Could you be so kind to share your experience with mentioned patch set 9.2.0.5 and other patches required for successful AIO implementation on RHEL AS 3 regarding release 9.2.0.4 performance improvement.
А у меня не работает инсталлятор, по-моему из-за x.org (xhost & export DISPLAY сделаны):
Exception in thread «main» java.lang.InternalError: Can’t connect to X11 window server using ‘127.0.0.1:0.0’ as the value of the DISPLAY variable. at sun.awt.X11GraphicsEnvironment.initDisplay(Native Method) at sun.awt.X11GraphicsEnvironment.

а у меня запскается инсталятор, но не реагирует ни на какие кнопки окромя «О инсталяторе» и «удаление установленных продуктов» и не догнать из-за чего.

Открой командную строку заново. Така ошибка бывалевается вроде когда ты уже использовал su. У меня так было.
Так как же избавиться от ошибки, у меня точно такая же выползает Exception in thread «main» java.lang.InternalError: Can’t connect to X11 window server using ‘127.0.0.1:0.0’ as the value of the DISPLAY variable. at sun.awt.X11GraphicsEnvironment.initDisplay(Native Method) at sun.awt.X11GraphicsEnvironment.

Не освещен вопрос с glibc есть там такая кочевряжина запускаещь ./runInstaller а он (подумав немного) выдает что то вроде libc++blablabla.so.2 not found (точно не помню).
теперь заменен на /tmp/libaio-oracle-0.3.0/libaio-oracle.o
вбил все в скрипты, и без единой проблемы все пошло. Всего то там танцев — правка двух файлов (пришлось скриптик накатать), установка десятка RPM (в том числе пары насильно), и точное следование инструкциям. При том я абсолютно не спец по ораклу.
А вот рядом индус уже второй день мучается, с творческим подходом — типа -opatch нужен а он не работает потому что были эксперименты с установкой oracle10, ну и так далее. В общем, чем меньше творчества, тем лучше.
Кстати, Firewire пригодно для development, работает (хотя и виснет при сильной нагрузке).
В общем, очень рекомендую ту статью. Хотя для установки на _не ES_ там, наверное, придется еще что то ручками делать.

Chapter 17. Database Servers
This chapter guides you through the installation and configuration of the MariaDB server, which is an open source fast and robust database server that is based on MySQL technology. The chapter also describes how to back up MariaDB data.
17.1. MariaDB
MariaDB is a relational database which converts data into structured information and provides an SQL interface for accessing data. It includes multiple storage engines and plug-ins, as well as geographic information system (GIS).
Red Hat Enterprise Linux 7 contains MariaDB 5.5 as the default implementation of a server from the MySQL databases family. Later versions of the MariaDB database server are available as Software Collections for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7. For more information about the latest versions, see the Release Notes for Red Hat Software Collections .
17.1.1. Installing the MariaDB server
To install the MariaDB server, follow this procedure:
Installing the MariaDB server
Ensure that the mariadb and mariadb-server packages are installed on the required server:
Start the mariadb service:
Enable the mariadb service to start at boot:
17.1.1.1. Improving MariaDB installation security
You can improve security when installing the MariaDB server by running the mysql_secure_installation command:
This command launches a fully interactive script, which prompts for each step in the process. The script enables to improve security in the following ways:
Setting a password for root accounts
Removing anonymous users
Disallowing remote (outside the local host) root logins
Removing test database
17.1.2. Configuring the MariaDB server for networking
To configure the MariaDB server for networking, use the [mysqld] section of the /etc/my.cnf.d/server.cnf file, where you can set the following configuration directives:
Bind-address is the address on which the server will listen.
Possible options are: a host name, an IPv4 address, or an IPv6 address.
Possible values are:
0 — to listen for all clients
1 — to listen for local clients only
The port on which MariaDB listens for TCP/IP connections.
17.1.3. Backing up MariaDB data
There are two main ways to back up data from a MariaDB database:
Logical backup
Physical backup
17.1.3.1. Logical back up
Logical backup consists of the SQL statements necessary to restore the data. This type of backup exports information and records in plain text files.
The main advantage of logical backup over physical backup is portability and flexibility. The data can be restored on other hardware configurations, MariaDB versions or Database Management System (DBMS), which is not possible with physical backups.
Logical backup can be performed only if the mariadb.service is running. Logical backup does not include log and configuration files.
17.1.3.2. Physical back up
Physical backup consists of copies of files and directories that store the content.
Physical backup has the following advantages compared to logical backup:
