Redo Log Files • Purpose: - store changes made to the database as a result of transaction and internal Oracle activities. • Characteristics: 1. By default, an Oracle 10g database contains three redo log groups, REDO01.log, REDO02.log and REDO03.log 2. Every Oracle 10g database must have at least two redo log groups 3. The database will write log entries to a subsequent redo log group when the previous redo log group fills up 4. As a general rule , there should be one redo log group for approximately every four database users that create action queries 5. Oracle 10g keeps track of the Redo Log file by using a redo log sequence number, this number is recorded inside the file as they are used 6. The redo log sequence number is different than the operating system file name that is used to identify the physical file 7. If the database is in ARCHIVELOG mode full Redo Log files are copied to Archive Log files before they are reused, otherwise they are written over 8.

Writing Intensive Course Rubric 2=Acceptable 1=Unacceptable Writing assignments are incorporated as an integral, ongoing part of the course, and the writing assignments are effectively integrated, structured, and sequenced in a way that clearly articulates how it helps students improve their writing Writing assignments are not incorporated as an integral component of the course, writing assignments are not structured and sequenced in a way that can help students improve their writing in any clear way From the course syllabus and course assignments, it is clear that students have many opportunities to receive constructive criticism on drafts, and the opportunity to revise their work, particularly drafts of longer projects. From the course syllabus and course assignments, it is unclear whether students have many opportunities to receive constructive criticism on drafts, or the opportunity to revise their work, particularly drafts of longer projects. From the course syllabus and course assignments, it is clear that assignments and course planning devote ample time for students to reflect on their writing and their intellectual growth. From the course syllabus and course assignments, it is clear that assignments and course planning do not devote any time for students to reflect on their writing and their intellectual growth. As stated in the course syllabus, written assignments are a major component of the course grade. The course syllabus clearly and amply explains the writing-intensive nature of the course and contains a detailed schedule for writing assignments and revisions. Written assignments are not a component of the course grade. The course syllabus does not explain the writing-intensive nature of the course and does not contain a schedule for writing assignments and revisions. The Writing Intensive Course has at least one rubric created for grading writing assignments and the rubric is distributed to the students before the writing assignments are due. The Writing Intensive Course has no rubric, and thus no rubric is distributed to the students before the writing assignments are due.
