Thread 1 cannot allocate new log, sequence 639472, Checkpoint not complete

edited Apr 7, 2022 2:35PM in Database Administration (MOSC) 2 commentsAnswered

Today database got down. Listener control was stopped and database was not mounted. I have restarted the listener and database, now application is running well but I have found some problem in the log file related to checkpoint and afraid, it could go down anytime. Please find the attached log file and below is just a glimpse.
