摘要： A number of methods, apparatus, and data structures are disclosed for managing computer processes. In one aspect, a daemon process which manages server processes includes an active server table and a locator service. The locator service can look up and register server processes in the active server table. Furthermore, the locator service can start up server processes. In some embodiments, the locator service includes a look-up object and a server process registration object which perform the tasks of the locator service. In other embodiments, methods for managing server process such as starting and registering the server processes are taught. In one specific method, a daemon process performs a variety of steps in response to receiving a look-up call for a target object. These steps include obtaining a server identifier for the target object, determining the state of a server process, and returning addressing information corresponding to the server process under which the target object will activate. In related method aspects the daemon process will start the server process if it isn't running and/or wait until the server process is running to return the addressing information. In a separate method aspect, a server process self-starts; receiving an object reference for a desired target object, receiving a server process identification number, creating a communications port for itself, forming addressing information for itself, obtaining an object reference for a server process registration object, and registering itself by calling the server process registration object to invoke a register new process operation.

摘要： A method of checking the type of an object located on a remote computer in a distributed object environment computing system is disclosed. Initially, a type checking method to determine whether a remotely located object is of a specified type is invoked. In the invocation, a target interface identifier is included as an argument. A determination is then made as to whether the target interface identifier is equal to or a base for an apparent interface identifier held by a proxy object located on the first computer. If the target interface identifier is determined to be equal to or a base for the apparent interface identifier, an affirmative indication to that effect is returned to the client process. If not, then the target interface identifier is then compared to a real interface identifier. In many embodiments, a call to the server host will have to be made in order to determine the real interface identifier. In some embodiments, a local cache memory can also be provided to store the results of such inquiries. The target interface identifier is then compared to the real interface identifier and a determination is made as to whether the target interface identifier is equal to or a base for the real interface identifier. The result is then returned to the client process. A method of checking the type of an object and additionally returning an output proxy object is also disclosed. The output proxy object may be the original input proxy object that has been widened to the class associated with the target interface identifier, or may be a newly created proxy object that is of the same kind as the input proxy and of the same type as the target interface identifier.

摘要： A method and apparatus for managing connections between objects in a distributed object system includes a method and apparatus for terminating connections between objects. In one aspect, the method for terminating a connection, a connection end message is sent from a server to a client indicating to the client that the server will no longer accept requests before the connection is terminated. Preferably a connection end code is included with the connection end message. In another aspect, the invention includes a method for making connections between objects are formed by intelligently closing existing connections that meet the criteria of being established and across which no unfulfilled requests or unforwarded replies are pending. If several connections meet these criteria, the oldest unused connection is terminated. The methods and apparatus described provide for the creation and termination of connections efficiently and robustly by allowing the controlled shut down of connections between clients and servers without invoking an error state.

摘要： Data structures, methods, and devices for facilitating servant invocation in a distributed client-server based object oriented operating system are disclosed. In one aspect of the invention, descriptor data structures, which contain a typecode indicator, a marshaling function identifier, and an unmarshaling function identifier, are used to enable modules of application code to be shared between different objects, thereby facilitating servant invocation by increasing the amount of commonized code in the operating system. In another aspect of the invention, a server invocation object is used in the execution of a method call. In still another aspect of the invention, a commonized code base is used to process typecode interpreted and compiled calls to a server process.

摘要： A variety of methods and apparatus for managing deactivation and deletion of objects and server processes are taught. According to some embodiments of the present invention, a thread of execution termed the reaper thread systematically cycles through a computer process deactivating and/or deleting objects based upon a variety of criteria. One suitable criterion for object deactivation is based upon the amount of time lapsed since a client has requested services of the object. According to the timeout criterion, the reaper thread determines the period of time since the last client requested services from the object, compares this to a timeout value which may be defined by any suitable entity, and proceeds with deactivation and/or deletion accordingly. Object deletion may have a separate criterion or be specifically requested by a client. A deletion flag may be set to indicate that object deletion is requested. When an object has deactivated, the reaper thread further determines if the deletion flag for this object is set, and, if so, further proceeds to perform an object deletion operation. In some embodiments, the reaper thread is further responsible to shutdown the server process under which the reaper thread is executing. As is well known to those skilled in the art of object oriented programming, a thread of execution is essentially a sequential flow of the point of execution through a computer process. One suitable criterion for server process shutdown would be related to the server process activity.

摘要翻译： 教导了用于管理对象和服务器进程的去激活和删除的各种方法和装置。 根据本发明的一些实施例，称为收割器线程的执行线程系统地循环通过计算机进程基于各种标准去激活和/或删除对象。 对象停用的一个合适的标准是基于客户端已经请求了该对象的服务所经过的时间量。 根据超时标准，收费线程确定自上次客户端从对象请求服务之后的时间段，将其与可由任何合适实体定义的超时值进行比较，并相应地执行去激活和/或删除。 对象删除可能有一个单独的标准或客户端特别要求。 可以设置删除标志以指示请求对象删除。 当对象已被停用时，收割者线程还确定是否设置了该对象的删除标志，如果是，则进一步进行对象删除操作。 在一些实施例中，收割机线程还负责关闭在其下执行收割机线程的服务器进程。 如面向对象编程领域的技术人员所熟知的，执行线程本质上是通过计算机进程的执行点的顺序流程。 服务器进程关闭的一个合适标准将与服务器进程活动相关。

摘要： Disclosed are various embodiments for providing limited versions of applications. A limited version of an application is automatically generated from a full version of the application based at least in part on an expected use of the application by a client computing device during a testing period. The limited version has a smaller data size than the full version. The limited version of the application is sent to the client computing device. The limited version of the application is configured to be executed in a secured environment of the client computing device. The secured environment denies the limited version of the application access to secured resources of the client computing device.
