Oracle generates 2 Clsc*.log files every 5 minutes

Environment:

Os:hp-unix

Database: 11.2.0.4 Dual-machine RAC

(i) Phenomenon

While cleaning up the ORACLE logs, it was found that there were a lot of clsc*.log under the $oracle_home/log/{instance_id}/client. After observation, it is found that 2 logs are generated every 5 minutes, as follows:

-rw-r--r--1 Oracle Oinstall 244 Sep 15:55 clsc34691.log-rw-r--r--1 Oracle oinstall 244 Sep 15:55 clsc34692.log- rw-r--r--1 Oracle Oinstall 244 Sep 16:00 clsc34693.log-rw-r--r--1 Oracle oinstall 244 Sep 16:00 clsc34694.log-rw-r --r--1 Oracle Oinstall 244 Sep 16:05 clsc34695.log-rw-r--r--1 Oracle oinstall 244 Sep 16:05 clsc34696.log-rw-r--r- -1 Oracle Oinstall 244 Sep 16:10 clsc34697.log-rw-r--r--1 Oracle oinstall 244 Sep 16:10 clsc34698.log-rw-r--r--1 Oracle Oinstall 244 Sep 16:15 clsc34699.log-rw-r--r--1 Oracle oinstall 244 Sep 16:15 clsc34700.log-rw-r--r--1 Orac Le oinstall 244 Sep 16:20 clsc34701.log-rw-r--r--1 Oracle oinstall 244 Sep 16:25 clsc34702.log-rw-r--r--1 Oracle O Install 244 Sep 16:30 clsc34703.log-rw-r--r--1 Oracle oinstall 244 Sep 16:35 clsc34704.log-rw-r--r--1 Oracle Oinst All 244 Sep 16:40 Clsc34705.log ...

(ii) Reasons

Found this is Oracle in 11.2 bug, in the case of Oracle em on, EM will use crs_stat every 5 minutes to collect the status of Oracle services, resulting in the creation of logs.

(iii) Solutions

Log in as an Oracle user to the directory:

$ORACLE _home/sysman/admin/scripts/

2 Files Modified:

①  Vim crs_resources.pl

" $crs _home/bin/crs_stat "  "$crs _home/bin/crsctl stat res"

②vim crs_vip.pl

" $crs _home/bin/crs_stat "  "$crs _home/bin/crsctl stat res"

Restart EM

Emctl Stop Dbconsoleemctl start dbconsole

CD $ORACLE _home/log/{instance_name}/client
LS-LRT--continuously monitor for half an hour to check if a log file is generated regularly.
