5.3.1 Exclude Libraries
Figure 24. - Exclude Libraries
This is the first screen of the Job Creation Tool. You can enter the libraries to be excluded from the Jobs. The excluded Libraries are not shown as selected on the Libraries selection screen.
F2: Saves the libraries to be excluded. F3: Exits from Exclude Libraries screen. F6: Displays the “select libraries” screen.
Notes:
2.
Wild card characters e.g. A*, B* etc. are not supported while specifying the library names.5.3.2 Select Libraries
Figure 25. - Select Libraries
The above grid displays the Jobs as column headers and the list of all libraries as row headers. Symbol ‘_‘indicates the particular library is not included in the respective Job. Symbol ‘X’ indicates the particular library is included in the respective Job. For example, in the above screen ‘#COBLIB’ library is included in Job ‘J1’.
1. Job Limit: Indicates approximate Jobs to be created by the Job Creation Tool. This parameter can be changed by the user, as required. By default the value will be ‘number of CPUs (including LPAR CPUs) X 4’. In case the number of CPUs is not retrievable, it is defaulted to 1 by the Job creation.
2. Object Size/Job: This is the optimal object size per Job as calculated by the Job Creation Tool. There can be instances where the size of the Job can be greater or less than calculated value of object size/Job.
3. Object Count/Job: This is the optimal object count as calculated by the Job Creation Tool. This is shown in multiples of 1000. There could be instances where the count of the objects is greater or less than the calculated value of object
count/Job.
4. Include Libraries: Here the user can enter X against the libraries that need to be included during Backup. By default all the libraries will be selected. However the libraries starting with Q except QSYS, QGPL, and QUSRSYS will not be selected. If other such libraries are selected those will be included.
5. Total Object Size: This is the size of all the Libraries (Including the objects inside libraries), which have been selected for Job creation.
6. Total Object Count: This is the count of all the objects, which have been selected for Jobs. This is shown in multiples of 1000.
You have an option to edit exclusions and inclusions on this screen.
Figure 26. - Adjust Include/Exclude List
Upon pressing F6, the above screen appears. When the Include/Exclude count of one or more Jobs exceeds 128, the user is prompted to choose whether to let the Job Creation Tool reshuffle the libraries in order to limit the include/exclude list. By providing ‘Y’ you can let the system reshuffle the include/exclude count. By providing “N” you can come back to the original screen and increase/decrease the number of Jobs in order to bring the include/exclude count to less than 128.
There could be instances where even the system will not be able to make the
Include/Exclude count lesser than 128. In such cases, the user can manually decrease the count of Jobs and retry.
F2: saves the changes made on the current screen. F3: Exit from the screen.
F4: Recalculates the parameters and arrangement of libraries and Jobs.
F5: Replaces the current screen with original arrangement of libraries and screen values.
F6: Creates Include and Exclude list for the Job creation. F7: Previous screen to see previous Jobs
F9: Sorts the Jobs alphabetically.
F10: Sorts the Jobs on size in descending order.
F11: Displays the list of Job names with their include/exclude count.
Notes:
1. The changes in library selection must be saved on the same screen itself.
2. Once the user changes any of the first three parameters mentioned above, pressing F4 recalculates the other two parameters and the arrangement of libraries and Jobs. 3. In case of Include or Exclude count goes beyond 128 the system throws an error. The user can change the input criteria, recalculate and create new list or Job Creation Tool can reshuffle the library/Job selection to reduce the Include/exclude count to 128. 4. Object size/Job when adjusted, is truncated to a lower integer.
e.g. 0.22, 0.45, 0.9 etc. are shown as 0 1.3, 1, 7, 1.9 etc are shown as 1.
5. Object count/Job, when adjusted, is truncated to a lower integer. e.g. 0.3, 0.5, 0.9 etc. are shown as 0
1.2, 1, 5, 1.8 etc are shown as 1.
6. Unless the database is created, the user cannot work with this option.
5.3.3 Include/Exclude List
Figure 27. - Include/Exclude List
The above screen shows the Job names. The Job names are formed with the first character of the include/exclude library names.
Libraries starting with A will be included where the maximum number of libraries starting with an “A” are found and so is the case for all other libraries except “Q”. Libraries
starting with “Q” will not be included as generic Q*. The Exclude list does not support the use of generic library names like A*.
Notes:
1. All the special characters “, @, #, $, / are replaced by $ in Job names.
2. If the user manually deselects all the libraries from the Job, that Job will be listed as blank on this screen.
3. Once the user finalizes the include/exclude list, he/she has to go to “auto Job menu” by pressing F3 thrice.
4. Considering the Backup of future libraries the generic include for A* to Z*, @*, #*, $* and /* except Q* will be added in different Jobs.
