[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, a first embodiment of the present invention provides a process management method based on an embedded operating system. The embedded operating system is, for example, a Linux system. Alternatively, the method may be executed by a processor, as shown in fig. 1, and the process management method includes, for example, steps S11 to S14.
Step S11: creating a local socket to establish communication connection with a plurality of target processes, wherein the target processes are processes for binding the local socket when being started;
step S12: receiving process registration information respectively transmitted by the target processes which have established the communication connection;
step S13: establishing a process management list according to the process registration information;
step S14: and broadcasting and sending the process management list to the plurality of target processes so that each target process establishes a communication relation with other target processes according to the process management list.
The local socket mentioned in step S11, such as UNIX socket, is mainly used in inter-process communication (IPC). The operation mechanism of UNIX sockets is similar to that of Internet sockets, with the main difference that UNIX sockets can only be used on one computer, while Internet sockets can be used between different computers. The UNIX socket addresses as a file in the local file system. Further, step S11 includes, for example: and creating the local socket, and selecting the target processes from the processes according to self configuration information to establish communication connection. The self-configuration information mentioned therein includes, for example, the name of the process that needs to establish the communication connection. Target processes are selected from the multiple processes through self configuration information, so that communication is limited among the associated processes, and safety is improved.
The process registration information mentioned in step S12 includes, for example: the process identifier represents a process-defined ID number in order to represent a unique process. The process name mentioned represents a process alias, and corresponds to an ID number, so that the process alias is convenient to identify. The process states mentioned include an online state, an offline state, and an undefined state.
The process management list mentioned in step S13 is a table including process registration information corresponding to a plurality of target processes, and the content in the table includes information such as a process identification code, a process name, and a process state.
The step S14 of establishing, by each target process, a communication relationship with other target processes according to the process management list includes, for example: and each target process analyzes the process management list to obtain the process states corresponding to the other target processes, and establishes communication connection with the other target processes in response to the process states of the other target processes being in an online state. The communication relationship mentioned above may be understood that, after each target process parses the process management list to obtain other target processes in the online state, the target processes are all in communication connection with the other target processes, and the target processes are not in communication connection with the other target processes in the offline state. Therefore, the process information of each target process can be informed to other target processes in a process communication mode, and the communication among the online target processes is realized.
Further, the step S14 of establishing, by each target process, a communication relationship with other target processes according to the process management list includes, for example: each target process analyzes the process management list to obtain the process states corresponding to the other target processes, and determines a connectable process from the other target processes according to self configuration information; and responding to the process state of the connectable process as an online state, and establishing communication connection with the connectable process. The mentioned self-configuration information includes, for example, a process name of the connectable process. The mentioned communication relationship may be understood that, after each target process analyzes the process management list to obtain other target processes in the online state, the target processes may be screened according to their own configuration information, and only establish communication connection with the connectable processes in the online state, but not establish communication connection with other target processes including other target processes in the offline state and/or other target processes in the online state. Therefore, the connectable processes are selected from other target processes through the self configuration information, so that the communication is limited among the associated processes, and the safety is improved.
Further, as shown in fig. 2, the process management method according to the first embodiment of the present invention further includes, for example, step S15 and step S16 after step S14.
Step S15: and sending a heartbeat packet to each target process, and updating the process state of the target process in the process management list to be an offline state in response to the target process not replying a response packet within a preset number of times.
Step S16: and broadcasting the off-line state of the target process to the target processes so as to disconnect the communication by the target process which establishes the communication connection with the off-line target process.
Specifically, the heartbeat packet mentioned in step S15 is a self-defined command word for periodically detecting the process state of the target process, and is a data packet sent at a certain time interval. The preset number of times referred to is the number of times of non-response of the custom setting, for example, 3 times. The process state of the target process is detected by sending the heartbeat packet, and the process state of the offline target process is changed into the offline state in the process management list, so that the process state can be conveniently inquired in real time.
The step S16 is to send the offline status broadcast of the target process to the target processes, for example, to broadcast all the relevant process registration information of the offline target process, including the process identification code, the process name, and the process status. The offline state is broadcasted to the target process, so that the target process which establishes communication with the offline target process disconnects the communication, and the communication controllability of each process is realized.
Further, the process management method according to the first embodiment of the present invention further includes, for example: and responding to the information viewing instruction, and displaying the process running state information corresponding to the target processes. The process running state information includes, for example, information such as a process name, a process identification code, a process state, a process PID, and a preset number of times, where content included in the process running state information is displayed according to header content of a display table set by a user. The information viewing instruction mentioned is, for example, an information viewing instruction generated in response to a command input operation by a user, for example, executing "telappnet tmd tcb". Although the process running state information can also be read in the prior art, the read process running state information is running state information of all processes in the system, and therefore a lot of read process information is not needed.
