You can use the Java Platform,
Enterprise Edition (Java EE)
command line syntax for the launchClient tool for WebSphere® Application Server.
Important: All
users who run commands from a specific profile must have authority
to modify files that are created by other users that use the same
profile. Otherwise, you might see a permission denied error in the
log files. To avoid this issue, consider one of the following policies:
Use specific profiles for distinct user
authorities
- Always use the same user for all of the commands that are run
in a given profile
- Ensure that all users of a specific profile belong to the same
group. In addition, ensure that each user of a group has the read
and write authority to the files that are created by other members
in the same profile.
The following example illustrates the command line
invocation syntax for the launchClient tool:
launchClient [-profileName pName | -JVMOptions options | -help | -?] userapp [-CCname=value] [app args]
where
- userapp is the path and the name of the EAR
file that contains the application client.
- -CCname=value is the client container name-value
pair parameter. See the client container parameters section, for supported
name-value pair arguments.
- app args are arguments that pass to the application
client.
- -profileName defines the profile of the Application
Server process in a multi-profile installation. The -profileName option
is not required for running in a single profile environment or in
an Application Clients installation.
- -JVMOptions is a valid Java standard or nonstandard option string,
except -cp or -classpath. Insert
quotation marks around the string.
- -help, -? prints the usage information.
The first parameter must be -help, -? or
contain no parameter at all. The -profileName pName and -JVMOptions options
are optional parameters. If used, they must appear before the <userapp> parameter.
All other parameters are optional and can appear in any order after
the userapp parameter. The Java EE Application client run time ignores
any optional parameters that do not begin with a -CC prefix
and passes those parameters to the application client.
Client container parameters
Supported arguments
include:
- -CCadminConnectorHost
- Specifies the host name of the server from which configuration
information is retrieved.
The default is the value of the -CCBootstrapHost parameter
or the value, your.server.name, if the -CCBootstrapHost parameter
is not specified.
- -CCadminConnectorPort
- Indicates the port number for the administrative client function
to use. The default value is 8880 for SOAP connections
and 2809 for Remote Method Invocation (RMI) connections.
- -CCadminConnectorType
- Specifies how the administrative client connects to the server.
Specify RMI to use the RMI connection type, or specify SOAP to
use the SOAP connection type. The default value is SOAP.
- -CCadminConnectorUser
- Administrative clients use this user name when a server requires
authentication. If the connection type is SOAP, and security is enabled
on the server, this parameter is required.
- -CCadminConnectorPassword
- The password for the user name that the -CCadminConnectorUser parameter
specifies.
- -CCaltDD
- The name of an alternate deployment descriptor file. This parameter
is used with the -CCjar parameter to specify the
deployment descriptor to use. Use this argument when a client JAR
file is configured with more than one deployment descriptor. Set the
value to null to use the client JAR file standard
deployment descriptor.
- -CCBootstrapHost
- The name of the host server you want to connect to initially.
The format is: your_server_of_choice.com
- -CCBootstrapPort
- The server port number. If you do not specify this argument, the WebSphere Application Server default value
is used.
- -CCclassLoaderMode
- Specifies the class loader mode. If PARENT_LAST is specified,
the class loader loads classes from the local class path before delegating
the class loading to its parent. The classes loaded for the following
are affected:
- Classes defined for the Java EE
application client
- Resources defined in the Java EE
application
- Classes specified on the manifest of the Java EE client JAR file
- Classes specified using the -CCclasspath option
If PARENT_LAST is not specified, then the default mode, PARENT_FIRST,
causes the class loader to delegate the loading of classes to its
parent class loader before attempting to load the class from its local
class path.
- -CCclasspath
- A class path value. When you launch an application, the system
class path is used. If you want to access classes that are not in
the EAR file or part of the system class paths, specify the appropriate
class path here. Multiple paths can be concatenated.
- -CCD
- Use this option to have the WebSphere Application Server set the specified
system property during initialization. Do not use the equals (=) character
after the -CCD. For example: -CCDcom.ibm.test.property=testvalue.
You can specify multiple -CCD parameters. The general format
of this parameter is -CCD<property key>=<property value>. For
example, -CCDI18NService.enable=true.
- -CCdumpJavaNameSpace
- Controls generation of a dump of the java: name space for the
application that is launched, which can be used for debugging purposes.
A value of true generates a dump in short format, and includes
the name and object type for each binding. A value of long generates
a dump in long format, and includes additional information for each
binding over short format, such as the local object type and string
representation of the local object. The default value is false,
and does not generate a dump.
