Добрый день.
Подскажите может кто сталкивался с проблемой. В какой то момент времени , сервер перестает бекапить логические журналы и уходит в чек поинт из за их нехватки.
При детальном анализе видно что сервер их правильно заполняет , но вот заархивировать почему то не может и пишет
Команда ontape -a выдает следующее
1.

[root@onldb2 /]# ontape -a
Performing automatic backup of logical logs.
Please mount tape 1 on /usr/informix_log/log.bkp and press Return to continue ...
This tape contains no log data
При этом скрипт аларм шела начинает их писать но доходя до 32 к перестает, с выше названной ошибкой.
Сервер на котором это все происходит
IBM Informix Dynamic Server Version 11.10.UC1 -- On-Line -- Up 03:09:25 -- 480744 Kbytes

08 : 21 : 16 Logical Log 17532 Complete, timestamp: 0xa69ae82a.
08 : 21 : 18 Logical Log 17532 - Backup Started
08 : 21 : 18 Adjusting LRU for bufferpool - id 0 size 2k

08 : 21 : 19 Logical Log 17532 - Backup Completed
08 : 21 : 19 Performance Advisory: Logical log file size might be too small for a
checkpoint to complete.
08 : 21 : 19 Results: The size of individual logical log files is too small for
the current workload, resulting in each log file filling very
quickly. If log files fill in less than 30 seconds, the checkpoint
might remain blocked because the last log file fills during the time
needed to perform the checkpoint.
08 : 21 : 19 Action: Increase the size of the individual logical log files so
that it takes at least 30 seconds to fill each one. Look at the
online log to determine how quickly the log files are filling, and
then increase the size of the files proportionately.
