Full Discussion: Not able to delete log file
Operating Systems Solaris Not able to delete log file Post 302865155 by solaris_1977 on Thursday 17th of October 2013 07:58:37 PM

Not able to delete log file
On my solaris-10 box, there are two log files which are being used (written by) some application. Those are hige files of 3 gb and 5 gb. I tried to nullify it, but it shows me zero size and after few seconds it will show me its original size. "ls -ltr" shows me big size, but "du -sh file" shows me in kb. We do not want to stop application to clear these files. Is there any way to clear them without stopping application. Below outputs should say my problem more clearly.
Code:

TOMOYO-AUDITD(8)					  System Administration Utilities					  TOMOYO-AUDITD(8)

NAME

       tomoyo-auditd - access request log recording daemon for TOMOYO Linux

SYNOPSIS

       tomoyo-auditd

       tomoyo-auditd [remote_ip:remote_port]

DESCRIPTION

       This program reads access request logs from the kernel and writes to the locations specified in the configuration file. By running this
       program at startup, access request logs for either all domains or selected domains can be stored.

       The format of the stored logs is similar to domain policy, so they can be used to help develop policy.

       Configure this daemon in /etc/tomoyo/tools/auditd.conf. If an access request matches a rule, it will be written to the specified log file.
       This can be used to split access request logs into multiple files. Only the first matching rule is used, so any single access request log
       will be written to a maximum of one output file. If an access request log does not match any rules, it will be discarded.

       Start this program from an appropriate stage during startup (e.g. /etc/rc.local).

OPTIONS

       remote_ip:remote_port
	   Retrieve access request logs from a remote system via an agent, connecting to the specified IP address and port number.

       If you find any bugs, send an email to <tomoyo-users-en@lists.sourceforge.jp>.
