Database connectivity requiring oracle wallet, tnsnames.ora, and sqlnet.ora
We have a new datasource that I need to write a report against. In order to access the db, I have to install an Oracle wallet on my pc that contains a certificate. I then have an entry in the sqlnet.ora file that references this wallet, and I have an entry in my tnsnames file. I wrote a report successfully on my pc. We then have our Business Objects installation on a Sun Solaris machine with Unix. We installed the wallet, added the sqlnet.ora entry, and the tnsnames.ora entry. I am able to connect to the db from the unix command prompt by typing sqlplus username@dbname successfully. However, when I place my Crystal Report in Bus. Obj. I cannot get it to work. I go to the CMC, select the report, choose Process, Database. I am entering Use custom database logon info and choosing Oracle as my database driver. I then enter the tnsnames entry into the server and enter my username and password and check the use use same database logon as when report is run. I get the error The database logon information for this report is either incomplete or incorrect. I'm guessing the report is not using the certificate in the wallet when it is trying to log on, but I'm not sure. Does anyone have any suggestions or experience with this? Thanks in advance for any help.
Hi Angie,
you should install the 32bit Oracle driver on your Solaris machine and adjust the LD_LIBRARY_PATH environment variable (in the profile of the BOBJ installation user) to point to the path of the 32bit libraries of your Oracle driver.
BOBJ is not a native 64bit software and can therefore work only with the 32bit versions of the database drivers.

Stratos

Connect with ldap.ora and sqlnet.ora
Hi
I am trying to connect Raptor to 9i oracle server. Our server connects using ldap.ora and sqlnet.ora files. I looked at some threads about this issue but do not understand how to connect. Is there a step by step instruction for connecting this way?
Thanks
DHHi VRamirez,
That's a pretty cool workaround. I'm sorry to hear it didn't work perfectly.
Here is the "low tech" workaround anyone can use -
From the %ORACLE_HOME% where your sqlnet.ora is, run %ORACLE_HOME%\bin\tnsping eg.

C:\>
Now copy the (DESCRIPTION=...) and paste it into the advanced TNS info tab in the Connections dialog. This works for me for everything but RAC TNS aliases which have load balancing and failover configured -- the advanced TNS info tab chokes on those. For such connections, I was able to use the JDBC string.

Listener.ora and tnsnames.ora and sqlnet.ora
Hello newbie here, trying to look into simple RAC setup with 2 nodes (A.this.com, B.this.com), one service (PROD.this.com), one listener and one instance on each node (listener PRODlist1 using instance PRODinstance1 on node A, listener PRODlist2 using instance PRODinstance2 on node B), one database (ORCL).
db global db name = orcl.this.com
I would like loadbalancing=on, with TAF basic (no preconnect, retries 10, delay 5.)
With dynamic service registration.
What should the tnsnames.ora and listener.ora and sqlnet.ora look like?
Have read all sorts of literature, getting confused...I post my sample configuration here:
DBA1.WORLD =
(DESCRIPTION =
(ADDRESS_LIST =
(FAILOVER=ON)
(LOAD_BALANCE=ON)
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.1)(PORT = 1521))
(CONNECT_DATA =
(BACKUP=DBA2)
(SERVICE_NAME = DBA.WORLD)
DBA2.WORLD =

Hi there!
My problems is regarding connection to Ora Frms/reports which for so many days I am trying but to no avail.
Some are suggesting to copy TNSNAME.ORA AND SQLNET.ORA for in order to work better connection on FORMS/REPORT.
Kindly advice on how to do it.
thnaks
nullIf you use 8i, form and report use TNS
config from sqlplus. If you can get in sqlplus does not mean you can log in
form ad report. You need to Config the TNS in an option called something like
'Network Config Assistant'or similar. You should find it from the list.
Another is to edit the TNSname.ora in the admin directory under you form and report initial path with the command from the previous mail -
Oracle 10g I don't have the files listener.ora, tnsnames.ora and sql.ora
Hi folks,
I uninstalled my Oracle 10g and when I re installed I got success, but when I went to the folder \network\admin didn't have the files listener.ora, tnsnames.ora and sql.ora. I have been trying during more than one month start my listener only because I need access the Oracle database from my Java application and I got the message:
java.sql.SQLException: Io exception: The Network Adapter could not establish the connection
As additional information, I got no problem to access the SQL*Plus.

