How to solve the slow creation of tablespaces in Oracle?

There are several ways to try to solve the problem of slow tablespace creation in Oracle: 1. Check system resources: make sure the database server has enough memory and disk space to handle the tablespace creation operation. If resources are insufficient, performance can be improved by adding memory or disk space. 2. Optimize disk performance: if the tablespace creation operation involves a lot of disk reads and writes, consider using faster disk drives or configuring RAID to improve disk performance. 3. Check the initial size of the tablespace: when creating a tablespace, try specifying a larger initial size to reduce the number of times the tablespace needs to expand, thereby improving performance. 4. Analyze and optimize the storage parameters of the tablespace: when creating a tablespace, set appropriate storage parameters such as block size, data file size, and autoextend based on the characteristics and requirements of the database to improve performance. 5. Adjust Oracle database parameters: optimize tablespace creation performance by modifying Oracle database parameters, such as increasing SGA and PGA sizes appropriately, adjusting buffer and log parameters, etc. 6. Check and optimize network connections: if tablespace creation involves network transmission, check the speed and stability of the network connection and optimize network configuration to improve performance. 7. Use parallel creation: in Oracle databases, utilize parallel tablespace creation functionality to execute creation operations using multiple processes simultaneously, speeding up the process. 8. Consider using pre-created tablespaces: in versions of Oracle 12c and later, utilize the pre-create tablespace feature to create tablespaces beforehand during database creation, avoiding performance issues with creating tablespaces at runtime. The above are some common methods to solve the problem of slow tablespace creation. Depending on the specific situation, choose the appropriate method. If the problem persists, consider contacting Oracle official technical support for further assistance.
