根据评论编辑:
方法一:
- 打开 setDomainEnv.cmd 并
export SERVER_NAME
在 Linux 或set SERVER_NAME
Windows 中搜索。跳到下一行(即跳过当前和下一行)
在当前行,插入:
customServerList="server1,server2" #this serverList should be taken as input
isCurrServerCustom=$(echo ${customServerList} | tr ',' '\n' | grep ${SERVER_NAME} | wc -l)
if [ $isCurrServerCustom -gt 0 ]; then
# add customJavaArg
JAVA_OPTIONS="-Dmy.property=${USERPROFILE}/someDir/someJar.jar"
fi
- 保存 setDomainEnv.sh 文件并重新启动服务器
请注意,我只给出了 Linux 的逻辑,对于 Windows,可以使用类似的逻辑,但使用批处理脚本语法。
方法二:
假设 domain 已经安装并且用户提供了-Dmy.property
需要添加 JVM 参数的服务器列表。Jython 脚本(使用 wlst.sh 执行)。WLST 参考。
用法:wlst.sh script_name props_file_location
import os
from java.io import File
from java.io import FileInputStream
# extract properties from properties file.
print 'Loading input properties...'
propsFile = sys.argv[1]
propInputStream = FileInputStream(propsFile)
configProps = Properties()
configProps.load(propInputStream)
domainDir = configProps.get("domainDir")
# serverList in properties file should be comma seperated
serverList = configProps.get("serverList")
# The current machine's logical name as mentioned while creating the domain has to be given. Basically the machine name on which NM for current host is configured on.
# This param may not be required as an input if the machine name is configured as same as the hostname , in which case , socket module can be imported and socket.getHostName can be used.
currMachineName = configProps.get("machineName")
jarDir = os.environ("USERPROFILE")
argToAdd = '-Dmy.property=' + jarDir + File.separator + 'someDir' + File.separator + 'someJar.jar'
readDomain(domainDir)
for srvr in serverList.split(",") :
cd('/Server/' + srvr)
listenAddr = get('ListenAddress')
if listenAddr != currMachineName :
# Only change current host's servers
continue
cd('/Server/' + srvr + '/ServerStart/' + srvr)
argsOld = get('Arguments')
if argsOld is not None :
set('Arguments', argsOld + ' ' + argToAdd)
else:
set('Arguments', argToAdd)
updateDomain()
closeDomain()
# now restart all affected servers (i.e serverList)
# one way is to connect to adminserver and shutdown them and then start again
必须从要部署托管服务器的所有主机运行脚本,以便在 JVM 参数中具有主机特定值“USERPROFILE”。
BTW, to answer your question in a line : looks like the JVM arguments have to be supplied with the literal text eventually. But looks like WLS doesn't translate the environment variables if provided as JVM arguments. It gives an impression that it is translating when its done from startWebLogic.cmd (ex: using %DOMAIN_HOME% etc.) but its the shell/cmd executor that translates and then starts the JVM.
