xdbappc.ini Parameters

Restriction: This topic applies to Windows environments only.

The following table describes the parameters used by xdbappc.ini.

PU Definition Section

Parameter	Description
PU	Physical Unit name. This parameter must match the entry in the CSCON profile named "Peripheral CP Name."
Profile	Profile name. This name must match the name of the profile configured with CSCON and loaded with CSLOAD.
Network	Network Identifier. This parameter must match the entry in the CSCON profile named "SNA Network ID."
LuName	Logical Unit Name. This is the LU name configured on the host that identifies this computer.
LuAlias	Logical Unit Alias Name. This is the name of the LU as it will be known locally. We recommend that you use the XDB Server name as the alias.
LocAddr	LU local address. This address must be 0 for independent LUs.
SessionLimit	LU Session Limit. This value specifies the number of sessions this LU can have with the host. The value should be less than or equal to the entry in the CSCON profile named "Independent Sessions."
MaxTPs	Maximum Transaction Program Limit. This entry indicates the number of transaction programs that can use this LU. It should be less than or equal to the session limit above. Each user connected through XDB Link gets an individual session and TP, so MaxTPs represents the maximum XDB Link connections possible with the host.
QueueDepth	Depth of incoming allocate queue. This is the number of allocate requests that can be in the queue, waiting to be serviced by this LU.
PLU	Partner Logical Unit Name. This specifies the remote database as it is known to the SNA network. For MVS/VTAM, this is the VTAM DB2 APPLID name.
Network ID	Network Identifier. This is the name of the SNA network to which the partner LU belongs. This allows for a fully-qualified partner LU name.
Alias	Partner Logical Unit Alias. This is the name of the partner LU as it will be known locally. The value of this parameter is used by the Gateway Profile Utility to identify the remote database.
Security	Partner Logical Unit Security Capabilities. 1 = Already Verified 2 = Conversation Level security 4 = Session Level security 128 = Activate link to PLU at Attach LU time Combinations of security capabilities can be added together. For Example: 3 is Conversation Level security and Already Verified (1 OR 2).
SessionLimit	Partner Logical Unit Session Limit. This entry is the maximum number of sessions for which this partner is configured.
MaxMcSendLL	Maximum Mapped Conversation Send Logical Length. Maximum size of data to send on a mapped conversation. The value 0 means use the largest possible value (32767).
DlcName	Data Link Control Name. This entry identifies the connection type to the host system. Possible values are: SDLC - Synchronous Data Link Control ITRN - Token Ring or Ethernet QLLC - Qllc connection CUSTOM - Custom connection
AdaptNum	Adapter Number. Indicates which adapter to use. For Token Ring use 0 to indicate the Primary adapter or 1 to indicate the Secondary adapter. All other DLCs should use 0.
AdaptAddr	Adapter address: SDLC - Omit this entry for this DLC type. It is not used. ITRN - This is a 12-digit hexadecimal value of the locally administered address of a front-end processor (3174/37X5, PC gateway, etc.). QLLC - Target name of the record in the call support layer (CSL) database defined in the NWSAA server. This entry can be up to 16 ASCII characters in length. CUSTOM - Symbolic name used by the custom data link adapter. This entry can be up to 16 ASCII characters in length.
ModeName	Mode Name. This entry is used to identify which mode definition to use for this partner LU.

Mode Definition Section

Parameter	Description
Mode	The Mode Name. The name of the mode to use for setting up sessions between the Local LU and the Partner LU. The recommended value is IBMRDB.
MaxRu	Maximum Request/Response Unit. The maximum size (in bytes) of a Request/Response Unit.
MinRu	Minimum Request/Response Unit. The minimum size (in bytes) of a Request/Response Unit.
MaxNegotiable	The Maximum Negotiable Session Limit. This value is used to override the PLU max session limit.
Pacing	Pacing Limit. The maximum number of Request/Response Units allowed before confirmation between LU and PLU.
