2. 问题确认
This is a known bug:
Bug 6899547 – DIAGCOLLECTION.PL FAILS WITH MANDATORY ARGUMENT ‘CRSHOME’ IS MISSING
3. 解决方案
Workaround:
The workaround is simply to add the crs home to the command as follows:
#export ORACLE_HOME=/u01/oracle/app/oracle/product/10.2.0/db #export ORA_CRS_HOME=/u01/oracle/app/oracle/product/10.2.0/crs #./diagcollection.pl --collect --all --crshome $ORA_CRS_HOME
This bug affects 10.2.0.4 and 11.1.0.6 releases for all platforms. This bug has been fixed in 11.1.0.7.
