Re: connect through java using group_name con mgr

Posted By: PING TANG
Date: Wednesday, 22 April 2009, at 5:40 p.m.

In Response To: connect through java using group_name con mgr (KAMRAN HAQ)

Kamran:

If you want to access all nodes as a group, you could modify and add a mach_group to the oncmsm's sqlhosts as below.

g_mach group - - e=ids_net_RSS
ids_net_primary ontlitcp 192.168.0.16 sql_net_primary g=g_mach
ids_net_secondary ontlitcp 192.168.0.15 sql_net_secondary g=g_mach
ids_net_RSS ontlitcp 192.168.0.14 sql_net_RSS g=g_mach
mach_group group - - e=payroll <==
oltp onsoctcp 192.168.0.16 9991 g=mach_group <==
report onsoctcp 192.168.0.16 9992 g=mach_group <==
payroll onsoctcp 192.168.0.16 9993 g=mach_group <==
