Additional Information:
-
Previous to the PTFs being applied the QTVDEVICE jobs are submitted with a compare value of QCMDI. If the performance issues occurred, the circumvention noted above was to add a Routing Entry with a compare value for QCMDI that will reference a Class with a higher run priority. A drawback to this is that other jobs, the Pass-through server for example, are submitted to the QSYSWRK subsystem with a compare value of QCMDI. So the QCMDI Routing Entry affected more than just Telnet.
-
Mindful of the potential side effects of the first circumvention, a unique compare value of TELNETD was added to the QTVDEVICE job submission via PTF. This allows the run priority of the Telnet QTVDEVICE jobs to be changed without affecting any other programs. A real consideration with these PTFs, which are on the current Cumulative Packages, is that if you previously had added the QCMDI Routing Entry to address this issue, and the new Routing Entry is not added, the same performance lags that were experienced before will reappear.
-
If you had previously added the QCMDI Routing Entry at sequence number 2517, the recommendation is to remove that Routing Entry and add the one for TELNETD at sequence number 2517. Because in future releases of OS/400 the install of TCP/IP Connectivity Utilities will add the Routing Entry for TELNETD at sequence number 2517. If you still want jobs that are submitted to the QSYSWRK subsystem with a compare value of QCMDI to run at a priority other than 50, then add that Routing Entry back at any
available sequence number.
-
For tuning the System performance further, the run priority can be customized by replacing the QSYSCLS20 class with a different class, either system provided or user created, that references a different run priority. And with the new PTFs applied, that change will only affect the Telnet server jobs.
Choose option 1 and type the options as you see them on the image below. Source file is the file where the code will be stored. Member is the name of member we're creating.
After typing what you see on the image press Enter. Always check what you've done before pressing Enter, because after that you can only alter the screen by manipulating its code. You can also exit the record editing without saving your work, but then you'll lose all you've done since you last opened the record for editing.
So that you don't overlap the records you can choose to visualize other records in the menu. You can see that the status of the BOTTOM record is “In Use” which means it is the one currently being edited. You can select at most 3 records to visualize. To do so place numbers 1 to 3 on the records you want. Select the TOP record and press Enter.
The names of the selected fields appear on the bottom of the screen. Don't forget you are only “drawing” on the record in use. The other records only help you place your elements on the right place.
This screen appears. Place an 'Y' in the Colors option. We're going to change the color of the characters.
