Diagcollection.plDiagcollection.pl is a script used to collect the diagnostic information from clusterware installation. The scriptprovides you with additional information so that the Oracle Support can resolve problems.

Invoking diagcollection script

Step 1: Log in as RootStep 2: Set up the following environment variables

# export ORACLE_BASE= /..../# export ORACLE_HOME = /..../# export ORA_CRS_HOME = /.../

Step 3: Run the script

# cd $ORA_CRS_HOME/bin# ./diagcollection.pl -collect

The script generates the following files in the local directory,

basData_.tar.gz (contains logfiles from ORACLE_BASE/admin)crsData_.tar.gz (logs from $ORA_CRS_HOME/log/)ocrData_.tar.gz (results of ocrcheck, ocrdump and ocr backups)oraData_.tar.gz (logs from $ORACLE_HOME/log/)

To collect only subset of log files , you can invoke as follows,

# ./diagcollection.pl -collect -crs (CRS log files)# ./diagcollection.pl -collect -oh (ORACLE_HOME logfiles)# ./diagcollection.pl -collect -ob (ORACLE_BASE logfiles)# ./diagcollection.pl -collect -all (default)

To clean out the files generated from the last run

# ./diagcollection.pl -clean

To extract only the core files found in the generated files and store it in a text file,

# ./diagcollection.pl -coreanalyze

Thanks
