oracle RAC listener服务启动错误 Linux Error: 111
不知道怎么回事grid安装了之后其中一个节点的listener就是起不来，报错如下： [grid@rac22 ~]$ lsnrctl status LSNRCTL for Linux: Version 11.2.0.1.0 Production on 23-AUG-2013 10:31:27 Copyright (c) 1991, 2009, Oracle. All rights reserved. Connect

Linux Error: 111: Connection refused
修改监听配置文件listener.ora,重启server，问题依旧，最后谷歌发现hosts文件修改之后会出现这个问题。
修改/etc/hosts文件，加入以下内容
127.0.0.1 localhost.hostdomain localhost
问题解决。
[grid@rac22 ~]$ srvctl start listener -n rac22
监听启动

How long will Oracle database logs be kept?
May 10, 2024 am 03:27 AM
The retention period of Oracle database logs depends on the log type and configuration, including: Redo logs: determined by the maximum size configured with the "LOG_ARCHIVE_DEST" parameter. Archived redo logs: Determined by the maximum size configured by the "DB_RECOVERY_FILE_DEST_SIZE" parameter. Online redo logs: not archived, lost when the database is restarted, and the retention period is consistent with the instance running time. Audit log: Configured by the "AUDIT_TRAIL" parameter, retained for 30 days by default.

The amount of memory required by Oracle depends on database size, activity level, and required performance level: for storing data buffers, index buffers, executing SQL statements, and managing the data dictionary cache. The exact amount is affected by database size, activity level, and required performance level. Best practices include setting the appropriate SGA size, sizing SGA components, using AMM, and monitoring memory usage.
