To start and stop AdminServer and the managed servers, we use a Jython (Python) script. It is on purpose made simple, but on production systems there should be more error handling, and also more efficient connection handling (i.e., check if there is a connection to NodeManager and/or AdminServer and reuse the connection if there is one active). Instead of calling the script below once for each server that we want to start, this script and the startall.sh script could be changed to give a list of servers to start, not just one and one as it is now.
wls.py
1import sys
2
3def startAdmin():
4 print 'Starting AdminServer'
5 nmConnect(userConfigFile=nmUserFile, userKeyFile=nmKeyFile, host=nmHost, port=nmPort, domainName=domain, domainDir=domainPath, nmType=nmType)
6 nmStart('AdminServer')
7 nmDisconnect()
8 return
9
10def stopAdmin():
11 print 'Stopping AdminServer'
12 connect(userConfigFile=wlsUserFile, userKeyFile=wlsKeyFile, url=adminUrl)
13 shutdown('AdminServer', force='true')
14 disconnect()
15 return
16
17def startManaged(managed):
18 print 'Starting ', managed
19 connect(userConfigFile=wlsUserFile, userKeyFile=wlsKeyFile, url=adminUrl)
20 start(managed)
21 disconnect()
22return
23
24def stopManaged(managed):
25 print 'Stopping ', managed
26 connect(userConfigFile=wlsUserFile, userKeyFile=wlsKeyFile, url=adminUrl)
27 shutdown(managed, force='true')
28 disconnect()
29return
30
31if ((len(sys.argv) < 2) | (len(sys.argv) > 3)):
32 print ' Wrong number of arguments'
33elif (sys.argv[1] == 'startadmin'):
34 startAdmin()
35elif (sys.argv[1] == 'stopadmin'):
36 stopAdmin()
37elif (sys.argv[1] == 'start'):
38 startManaged(sys.argv[2])
39elif (sys.argv[1] == 'stop'):
40 stopManaged(sys.argv[2])
Full path for wlst.sh (under wlserver/common/bin) and wls.py must be given, unless they are in $PATH
startall.sh
1wlst.sh -loadProperties config.properties -skipWLSModuleScanning wls.py startadmin
2wlst.sh -loadProperties config.properties -skipWLSModuleScanning wls.py start ms1
stopall.sh
1wlst.sh -loadProperties config.properties -skipWLSModuleScanning wls.py stop ms1
2wlst.sh -loadProperties config.properties -skipWLSModuleScanning wls.py stopadmin
adminUrl must point to the AdminServer (often a VIP address) while nmHost points to the local NodeManager.
config.properties
1adminUrl=t3://wls12c.dev.sysco.no:7001
2nmHost=wls12c.dev.sysco.no
3nmPort=5556
4nmUserFile=/u01/app/oracle/config/nmUserFile
5nmKeyFile=/u01/app/oracle/config/nmKeyFile
6nmType=plain
7wlsUserFile=/u01/app/oracle/config/wlsUserFile
8wlsKeyFile=/u01/app/oracle/config/wlsKeyFile
9domain=mydomain
10domainPath=/u01/app/oracle/user_projects/domains/mydomain
Before running this command (deprecated in 12c, but still works in 12.1.3), you must source setDomainEnv.sh for the domain you are using.
Encrypt username and password (11g)
1java weblogic.Admin -username nodemanager -userconfigfile /u01/app/oracle/config/nmUserFile -userkeyfile /u01/app/oracle/config/nmKeyFile STOREUSERCONFIG
To run this command, you must start WLST in interactive mode. First you have to source setDomainEnv.sh, then start WLST
Encrypt username and password (12c)
1java weblogic.WLST
2wls:/offline> nmConnect( ‘nodemanager','welcome1','localhost',5556,'mydomain', '/u01/app/oracle/user_projects/domains/mydomain', 'plain')
Encrypt username and password for Node Manager
1wls:/mydomain/serverConfig> storeUserConfig(
2'/u01/app/oracle/config/nmUserFile','/u01/app/oracle/config/nmKeyFile', 'true')
Encrypt username and password for WebLogic admin user
1wls:/mydomain/serverConfig> connect('weblogic', 'welcome1', 't3://wls12c.dev.sysco.no:7001')
2wls:/mydomain/serverConfig> storeUserConfig(
3'/u01/app/oracle/config/wlsUserFile','/u01/app/oracle/config/wlsKeyFile','false')
This is not based on the script from the 12c documentation http://docs.oracle.com/middleware/1213/wls/NODEM/java_nodemgr.htm#BABJIDFD. One important difference is that this script starts NodeManager with user oracle, while the script in the documentation starts NodeManager as root, which is not recommended.

For both the nodemanager and the weblogic scripts, they must be made runnable (chmod 0755) and activated (chkconfig --add) before they will be used next time the server starts or stops.
