This command shows the threads (dump of stack trace), classes and memory for a given target instance, including the Domain Administration Service. This command works only with the application server instance processes. This command replaces the traditional techniques like sending ctrl+break or kill -3 signals to application server processes. The command will not work if the target server instance is not running.
Indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well-formatted data for consumption by a script. Default is false.
Setting to true will echo the command line statement on the standard output. Default is false.
If set to true (default), only the required password options are prompted.
The machine name where the domain administration server is running. The default value is localhost.
The HTTP/S port for administration. This is the port to which you should point your browser in order to manage the domain. For example, http://localhost:4848.
The default port number for Platform Edition is 4848. The default port number for Enterprise Edition is 4849.
If set to true, uses SSL/TLS to communicate with the domain administration server.
The authorized domain administration server administrative username.
If you have authenticated to a domain using the asadmin login command, then you need not specify the --user option on subsequent operations to this particular domain.
The ––passwordfile option specifies the name of a file containing the password entries in a specific format. The entry for the password must have the AS_ADMIN_ prefix followed by the password name in uppercase letters.
For example, to specify the domain administration server password, use an entry with the following format: AS_ADMIN_PASSWORD=password, where password is the actual administrator password. Other passwords that can be specified include AS_ADMIN_MAPPEDPASSWORD, AS_ADMIN_USERPASSWORD, and AS_ADMIN_ALIASPASSWORD.
All remote commands must specify the admin password to authenticate to the domain administration server, either through ––passwordfile or asadmin login, or interactively on the command prompt. The asadmin login command can be used only to specify the admin password. For other passwords, that must be specified for remote commands, use the ––passwordfile or enter them at the command prompt.
If you have authenticated to a domain using the asadmin login command, then you need not specify the admin password through the ––passwordfile option on subsequent operations to this particular domain. However, this is applicable only to AS_ADMIN_PASSWORD option. You will still need to provide the other passwords, for example, AS_ADMIN_USERPASSWORD, as and when required by individual commands, such as update-file-user.
For security reasons, passwords specified as an environment variable will not be read by asadmin.
Displays the help text for the command.
The type of report user wants to see.
summary, which displays summary information about the threads/classes and memory.
memory, which provides information about heap and non-heap memory consumption, memory pools, and garbage collection statistics for a given target instance
classes, which gives information about the class loader for a given target instance
threads, which provides information about threads running and the thread dump (stack trace) for a given target instance.
This option specifies the ending location of the connector resources. Valid targets are server, domain, cluster, and instance. The default target is server.
This option is available only in the Sun Java System Application Server Standard and Enterprise Edition.
