GWTOPEND - TOP END Domain Gateway process

GWTOPEND SRVGRP = "identifier" SRVID = "number" RQADDR = "queue_name"
REPLYQ = N RESTART = Y [MAXGEN = value] [GRACE = value]

GWTOPEND is the domain gateway process that provides communication between a BEA Tuxedo domain and a BEA TOP END system. GWTOPEND gateway processes communicate with the Network Interface (NI) component on one or more nodes of a single BEA TOP END system. Different GWTOPEND gateways (in different BEA Tuxedo groups) may be configured to access different BEA TOP END systems or to split the load. GWTOPEND supports request/reply, pseudo-conversations, queuing, and transactions.

Domain gateways are described in the SERVERS section of the UBBCONFIG file and the BDMCONFIG file. Domain gateways must be associated with a particular group, that is, SRVGRP must be set to the corresponding GRPNAME tag specified in the GROUPS section.

The SVRID parameter is also required and its value must specify the maximum number of gateways allowed within the domain group. The RESTART parameter should be set to Y. The REPLYQ parameter should be set to N.

The GWTOPEND process must be in the same group as the GWADM(5) process, with the GWADM listed first. Multiple GWTOPEND processes can be configured for a domain; each must be configured in a different BEA Tuxedo group.

If BEA TOP END security is configured for the gateway, the BEA TOP END Security Services product must be installed on the node and the srvtab file for the TP_SYSTEM name must be copied to the node in the location shown in the "Files" section. If long node names are to be supported, the nodemap file must be copied to the node in the location shown in the "Files" section.

$TUXDIR/udataobj/nodemap

$APPDIR/srvtab.system (where system is the BEA TOP END system name)

/usr/lib/libtp_krb.so (installed on UNIX platforms on which BEA TOP END security is configured)

%TOPENDDIR%\bin\krb.dll (installed on Windows NT platforms on which BEA TOP END security is configured)

The following example shows the definition of a domain gateway group in the UBBCONFIG file.

*GROUPS 
DMADMGRP LMID=mach1 GRPNO=1
gwgrp  LMID=mach1 GRPNO=2 
*SERVERS 
DMADM SRVGRP="DMADMGRP" SRVID=1001 REPLYQ=N RESTART=Y MAXGEN=5   GRACE=3600
GWADM SRVGRP="gwgrp" SRVID=1002 REPLYQ=N RESTART=Y MAXGEN=5   GRACE=3600
GWTOPEND SRVGRP="gwgrp" SRVID=1003 RQADDR="gwgrp" REPLYQ=N 	 RESTART=Y MAXGEN=5 GRACE=3600

See the "Examples" section of UBBCONFIG(5) and DMCONFIG for GWTOPEND(5) for additional information.
