Within Toad for Oracle 12.x connection process, this PL/SQL block is invoked.
-- Look for Team Coding synonym
FOR i IN syns.FIRST .. syns.LAST
LOOP
BEGIN
Select table_owner, table_name
INTO local_owner, local_table
FROM sys.ALL_SYNONYMS
WHERE owner = 'PUBLIC' AND synonym_name = syns (i);
In Toad for Oracle 12 executing this block causes a near three minute delay
We have installed the latest version of TOAD 12.8, and we have the same problem.
However, in Toad for Oracle 11, this block is not invoked. Thus, there is no delay.
