domain passes the service request with no change.

• Default value: LOCAL

FederationURL

The URL for a foreign name service that is federated into the JNDI.

If ommitted, the WebLogic Tuxedo Connector assumes that there is a CosNaming server in the foreign domain. The WebLogic Tuxedo Connector federates to the CosNaming server using TGIOP. It is possible to federate to non-CORBA service providers.

FederationName

The context at which to federate to a foreign name service. If ommitted, the federation point is tuxedo.domains.

TpUsrFile

Optional. Full path to user password file containing uid/gid information. This is the same file generated by the Tuxedo tpusradd utility on the remote domain. Username, uid and gid information must be included and valid for correct authorization, authentication, and auditing.

T_DM_EXPORT

T_DM_EXPORT provides information on services exported by a local domain.

• If not specified, all local domains accept requests to all of the services according to the default JNDI lookup rules (see EJBName).

T_DM_IMPORT

The T_DM_IMPORT provides information on services imported and available on remote domains. If T_DM_IMPORT is not configured, remote domains handle all remote services.

TranTime

Note: TranTime is not supported for this release of WebLogic Tuxedo Connector.

Optional. Specifies the default timeout value (seconds) for a transaction started in an associated service. It is the total time from the start of a transaction through the execution of the rollback or commit. 0 implies the maximum timeout value.

• Minimum value: 0

• Default value: 30

T_DM_PASSWORD

The T_DM_PASSWORD class represents configuration information for inter-domain authentication through access points of type TDOMAIN.

LocalPassword

Required. The encrypted local password as returned from the genpasswd utility. This password is used to authenticate connections between the local domain access point identified by LocalAccessPoint and the remote domain access point identified by RemoteAccessPoint.

RemotePassword

Optional. Specifies the exp_time (seconds) for a message being redirected into Tuxedo from WebLogic Server if the JMSExpiration property is not set.

It is not possible to get the expiration time from a Tuxedo/Q message. Use defaultRelativeExpiration to set an expiration time for messages being redirected to Tuxedo/Q.)

expirationAdjustment

Note: This element is not supported in this release of WebLogic Tuxedo Connector.

Optional. Specifies the amount of time (seconds) that is added to the expiration time of a message before it is put onto the target location.

• This value is added to the expiration time when the expiration time for a message is non-zero prior to being retrieved from the source location.

• Use this adjustment to account for any network or processing latency incurred as a result of using the tBridge.

priorityMapping

Required. Provides a method to map the priorities between the JMS and Tuxedo.

• JMS has ten priorities (0 - 9).

• Tuxedo/Q has 100 priorities (1 - 100).

The priorityMapping section provides a mechanism to map the priorities between the Tuxedo and JMS subsystems. There are two mapping directions:
