Database Control

Question

Internet Explorer is telling me it cannot connect to my Database Web Page. I imported two Oracle 9i databases from a Solaris server to a Oracle 10g new Windows 2003 server. I am building another Oracle database on this same server. I can access all three instances with plsql. Until recently, I could access the web pages of all three instances with Start->OraDB10g_home1->Database Control SID. I can still log onto two of the three SID web pages, but the third was giving me some security violation and now it just cannot access the page. I made all three web pages TRUSTED SITES. I am just getting my feet wet with Oracle 10g. Can someone please give me some insight into how I can restore access to my ServiceName:em#### web page? Thank you for your help in advance.

Answer 1

In a command prompt window, I entered
set ORACLE_SID=MYSIDNAME<enter> #MYSIDNAME=ACTUAL DB NAME
emctl status dbconsole
The output told me: Oracle Enterprise Manager is not running.
I tried another option of the same command. I again set the oracle_sid and then
emctl start dbconsole
The output told me: The requested service has already been started.
I tried Start->All Programs->Oracle OraDB10g_home1->Database Controle SIDname
Again Internet Explorer could not connect to the window to manage my database.
I tried stopping and then restarting the service OracleDBConsoleSIDname by right clicking on MyComputer, selecting Manage, selecting Services, and then right clicking on the service to select stop and then later to start.
The service took a long time to stop. Then it took forever to start. The status says Starting for a long while (between a minute or two).
I looked at some log files to see what was going on.
In the emoms.log, I saw such error messages as:
2008-08-12 19:40:23,316 [HttpRequestHandler-160937764] WARN jdbc.ConnectionCache _getConnection:306 - IO exception: the Network Adapter could not establish the connection.
ERROR eml.OMSHandshake get ParameterFromDB.563 - Io exception: The Network Adapter could not establish the connection
I found a more recently dated error message from the time I was trying to restart the DBConsole service for the database in the file Oracle DBConsoleSIDNamesrvc.log
The following line was repeated many, many times as if a process was being retried inside a loop:
08/20/08 09:57:15 Received exitCode 1 from emctl istatus
08/20/08 09:57:23 Received exitCode 1 from emctl istatus
08/20/08 09:58:15 Received exitCode 1 from emctl istatus
and then finally
08/20/08 09:58:23 Received exitCode 3 from emctl istatus
08/20/08 09:58:30 dbconsole started
DOES ANYONE HAVE ANY IDEAS WHAT I CAN DO TO MAKE THIS SERVICE START PROPERLY SO THAT IT HANDSHAKES WELL WITH MY DATABASE WINDOW?
