4. Confirm the change with another INFO command. For example:

If you need to reverse this operation, repeat the ALTER command using the original value.
Changing the System TLE Limit Attribute
This procedure lets you specify the TLE limit attribute. As of the J06.09, H06.20, and G06.32.01
RVUs, you can configure a limit on the number of TLEs (Time List Elements) that can be allocated
by a process. For previous G, H, and J-series RVUs, there was no such limit and an errant application
could consume all, or nearly all, the TLEs.
The default TLE limit is the maximum number of TLEs per CPU:
• For G-series systems, the maximum number of TLEs per CPU is 3600.
• For H and J-series systems, the maximum number of TLEs per CPU is 20000.
For more information about the TLE_LIMIT attribute of the ALTER SUBSYS command, see
TLE_LIMIT (page 95).
1. As a precaution, save the current configuration file with an SCF SAVE command (documented
in the SCF Reference Manual for G-Series RVUs or the SCF Reference Manual for J-Series and
H-Series RVUs.
For example, use this command to save the current configuration file in a file at the location
$SYSTEM.ZSYSCONF.CONF0106:
-> SAVE CONFIGURATION 1.6
2. View the current settings for the attribute TLE Limit with an SCF INFO command:
-> ASSUME SUBSYS $ZZKRN
-> INFO
NONSTOP KERNEL - Info SUBSYS \EAST.$ZZKRN
Current Settings
*DAYLIGHT_SAVING_TIME ................ USA66
*NONRESIDENT_TEMPLATES................ $SYSTEM.SYSTEM.NRTNEW
*POWERFAIL_DELAY_TIME................. 30
*RESIDENT_TEMPLATES................... $SYSTEM.SYSTEM.TNEW
SUPER_SUPER_IS_UNDENIABLE............ OFF
*SYSTEM_NAME.......................... \EAST
*SYSTEM_NUMBER........................ 254
SYSTEM_PROCESSOR_TYPE ............... NSR-W
*TIME_ZONE_OFFSET..................... -8:00
*TNSMISALIGN.......................... FAIL
*DESTINATION_CONTROL_TABLE............ SMALL
*TLE_LIMIT............................ 2000
*AUTO_RETRY_ON_ERROR_654.............. OFF
3. Change the TLE Limit attribute using ALTER command. For example, to change the TLE limit to
3000:
-> ALTER, TLE_LIMIT 3000
This change takes effect immediately.
4. Confirm the change with another INFO command. For example:
-> INFO
If you need to reverse this operation, repeat the ALTER command using the original value.
