A quick google tells me...
Under an RR isolation level all page locks are held until they are released by a COMMIT (or ROLLBACK), whereas with CS read-only page locks are released as soon as another page is accessed. Repeatable read is the default isolation level if none is specified at BIND time. |

| The answer could have been found by looking at the Sticky entitled: DB2 - Interview Questions with Answers. Also, the intent of this forum is for the poster to attempt to answer their own question and then invite responses. |
