This issue may occur after an OS crash, reboot or services restart.

In order to check if you are seeing this problem perform the following steps.

1. Go to $LOG_HOME/ora/10.1.3/opmn/ and check the process ID of oacore that is writing to the file default_group~oacore~default_group~1.log by executing the following command:

/usr/sbin/fuser default_group~oacore~default_group~1.log


2. Execute 3 times at 30 seconds interval

kill -3 <oacore process ID>


3. Check again the file default_group~oacore~default_group~1.log which should show the following stack trace:

If file $COMMON_TOP/cacheLock file exists before oacore service is started, the above thread will be locked and the oacore service will hang until timed out.

解决方法:

Remove $COMMON_TOP/cacheLock file which is a 0 bytes file created at startup time

1. cd $COMMON_TOP
2. rm cacheLock
3. Start oacore using

$ADMIN_SCRIPTS_TOP/adoacorectl.sh start
