Problem:
There is an unpublished Bug 29845449 in Oracle 19c, causing the following message to be written frequently in the DB alertlog:
2022-10-12T13:42:54.212579+00:00
XDB initialized.
2022-10-12T13:43:48.993302+00:00
XDB initialized.
Solution: [Works on Linux OS only]
You can run the following command to clean up "XDB initialized"message from the alertlog and two lines above it, which include the timestamp as well:
[Replace /u01/oracle/diag/rdbms/orcl/orcl/trace/alert_orcl.logwith your right database alertlog path]
# vim -e - /u01/oracle/diag/rdbms/orcl/orcl/trace/alert_orcl.log<< EOF
g/XDB initialized/.-2,.d
wq
EOF
Excerpt from the alertlog file before running the command:
After running the command:
Looks cool!
I'll add this feature shortly to the dbalarm script to automatically get rid of this message whenever the script runs:
