1displayexceptioncontextdisplayexceptioncontext命令用来显示进程异常时的上下文信息.
【命令】displayexceptioncontext[countvalue]【视图】任意视图【缺省用户角色】network-admin【参数】countvalue:表示上下文信息的显示个数,取值范围为1~20,缺省值为1.
【使用指导】当进程发生一次异常,系统会生成一个core文件,还会生成一条上下文信息,用于记录异常进程的ID、生成core文件的时间、core文件存放的位置、栈信息和寄存器信息.
一个core文件对应一条上下文信息,最多可记录的上下文信息数和可记录的core文件数目相同.
【举例】#显示在x86体系32位设备上的异常上下文信息.

14monitorkerneldeadloopenablemonitorkerneldeadloopenable命令用来开启内核线程死循环检测功能.
undomonitorkerneldeadloopenable命令用来关闭内核线程死循环检测功能.
【命令】monitorkerneldeadloopenableundomonitorkerneldeadloopenable【缺省情况】内核线程死循环检测功能处于关闭状态.
【视图】系统视图【缺省用户角色】network-admin【使用指导】在内核态空间中,所有资源都是共享的,多个内核线程之间通过任务调度协调工作.
如果某个内核线程长时间一直占用CPU,就会导致其它内核线程获取不到运行机会,整个系统挂死,我们称这种现象为死循环.
开启内核线程死循环检测功能后,如果系统发现某内核线程在指定时间内一直占用CPU,则判定该内核线程为死循环.
系统会记录一条死循环信息供管理员查询,并自动重启整个系统来解除死循环.
开机后,系统会自动检测内核线程是否发生了死循环,建议用户不要随意配置该命令.
如果确实需要配置,请在H3C工程师的指导下进行,以免引起系统异常.
【举例】#开启内核线程死循环检测功能.

19processcoreprocesscore命令用来开启/关闭进程异常时的生成core文件的功能,以及配置能生成的core文件的最大个数.
【命令】processcore{maxcorevalue|off}{jobjob-id|nameprocess-name}【视图】用户视图【缺省情况】同一进程在首次异常时会生成core文件,后续异常不再生成core文件.
即maxcore的最大数值为1.
【缺省用户角色】network-admin【参数】off:表示关闭进程异常时生成core文件的功能.
maxcorevalue:表示开启进程的core文件生成功能,并配置能生成的core文件的最大个数.
value表示进程能生成的core文件的最大个数,取值范围为1~10,缺省值为1.
nameprocess-name:进程的名称,为1~15个字符的字符串,不区分大小写.
processcore命令的配置对进程下的所有实例有效.
jobjob-id:任务ID,用于唯一标识一个进程,该ID不会随着进程的重启而改变,取值范围为1~2147483647.
【使用指导】开启进程的core文件生成功能,并配置能生成的core文件的最大个数后,进程异常重启一次,就会产生一个core文件并记录进程的异常信息.
如果生成的core文件的数目达到最大值,则不再生成新的core文件.
软件开发和维护人员能够根据core文件的内容来定位异常的原因和异常的位置.
因为生成的core文件会占用系统存储资源,如果用户对某些进程的异常退出不关心,可以关闭这些进程的core文件记录功能.
【举例】#关闭进程routed的core文件生成功能.
processcoreoffnamerouted#开启进程routed的core文件生成功能,并且最多可生成5个core文件.

1displayexceptioncontextdisplayexceptioncontext命令用来显示进程异常时的上下文信息.
【命令】displayexceptioncontext[countvalue]【视图】任意视图【缺省用户角色】network-admin【参数】countvalue:表示上下文信息的显示个数,取值范围为1~20,缺省值为1.
【使用指导】当进程发生一次异常,系统会生成一个core文件,还会生成一条上下文信息,用于记录异常进程的ID、生成core文件的时间、core文件存放的位置、栈信息和寄存器信息.
一个core文件对应一条上下文信息,最多可记录的上下文信息数和可记录的core文件数目相同.
【举例】#显示在x86体系32位设备上的异常上下文信息.

18monitorthreadmonitorthread命令用来显示线程的统计信息.
【命令】monitorthread[dumbtty][iterationnumber]【视图】任意视图【缺省用户角色】network-admin1-31【参数】dumbtty:以哑终端方式显示线程统计信息(即屏幕不支持定时刷新统计信息).
指定该参数时,全部线程的统计信息以CPU使用率降序排列输出到屏幕上.
不指定该参数时,统计信息以交互模式显示,缺省情况下按CPU占用率降序显示前10个线程的统计信息,且每隔5秒更新一次.
iterationnumber:进程统计信息的显示次数,取值范围为1~4294967295.
指定dumbtty参数时number的缺省值为1;不指定dumbtty且不配置number参数时,表示显示次数没有限制,统计信息会一直显示.
【使用指导】不指定dumbtty参数的情况下,统计信息以交互模式显示.
交互模式下,系统会自动计算可显示的线程个数,超过屏幕范围的不作显示.
交互模式下,用户可通过输入表1-12中指定的交互命令字来执行相应的操作.

19processcoreprocesscore命令用来开启/关闭进程异常时的生成core文件的功能,以及配置能生成的core文件的最大个数.
【命令】processcore{maxcorevalue|off}{jobjob-id|nameprocess-name}【视图】用户视图【缺省情况】同一进程在首次异常时会生成core文件,后续异常不再生成core文件.
即maxcore的最大数值为1.
【缺省用户角色】network-admin【参数】off:表示关闭进程异常时生成core文件的功能.
maxcorevalue:表示开启进程的core文件生成功能,并配置能生成的core文件的最大个数.
value表示进程能生成的core文件的最大个数,取值范围为1~10,缺省值为1.
nameprocess-name:进程的名称,为1~15个字符的字符串,不区分大小写.
processcore命令的配置对进程下的所有实例有效.
jobjob-id:任务ID,用于唯一标识一个进程,该ID不会随着进程的重启而改变,取值范围为1~2147483647.
【使用指导】开启进程的core文件生成功能,并配置能生成的core文件的最大个数后,进程异常重启一次,就会产生一个core文件并记录进程的异常信息.
如果生成的core文件的数目达到最大值,则不再生成新的core文件.
软件开发和维护人员能够根据core文件的内容来定位异常的原因和异常的位置.
因为生成的core文件会占用系统存储资源,如果用户对某些进程的异常退出不关心,可以关闭这些进程的core文件记录功能.
【举例】#关闭进程routed的core文件生成功能.
processcoreoffnamerouted#开启进程routed的core文件生成功能,并且最多可生成5个core文件.
