Well this is from the 8.1.7 Doco Concepts guide Section introduction to an instance, and I quote "This combination of the SGA and the Oracle processes is called an Oracle instance." It doesn't include the initora file, the concepts guide a bit further into it is this one "To start an instance, Oracle must read a parameter file--a text file containing a list of configuration parameters (initialization parameters) for that instance and database". So if I read that correctly what we generally all refer to a "database" ie instance all files etc consists of three components: instance, database, and parameter file.
"After starting an instance, Oracle associates the instance with the specified database" I refers to mounting the database so all things that are connected to an instance when you mount is the database. that would include all dbf file, redo, archive. That would make the alert log though part of the instance So now where did I go wrong Cheers -- ================================================= Peter McLarty E-mail: [EMAIL PROTECTED] Technical Consultant WWW: http://www.mincom.com APAC Technical Services Phone: +61 (0)7 3303 3461 Brisbane, Australia Mobile: +61 (0)402 094 238 Facsimile: +61 (0)7 3303 3048 ================================================= A great pleasure in life is doing what people say you cannot do. - Walter Bagehot (1826-1877 British Economist) ================================================= Mincom "The People, The Experience, The Vision" ================================================= This transmission is for the intended addressee only and is confidential information.

Here is the scenario. I have a co-worker that is preparing for the DBA OCP debacle. They have completed a significant portion of the training and are preparing to take the first set of exams. To see what they have learned, I asked them to define what comprises an Oracle Instance and what comprises an Oracle database. Here are the responses I got: An Oracle Instance The database instance contains storage areas that allow users to use the database, data dictionary, redo log buffers and various processes that help to maintain, tune and run the database An Oracle Database The Database files consist of the parameter file or init.ora file, the physical data files, the control file and the redo log files and archived log files if the database is run in archive log mode Now, we all know that an Oracle instance comprises the background processes, the memory processes, memory storage areas, the and INIT.ORA parameters whereas the database comprises the physical files, data dictionary, users, objects, etc. The problem I have is the education is being supplied by our favorite vendor, Oracle. Did I go on vacation too long or is Oracle professing incorrect information in the OCP. Can one of the people that has taken the exam the classes look this up in the manuals for me? This proves my theory of refusing to take this exam unless hogwhipped and tied down (Rachel, sit down please and thanks for volunteering). If bad information is being given, then what's the use of the exam? Thank You Stephen P.
