Something funny:
There is a procedure that uses 'select for update'. When this procedure is executed in the production env. (v8.1.6.2.0), it works fine, but if executed in the development env. (v.8.1.6.3.0), it throws this error. The code is the same in both cases and both dbs are on the same platform (HP-UX 11). Any bright ideas?? Thanx.
