Normally the REDO log switches take place every 10-15 minutes. That means about 4 to 6 redo log files will be created in one hour. Sometimes it can create 1 tor more redo log files within one minute due to heavy database activity or a large database transaction. This rapid creation of redo log files can fill up the ArchiveLogs directory in less than one hour, and thus cause the eHealth to run out of disk space. This is because most eHealth installations only allocate 10 to 50 Gb for the ArchiveLogs directory.
The instructions below assume redo logs are currently set to 35 Mb and you want to change them to 165 Mb.
