MySQL数据迁移到Oracle记录
MySQL: utf-8字符集Oracle: Al32UTF8步骤:1. 从mysql导出csv格式数据,导出时设置default_character_set=gbk,否则会乱码2.上传
MySQL: utf-8字符集
Oracle: Al32UTF8
步骤:
1. 从mysql导出csv格式数据,,导出时设置default_character_set=gbk,否则会乱码
2.上传至linux服务器(oracle服务器),用以下命令将windows的\r\n换成\r:
sed -i "s/\r//g" file
3.将gbk编码转为utf8编码:
iconv -f gb18030 -t utf-8 file1.txt > file2.txt
4.编写sql loader控件文件(file.ctl):
options (skip=1)
load data
CHARACTERSET AL32UTF8
infile 'terminal.txt'
badfile 'terminal.err'
discardfile 'terminal.dis'
replace into table terminal
fields terminated by ',' TRAILING NULLCOLS
(
id,
mobile,
imsi,
imei,
evoketime date "yyyy-mm-dd hh24:mi:ss",
province,
city,
evokenum,
createtime date "yyyy-mm-dd hh24:mi:ss",
project_id,
carrier,
ip,
sc,
new_imsi,
new_imei
)
5. 运行sqlldr导入到oracle数据库:
sqlldr user/pass@db -control=file.ctl

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.

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 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.

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.

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).

Oracle Database memory requirements depend on the following factors: database size, number of active users, concurrent queries, enabled features, and system hardware configuration. Steps in determining memory requirements include determining database size, estimating the number of active users, understanding concurrent queries, considering enabled features, and examining system hardware configuration.

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())

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.
