Oracle数据库监听器的问题
1、ORA-12541:TNS:没有监听器 原因:没有启动监听器或者监听器损坏。如果是前者,使用命令net start OracleOraHome81T
1、ORA-12541:TNS:没有监听器
原因:没有启动监听器或者监听器损坏。如果是前者,使用命令net start OracleOraHome81TNSListener(名字可能有出入)即可;
如果是后者,则使用“Net8 Configuration Assistant”工具向导之“监听程序配置”增加一个监听器即可(基本不用写任何信息,一路OK。在添加之前可能需要把所有的监听器先删除!)
2、ORA-12500:TNS:监听程序无法启动专用服务器进程
或
ORA-12560:TNS:协议适配器错误
原因:ORACLE的数据库服务没有启动。使用命令net start
ORACLESERVICEORADB(ORADB为数据库名字)即可。如果仍没有解决,
请继续向下看。
3、如果数据库服务启动失败,则很有可能是其注册表项值损坏,
最好的做法是以下两步:
1)ORADIM -DELETE -SID oradb 删除数据库服务项
2)ORADIM -NEW -SID oradb 新增数据库服务项
注:这个过程中如果出错,就重启计算机!
4、ORA-12154:TNS:能解析服务名
原因:ORACLE的网络服务名没有正确配置。请使用
Net8 Configuration Assistant”工具向导之“本地网络服务
名配置”配置TNS即可。如果仍没有解决,请继续向下看。
5、ORA-1034 :TNS:ORACLE不可用
原因:ORACLE的数据库服务正确启动,但是数据库没有打开!
使用命令:
1)svrmgrl 启动服务管理器
2)connect internal 以internal身份登陆
3)startup 打开数据库
6、ORA-12560:TNS:协议适配器错误(顽固性的)
原因:未知。
解决:必杀技--打开“Windows任务管理器”,杀死ORACLE.exe及ORADIM.exe进程,书写自己的ora_startup.bat,执行之!
PS:
1、我的ora_startup.bat:
net start OracleOraHome81TNSListener
net start ORACLESERVICEORADB
svrmgrl 一般情况下不用,不过有时少不了它的,,具体步骤见第5步。
2、我的ora_shutdown.bat:
net stop OracleOraHome81TNSListener
net stop ORACLESERVICEORADB
3、ORACLE相关服务名请参见“管理工具”之“服务”中以ORACLE开头的服务名。
用老办法command解决了。
具体如下:
执行:lsnrctl
然后start
接下来终于看到我的监听器启动了。

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.

Oracle database server hardware configuration requirements: Processor: multi-core, with a main frequency of at least 2.5 GHz. For large databases, 32 cores or more are recommended. Memory: At least 8GB for small databases, 16-64GB for medium sizes, up to 512GB or more for large databases or heavy workloads. Storage: SSD or NVMe disks, RAID arrays for redundancy and performance. Network: High-speed network (10GbE or higher), dedicated network card, low-latency network. Others: Stable power supply, redundant components, compatible operating system and software, heat dissipation and cooling system.

The amount of memory required for an Oracle database depends on the database size, workload type, and number of concurrent users. General recommendations: Small databases: 16-32 GB, Medium databases: 32-64 GB, Large databases: 64 GB or more. Other factors to consider include database version, memory optimization options, virtualization, and best practices (monitor memory usage, adjust allocations).

To create a scheduled task in Oracle that executes once a day, you need to perform the following three steps: Create a job. Add a subjob to the job and set its schedule expression to "INTERVAL 1 DAY". Enable the job.

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

Oracle listeners are used to manage client connection requests. Startup steps include: Log in to the Oracle instance. Find the listener configuration. Use the lsnrctl start command to start the listener. Use the lsnrctl status command to verify startup.
