A debug session drove to the solution. I started Oracle with oemapp debug dbastudio and received this exception: NVFactory: _readNVPair expected ) NVFactory: _readNVPair expected ) NVFactory: _readNVLiteral expected LITERAL java.lang.NullPointerException at oracle.net.nl.NVPair.setAtom(NVPair.java) at oracle.net.nl.NVFactory._readNVPair(NVFactory.java) at oracle.net.nl.NVFactory.createNVPair(NVFactory.java) at oracle.net.nl.NLParamParser.addNLPListElement(NLParamParser.java) at oracle.net.nl.NLParamParser.(NLParamParser.java) at oracle.sysman.vdb.VdbUtil.findInTNSFile(VdbUtil.java:756) at oracle.sysman.vdb.VdbUtil.findInTNSNAMES(VdbUtil.java:723) at oracle.sysman.vdb.VdbUtil.buildConnectDescriptor(VdbUtil.java:272) at oracle.sysman.vdb.VdbSession.buildConnectionInformation(VdbSession.java:4122 ) at oracle.sysman.vdb.VdbSession.establishConnection(VdbSession.java:1249) at oracle.sysman.vdb.VdbSession.(VdbSession.java:763) at oracle.sysman.vdb.VdbAutoCommitSession.(VdbAutoCommitSession.java:266) at oracle.sysman.vdb.VdbSessionFactory.getNewAutoCommitSession(VdbSessionFactor y.java:1206) This exception occurs while parsing the tnsnames.ora and listner.ora. So after correcting my entries there, everything works fine again.
