""when i'm trying to connect with sql*plus by specifying username,password and host string its showing me error
ora-12154 tns: could not resolve the connect identifier specified""
that is what we want to see as copy nad paste ?
how did you do it?
and have you sat the oracle_sid and oracle_home too?
as you may have more than one home or more tha one SID
Yes sir, i have multiple oracle databases on my system. but i can set ORACLE_SID and ORACLE_HOME if i connect from "cmd" prompt but if i would like to connect from SQL*plus byspecifying "USERNAME,PASWORD and HOStSTRING" how can i connect,is there any way with SQL*PLUS or else i have to connect from "cmd" prompt only for multiple databases in windows XP
I also recommend its time to move to SQL Developer or Toad. The sqlplus you are talking about is the windows version (not the command line version) and is not included in 11g (deprecated as far as I know). The replacement is SQL Developer, it is free, check Oracle's site for a download.
http://www.oracle.com/tech
You can connect with SQL*PLUS with the username, password and hoststring.
The hoststring here indicates the tns entry in tnsnames.ora file.
Under your ORACLE_HOME\network\admin\
Example for tnsnames.ora file entry:
Ora10gR1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = <Windows XP machine name>)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID = <10gR1>)
)
)
Ora10gR2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = <Windows XP machine name>)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID = <10gR2>)
)
)
Now you can connect with the following connect strings in SQL*PLUS
1. Under Username give UserName/Password@Ora10gR1
2. Under Username give UserName/Password@Ora10gR2
If you would like to connect as sysdba, you sys/sysPassword@Ora10gR1 as sysdba or sys/sysPassword@Ora10gR2 as sysdba.
