- writing background:
The project is based on the processing mode of java, weblogic and timer. After each service deployment, the overall status of the timer is a blind spot. There should be more than 100 processes. Whether there is a startup omission or repeated startup, it is difficult to understand the time at a glance.
- Program Description:
1) By configuring the system-defined process (timer) into the configuration file process_signal.config
2) Store all the current java processes of the server in process_current.txt
3) Read the processes in process_signal.config line by line and match them in process_current.txt
4) If there is no match, it is a startup omission, and it is stored in process_invalid.txt. If it matches once, it is normal (no processing), and if it matches more than once, the timer name and the number of starts are recorded in process_invalid.txt.
5) Execute the script once every 30 minutes through the timer, use SQLLOAD to load process_invalid.txt into the data table, and monitor the database table.
- Script description:
1. Overall file structure:
webusr@iomtimer1:/weblogic/script/process_signal >ls
process_current.txt process_invalid.txt process_invalid_his.txt process_signal.config process_signal.sh
2. Process configuration example:
webusr@iomtimer1:/weblogic/script/process_signal >cat process_signal.config
#stop recurrenceNAS
extapp.tftonas.PutTfToNas 10 2
extapp.tftonas.PutTfToNas 11 2
extapp.tftonas.PutTfToNas 12 3
3. Execution result record:
webusr@iomtimer1:/weblogic/script/process_signal >cat process_invalid.txt
132.77.255.36 process [extapp.leaseroute.PutToLeaseRoute 180] is not exist 2018-04-11 08:29:00
132.77.255.36 process [ DealWorkTaskTimer 3001 ] is repeatRun 2 Times 2018-04-11 17:51:56
4. Logical matching entry:
