v1ST_CONN, the ®rst database that a connection is established to will be used as the Transaction Manager database for transactions. If this option is used, then the ®rst database connected to must be either a DB2 Universal Database Version 5 or later database, or a DB2 Universal Database for OS/390 Version 5.1 or later database. This is the recommended setting, and it is the default value for TM_DATABASE.

vdatabase_name, the named database that is connected to will be used. If this option is used, we recommend that the named database should be either a DB2 Universal Database version 5 or later database, or a DB2 Universal Database for OS/390 Version 5.1 or later database.

Update the DB2 Connect Directories:

1.At a command line prompt, issue the following command to catalog the DB2 for MVS/ESA node:

db2 catalog tcpip node MVSIPNOD remote MVSHOST server db2inst1c where:

vMVSIPNOD is the local DB2 Connect node name to be used for the host.

vMVSHOST is the eight-character TCP/IP host name for the DB2 Universal Database for OS/390 host. TCP/IP name lookup must resolve

this name to the correct destination Internet address, either through an entry in the local hosts ®le on the DB2 Connect workstation, or via a Domain Name Server (DNS) referenced by the DB2 Connect workstation.

vdb2inst1c is the port number de®ned at the DB2 Connect workstation. This must resolve to the same port number as that de®ned for use by DB2 Connect at the DB2 for MVS/ESA host. Alternatively, you can specify the service name associated with that port.

2.Create entries for the Database and Data Connection Services directories, as follows (this shows the values used in the sample worksheet):

db2 catalog dcs database NYC3 as NEW_YORK3

db2 catalog database NYC3 as MVSIPDB1 at node MVSIPNOD authentication dcs

where:

vMVSIPDB1 is user-de®ned and represents the DB2 Connect database alias for the host database.

vNYC3 is the DB2 Connect database name for the host database.

vMVSIPNOD is the DB2 Connect node name for the host.

vNEW_YORK3 is the DB2 Universal Database for OS/390 LOCATION NAME for the target database.
