To enable automatic resizing of Oracle tablespaces, you can follow these steps:<\/p>\n

    \n
  1. Identify the type of tablespace: Decide on the type of tablespace, either datafile tablespace or temporary tablespace, for configuring automatic expansion.<\/li>\n
  2. To enable autoextend for a tablespace, use the ALTER TABLESPACE statement. For example, to set autoextend for a data file tablespace, you can use the following command:<\/li>\n
  3. Turn on the autoextend feature for the specified tablespace.<\/li>\n
  4. For temporary tablespace, you can use the following command:<\/li>\n
  5. Change the tablespace named ‘\u8868\u7a7a\u95f4\u540d\u79f0’ to automatically extend the tempfile located at ‘\u6587\u4ef6\u8def\u5f84’.<\/li>\n
  6. Configure the autoextend parameters of the tablespace by using the ALTER DATABASE command. For example, to set the autoextend increment of the data file tablespace to 100MB, you can use the following command:<\/li>\n
  7. Enable autoextend for the datafile ‘\u6570\u636e\u6587\u4ef6\u8def\u5f84’ with an increment of 100MB, and set the maximum size to unlimited.<\/li>\n
  8. You can use the following command for temporary tablespace:<\/li>\n
  9. Enable the automatic extension of the TEMPFILE at the specified file location, increasing by 100M each time and with no maximum size limit.<\/li>\n
  10. In the above command, the number after NEXT represents the increment size for automatic expansion, while the MAXSIZE parameter specifies the maximum size of the table space, with “unlimited” indicating no limit.<\/li>\n
  11. To verify if the configuration is effective, you can use the following command to check if the automatic space expansion settings for the table space are in effect:<\/li>\n
  12. Choose the file name, autoextensible setting, and maximum size in bytes from the DBA_DATA_FILES table where the tablespace name is ‘\u8868\u7a7a\u95f4\u540d\u79f0’.<\/li>\n
  13. For temporary tablespace, the following command can be used:<\/li>\n
  14. Retrieve the file name, autoextend settings, and maximum size of temporary files from the DBA_TEMP_FILES table where the tablespace name is ‘\u8868\u7a7a\u95f4\u540d\u79f0’.<\/li>\n
  15. If the value of the AUTOEXTENSIBLE column is YES and the value of the MAXBYTES column is greater than 0, it means the configuration is effective.<\/li>\n<\/ol>\n

    Note: When setting up automatic tablespace expansion, ensure that the file system has enough available space to support the automatic expansion operation.<\/p>\n","protected":false},"excerpt":{"rendered":"
