RE: Is it possible to do "select count(*) from sapr3.zpayr@QA2;"

I would generally keep the database link around if you think you may want to use it again in the future. It's not going to consume an appreciable amount of resources if no one is using it.

Cool. It works.
So do I need to do "delete database link qa2" to clean up?
Thanks.

While connected to pr2:
create database link qa2 connect to system identified by manager using 'qa2';

That's one option. There are other variations on database links. See the
manual for more details.

You need a database link created between PR2 and QA2.

Subject: Is it possible to do "select count(*) from sapr3.zpayr@(protected);"

>From SID=PR2, I failed to do the following:

SQL> select count(*) from sapr3.zpayr@(protected);
select count(*) from sapr3.zpayr@(protected)
                     *
ERROR at line 1:
ORA-02019: connection description for remote database not found




But I can do the following without any problems:

sqlplus system@(protected)
SQL> select count(*) from sapr3.zpayr;





Thanks,

Roger
