... and send the DB engine to the cleaner .... closing the query => close the cursor and free some memory is probably a better solution indeed ...
however IMHO you should think twice to run 1000's queries in parallel, or even sequentially if it is not necessary, (you are each time paying a huge overhead ... network, query opt, ....) and you should probably consider to change the way you populate your xml from the db ... and except for the last entence it is not xml related .... so I apologise :) jc >Hello Celinio, > >I have some ORACLE background, and here is what I would say: > > - every SQL statement you run against an ORACLE server > opens a database cursor implicitly > - there is an "OPEN_CURSORS" parameter in the "init.ora" > file that the server uses for its own initialsation; > the default value is 50 > - the "OPEN_CURSORS" parameter defines the maximum of open > cursors a given user can have in parallel > - to avoid the given ORACLE error message, you should > ask your ORACLE admin to change the "OPEN_CURSORS" > value in the "init.ora" file (the file name may be > different in your environment!) to a much higher > value, let us say 1000 or so; or ask the admin > for his/her experiences > >I hope this will help you with your ORACLE problem. > >Regards, > Hans-Dieter Cordes > >-----Original Message----- >From: Celinio Fernandes [mailto:[EMAIL PROTECTED] >Sent: Dienstag, 2.