Thanks in advance.Thanks ALL, I GOT IT, but I used other solution.
Since I installed and uninstalled the Oracle several times, it keeps also many different Services for the listener. I don't know why, it didn't create a Service for my actual instalation with its path. In other words, all the services remained in the services.msc panel, had the path that was already removed from the Windows folder.
Then what I did, was that I picked one service, took its name (OracleOraDb10g_home1TNSListener), went to regedit to [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\OracleOraDb10g_home1TNSListener] and simply changed the image path that was setted for the one that was removed (C:\oracle\product\10.1.0\Db_2\BIN\TNSLSNR ) for mine that is installed right now
(C:\oracle\product\10.1.0\Db_1\BIN\TNSLSNR). Nothing more and finally works.
I have tried something in the services.msc panel before, as you can see in this forum at the thread "I can't start listener in the Control Painel/Admin Tools/ Services", but I never got
success.
Appreciate your time!! -
Connection between oracle forms10g on XP and oracle db 11g on WINDOWS 7
Hello,
I am trying to connect forms 10g R2 to oracle 11g.
My forms is on windows XP inside VMware while my db is on windows 7 64 bit host.
i have tried all ways known to me and the ones i saw on the internet but none works.
I will be glad if you can refer me to a link that talks on this type of connection in details or any solution you can provide.
Thanks in anticipation
AbdurRahmanThank you for your response,
1) I copied the tnsnames.ora,sqlnet.ora and listener.ora files from the database 11g on the windows 7 host to the DevSuiteHome_1\NETWORK\ADMIN path for the developer
suite 10g on XP Vmware.
2) I also entered the host address in the C:\WINDOWS\system32\drivers\etc\host file i.e 192.168.202.54 AAJANI-pc.

What should have in equal tnsnames,ora and listener.ora?
Hi forum members again I'm very new in oracle, and I'm trying to create a sucessfull net service name, using oracle net configuration assitant, but when I try to test it I got this error, .***"""ORA-12514: TNS:listener does not currently know of service requested in connect descriptor."""*** And I have read that tnsnames.ora and listener.ora should have some parameters in common, but exactly I don't know, Do you know what parameters should be? or The ORA-12514 problem , doesn't have relation with the tnsnames.ora and listener files?, If doesn't wich is the reason of this message?

Thanks in advanceOK, here we go ... extra long as I intend to bookmark this and make reference, as this is a very common question ... skip to the bottom if you want my guess to the solution.
Oracle Net Services (formerly SQL*Net, Net8, Oracle Networking) has two parts - the client and the server side. I'll discuss the server first, then the client.
1) Server, and specifically Listener:
The Oracle Listener is a monitor that listens for Oracle service requests on one or more ports. Usually this is on TCP/IP port 1521. When it gets an Oracle request from any network client, it checks whether it's in the list of Oracle Services for which it is monitoring. If found, it will contact that service, request a connection for the client, tell the service and client where and how to connect, and get itself out of the loop.
Notes:
a) It can listen on behalf of any number of services;
b) A service can be a database instance, an EPG service (the DBMS_EPG is the replacement for Apache in the database in 10gR2), an external job, etc;
c) One listener can listen on behalf of multiple database instances;
d) The services can be listed in the LISTENER.ORA or they can self-register;
e) If databases self-register, they use the initialization parameter LOCAL_LISTENER
f) If self-registering, the listener should be up before the database
g) Shutting down the listener will stop future connections, but has no impact on existing ones.
One frequent point of confusion - a connection request on the local machine may loop out to the network and contact the listener, or it may bypass the listener entirely and use a bequeath adapter. The 'beq' connection is the 'normal' connection by "sqlplus / as sysdba" or "sqlplus system/manager" on the local machine (note that no @instance was used ... in *nix, that is derived from the $ORACLE_SID environment variable)
In your listener.ora, you specify global_dbname=oracle.gentoo and sid_name=oracle. I assume therefore you can find an initoracle.ora or spfileoracle.ora somewhere on your system.
2) Client:
A client that wants to connect to an Oracle service uses the client side of the Oracle Net Services. The definition of client includes: any Oracle client utiltiy (SQLPlus, SQLLoad, Forms, Reports, etc.); an Oracle database instance that wants to make a external procedure call or a dblink; third party tools such as ODBC and JDBC.
In SQL*Net version 1 the connection was made by specifying the target in the connect string ("user/password@host:listener_port:sid") and that is also used these days by many JDBC drivers, especially the Oracle Thin JDBC driver. Oracle's Easy connection mechanism uses a similar variant.
Since SQL*Net Version 2, Oracle has supported the concept of alias translation. Basically it's very similar in concept to DNS - give it the name of the service and tell it where to find the translation table. The translation tables include TNSNAMES.ORA, ONAMES servers (deprecated in 10g), LDAP usng Oracle's OiD. The choice of translation table, and alternate order if the lookup fails in one, is stored in the SQLNET.ORA (if one exists).
Assuming TNSNAMES.ORA, the chain of events is:
- get the alias to look up (in your case NORACLE);
- if the SQLNET.ORA has a DEFAULT_DOMAIN setting, (often =WORLD) append a dot and that value to the alias;
- go to the TNANSMES.ORA file pointed by the TNS_ADMIN variable (environment or registry), or (if not set) the one in the $ORACLE_HOME/network/admin directory;
- look up the first occurance of the alias;
- if found, use the protocol specified to request a connection to the host, usin DNS to unravel the host to an IP address if necessary (in your case TCP/IP, to TUX) ;
- if host connection if made, connect to the listener that is configured for that port (in your case 1521);
- if listener is there, ask it for connection to the service (in your case, you are asking for instance 'noracle');
i if the listener knowwss about the service, it will hand off the request.
Your problem appears to be asking for instance 'noracle' in the tnsnames but listeneing for 'oracle' at the listener. Of course, I can not see any auto-registered instances which you would get from "lsnrctl status" on the server. -
I am studying oracle and came accross
tnsnames.ora and listener.ora file.
Can any one tell me in simplified terms about these 2 files. what are they and what exactly they do?When you are accessing Oracle over network you need a listerner service (usually on server box) and SQLNet or Net8 client on client machine. Listener.ora specifies the parameters for listener process and tnsnames.ora contains the SQLNet or Net8 connection informations about database server(s)

