Hi,
I have two production databases running on Veritas Cluster Server. the two databases can connect to each other. Since last Tuesday, it stopped working for connecting from one to the other. When I do tnsping SID, it shows
Attempting to contact (ADDRESS=(PROTOCOL=TCP)(HOST=hubdb)(PORT=1521))
TNS-12541: TNS:no listener

But when I go to the other database and do a lsnrctl status, it shows listener is working and I can connect from another server to this database too. I went to ask my SA if he made any changes to the database and he said no changes were made to the database. From tnsping, it only shows TNS-12541 error.
Can anyone help me with this? Thanks in advance.