For a better understanding of the present embodiment, a brief description of a specific implementation of the present embodiment is provided below in conjunction with fig. 3.
As shown in fig. 3, in the present embodiment, a process management tool related to implementing the process management method provided in this embodiment is, for example, a TMD process, and target processes are, for example, a process a, a process B, and a process C, although the number of the target processes is not limited in the present invention. The method specifically comprises the following steps:
first, the TMD process is launched and a local socket is created. Wherein the TMD process needs to be started first as a process management tool. The process a, the process B and the process C can be randomly started after the TMD process is started, and the starting sequence of the process a, the process B and the process C is not limited.
Each process would then create its own local socket binding file at startup. Because the TMD process is started firstly, the process A, the process B and the process C can automatically bind the local socket of the TMD process after the local socket is created during starting so as to realize the communication connection between the TMD process and the process A, the process B and the process C.
Then, after the process a, the process B and the process C establish communication with the TMD process, the process a, the process B and the process C notify the TMD process of their own states, that is, the process a, the process B and the process C may send their own process registration information to the TMD process. The process registration information includes, for example, a process name, a process identification code and a process state, when communication is initially established, the process a, the process B and the process C are all in an online state, a process management list is created after the process registration information of the process a, the process B and the process C is received by the TMD process, the process name, the identification code and the process state are listed in the process management list, the TMD process broadcasts the online state of each process, and the TMD process broadcasts the process management list to inform the process a, the process B and the process C.
At this time, process a, process B, and process C may establish communication connection with each other after receiving the process management list, for example, monitor each other and receive and transmit data.
Then, the TMD process sends heartbeat packets to process a, process B, and process C, respectively, in a broadcast manner, waiting for a response. At this time, if the response packet of a process is not received for three times, the process state of the process is set to be the offline state in the process management list and the offline state is broadcasted, and other processes disconnect the communication connection with the process after receiving the TMD process broadcast message. For example, if the TMD process sends a heartbeat packet to the process a in a broadcast manner and does not receive a response packet for three consecutive times, the TMD process changes the process state of the process a from the online state to the offline state in the process management list, then broadcasts the related information of the process a, and after the process B and the process C receive the broadcast information and find that the process a is offline, disconnects the session previously established with the process a.
In addition, the TMD process keeps the session with the process a, the process B and the process C and records the running state of the process at any time. In order to check the running state of each process in the current system, an interface is opened for state printing. Namely, the process running state information corresponding to each process can be obtained by executing the telapnet TMD tcb in the TMD process. For example, the process running state information includes: carrying out identification code, namely process self-defined ID number; the process name is an alias of the process, and the name corresponds to the ID number, so that the process name is convenient to identify; process state, i.e. running state of the process, online: online, offline: offline, unf: is undefined; process PID; and the maximum times that the response packet is not received after the TMD process sends the heartbeat packet.
In addition, the TMD process, the process a, the process B, and the process C all have self-configuration information, and the self-configuration information of the TMD process includes a process name of the monitoring broadcast. The self configuration information of the process a, the process B, and the process C includes connectable process names. The TMD process determines the process to be managed according to the self-configuration information, and the self-configuration information can be modified according to the user requirements, so that the interference of irrelevant processes is eliminated, and the process management efficiency is improved. The TMD process, the process A, the process B and the process C establish communication connection with other processes through self configuration information, so that communication is limited among the associated processes, and the safety is high. In addition, when some processes depend on other processes and can be started only after other processes are started, the running state of other processes can be judged through the TMD process.
In summary, the process management method provided in the first embodiment of the present invention establishes communication with a target process by creating a local socket, receives a process registration information establishment list of the target process, and then broadcasts and sends the process registration information establishment list to a plurality of target processes, so that each target process establishes a communication relationship with other target processes according to the process management list, and can inform the process information of each target process to other target processes in a process communication manner, thereby implementing management of the plurality of processes, and the processes can communicate directly after establishing connection without subsequent authentication, thereby improving communication efficiency between the processes; the process state of the process is inquired in real time by sending the heartbeat packet to the target process and changing the process state of the target process which does not reply the response packet within the preset times into an offline state; the off-line state of the target process is sent to the target processes, so that the other target processes disconnect the communication with the off-line target process, and the controllability of the communication of each process is realized; the association relation of each process can be set through the self configuration information, so that communication is limited between the associated processes, the safety is higher, and the interference of irrelevant processes can be eliminated.
