V3.1.0.1 Student Exercises pref Exercise Description Each exercise in this course is divided into sections as described below. Select the section that best fits your method of performing exercises. You may use a combination of these sections as appropriate. Exercise Instructions This section tells you what to accomplish. There are no definitive details on how to perform the tasks. You are given the opportunity to work through the exercise given what you learned in the unit presentation, utilizing the Student Notebook, your past experience, and maybe a little intuition. Exercise Instructions With Hints This section is an exact duplicate of the Exercise Instructions section except that in addition, hints (which are not solutions!) are provided to help step you through the exercise. A combination of using the Exercise Instructions section along with the Exercise Instructions With Hints section can make for a rewarding combination. Exercise Instructions With Solutions This section is also an exact duplicate of the Exercise Instructions and contains solutions and additional tips for the students. If very inexperienced students take part in this course, they should work with this section. Students can use this part to compare their work with the solutions. When showing the SMIT method to accomplish a task, each line in bold represents a submenu or selector screen. You will need to press the Enter key after selecting each item as listed. When you reach the dialog screen, the field descriptions will be in regular text and the items you need to fill in will be in bold. Only the items that need to be changed will be shown, not the entire screen. Once you have reached the dialog screen portion of SMIT, press Enter ONLY after all indicated entries have been made. The SMIT steps will be shown for the ASCII version of SMIT. Under most circumstances these steps match the steps taken if using the graphics version of SMIT. The exceptions relate to the use of the function keys. When instructed to press the F3 key back to a particular menu, when in graphics SMIT, you will instead click the Cancel box at the bottom of the screen. When instructed to press the F9 key to shell out, in graphics mode, simply open another window. © Copyright IBM Corp. 1997, 2004 Exercise Description vii Course materials may not be reproduced in whole or in part without the prior written permission of IBM. Student Exercises Note: The new wsm interfaces are currently not shown. Optional Exercise Parts Some labs provide additional practice on a particular topic. Specific details and/or hints are provided to help step you through the Optional Exercises, if needed. Not all exercises include Optional Exercises. According to the group, the instructor can decide to do them or not. If there is time, the optional part should be executed by the students. viii AIX 5L Problem Determination © Copyright IBM Corp. 1997, 2004 Course materials may not be reproduced in whole or in part without the prior written permission of IBM.
