OracleFaq (Oracle character set problem)_PHP tutorial
1. When building the database, catproc must be running, otherwise the following character set errors will occur when using rman: RMAN-00554: initialization of internal recovery manager package failed RMAN-04005: error from target database: ORA-06553: PLS- 213: package STANDARD noe RMAN-04015: error setting target database character set to ZHS16CGB231280 If there is no problem when building the database, you can Re-run catproc.sql. This will in turn call the dbmsbkrs.sql script which creates the dbms_backup_restore package. 2 , Chinese character set description ZHS16CGB231280 CGB2312-80 16-bit Simplified Chinese MB, ASCII ZHS16GBK GBK 16-bit Simplified Chinese MB, ASCII, UDC Simply put, ZHS16GBK is a superset of ZHS16CGB231280. The unified East Asian ideographic character set jointly developed by China, Japan, and South Korea in 1990 is often called the National Standard Extended Code Character Set (GBK). 3. How to avoid Chinese support problems. Our consistent suggestion is to plan well when building the database, so that there will be no problems in the future. 1) create database character set ZHS16GBK national character set ZHS16GBK 2) Environment variable: NLS_LANG=american_america.ZHS16GBK It is best to export NLS_DATE_FORMAT=YYYY-MM-DD HH24:MI:SS to specify the date format; 3) If props$ is specified when building the database The characterset must be ZHSS16GBK: NLS_CHARACTERSET ZHS16GBK NLS_NCHAR_CHARACTERSET ZHS16GBK If not, you can use update to change it, but doing so will have an impact on the existing data, and may even cause the entire database to become unusable, so it is better to verify it after building the database. A good The DBA can try to avoid problems from happening instead of waiting until problems arise and then put out the fire. In this way, there will no longer be problems with character sets and Chinese support. Still have questions? Contact me :)

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.

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.

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.
