Example
Remove an address from the load balance group named group_2.
=> SELECT * FROM LOAD_BALANCE_GROUPS; name | policy | filter | type | object_name ---------+------------+--------+-----------------------+------------- group_1 | ROUNDROBIN | | Network Address Group | node01 group_1 | ROUNDROBIN | | Network Address Group | node02 group_2 | ROUNDROBIN | | Network Address Group | node03 (3 rows) => ALTER LOAD BALANCE GROUP group_2 DROP ADDRESS node03; ALTER LOAD BALANCE GROUP => SELECT * FROM LOAD_BALANCE_GROUPS; name | policy | filter | type | object_name ---------+------------+--------+-----------------------+------------- group_1 | ROUNDROBIN | | Network Address Group | node01 group_1 | ROUNDROBIN | | Network Address Group | node02 group_2 | ROUNDROBIN | | Empty Group | (3 rows)
The following example adds three network addresses to the group named group_2:
=> ALTER LOAD BALANCE GROUP group_2 ADD ADDRESS node01,node02,node03; ALTER LOAD BALANCE GROUP => SELECT * FROM load_balance_groups WHERE name = 'group_2'; -[ RECORD 1 ]---------------------- name | group_2 policy | ROUNDROBIN filter | type | Network Address Group object_name | node01 -[ RECORD 2 ]---------------------- name | group_2 policy | ROUNDROBIN filter | type | Network Address Group object_name | node02 -[ RECORD 3 ]---------------------- name | group_2 policy | ROUNDROBIN filter | type | Network Address Group object_name | node03
