Set role does not appear to be working

Question

Below, I've listed two blocks of code. The first block executes just fine. The second block throws an exception on the last line. The error returned from the server is "ORA-04043: object PERSON_VIEW does not exist". The only difference between the two blocks of code is how they log in. The first block logs in as a user with more rights. The second block logs in as a user with very little rights, but obtains more rights using the "set role" statement. I used SQL Plus to log in manually as the second user, executed the "set role" statement, and had no problem describing PERSON_VIEW. What am I doing wrong in the second block of code?
Environment *pEnv = Environment::createEnvironment( Environment::OBJECT);
Connection *pCon = pEnv->createConnection( "MYAPP", "PASSWORD", "MYDB");
MetaData data = pCon->getMetaData( "PERSON_VIEW", MetaData::PTYPE_VIEW);
Environment *pEnv = Environment::createEnvironment( Environment::OBJECT);
Connection *pCon = pEnv->createConnection( "USER", "PASSWORD", "MYDB");
Statement *pStatement = pCon->createStatement( "set role MYAPP_ROLE identified by PASSWORD");
pStatement->executeUpdate();
MetaData data = pCon->getMetaData( "PERSON_VIEW", MetaData::PTYPE_VIEW);

Answer 1

In case anyone cares, the actual problem is that the OCCI throws an Ora-4043 when describing a SYNONYM in 10.1.0.3. This has been designated a bug and assigned to the development team. :o)
