Title: RE: Win2000/8.1.7.3.0/SQL Hi Mike, I got 'DEFAULT'. After 'alter table ... noparallel', it was '1'. From Metalink 66484.1: (3) If any table in a query has a parallel degreee greater than one (including the DEFAULT degree), Oracle uses the cost-based optimizer for that query--even if OPTIMIZER_MODE = RULE, or if there is a RULE hint in the query itself So, since you said that a RULE hint makes it work, this may not be the problem.

RE: Win2000/8.1.7.3.0/SQL
Title: RE: Win2000/8.1.7.3.0/SQL I think you are on to something Jared. We had this happen at a production site last year. For some reason, the site began reporting performance problems after upgrading from 7.3.4 to 8.1.6. I finally tracked it down to the fact that a majority of our tables had 'degree' set to 'DEFAULT', which forces the use of the CBO. We fixed this by doing 'alter table noparallel' for all the tables which set degree to 1 and solved the problem.

RE: RE: Dba tools on NT
Title: RE: RE: Dba tools on NT
Stay on the good side Jared. Your code snippet looks great to me, and looking at it finally showed me a clear example of how that q{} thingy works. I write a lot of Oracle utility type stuff that has to run on both Windows and UNIX. Perl does the job every time.
Rachel, Jared should admit that he would probably need just a few more characters (about 6 alpha and 48 special!) to actually run the code, but the essence is there and with a glance you can tell that it does produce CSV output using DBI/DBD to access the database.

I have an user on both DG-UX and HP-UX which is not in the 'dba' group. Connection (internal or tcpip) works fine on both systems with following setup:
export ORACLE_HOME=/u01/app/oracle/product/8.1.7
export ORACLE_BASE=/u01/app/oracle
export ORACLE_SID=ORCL
export ORACLE_PATH=.:${ORACLE_HOME}/bin:/opt/bin:/bin:/GNU/bin/make:/usr/ccs/bin
export SQLPATH=$ORACLE_HOME/sqlplus/admin
export PATH=${PATH}:${ORACLE_HOME}/bin:/usr/contrib/bin/X11:${OBK_HOME}/bin
I initially got the 'oracle not available' error on HP-UX when I tested this just now on both systems, but then realized that the HP was running 8.1.7 and DG was on 8.1.6. I had forgotten to set oracle_home correctly to 8.1.7. :) Once I did that, all was fine.

ALL of my exports are done with direct=y option. I can demonstrate very easily that there will be 'redo' generated when doing the import by putting the importing database into archivelog mode and turning off the archiver process. If redo is not being produced (as you state), why do I see messages in the alert log telling me that the database is halted because all my redo logs are full and need archiving?
