tnsping query
I am going to do the following
tnsping "(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=uservername)(PORT=1521)))(CONNECT_DATA=(SID=test)(server=DEDICATED)))"
What even I put sid to any other name ie testa, testb ( which dont exist in the database). the tnsping results still OK . As long as the servername and port is correct
I would like to know if tnsping can check if the instance is really up and running ?
