正如你所知,有时候我们有必要终止所有的Oracle过程(process)或者指定的一组Oracle过程。当数据库“锁定”而你无法进入Server Manager来“温柔”的终止数据库时,就可以用UNIX中的kill命令来终止所有的Oracle过程——这是kill命令的常见用途之一。

当你需要终止一个UNIX服务器上的一个Oracle实例(instance)时,执行下面的步骤:

终止与ORACLE_SID有关的所有Oracle过程。

用ipcs –pmb命令来识别所有占用的RAM内存片断。

用ipcrm -m 命令来从UNIX中释放占用的RAM内存。

只对Non-AIX:用ipcs -sa命令来显示占用标记,,用ipcrm –s命令来释放该实例的占用标记。

创建单一命令来终止与挂起(hung)的数据库实例有关的Oracle过程是很简单的。在下面的例子之中,我们用ps指令来识别Oracle过程,然后用 awk程序来获取Oracle过程的过程ID(process ID,PID)。然后,我们把过程ID输入到UNIX的kill命令之中。

root> ps -ef|grep ora_| \
grep -v grep|awk '{print $2}'|xargs -i kill -9 {}

在终止所有Oracle过程之后,我们可以用ipcs –pmb指令来检查占用的内存并清除数据库所占用的内存。我们首先显示出数据库服务器上所有占用内存:

root> ipcs -pmb

IPC status from /dev/kmem as of Mon Sep 10 16:45:16 2001
T ID KEY MODE OWNER GROUP SEGSZ CPID LPID
Shared Memory:
m 24064 0x4cb0be18 --rw-r----- oracle dba 28975104 1836 23847
m 1 0x4e040002 --rw-rw-rw- root root 31008 572 572
m 2 0x411ca945 --rw-rw-rw- root root 8192 572 584
m 4611 0x0c6629c9 --rw-r----- root root 7216716 1346 23981
m 4 0x06347849 --rw-rw-rw- root root 77384 1346 1361

在这里,我们看到Oracle只拥有一个ID=24064的RAM内存。下面的命令将会释放这个内存片断:

root> ipcrm -m 24064

Declare the cursor in the USING clause so that it automatically closes when the associated PL/SQL variable is closed. Use exception handling to ensure that the cursor is closed in any exception situation. Use the connection pool to automatically close the cursor. Disable automatic submission and delay cursor closing.

How to solve garbled code in oracle How to solve garbled code in oracle Apr 11, 2025 pm 10:09 PM

Oracle garbled problems can be solved by checking the database character set to ensure they match the data. Set the client character set to match the database. Convert data or modify column character sets to match database character sets. Use Unicode character sets and avoid multibyte character sets. Check that the language settings of the database and client are correct.
