oracle for sco安装指南
安装前准备 创建用户和组 # scoadmin-account manager-groups-add new group 创建 dba组 users-add new user 创建oracle用户,并把oracle用户添加到dba组去,更改Login group 为dba组 修改环境变量 用oracle用户登录 # su oracle 编辑.profile文件 $ vi .pro
安装前准备
创建用户和组
# scoadmin->account manager->groups->add new group
创建 dba组
users->add new user
创建oracle用户,并把oracle用户添加到dba组去,更改Login group 为dba组
修改环境变量
用oracle用户登录
# su – oracle
编辑.profile文件
$ vi .profile
在文件中加入下面几行
ORACLE_BASE=/u/oracle
ORACLE_HOME=/u/oracle/product/734
ORACLE_SID=oracle
ORACLE_TERM=ansi
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib
ORACLE_NLS32=$ORACLE_HOME/ocommon/nls/admin/data
ORACLE_PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/opt/bin:/usr/lbin:.
ULIMIT=2297152
TERM=ansi
TMPDIR=/u/tmp
PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin:/opt/bin:/usr/lbin:.
export ORACLE_BASE ORACLE_HOME ORACLE_SID

特殊设置
SCO505用户
需要打补丁oss459b
# mv oss459b /tmp/VOL.000.000
# custom->->Install New->From scosysv->Media Image
输入路径 /tmp
然后就OK了。
SCO507用户
$ su –
Passwd:
# cd /opt/K/SCO/unixds/5.2.0A/usr/ccs/lib
下面这两个文件不要弄丢了,装完后还要改回来
# mv crt0.o crt0.o.bak
# mv crt1.o crt1.o.bak
从SCO5.0.5的/opt/K/SCO/unixds/5.1.1A//lib下把这两个同名文件COPY过来。
建临时目录
$ su –
Passwd:
# mkdir /u/tmp
# chmod 777 tmp
# vi /etc/services
找到1521这个端口,把这一行用“#”注释掉,再添加一行
listener 1521/tcp
改核心参数
# /etc/conf/bin/idtune NBUF 20000
# /etc/conf/bin/idtune NHBUF 262144
# /etc/conf/bin/idtune NMPBUF 500
# /etc/conf/bin/idtune MAXUP 300
# /etc/conf/bin/idtune SEMMNI 70
# /etc/conf/bin/idtune SHMMAX 65536000
重新连接核心
# /etc/conf/cf.d/link_unix -y
# sync
# reboot

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 function in Oracle to calculate the number of days between two dates is DATEDIFF(). The specific usage is as follows: Specify the time interval unit: interval (such as day, month, year) Specify two date values: date1 and date2DATEDIFF(interval, date1, date2) Return the difference in days

The Oracle database startup sequence is: 1. Check the preconditions; 2. Start the listener; 3. Start the database instance; 4. Wait for the database to open; 5. Connect to the database; 6. Verify the database status; 7. Enable the service (if necessary ); 8. Test the connection.

The INTERVAL data type in Oracle is used to represent time intervals. The syntax is INTERVAL <precision> <unit>. You can use addition, subtraction, multiplication and division operations to operate INTERVAL, which is suitable for scenarios such as storing time data and calculating date differences.

To find the number of occurrences of a character in Oracle, perform the following steps: Get the total length of a string; Get the length of the substring in which a character occurs; Count the number of occurrences of a character by subtracting the substring length from the total length.

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.

The method of replacing strings in Oracle is to use the REPLACE function. The syntax of this function is: REPLACE(string, search_string, replace_string). Usage steps: 1. Identify the substring to be replaced; 2. Determine the new string to replace the substring; 3. Use the REPLACE function to replace. Advanced usage includes: multiple replacements, case sensitivity, special character replacement, etc.
