init.wbem - start and stop the CIM Boot Manager SYNOPSIS
/etc/init.d/init.wbem start | stop | status DESCRIPTION
The init.wbem utility is run automatically during installation and each time the system is rebooted. This utility manipulates the CIM Object Manager (CIMOM) and the Solaris Management Console server, both of which run combined in a single process. init.wbem can be used to start, stop, or retrieve status from the server. CIM Object Manager The CIM Object Manager manages CIM objects on a WBEM-enabled system. A CIM object is a computer representation, or model, of a managed resource, such as a printer, disk drive, or CPU. CIM objects are stored internally as Java classes. When a WBEM client application accesses information about a CIM object, the CIM Object Manager contacts either the appropriate provider for that object or the CIM Object Manager Repository. Providers are classes that communicate with managed objects to access data. When a WBEM client application requests data from a managed resource that is not available from the CIM Object Manager Repository, the CIM Object Manager forwards the request to the provider for that managed resource. The provider dynamically retrieves the information. At startup, the CIM Object Manager performs the following functions: o Listens for RMI connections on RMI port 5987 and for XML/HTTP connections on HTTP port 5988. o Sets up a connection to the CIM Object Manager Repository. o Waits for incoming requests. During normal operations, the CIM Object Manager performs the following functions: o Performs security checks to authenticate user login and authorization to access namespaces. o Performs syntactical and semantic checking of CIM data operations to ensure that they comply with the latest CIM Specification. o Routes requests to the appropriate provider or to the CIM Object Manager Repository. o Delivers data from providers and from the CIM Object Manager Repository to WBEM client applications. A WBEM client application contacts the CIM Object Manager to establish a connection when it needs to perform WBEM operations, such as cre- ating a CIM class or updating a CIM instance. When a WBEM client application connects to a CIM Object Manager, it gets a reference to the CIM Object Manager, which it then uses to request services and operations. Solaris Management Console Server The Solaris Management Console server is the back end to the front end console, smc(1M). It provides tools for the console to download and performs common services for the console and its tools to use, such as authentication, authorization, logging, messaging, and persistence. System Booting The init.wbem script is installed in the /etc/init.d directory. OPTIONS
The following options are supported: start Starts the CIMOM and Solaris Management Console server on the local host. stop Stops the CIMOM and Solaris Management Console server on the local host. status Gets the status of the CIMOM and Solaris Management Console server on the local host. NOTES
When the init.wbem script is run, it does not run the CIMOM and Solaris Management Console server directly. The server process is in Java and is too heavyweight to be run immediately at system boot time. Instead, three lightweight processes listen on three different ports that the CIMOM and the Solaris Management Console server normally use. This acts similarly to inetd(1M). Because Java programs cannot inherit file descriptors as other programs can, there is a small time period from when the first connection is made until the server is fully operational where client connections may be dropped. WBEM clients are immune to this, as they will retry until the server comes online. Solaris Management Console clients are not immune, and it may be necessary to manually reconnect, though this should not happen in the common case. ATTRIBUTES
