Excerpt

Excerpt

The Start Cleanup (STRCLNUP) command starts the cleanup operation, if allowed. Cleanup is allowed if *YES is specified for the Allow cleanup (ALWCLNUP) parameter of the Change Cleanup (CHGCLNUP) command. A batch job is submitted to the job queue specified on the Change Cleanup (CHGCLNUP) command if cleanup is allowed. This cleanup control job submits individual batch jobs to the same job queue each day These batch jobs do the actual cleanup of the items specified on the CHGCLNUP command. ************ The Change Cleanup (CHGCLNUP) command allows you to specify cleanup options controlling which objects on the system are to be deleted automatically. The cleanup options control the following: whether the cleanup operation is allowed when the cleanup operation is run each day which objects are cleaned up Refer to the following parameter descriptions for a list of the objects that are cleaned up. User messages (USRMSG) System and workstation msgs (SYSMSG) Critical system messages (CRITSYSMSG) Job logs and system output (SYSPRT) System journals and logs (SYSLOG) --- Specifies that system journals, history files, problem log files, and the alert database are cleaned up (deleted). Office calendar items (CALITM) ************** The Submit Job (SBMJOB) command allows a job that is running to submit another job to a job queue to be run later as a batch job. Parameters: Job message queue maximum size (JOBMSGQMX) Specifies the maximum size of the job message queue. Job message queue full action (JOBMSGQFL) Specifies the action that should be taken when the job message queue is full. Message logging (LOG) Specifies the message logging values used to determine the amount and type of information sent to the job log by this job.

Claims

A method for clearing log files of a service system, comprising:configuring a log processing task item for each service of multiple services respectively;

adding a log management task to a task list of an operating system; and

the log management task clearing a log file of each service in turn according to the log processing task item.

Relevance

The Change Cleanup command allows specifying cleanup of SYSLOG, system journals and logs. Cleanup can be scheduled and can selectively clean up log files based on age. Log files on an individual job basis can be controlled by the Submit Job (SBMJOB) command. JOBMSGQMX specifies the log size on a job basis. JOBMSGQFL controls log wrapping. LOG controls what to log and whether a human-readable (spooled job log file) is produced. LOGOUTPUT controls when and if log files are converted to human-readable form.

All

The method as claimed in Claim 1, wherein the log processing task item comprises execution time, log file directory, log file name, log file clearing condition and log file clearing manner.

Relevance

See Claim 1 and the Excerpt.

Claim Chart

All

The method as claimed in Claim 2, wherein the log file clearing manner comprises: deleting a log file, cutting a log file and retaining predefined lines, or deleting an original log file after compressing the log file.

Relevance

See Claim 1 and the Excerpt.

Claim Chart

All

The method as claimed in Claim 2, comprising:the operating system periodically scanning the task list of the operating system and determining a task to be executed currently.

Relevance

See Claim 1 and the Excerpt.

Claim Chart

All

The method as claimed in Claim 5, wherein the step of adding a log management task to a task list of an operating system comprises:configuring the log management task to operate daily.

Relevance

See Claim 1 and the Excerpt.

Claim Chart

All

The method as claimed in Claim 2, wherein the step that the log management task clears a log file of each service in turn according to the log processing task item comprises:the log management task reads one log processing task item, and judges whether it is necessary to clear the log file according to the execution time in the read log processing task item; if yes, then the corresponding log file will be cleared according to the log file clearing condition and the log file clearing manner in the read log processing task item; and

after the log management task has completed the clearing of the current log file, it will read a next log processing task item, and judge whether it is necessary to perform the next task until each log processing task item is read and judged.

Relevance

See Claim 1 and the Excerpt.

Claim Chart

All

A system for clearing log files of a service system, comprising:a configuration module, which is used to configure a log processing task item for each service of multiple services respectively; and

a log management module, which is used to clear a log file of each service in turn according to the log processing task item in the configuration module.

Relevance

See Claim 1 and the Excerpt.

All

The system as claimed in Claim 8, wherein the log processing task item comprises: execution time, log file directory, log file name, log file clearing condition and log file clearing manner.

Relevance

See Claim 1 and the Excerpt.

All

The system as claimed in Claim 9, wherein the log file clearing manner comprises: deleting a log file, cutting a log file and retaining predefined lines, or deleting an original log file after compressing the log file.

Relevance

See Claim 1 and the Excerpt.

Claim Chart

All

The system as claimed in Claim 9, wherein the log management module reads one log processing task item from the configuration module, and judges whether it is necessary to clear the log file according to the execution time in the read log processing task item; if yes, then the corresponding log file will be cleared according to the log file clearing condition and the log file clearing manner in the read log processing task item.

Relevance

See Claim 1 and the Excerpt.

Claim Chart

All

The system as claimed in Claim 12, wherein after the log management module has completed the clearing of the current log file, it will read a next log processing task item from the configuration module and judge whether it is necessary to perform the next task, until each log processing task item in the configuration module is read and judged.
