Oracle Clusterware Main Log Files
Oracle Clusterware uses a unified log directory structure to consolidate the Oracle Clusterware component log files. This consolidated structure simplifies diagnostic information collection and assists during data retrieval and problem analysis.
The slide shows you the main directories used by Oracle Clusterware to store its log files:
CRS logs are in <Grid_Home>/log/<hostname>/crsd/. The crsd.log file is archived every 10 MB (crsd.l01, crsd.l02, ...).
CSS logs are in Grid_HOME /log/<hostname>/cssd/. The cssd.log file is archived every 20 MB (cssd.l01, cssd.l02, ...).
EVM logs are in <Grid_Home>/log/<hostname>/evmd.
SRVM (srvctl) and OCR (ocrdump, ocrconfig, ocrcheck) logs are in <Grid_Home>/log/<hostname>/client/ and $ORACLE_HOME/log/<hostname>/client/.
Important Oracle Clusterware alerts can be found in alert<nodename>.log in the <Grid_Home>/log/
<hostname> directory.
