ocssd.log filesize >50M

在做資料庫維護時,突然發現 ocssd.lo1 歸檔log 大小超過5G，這絕對不正常。

使用 crsctl get css logfilesize 命令來看設定的css log size 是多少。 

[oraprod@**** ~]$  crsctl get css logfilesize
CRS-4676: Successful get logfilesize 52428800 for Cluster Synchronization Services.

發現是預設值50m 沒有做任何修改。

在support.oracle.com 中查詢原因，發現 “It is caused by unpublished Bug 18700935 - CLOUD:ACLDX0085 OCSSD LOG IS NOT ROTATED"

解決方案也很清楚：

SOLUTION

The CSSD thread that encountered the LFI-00142 error needs to be restarted to ensure log rotation works again.

Manually deleting the logfile will not resolve the log rotation problem.

1).  Shutdown CRS on the node reporting the problem.

# crsctl stop crs

2).  Once CRS is down,  proceed to manually delete the 'ocssd.l10' file, or copy the logfile to another location if you need to keep a backup.

# rm  $GRID_HOME/log/<hostname>/cssd/ocssd.l10

3).  Startup Clusterware again

# crsctl start crs

 

If you are NOT able to schedule downtime and file size growth in the GRID Home is causing a space issue then copy the logs to another location and do the following

% echo 0 > ocssd.l10

  
Please note this does not resolve the log rotation problem but only allows you to free up some space.

4). Bug 18700935 has been fixed in 11.2.0.4.5 PSU for Unix/Linux platform and 11.2.0.4.12 Bundle for Windows platform. Please apply the patch if required.
