hello everyone

I am an oracle newbie running into a problem with starting my oracle databases. I am running Oracle 10 on a Windows 2k3 server. When the machine first boots up, if I try to connect to the database (either locally or on a remote machine) via sqlplus, I get the error message ORA-12545: Connect failed because target host or object does not exist, and am then prompted to enter my user name. However, if I merely go to the Database Configuration Assistant -> Configure database options, then select a database, once the first screen of options are displayed within the wizard, I am able to sqlplus in as expected.

The windows service for the TNS listener and the database service itself are both started before I first try to connect. Also, if I have multiple databases on this server, and I connect via the Database Configuration Assistant to one of them, that database is functional, but the other databases are not. It almost seems like the assistant is starting the databases

Does anyone have any recommendation as to what I can look into? Or what commands might be executed at this point for the database configuration assistant to enable connectivity?

As an additional piece of information, I am running the Windows 2k3 server on a VMWare image, using a bridged connection

thanks

> via sqlplus
Which flavor of sqlplus; windows interface which requires SQL*Net or command line which does not?

12545, 00000, "Connect failed because 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 try again.


Do you have simply a race condition?
Are you attempting to login before all the necessary s/w has been properly started?

After reboot, if you just wait 3 - 5 minutes is everything OK?

I see similar behavior both via the command line utility and the windos utility (although I get a different message when running sqlplusw.exe I get 'ORA-12170 - connection timeout'

I have tried rebooting the machine and waiting 10 minutes before attempting to connect, and get the same behavior. I also can, if accessed through the DCA, connect to the dB quite quickly.

In terms of what else can be started, the oracle database services OracleService<SID>, along with the listener, are set to automatic and started. Is there anything else I can look for?

What clues exist with alertSID.log & listener.log files?
Try to create an overall timeline between what happens when at the OS level & with the various Oracle components.

What changes & when that make everything work OK?

I think these logs (and your most gracious assistance) are leading me down the correct path

* I stopped all services, and deleted the two logs (alert-SID.log and listener.log)

* I restarted the machine and verify that the services for the SID and the listener are running
-alert-SID.log is not created, listener.log is created with nothing looking interesting

* I attempt to connect via SQLplus
- I get the error message from above, and the following is inserted into listener.log. alert-SID.log is not yet created
TIMESTAMP * CONNECT DATA [* PROTOCOL INFO] * EVENT [* SID] * RETURN CODE
25-JUN-2009 15:33:37 * (CONNECT_DATA=(SERVICE_NAME=dpn22)(CID=(PROGRAM=C:\oracle\product\10.2.0\db_1\bin\sqlplus.exe)(HOST=FGMETZ-OR10)(USER=Administrator))) * (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.192.1)(PORT=1028)) * establish * dpn22 * 12514

25-JUN-2009 15:33:37 * (CONNECT_DATA=(SERVICE_NAME=dpn22)(CID=(PROGRAM=C:\oracle\product\10.2.0\db_1\bin\sqlplus.exe)(HOST=FGMETZ-OR10)(USER=Administrator))) * (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.109)(PORT=1029)) * establish * dpn22 * 12514
TNS-12514: TNS:listener does not currently know of service requested in connect descriptor


* I launch the DCA wizard
- no entries to listener.log, alert-SID.log is not yet created

* I select the SID of interest to configure database options, and wait (a lengthy time, a minute or so) while information is retrieved, until the first page of options are available
- the following updates are made to listener.log
25-JUN-2009 15:39:53 * service_register * dpn22 * 0
25-JUN-2009 15:39:59 * service_update * dpn22 * 0

25-JUN-2009 15:40:38 * service_update * dpn22 * 0


- alert-SID.log is created. The following entries are added

At this point, my database is functional.

I have noticed that the ALTER DATABASE MOUNT and ALTER DATABASE OPEN commands are being applied here. I would think that would happen when the service starts up, no? Might this be improperly configured? I am an extreme novice when it comes to any oracle administration, so I may have done something foolish in the installation. However, the database creation scripts for this database are known to work properly, so it is something local here

Any ideas what might be going on?

Oh, and thank you very much for taking time out to help

I plead ignorance.
I have steadfastly avoided running Oracle on Windoze.
I don't really know the details how to get Oracle DB going after boot on Windoze.
One possibility is that you search the whole disk for a file by the name of "oratab".
If one exists, post the contents back here.

Hopefully, somebody who knows Windows can solve this riddle for you