Best Practices: tnsnames.ora and listener.ora
I would like to know if it is better to use the public ip / public hostname or the virtual ip / virtual hostname in the tnsnames.ora and listener.ora files on the servers and clients. I have seen examples where the vip is used for all areas, and I have seen examples where the public has been used in all areas. And of course even some examples where both are used. It makes more sense to me to use the vip, as that is what is failed over But what is the public ip used for if all connections are made to the vip?

172.16.72.52 rac3.somcompany.com rac3vip # RAC3
172.16.72.53 rac3.somcompany.com rac4vip # RAC4
So if I was to create a tnsnames files on the servers, would I use the vip information as the host or the public information?
Would I use the same tnsnames files for the clients?
Would I use the vip or public address in the listener files?

Tnsnames.ora and listener.ora dissappearing
We are ruinning oracle 9.2.0.6.0 on Solaris 9 on a Sun-Fire-440.
We are having an issue where the above mentioned files (tnsnames.ora and listener.ora) keep dissappearing on this box.
We cannot seem to find anything in the unix logfiles or oracle log files, has anybody got any ideas on what could be causing this?
Mark Stewart.If the files are being deleted then the timestamp on the directory which contains them will be updated ( given by ls -l ) . this would enable one to find out the time when they were deleted ( as long as nothing else in the same directory is being changed ) . It would be interesting to see if the deletes always happen at the same time , which would imply some automatic process , perhaps running under cron.

This makes no sense. You don't configure a listener nor a tnsnames.ora "in a database". I hope this is just a language issue and not reflective of a fundamental misunderstanding of how tns works.

I wonder if we still have initSID.ora and pfile.ora in oracle database 9i2? if we have, where are they? thanks
If you are using the parameter file, you should find it in $ORACLE_HOME/dbs or $ORACLE_HOME/database folder depending on your operating system.

Connect to Oracle DB using DBCP and tnsnames.ora
I have a Spring-based web app that is running on Tomcat and uses DBCP to connect to Oracle.
The problem:
Need to pull database connection information from tnsnames.ora file. There is Oracle Client installed on a server, so tnsnames file is available.
According to JDBC documentation, the following url should do the trick: jdbc:datadirect:oracle:TNSNamesFile=c:\\oracle\\product\\10.2.0\\NETWORK\\ADMIN\\tnsnames.ora;TNSServerName=FITZGERALD.SALES
This leads to the following declaration in dataAccessContext-local.xml file:
+<bean id="dataSource" class="org.apache.tomcat.dbcp.dbcp.BasicDataSource" destroy-method="close">+
+<property name="driverClassName" value="oracle.jdbc.OracleDriver"/>+
+<property name="url" value="jdbc:datadirect:oracle:TNSNamesFile=C:\\oracle\\product\\10.2.0\\db_1\\network\\admin\\tnsnames.ora;TNSServerName=TESTDB"/>+
+<property name="username" value="${jdbc.username}"/>+
+<property name="password" value="${jdbc.password}"/>+
+</bean>+
This doesn’t work for me saying that database url is invalid.
Can anyone provide instructions on how to set up DBCP with tnsnames.ora?
Any help greatly appreciated.You are right, the I got that url may not be correct. I got it from datadirect documentation.
I couldn�t find any good information or examples on this, but I think using TNS keyword-value pairs and tnsnames.ora is supported by type4 Oracle 10g JDBC.
Some info I found in section �Connecting to the Database through the Applet� in JDBC Reference http://download.oracle.com/docs/cd/B19306_01/java.102/b14355/jdbcthin.htm#CACCHECD
I guess there is something off in that documentation though. I couldn't get it working.
