The examples you have given are SYS-recursive, The call to cdef$ is Oracle looking for some information about constraints (one possibility is that you keep breaking a PK or UK constraint and Oracle has to keep looking up the name of the constraint because it doesn't cache constraint names).
The call to seq$ usually appears because you are using a sequence with a very small, or no, CACHE set - so as you get the next value from the sequence, oracle has to bump the sequence high-water value and write it to disc. In general, the recursive depth simply tells you how far down the stack of calls your cursor is. For example (which may be wrong in detail, but right in gist) if you execute an anonymous pl/sql which runs an SQL statement that uses a sequence.nextval that happens to bump the sequence high-water, you would (probably see): anonymous pl/sql dep = 0 SQL statement dep = 1 update seq$ statement dep = 3 Regards Jonathan Lewis http://www.jlcomp.demon.co.uk Now available One-day tutorials: Cost Based Optimisation Trouble-shooting and Tuning Indexing Strategies (see http://www.jlcomp.demon.co.uk/tutorial.html ) ____UK_______March 19th ____UK_______April 8th ____UK_______April 22nd ____USA_(FL)_May 2nd Next dates for the 3-day seminar: (see http://www.jlcomp.demon.co.uk/seminar.html ) ____UK_(Manchester)_May ____USA_(CA, TX)_August The Co-operative Oracle Users' FAQ http://www.jlcomp.demon.co.uk/faq/ind_faq.html ----- Original Message ----- To: "Multiple recipients of list ORACLE-L" <[EMAIL PROTECTED]> Sent: 12 March 2003 16:15 > Thanks Jonathan, > what is meaning of recursive depth ?
