Re: dblink in PL/SQL block..

Edgar Chupit


Dear Onkar,

First of all to query dynamic performance views from remote
destination, you should grant your dblink user access to underlying
view/fixed table. In your case you should grant select on v_$session
and v_$sqltext_with_newlines to your dblink user. For example, suppose
that I have dblink trex_tt that will connect using user zulu

SQL> grant select on v_$session to zulu;
Grant succeeded

SQL> grant select on v_$sqltext_with_newlines to zulu;
Grant succeeded

After that you can run your queries to
v$session/v$sqltext_with_newlines to query from dblink.

Than after small changed in your code, it compiles and executes just
fine (I've changed line 14 and 25):
