有用的weblogic.Admin
作为一名现场技术顾问，通常客户在现场服务器上安装WLST后，我就开始工作了。但是在WLS 9之前的版本中没有WLST，所以我有时只好使用weblogic.Admin以及VI和Bash。
这里要说的是我用来从WLS转储EJB数据的一个Bash脚本。您根本不需要Bash，它只是一个较长的命令行的包装器。
#!/bin/bash
# ejbdump.sh
#
# author: Hussein Badakhchani
# date: 29 September 2005
# description: This scrip uses the weblogic.Admin tool to dump all data \
# relating to a EJBMBeans
# processname: ejbdump
# info: Make sure your WebLogic environment is set up correctly. \
# Run setEnv.sh before using ejbdump
prog=ejbdump
if [ ! $# == 4 ]; then
echo
echo "Usage: $0 url username password command_file"
echo
echo "e.g. ejbdump myhost:7001 myuser mypassword commands.txt"
exit
fi
url=$1
username=$2
password=$3
command_file=$4
# Check for the existence of the command file.
if [ ! -f "$command_file" ]
then
echo
echo "Command file: $command_file not found!"
echo "Please proivde the correct path to this file and ensure you have the \
correct privledges associated with it."
exit $E_NOTFOUND
fi
java -cp $CLASSPATH weblogic.Admin -adminurl $url -username $username \
-password $password BATCHUPDATE -batchFile $command_file \
-continueOnError -batchCmdVerbose
该脚本运行weblogic.Admin类，它在$command_file中执行大量的命令，这里是：commands.txt。
get -pretty -type EJBCacheRuntime
get -pretty -type EJBComponentRuntime
get -pretty -type EJBLockingRuntime
get -pretty -type EJBPoolRuntime
get -pretty -type EJBRuntime
get -pretty -type EJBTransactionRuntime
get -pretty -type EntityCacheCumulativeRuntime
get -pretty -type EntityCacheCurrentStateRuntime
get -pretty -type EntityCacheRuntime
get -pretty -type EntityEJBRuntime
-type参数全都是MBean，我从WLS 8.1 API javadocs获得这些。注意，要在名称中去掉“MBean”，才是正确的参数名。
使用命令行运行上面的脚本：
[husseinb@lap1 bea]$ ./ejbdump lap3:7001 weblogic weblogic commands.txt
当然也可以将参数硬编码到脚本中。当在WLS附带的示例域中运行时，输出如下：
Executing command: get -pretty -type EntityCacheRuntime
No MBeans found
Error executing command in batch file commands.txt at line number: 9
Executing command: get -pretty -type EntityEJBRuntime

输出非常罗嗦，如果您要研究特定的bean，可以使用它的名称（从上一个脚本的输出中获得）来指示weblogic.Admin，例如：
java -cp $CLASSPATH weblogic.Admin -url lap3:7001 -username weblogic \
-password weblogic GET -pretty -mbean \
examples:ApplicationRuntime=examplesServer__appsdir_ejb20_basic_containerManaged_ear,
EJBComponentRuntime=examplesServer__appsdir_ejb20_basic_containerManaged_ear_ejb20_basic_containerManaged.jar,
Location=examplesServer,
Name=examplesServer__appsdir_ejb20_basic_containerManaged_ear_ejb20_basic_containerManaged.jar_containerManaged,
ServerRuntime=examplesServer,Type=EJBTransactionRuntime
最后，我要说明一下，虽然BEA的WLS 7和8.1版没有附带WLST联机版，但是它们仍然支持它。
