Error: ORA-12505, error when i want to change database in webaccess.

Hello
I want to change the database for webaccess. I use a database in MS Sql Server now. for that I choose "Database Configuration Setup" from the Start menu,
Programs, Oracle - Primavera P6> Primavera P6 Web Access Utilities . I open this tool and in the 1st step I select Oracle in the 2nd step I entered the below informationusername and passsword: admuser
database name: pmdb (I create this database before and I tested that successfully in P6)
Database Host Address: *127.0.0.1*
Database Host Address: 1521 (I'm sure the port is 1521)
I didn't select SSL and Public Group ID set to 1
after i click on next one error returned that "ORA-12505, TNS:listener does not currently know of SID given in ..."
I added XE as SID before database name and correct database name to XE:PMDB. but I below error returned:
Error:Unable to resolve privileged username and password
Invalid connection string
format, a valid form at is: "host :port:sid"
Please verify the information you entered.

wow, I found the solution.
you must set database name as XE
correct information are as below:
username and passsword: admuser
database name: XE
Database Host Address: *127.0.0.1*
Database Host Address: *1521*
then click next.

ORA-12505, error when i tried to open the "Workflow Administrator" tool

i have installed Oracle content server 10g r3, but when i tried to open the "Workflow Administrator" tool i got the following error "ORA-12505, TNS: listener does not currently know of SID given in connect descriptor", so how can i solve this issue?
//hint i am using Oracle database 10g

Is the rest of your UCM install running OK?
This implies that the JDBC connection is failing.
Are you running Workflow Administrator from the Admin Applets in the browser OR as a standalone application from command line (*nix) or Start menu (windows)
I think that the application would normally look in config.cfg and use the JDBC connection string given in there - this would include the SID. Can you tnsping the SID?

For #5, not Windows, ConfigMgr 2012 R2. Anything before ConfigMgr 2012 R2 is not supported for the 8.1 ADK.
For the permissions, what accounts are you setting this for. In general, if the share is on the same server, Everyone Full or Read on the Share and System Full or Read on the NTFS should work.
For the error message, it looks like you are trying to import an OS Image and not an OS Install Package. OS images use a WIM file and OS Install Packages use the entire set of source files from the media. For OS images, you must thus explicitly point it
to a specific WIM file.

Obviously there is no handler for XE service.
Maybe you changed hostname(this should be "Owner-PC") ?
Try to manually start/stop db and see if there are some errors:
sqlplus / as sysdba
startup
shutdown immediate
If after that you still can't find cause, try to ask on oracle db forum.

Hi ,
When I am running the jdeveoper for my adf application , I am getting the follwoing error:

=================================================
I am using scott as the dabase name i.e. SID is scott and jdev version is 11.1.1.2, I am able to connect to scott database using sqlplus. e.g. hr/hr@scott is working fine in sqlplus.
Any suggestions
Thanks in advance

Thanks for the response Frank,
I got this issue resolved, I did find out that there were 2 db connections were there , One Connection I name was Scott and other as FOD. Scott had correct SID, and FOD had incorrect SID as XE. So I deleted the FOD Connection. and renamed the Scott Connection to FOD( SID is still Scott).

Indeed, as Sybrand said, I wasn't paying attention. My bad. Also, I must admit I haven't googled the error too much before posting here. But, hopefully, this is an open forum, and If anyone wants to answer to my problem, it will be great.

Listener refused the connection with the following error: ORA-12505

Hello,
Listener refused the connection with the following error: ORA-12505, TNS:listener does not currently know of SID given in connect descriptor The Connection descriptor used by the client was: 127.0.0.1:1521:XE Windows XP + Oracle 10.1.0.20
I checked my *.ora files and found the host 127.0.0.1 but I noted by running netstat command on dos prompt that most of my ports are captured by www.360.cn including 1521
when am trying to shutdown then the following message appears:

ORA-27101: shared memory realm does not existsThanks & best regards

Hi,
[oracle@myoramachine ~]$ oerr ora 12505
12505, 00000, "TNS:listener does not currently know of SID given in connect descriptor"
// *Cause: The listener received a request to establish a connection to a
// database or other service. The connect descriptor received by the listener
// specified a SID for an instance (usually a database instance) that either
// has not yet dynamically registered with the listener or has not been
// statically configured for the listener. This may be a temporary condition
// such as after the listener has started, but before the database instance
// has registered with the listener.
// *Action:
// - Wait a moment and try to connect a second time.
// - Check which instances are currently known by the listener by executing:
//    lsnrctl services <listener name>
// - Check that the SID parameter in the connect descriptor specifies
//    an instance known by the listener.
// - Check for an event in the listener.log file.
[oracle@myoramachine ~]$1. Check lsnrctl services <listener name>
2. Check tnsping output:
tnsping MYORACLE
3. Check connectivity to the machine where your Oracle Server resides to port ( I assume 1521):
telnet <your_machine> 1521
4. In case you're not able to connect to the Oracle Server - I'd investigate it in a few directions:
     - network infrastructure problem
     - some disturbing process(es) / virus(es) on Oracle Server itself
     - firewall issue
Good luck!

