| ORA-12545 | : |
Connect failed be target host or object does not exist |
| Cause | : |
The address specified is not valid, or the program being connected to does not exist. |
| Action | : |
Ensure the ADDRESS parameters have been entered correctly; the most
likely incorrect parameter is the node name. Ensure that the executable for the
server exists (perhaps "oracle" is missing.) If the protocol is TCP/IP, edit the
TNSNAMES.ORA file to change the host name to a numeric IP address and tryagain. |
More Information |
1. Check your tnsname using "tnsping" command on client side:
tnsping "your oracle service"
2. Check database listener (server side) if the specific service or SID is on
lsnrctl status
