Hi Rajiv,

Use DBCO to configure connection with a Remote Database. Also take a look at the OSS Note : 339092.

Also take a look at this link.

Thanks Premal,

I have done configuration using DBCO but as long I know there need to enter configuration in TNSNAMES.ORA in SAP Direcorty like oracle.

How can I edit or create the file TNSNAMES.ORA in sap system?

Hi Rajiv,

Make sure of the following 3 steps.

1. There are 2 tnsnames.ora files in the netweaver-based systems. One is the traditional in the oracle's network\admin folder.

The other one, the one that SAP DBCO uses in sapmnt\<SID>\sys\profile\oracle.

Make sure you add the tnsname entries right there, as DBCO will read from there.

2. You can also try to go to the command prompt and do a tnsping on your connection name, if it is successfull, you are on track.

3. Finally, the DBCO entry Connection Information, should be same as your GLOBAL_NAME Connection name from your .ora file.

I have created a entry using DBCO named SAP_ORA with user /password etc.

and getting path in sap system for oracle that is DIR_ORAHOME /oracle/RTD/920_64 using AL11.

but for tnsnames.ora where to go?

[premal_mistry2]

Hi Rajiv,

Try this path \usr\sap\<SAP-SID>\SYS\Profile\oracle\.

Not getting such path but there one path like below.

/usr/sap/RTD/SYS/profile

but how can I use this and edit this for tnsnames.ora?

[premal_mistry2]

Hi Rajiv,

Traverse to this path /usr/sap/RTD/SYS/profile in your application server, there you will find a directory named ORACLE . Just go into that directory look for the tnsnames.ora file.

Premal

I am locatting the path /usr/sap/RTD/SYS/profile using Tcode : AL11

If you've access to the Server, you can find this path in your SAP Server.
