Explain plan suddenly changing to FTS.

Hi All,

We have frequently facing one issue in one of our database, where same SQLs are getting parsed with different explain plans. Mainly when it start FTS, we are bouncing the DB and after that SQLs start behaving normals. We have changed cursor_sharing parameter from SIMILAR to EXACT but still no luck.

Oracle Version : 11.2.0.3

Could you please help me to understand this DB behavior.

Many Thanks,

Howdy, Stranger!
