REM --- Drop GE-customized tnsnames.ora / sqlnet.ora / ldap.ora into ORACLE_HOME.
REM     The zip ships these in client\ora\ but Oracle's setup.exe does not consume
REM     them - that copy is the GE Wise wrapper's job, which we bypass. Without
REM     these, every Oracle-dependent app (eDNC/UDC/NTLARS/CMM tooling) fails with
REM     ORA-12154 "TNS could not resolve the connect identifier specified".
REM
REM     Per-file override: if %~dp0<name>.ora exists (deployed alongside this
REM     wrapper on the PXE server / SFLD share), use it instead of the bundled
REM     copy. Lets us push an updated tnsnames.ora without repackaging the zip.
REM
REM     Only run when OUI succeeded (RC 0 or 3). On failure ORACLE_HOME may not
REM     be fully populated and the copy targets may not exist.
