UNIX 506的CRON問(wèn)題

alanlql

不知道是506的問(wèn)題,還是我的服務(wù)器的問(wèn)題,我服務(wù)器上的CRON一直不正常,有時(shí)能按要求運(yùn)行指定程序,有時(shí)則沒(méi)有按時(shí)啟動(dòng)指定程序.如:

CRON文件內(nèi)容:
11 9-16 * * 1-5 /usr/alanlql/test1.p >;/tmp/t1.log 2>;&1
0 20 * * * /usr/alanlql/test2.p >;/tmp/t2.log 2>;&1

test1.p的內(nèi)容:
echo "test1.p   --->; \c"
date

test2.p的內(nèi)容:
echo "test2.p   --->; \c"
date

經(jīng)查,t1.log中有時(shí)一天有一條記錄,有時(shí)有4條,而且支行的時(shí)點(diǎn)也不一樣.而昨天晚上沒(méi)有運(yùn)行test2.p
不知是否有人和我碰到同樣的問(wèn)題.或者是否有人原幫我試一下,找找是什么原因.謝謝了.

我加了一行:
* * * * * date >;>; /usr/alanlal/test.log
結(jié)果test.log中的內(nèi)容這個(gè)樣子.

各位,真的沒(méi)人知道嗎?

commdos

不會(huì)啊，cron應(yīng)該沒(méi)有你說(shuō)的問(wèn)題。你向crontabs目錄的用戶(hù)文件中加入安排任務(wù)后一種方法重啟系統(tǒng)，或者sh /etc/rc2.d/P75cron stop再
sh /etc/rc2.d/P75cron start。

alanlql

我是將
* * * * * date >;>; /usr/alanlal/test.log
和第一貼的內(nèi)容加入到/usr/alanlql/t_cron文件中,再在/usr/alanlql/目錄下用命令
crontab t_cron
啟用新的cron任務(wù)的.
我以root用戶(hù)用crontab -l >;t_root,再在t_root中加上
* * * * * date >;>; /usr/alanlal/test.log
一行,再用crontab t_root啟用,結(jié)果也一樣有少了的日志行.
我在505下試就沒(méi)這個(gè)問(wèn)題.

我前幾天問(wèn)過(guò)思科中國(guó)公司了,因?yàn)槭荴eon2.0G/1G /M1的配置,我已打了rs506a,oss648a二個(gè)包,oss642a的文檔上說(shuō),506a 以上的版不用再打這個(gè)包了,思科的工程也是說(shuō)和這個(gè)沒(méi)關(guān)系.

oss642a.ltr是這么寫(xiě)的:

Dear Caldera Customer,


Support Level Supplement (SLS) OSS642A, the Cron Supplement, addresses
various problems in the cron daemon, including the "job sometimes runs
twice" problem.

你有沒(méi)有試過(guò)?我的一個(gè)朋友試了一下,好象在有超線(xiàn)程的PC上裝UNIX 506也有CRON問(wèn)題,我因?yàn)槭巧�產(chǎn)環(huán)境,不能隨便試,而且我也沒(méi)有其他帶超線(xiàn)程的機(jī)子.
