I have an excel file which was developed by my predecessor and which uses external data connection to fetch data from Oracle.
I am trying to migrate this file to a new client PC and I am getting the following error while refreshing the data:
ora 12154 tns could not resolve the connect identifier specified
The connection is established via DSN and TNS reference. The system specifications are as:
OS: Windows 7 64 bit Oracle Client: Oracle 10.2.0 32 bit. DSN Created in the 32 bit odbcad32.exe
TNSNames.ora is as under:
ODS_BKUP = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.146.64.132)(PORT = 1521)) ) (CONNECT_DATA = (SID = ODSDB) ) )
I am able to do Test connection succesfully from the DSN. TNS ping also working for the server. But when I refresh the data in excel, I am getting the error.
Connection String Given in excel
DSN=MP_Prod;UID=ODS_MPMON;PWD=ODS_MPMON;DBQ=ODS_BKUP;DBA=W;APA=T;EXC=F;FEN=T;QTO=T;FRC=10;FDL=10;LOB=T;RST=T;BTD=F;BAM=IfAllSuccessful;NUM
What am I missing?
