it say that in that is a protocol error!
Answers:
Could be a couple things.
You might hold 2 databases on that server, so you hold to specify which database you want to connect to. Say, for example, you one database call ORCL and the other call CSI (watching CSI in a minute, so for insufficiency of a better signature :-)
So from directly on that server, do:
cmd>set ORACLE_SID=ORCL
cmd>svrmgrl
SVRMGR>connect internal
password: oracle
Of course replace the password next to the actual password. If your database contained by on Linux or Unix, replace
cmd>set ORACLE_SID
with
$export ORACLE_SID=ORCL
If you needed to connect to database CSI, consequently directly on the database server do:
$export ORACLE_SID=CSI
or
cmd>set ORACLE_SID=CSI
Another scenario, could be that your listener isn't started. Either start it contained by the Services Panel on window or from the command row (DOS or shell) resembling this
$lsnrctl start
Or if you're connecting over the introduce yourself, which will be using the tnsnames.ora wallet, you'll enjoy to specify the database to which you want to connect to:
SQL>connect username/password@ORCL
or
SQL>connect username/password@CSI
Hope this help :-)
