How to roatate .out weblogic logfiles in windows environment

Answer 1

Hello,
You can follow the below approach;
By default, every 24 hours the Windows service archives messages to a file named pathname-yyyy_mm_dd-hh_mm_ss. New messages collect in the file that you specified when you set up the service.
You can change the time interval or you can set up rotation to occur based on the size of the message file instead of a time interval.
To change the default criteria at which the Windows service rotates message files:
If the Windows service is running, shut it down.
Edit the file you specified in the -log: pathname argument. If a file does not exist, create one.
For example, if you issued the example command in step 3. in the previous section, create a file named d:\bea\wlserver6.1\config\mydomain\myserver-stdout.txt.
Do one of the following:
If you want the Windows service to rotate the message file at a specific time interval regardless of file size, add the following statements at the top of the file, each statement on a separate line (make sure to press the Enter or Return key after typing the last line):
# ROTATION_TYPE = TIME
# TIME_START_DATE = date-in-required-format
# TIME_INTERVAL_MINS = number-of-minutes
where TIME_START_DATE specifies when the first rotation should take place. If the specified time has already passed, the first rotation occurs when the time interval specified in TIME_INTERVAL_MINS expires. You must use the following format to specify the start time: Month Day Year Hour:Minutes:Seconds
where Month is the first 3 letters of a Gregorian-calendar month as written in English
Day is the 2-digit day of the Gregorian-calendar month
Year is the 4-digit year of the Gregorian calendar
Hour:Minutes:Seconds expresses time in a 24-hour format
and TIME_INTERVAL_MINS specifies how frequently (in minutes) the Windows service rotates the file.
For example:
# ROTATION_TYPE = TIME
# TIME_START_DATE = Jul 17 2003 05:25:30
# TIME_INTERVAL_MINS = 1440
When the time interval expires, the Windows service saves the file as pathname-yyyy_mm_dd-hh_mm_ss. It then creates a new file named pathname. This new file, which contains all of the headers that you specified originally, collects new standard out and standard error messages.
If you specify # ROTATION_TYPE = TIME but do not include the other lines, the Windows service rotates the message file every 24 hours.
If you want the Windows service to rotate the message file after the file grows beyond a specified size, add the following statements at the top of the file, each statement on its own line (make sure to press the Enter or Return key after typing the last line):
# ROTATION_TYPE = SIZE
# SIZE_KB = file-size-in-kilobytes
# SIZE_TRIGGER_INTERVAL_MINS = polling-interval
where SIZE_KB specifies the minimal file size (in kilobytes) that triggers the Windows service to move messages to a separate file.
and SIZE_TRIGGER_INTERVAL_MINS specifies (in minutes) how frequently the Windows service checks the file size. If you do not include this header, the Windows service checks the file size every 5 minutes.
For example:
# ROTATION_TYPE = SIZE
# SIZE_KB = 1024
# SIZE_TRIGGER_INTERVAL_MINS = 3
When the Windows service checks the file size, if the file is larger than the size you specify, it saves the file as pathname-yyyy_mm_dd-hh_mm_ss. It then creates a new file named pathname. This new file, which contains all of the headers that you specified originally, collects new standard out and standard error messages.
If you specify # ROTATION_TYPE = SIZE but do not include the other lines, the Windows Service checks the size of the message file every 5 minutes. If the file is larger than 1 megabytes, it rotates the file.