- -CCexitVM
- Use this option to have the WebSphere Application Server call the System.exit() method
after the client application completes. The default is false.
- -CCinitonly
- Use this option to initialize application client run time for
ActiveX application clients without launching the client application.
The default is false.
- -CCjar
- The name of the client Java Archive
(JAR) file that resides within the EAR file for the application you
wish to launch. Use this argument when you have multiple client JAR
files in the EAR file.
- -CCpropfile
- Indicates the name of a properties file that contains launchClient
properties. Specify the properties without the -CC prefix
in the file, with the exception of the securityManager, securityMgrClass
and securityMgrPolicy properties. See the following example: verbose=true.
- -CCproviderURL
- Provides bootstrap server information that the initial context
factory can use to obtain an initial context. WebSphere Application Server initial context
factory can use either a Common Object Request Broker Architecture
(CORBA) object URL or an Internet Inter-ORB Protocol (IIOP) URL. CORBA
object URLs are more flexible than IIOP URLs and are the recommended
URL format to use. This value can contain more than one bootstrap
server address. This feature can be used when attempting to obtain
an initial context from a server cluster. You can specify bootstrap
server addresses, for all servers in the cluster, in the URL. The
operation will succeed if at least one of the servers is running,
eliminating a single point of failure. The address list does not process
in a particular order. For naming operations, this value overrides
the -CCBootstrapHost and -CCBootstrapPort parameters.
A CORBA object URL specifying multiple systems is illustrated in the
following example:
-CCproviderURL=corbaloc:iiop:myserver.mycompany.com:9810,:mybackupserver.mycompany.com:2809
This
value is mapped to the java.naming.provider.url system property.
- -CCsecurityManager
- Enables and runs the WebSphere Application Server with a security
manager. The default is disable.
- -CCsecurityMgrClass
- Indicates the fully qualified name of a class that implements
a security manager. Only use this argument if the -CCsecurityManager parameter
is set to enable. The default is java.lang.SecurityManager.
- -CCsecurityMgrPolicy
- Indicates the name of a security manager policy file. Only use
this argument if the -CCsecurityManager parameter
is set to enable. When you enable this parameter, the java.security.policy system
property is set. The default is app_server_root/properties/client.policy.
- -CCsoapConnectorPort
- The Simple Object Access Protocol (SOAP) connector port. If you
do not specify this argument, the WebSphere Application Server default value
is used.
- -CCtrace
- Use this option to obtain debug trace information. You might need
this information when reporting a problem to IBM® customer support. The default is false.
For more information, read the Enabling trace topic.
- -CCtracefile
- Indicates the name of the file to which trace information is written.
The default is to write output to the console.
- -CCtraceMode
- Specifies the trace format to use for tracing. If the valid value, basic,
is not specified the default is advanced. Basic tracing format is
a more compact form of tracing.
For more
information on basic and advanced trace formatting, refer to the Interpreting
trace output topic.
- -CCverbose
- This option displays additional information messages. The default
is false.
If you are using an EJB client application with security
enabled, edit the sas.client.props file, which
is located in the profile_root/properties directory.
Within the file, change the com.ibm.CORBA.loginSource value
to none.
For more information on the sas.client.props utility,
refer to the Manually encoding passwords in properties files and the
PropFilePasswordEncoder command reference topics.
- RMI connection with security. Used with the EJB and administrative
client application.
- Using Jacl:
wsadmin -conntype RMI -port rmiportnumber -user userid
-password password
Using Jython:
wsadmin -lang jython -conntype RMI -port rmiportnumber -user userid
-password password
rmiportnumber for
your connection displays in the administrative console as BOOTSTRAP_ADDRESS.
Attention: On the AIX®,
HP-UX, Linux, IBM i, Solaris, and z/OS® operating systems, the use of -password
option may result in security exposure as the password information
becomes visible to the system status program, such as ps command,
which can be invoked by other users to display all of the running
processes. Do not use this option if security exposure is a concern.
Instead, specify user and password information in the
soap.client.props file
for SOAP connector or
sas.client.props file for
RMI connector. The
soap.client.props and
sas.client.props files
are located in the properties directory of your
WebSphere Application Server profile.
If
Kerberos (KRB5) is enabled for administrative authentication, the
authentication target supports BasicAuth and KRB5. To use KRB5, update
the sas.client.props, soap.client.props,
and ipc.client.props files, according to the
connector type.
Attention: When using Kerberos
authentication, the user password does not flow across the wire. A
one-way hash of password is used to identify the client.
