Помогите с настройкой. Установили PostgreSQL 8.2 что идёт с 1с на ALT Linux office server. Несколько дней было счастье всё работало быстро. Но потихоньку скорость начала падать. И теперь всё это дело здорово тормозит. Что можно покопать. Всякие перезагрузки и всё прочее результата не дало никакого. Вакум этот и всё прочее. Что теперь делать ума не приложу.
Что
Что происходило с сервером в течении этих нескольких дней ? На сколько увеличился объем данных ?
Как настроен vacuum ? рекомедую запускать через cron, туда же можно добавить reindex.
Настройки PostgreSQL по-умолчанию ?
Что еще работает на сервере ?
В принципе уже
В принципе уже сказали. Судя по описываемым тобой симптомом не делается vacuum.
Необходимо настроить регулярный вызов VACUUM ANALYZE по крону хотя бы раз в сутки, а если данные часто меняются (добавляются, удаляются, вставляются в больших объёмах) то выполнять это несколько раз в сутки.
Ещё можно попробовать перейти на версию 8.3, там вроде бы как обещали AUTOVACUUM.
Вакум работает
Вакум работает пробовал из пжадмина запускал автовакум. Пишет что удаляет что то. Короче толку ни какакого. А анализ этот делал. База ну саму посудите насколько могла увеличиться база которая ведётся два года за полторы недели. В том же самом темпе. Документов не стало больше. Мой конф.

#
# This file consists of lines of the form:

#
# (The '=' is optional.) White space may be used. Comments are introduced
# with '#' anywhere on a line. The complete list of option names and
# allowed values can be found in the PostgreSQL documentation. The
# commented-out settings shown in this file represent the default values.
#
# Please note that re-commenting a setting is NOT sufficient to revert it
# to the default value, unless you restart the server.
#
# Any option can also be given as a command line switch to the server,
# e.g., 'postgres -c log_connections=on'. Some options can be changed at
# run-time with the 'SET' SQL command.

Ну тогда всё
Ну тогда всё что могу предложить - это включить логгирование по максимуму и смотреть логи - что вообще происходит.
На особо долгих запросах можно прогнать explain и также посмотреть цепляются ли индексы и т.д.
Установка postgres для 1С
Скажите пожалуйста как правильно поставить Postgres на Red Hat Enterprise Linux 5для 1С? Устанавливал 8.2.5 не 1С. Устанавливал все пакеты двойным нажатием на пакет. Потом пропатчил патчами 1С к версии 8.2.4 скачанными из http://v8.1c.ru/overview/postgres_patches_notes.htm. Но появляется ошибка:
ERROR: could not access "$libdir/mchar": No such file or directory;
Error while executing the query
Error [CreateDataBase]: Can not create database.
postgresql-contrib я устанавливал.
Файл "postgresql-8.2.4-6.1C.src.rpm" взятый с сайта 1С не устанавливается у меня. И вообще зачем нужен и как его устанавливать?
Попробовал скачать с ftp://ftp.etersoft.ru/pub/Etersoft/PostgreSQL/8.2/RHEL/5 постгрес. Как я понял он уже пропатчен для 1С. Но при /etc/init.d/postgresql start выдает вот такое сообщение:
"Starting postgresql service: /etc/init.d/postgresql: line 228: pidof: command not found" И в скобках написано [FAILED].
Как я понимаю postgres не запускается. Но почему что я не так делаю?
Могу только по
Могу только по последнему случаю/ дать коммент.
Посмотрите наличие в системе команды pidof.
В CentOS5, который собирается на основе RHEL, эта команда находится в пакете SysVinit-2.86-14. Если у вас он не стоит - поставьте.
Если стоит, то возможно в скрипе запуска /etc/init.d/postgresql указан неправильный путь к pidof - проверьте.

SysVinit-2.86-14 у меня
SysVinit-2.86-14 у меня установлен а есть в ней pidof или нет это я уже не знаю. Как это посмотреть?
А как посмотреть в /etc/init.d/postgresql путь к pidof? Там про это всего пару строчек вот:
sleep 2
pid=`pidof -s "$PGENGINE/postmaster"`
if [ $pid ] && [ -f "$PGDATA/postmaster.pid" ]
then
success "$PSQL_START"
#hack for *deb
И еще какой то текст но там путь не указывается.
Посмотреть
Посмотреть путь можно так:
# which pidof
У меня он в /sbin
В /etc/init,d/postgresql попробуйте заменить
pid=`pidof -s "$PGENGINE/postmaster"`
на
pid=`/sbin/pidof -s "$PGENGINE/postmaster"`
-----------------------------------------------------------------------------------

У меня тоже pidof
У меня тоже pidof находится в папке sbin. Но когда я изменил файл postgresql и попробовал его сохранить то в верху появилась вот такая надпись:
Не удалось сохранить файл "/etc/init.d/postgresql".
Недостаточно прав для сохранения файла. Убедитесь, что адрес введен правильно, и попробуйте еще раз.
Запускал which pidof написало вот так:
[root@bio bio]# which pidof
/usr/bin/which: no pidof in (/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/bio/bin)
В linux я новичок не знаю как сохранить файл postgresql?
Опа! А ты не из
Опа! А ты не из под root'а что ли работаешь?
Если да, то понятно в чём дело - службы запускать только root может
-----------------------------------------------------------------------------------
"ls /" (C) Козьма Прутков
Из под root'а. Я
Из под root'а. Я прежде чем запускать службы набираю su root. А вот почему недостаточно прав чтоб изменить и сохранить файл postgresql?
Тогда начни всё
Тогда начни всё таки не с
su root
а с
su - root
глядишь всё и запустится
-----------------------------------------------------------------------------------
"ls /" (C) Козьма Прутков
Я заходил
Я заходил просто не из под root'а! Теперь зашел из под него и изменить получилось. Зашел в смысле при загрузки RHLE 5. Но это не помогло. Теперь просто пишет [FAILED]. Можно еще что то сделать?
Хочу теперь попробовал поставить обычный postgres 8.2.6 и пропатчить его. Но не магу удалить старый postgres lib! Из "Установки и удаления программ" это не получается и все! Другие пакеты posgres удалились а этот не хочет!?
Если пишет FAILED -
Если пишет FAILED - читай лог, в нём должно быть написано - почему.
