cronjob 數目上線的問題

[watermelonyu]

在 tru64 5.1B 上, cron 同時可以處理的 job 可以有幾個呢 ??



因為我們有個 case 因為 AP 的異常行為導致同一個 AP 一直啟動 cronjob , 因而其他 job 卻無法執行 !



像這種情況 , 如何去防範與偵測才好呢 ??



希望高手幫我指點一下 !

Thanks a lot!

Hi Chia,



The default (maximum) cronjob queue length is set to "25".

See the configuration file in /var/adm/cron/queuedefs.



# tail /var/adm/cron/queuedefs

#

# max_jobs=j

# log=l

# where

# j - maximum no. of active jobs over all the queues at any one time

# (default 25 jobs)

# l - logging level of messages to log file (default Full logging)

# None = 0, Low = 1 , Medium = 2, High = 3, Full = 4

max_jobs=25

log=4



Please change the max_jobs from 25 to 100 then restarting the

process "cron". It will handle the maximum 100 cron jobs at the same time.

Please solving this abnormal AP first, otherwise the cron queue will not enough to run.
