AW: How to create two db-links within one schema when global_names=trNirmal,

When the instance starts up both have same information. If you set a session's value using ALTER SESSION SET <someparameter> = <somenewvalue> then the newvalue is shown in V$PARAMETER but not in V$SYSTEM_PARAMETER.

for instance

SQL> select value from v$parameter where name = 'sort_area_size';

VALUE

1024000

1 row selected.

SQL> select value from v$system_parameter where name = 'sort_area_size';

VALUE

1024000

1 row selected.

SQL> alter session set sort_area_size = 1024;

Session altered.

SQL> select value from v$parameter where name = 'sort_area_size';

VALUE

1024

1 row selected.

SQL> select value from v$system_parameter where name = 'sort_area_size';

VALUE

1024000

1 row selected.

Hi,

Where these two, V$SYSTEM_PARAMETER, V$PARAMETER dynamic view are differs?

Both of them looks the same in structure and data as well.

Anybody have any idea.

Nirmal.

Hi Jonathan,

thanks for your reply.

The deal is that you can't use DB1_at_HR and DB1_at_SHIP if you are using global_names=true; the link name has to be the same than the global database name.

But what do I do, if I need the same user to have two db-links to different schemas on the remote database?

Any idea?

Thanks,
Helmut

Look up the details of 'connection qualifiers'.

create public database link DB1_at_HR

connect to hr identified by pwd_hr using 'DB1';

create public database link DB1_at_SHIP

connect to shipping identified by pwd_shipping using 'DB1';
