Hi,

I am using Oracle 10.2.0.1.0. My intention is to create a new database instance.
Here are the steps I have taken,

1. Using DBCA, I created a new database instance, oracle sid = MYORCL0318
2. I created the tablespaces for this instance.
(I obviously have not imported any data into this database yet.)

then, I went to Enterprise Manager,

Login = sys
password = xxxxxxx
role = SYSDBA

After I login, I would get an Error like this

java.lang.Exception: Exception in sending Request :: null

Does anyone have any idea why this is happening and how to fix this? (please let me know if you need additional information.)

thanks in advance for your help,
ST

> I created the tablespaces for this instance.

How did you do that?

EM has a logfile.
What clues exist in it?

Sorry for the late reply, I was in meetings all morning.

Ok, to create tablespace, I used the following command,

CREATE TABLESPACE APPLICATION_DATA
DATAFILE 'C:\databaseFiles\MYORCL0318\APPLICATION_DATA01.dbf' SIZE 500M AUTOEXTEND
ON
EXTENT MANAGEMENT LOCAL AUTOALLOCATE
LOGGING
ONLINE
PERMANENT
SEGMENT SPACE MANAGEMENT AUTO
/

and I created about 38 of them. I checked the file system, they seem to be created successfully.

When I log into enterprise manager, I would see the "java.lang.Exception: Exception in sending Request :: null" error at the top of the screen,
I went to check the emoms.log, I'd get these errors in the log file,

again, my objective is to create a completely new instance from scratch, then, I can import a database dump (from our TEST server) into this instance.

thanks,
ST
