Fig. 3 is a flowchart of another method for managing long connection according to an embodiment of the present invention, as shown in fig. 3, where the method includes:
step 201, a process state table is obtained.
In the embodiment of the invention, each step is executed by the control unit.
In the embodiment of the invention, the process state table can be acquired from the memory; alternatively, the process state table is obtained from a database.
In the embodiment of the invention, the process state table comprises a plurality of long connection processes and the running state information of each long connection process, wherein the running state information comprises, but is not limited to, a transaction name, a time stamp of last normal communication, a switch state, a connection running state and a process number. The switch state can be set in the configuration center, and is imported into the memory by the application system, and the switch state is obtained from the memory, so that the access of the switch can be increased without affecting the transaction performance, and the requirement of dynamic refreshing is met.
In the embodiment of the invention, if the process state table is stored in the database, the switch is accessed by setting the transaction to reach a certain processing number, and in order to reduce the access times to the switch, the processing number can be set to be 1 to 20 so as to reduce the access frequency of the switch and improve the transaction processing efficiency.
Step 202, detecting abnormality of the connection state of the current long connection process according to the switch state and the connection running state, and if the connection is abnormal, executing step 210; if the connection is normal, step 203 is performed.
In the embodiment of the invention, the switch state comprises a closed state, an open state and a to-be-restarted state, and the connection operation state comprises an enabled state and a non-enabled state. The switch state may be modified when the connection process is started and closed. When the switch state is the off state, the corresponding normal connection running state is a non-start state; when the switch state is the on state, the corresponding connection running state under normal conditions should be the starting state; when the switch state is to be restarted, the current long connection process is restarted, and the connection running state after restarting is the starting state.
Specifically, the connection running state is detected through the switching state of the current long connection process, so as to judge whether the connection state of the current long connection process is abnormal or not. Specifically, if the switch state includes on and the connection running state is the enabling state, determining that the connection state of the current long connection process is normal connection, and continuing to execute step 203; if the switch state includes the off state and the connection running state is the non-enabling state, determining that the connection state of the current long connection process is normal connection, and continuing to execute step 203; if the switch state includes closing and the connection running state is the enabling state, determining that the connection state of the current long connection process is abnormal connection, and continuing to execute step 210; if the switch state includes on and the connection running state is not enabled, it is determined that the connection state of the current long connection process is abnormal connection, and step 210 is continued.
Step 203, according to the process number and the preset query instruction, performing anomaly detection on the connection state of the current long connection process, and if the connection is abnormal, executing step 210; if the connection is normal, step 204 is performed.
In the embodiment of the invention, each long connection process corresponds to a unique process number, the query instruction is preset, and the execution of the query instruction can query whether the corresponding long connection process exists or not through the process number. Specifically, executing the query instruction according to the process number to obtain a query result, if the query result includes that the current long connection process exists, determining that the connection state of the current long connection process is normal, and continuing to execute step 204; if the query result includes that the current long connection process does not exist, it is determined that the connection state of the current long connection process is abnormal, which indicates that the long connection process is down when it is abnormal, and step 210 is continuously executed.
Step 204, adding lock resources to the current long connection process.
In the embodiment of the invention, the on-off state, the connection running state and the existence state of the current long connection process are all normal, which indicates that the current long connection process is not suspended, and the long connection process needs to be further detected by a detection message. Before sending the detection message, lock resources are needed to be added to the current long connection process, so that other business transactions are prevented from using the current long connection process.
Step 205, detecting an abnormality of the connection state of the current long connection process through a preset detection message, and if the connection is abnormal, executing step 210; if the connection is normal, step 206 is performed.
Specifically, the detection message is sent to a platform server through the current long connection process and a client communication unit; receiving a feedback message sent by a platform server through a client communication unit in the set receiving time; comparing the received feedback message with the stored feedback message, if the received feedback message is the same as the stored feedback message, determining that the connection state of the current long connection process is normal, and continuing to execute step 206; if the sending of the detection message fails or the feedback message sent by the platform server through the client communication unit is not received within the set receiving time, the connection state of the current long connection process is determined to be abnormal, and the step 210 is continuously executed. The receiving time may be set according to practical situations, which is not limited in the embodiment of the present invention.
