查看已有VG
#lsvg
rootvg
oravg
datavg
查看每个VG使用状态
#lsvg oravg
重点关注几个值
PP SIZE: 512 megabyte(s) 注释:每个PP大小
FREE PPs: 147 (75264 megabytes) 注释:剩余pp数及空间大小
#lsvg datavg
PP SIZE: 512 megabyte(s)
FREE PPs: 3974 (2034688 megabytes)
查看当前lv建立的数目
#lsvg -l rootvg 注释:rootvg上面没有关于数据库的lv
#lsvg -l oravg
........... ... ... ... . .......... ...
lv_users_49 raw 128 128 1 open/syncd N/A
lv_users_50 raw 128 128 1 open/syncd N/A
lv_users_51 raw 128 128 1 open/syncd N/A
lv_users_52 raw 128 128 2 open/syncd N/A
#lsvg -l datavg
datavg:
LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT
lv_users_53 raw 128 128 1 open/syncd N/A
lv_users_54 raw 128 128 1 open/syncd N/A
lv_users_55 raw 128 128 1 open/syncd N/A
lv_users_56 raw 128 128 1 open/syncd N/A
lv_users_57 raw 128 128 1 open/syncd N/A
lv_users_58 raw 128 128 1 open/syncd N/A
lv_users_59 raw 128 128 1 open/syncd N/A
lv_users_60 raw 128 128 1 open/syncd N/A
查看完成后,新的lv从lv_users_61开始建
例如:
在oravg下建十块lv,每块大小64g,名字为
lv_users_61 lv_users_62 lv_users_63 ... ... lv_users_64
PP_Size=512M,64G/PP_Size=128(NumPPs)
命令格式:
"/usr/sbin/mklv -y LVname -T O -w n -s n -r n VGname NumPPs"
#mklv -y lv_users_61 -t 'raw' -T O -w n -s n -r n datavg 128
#mklv -y lv_users_62 -t 'raw' -T O -w n -s n -r n datavg 128
#mklv -y lv_users_63 -t 'raw' -T O -w n -s n -r n datavg 128
... ...
#mklv -y lv_users_70 -t 'raw' -T O -w n -s n -r n datavg 128
修改rlv块设备权限
#cd /dev/
#ls -l rlv_user_60 查看以前块设备权限
#ls -l rlv_user_61 查看刚才新建的块设备权限
#chown Oracle:dba rlv_user_61
#chown oracle:dba rlv_user_62
#chown oracle:dba rlv_user_63
... ...
#chown oracle:dba rlv_user_70
然后加到表空间 Usersoracle加空间命令
#su - oracle
$sqlplus /nolog
$conn sys/oracle as sysdba;
进入sqlplus
>ALTER TABLESPACE "USERS" ADD DATAFILE '/dev/rlv_users_61' SIZE 65500M REUSE;
>ALTER TABLESPACE "USERS" ADD DATAFILE '/dev/rlv_users_62' SIZE 65500M REUSE;
>ALTER TABLESPACE "USERS" ADD DATAFILE '/dev/rlv_users_63' SIZE 65500M REUSE;
... ...
>ALTER TABLESPACE "USERS" ADD DATAFILE '/dev/rlv_users_70' SIZE 65500M REUSE;
逐个添加,输入加空间命令之后耐心等待,直至出现添加成功的提示之后方可输入下一条
添加命令。
添加完成后检查表空间,,确认添加已经成功!

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.

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 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 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.
