Pro*COBOL Precompiler generates error PCB-S-0550 and 12154 when attempting to connect to the database:

Unable to log on to ORACLE with "'userid". ORACLE error number: 12154

Oracle error number 12154 equates to error message ORA-12154:

ORA-12154: TNS:could not resolve the connect identifier specified

Cause: A connection to a database or other service was requested using a connect identifier, and the connect identifier specified could not be resolved into a connect descriptor using one of the naming methods configured. For example, if the type of connect identifier used was a net service name then the net service name could not be found in a naming method repository, or the repository could not be located or reached.
