任务调度异常，到时间不执行；

查看syslog发现了问题：

Sep 3 15:48:01 app6G /usr/sbin/cron[30235]: (oracle) RELOAD (crontabs/oracle)
Sep 3 15:48:01 app6G CRON[32285]: User account has expired

因为我在创建用户时指定了passwd -l选项锁定该用户，导致了问题；

取消了锁定，调度正常了。

最后，ubuntu应该安装的包：

sudo apt-get install gcc libaio1 lesstif2 lesstif2-dev make libc6 libc6-i386 libc6-dev-i386 libstdc++5 lib32stdc++6 lib32z1 ia32-libs gcc-multilib

这些内核参数究竟代表什么含义，如何调整这些参数？

共享内存：

可以通过ipcs -lm命令查看目前系统共享内存的参数限制：

# ipcs -lm

—— Shared Memory Limits ——–
max number of segments = 4096
max seg size (kbytes) = 1048576
max total shared memory (pages) = 2097152
min seg size (bytes) = 1

这里涉及到3个于共享内存相关的参数：SHMMAX，SHMMNI，SHMALL

SHMMAX

• 含义：单个共享内存段最大字节数
• 设置：比SGA略大
• 查看：cat /proc/sys/kernel/shmmax

$ cat /proc/sys/kernel/shmmax
1073741824

• 修改：

sysctl -w kernel.shmmax=1073741824
echo “kernel.shmmax=1073741824″ >> /etc/sysctl.conf

SHMMNI

• 含义：共享内存段最大个数
• 设置：至少4096
• 查看：cat /proc/sys/kernel/shmmni

# cat /proc/sys/kernel/shmmni
4096

• 修改：

# sysctl -w kernel.shmmni=4096
# echo “kernel.shmmni=4096″ >> /etc/sysctl.conf

SHMALL

• 含义：系统中共享内存页总数
• 设置：至少ceil(shmmax/PAGE_SIZE)；ORACLE DOC 默认值：2097152*4096=8GB
• 查看：cat /proc/sys/kernel/shmall

$ getconf PAGE_SIZE
4096

# cat /proc/sys/kernel/shmall
2097152

• 修改：

# sysctl -w kernel.shmall=2097152
# echo “kernel.shmall=2097152″ >> /etc/sysctl.conf

信号量：

当前系统信号量限制：

oracle@lab-rd-01:~$ ipcs -ls

—— Semaphore Limits ——–
max number of arrays = 128
max semaphores per array = 250
max semaphores system wide = 32000
max ops per semop call = 100

SEMMSL

• 含义：每个信号量set中信号量最大个数
• 设置：最小250；对于processes参数设置较大的系统建议设置为processes+10
  

SEMMNI

• 含义：linux系统信号量set最大个数
• 设置：最少128

SEMMNS

• 含义：linux系统中信号量最大个数
• 设置：至少32000；SEMMSL * SEMMNI

SEMOPM

• 含义：semop系统调用允许的信号量最大个数
• 设置：至少100；或者等于SEMMSL

查看信号量设置：cat /proc/sys/kernel/sem

order：SEMMSL, SEMMNS, SEMOPM, SEMMNI

oracle@lab-rd-01:~$ cat /proc/sys/kernel/sem
250    32000    100    128

修改：

sysctl -w kernel.sem=”250 32000 100 128″
echo “kernel.sem=250 32000 100 128″ >> /etc/sysctl.conf

ORACLE提供了sysresv工具管理共享内存以及信号量，操作系统级别可以通过ipcs管理。

在设置别名的过程中有一个小插曲：
用/etc/profile定义别名，在gnome中进入终端后，不能正常使用别名，进入命令行，可以正常读取别名设置；
应该是由于gnome中调用了gnome-terminal导致了问题，只好修改/etc/bash.bashrc来实现。
