针对Oracle10g EM乱码之快速解决方法
一直没怎么用10g的EM工具,今天打开来看看,发现也有相传已久的乱码问题.网上也流传着N种解决方案,仔细看一下,其实这个问题很好解决.
如果安装时,我们系统环境变量设置的是中文环境,那么就不会有这个问题.这个问题根本原因在于安装时,JDK/JRE字符集的自动选择.
在 $ORACLE_HOME/jdk/jre/lib 和 $ORACLE_HOME/jre/1.4.2/lib/ 目录下都有多种字符集字体配置文件:
<ccid_code>[oracle@danaly ~]$ cd $ORACLE_HOME/jdk/jre/lib[oracle@danaly lib]$ ls font*zh_CN*font.properties.zh_CN.Redhat font.properties.zh_CN.Redhat2.1 font.properties.zh_CN.Sun font.properties.zh_CN_UTF8.Sun[oracle@danaly lib]$ cd $ORACLE_HOME/jre/1.4.2/lib/[oracle@danaly lib]$ ls font*zh_CN*font.properties.zh_CN.Redhat font.properties.zh_CN.Redhat2.1 font.properties.zh_CN.Sun font.properties.zh_CN_UTF8.Sun</ccid_code>
我们只要用合适的中文字符集文件替换缺省文件即可,我选择使用font.properties.zh_CN.Redhat来替换缺省字体定义文件:
[oracle@danaly lib]$ cp font.properties.zh_CN.Redhat font.properties
替换之后需要清理一下Cache,重启EM即可.
Cache路径通常位于:
$ORACLE_HOME/oc4j/j2ee/oc4j_applications/applications/em/em/cabo/images/cache/zhs
清除所有gif文件即可.然后重新启动EM:
<ccid_code>[oracle@danaly zhs]$ emctl stop dbconsoleTZ set to PRCOracle Enterprise Manager 10g Database Control Release 10.2.0.1.0 Copyright (c) 1996, 2005 Oracle Corporation.

How to solve the problem of closing oracle cursor
Apr 11, 2025 pm 10:18 PM
The method to solve the Oracle cursor closure problem includes: explicitly closing the cursor using the CLOSE statement. Declare the cursor in the FOR UPDATE clause so that it automatically closes after the scope is ended.
