On the heels of Progress buying MindReef and IONA, Oracle has acquired ClearApp. ClearApp monitors SOA performance and tracks runtime environment changes to ease the burden of finding application and performance problems in complex SOA environments. ClearApp also supports WebSphere. In some SOA environments, "IBM shops" using WebSphere might now use three components from Oracle: Tangosol, ClearApp, and DB. Oracle is clearly positioning themselves to have a homegenous solution in order to siphon market share from IBM. Good move, Oracle. Your turn, IBM.
