Hi,

Can anyone help me to understand below elements in DB connection in datastage

$DB2_CLIENT_INSTANCE_NAME
$APT_DB2INSTANCE_HOME
$DB2_SERVER
$DB2_DATABASE

How all are different from one another.While database connection in a job, how all these perform in which order?

Thanks

Hi Subrat,

$DB2_CLIENT_INSTANCE_NAME : db2lcnt
$APT_DB2INSTANCE_HOME: path ex: (/home/db2home/db2clnt)
$DB2_SERVER: Server where the database has been installed
$DB2_DATABASE:(This prob sid(system identification Number)

When u connect from client machine
Client spans,Serches the server,finds the home,in that find which instance to be connected