Do you have antiVirus installed on the sharepoint servers?
These folders may have to be excluded from antivirus scanning when you use file-level antivirus software in SharePoint. If these folders are not excluded, you may see unexpected behavior. For example, you may receive "access denied" error messages when files
are uploaded.
Please follow this KB and exclude the folders from Scanning.

ORA-12505 error with oracle 11.2.0.2 RAC Grid

Hi,
We have just installed Oracle 11.2.0.2 with oracle clusterware. Every thing went well during the installation, How ever after install we can not connect to the RAC instance from clients, through jdbc OR oracle sql developer.
We get following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor.
After the installation we created service (myrac) through OEM Cluster Managed Database Services tab. and We are using service name as following:
jdbc:oracle:thin:@orap-cluster.mydomain.com:1521:myrac
Here below is Service TNS string:
myrac = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = orap-cluster.mydomain.com)(PORT = 1521))(LOAD_BALANCE = YES)(CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = myrac)))
Any help..??
Cheers

HI,
to clarify:
if you try with
<SERVER>:<PORT>:<SID> you are accessing the server with a database SID, whereas
<SERVER>:<PORT>/<SERVICE> will access a service.
The SCAN Listener only know of services, and not of database SIDs.
This is the reason you should always create separate services for your RAC databases, since only they are registered. If you connect via. a service the listener will forward you to (one of) the corresponding instances servicing the service.
Database SIDs are only known to the local listener on the node (not to the SCAN listener). And SIDs actually should not be used anymore.
However if you still need to access the SID you can use the virtual hostname of the server resp. the VIP address of the server in the connection and this will work:
<VIP>:<PORT>:<SID>
Note the SID of a RAC database is either myrac1 or myrac_1 (depending on administrator or policy managed database).
I still would recommend using services and not SIDs.
Furthermore the SCAN can only be resolved correctly by 11.2 clients.
Any pre 11.2 client should use an address_list containing the SCAN VIPs:
PRE112 =
(DESCRIPTION =
(LOAD_BALANCE=ON)
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.41)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.42)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.43)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = pre112)
If a application server does not understand / then try using the TNSNAMES entry directly:
jdbc:oracle:thin:@(DESCRIPTION = (LOAD_BALANCE=ON)(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.41)(PORT = 1521))(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.42)(PORT = 1521))(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.43)(PORT = 1521))(CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = pre112)))
Hope that helps

my sqlnet.ora is:
============
# sqlnet.ora Network Configuration File: C:\oracle\product\10.2.0\db_1\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.
# This file is actually generated by netca. But if customers choose to

12514, 00000, "TNS:listener does not currently know of service requested in connect descriptor"
// *Cause: The listener received a request to establish a connection to a
// database or other service. The connect descriptor received by the listener
// specified a service name for a service (usually a database service)
// that either has not yet dynamically registered with the listener or has
// not been statically configured for the listener. This may be a temporary
// condition such as after the listener has started, but before the database
// instance has registered with the listener.
// *Action:
// - Wait a moment and try to connect a second time.
// - Check which services are currently known by the listener by executing:
//    lsnrctl services <listener name>
// - Check that the SERVICE_NAME parameter in the connect descriptor of the
//    net service name used specifies a service known by the listener.
// - If an easy connect naming connect identifier was used, check that
//    the service name specified is a service known by the listener.
// - Check for an event in the listener.log file.

ORA-12505 error help needed

I have 10g on my laptop and tyring to connect to my local db on Laptop via TOAD and gives me error ORA-12505.
here is my TNSNAMES.ORA file:
# tnsnames.ora Network Configuration File: C:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.
EZAUDIT.2020LLC.COM =

(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 2020-5056)(PORT = 1521))
(CONNECT_DATA =
(SID = EZAUDIT)
here is my LISTENER.ORA file:
# listener.ora Network Configuration File: C:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =

LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 2020-5056)(PORT = 1521))
"2020-5056" is my hostname of laptop.
"EZAUDIT" is my SID name, which is the local DB name.
Don't know what's going on. It was working fine for last 2 months, all of a sudden last 3-4 days i am having this issue. My Listener name is "LISTENER"
If I change the SID = EZAUDIT to SERVICEf_NAME = EZAUDIT in my TNSNAMES.ORA file then the error I get is ORA-12514. Don't know what the issue. Please let me know ASAP, have to finish the project by next week.
APPRCIATE your hlp.
THANKS,
Kas
