[日期：2012-12-12] 来源：Linux社区 作者：orcldb [字体：]
还原Oracle数据库时出现ORA-19870和ORA-19573错误，如：
RMAN> restore database;
Starting restore at 11-DEC-12
using channel ORA_DISK_1
channel ORA_DISK_1: starting datafile backupset restore
channel ORA_DISK_1: specifying datafile(s) to restore from backup set
restoring datafile 00001 to /u02/oradata/orcl/system01.dbf
restoring datafile 00002 to /u02/oradata/orcl/undotbs01.dbf
restoring datafile 00003 to /u02/oradata/orcl/sysaux01.dbf
restoring datafile 00004 to /u02/oradata/orcl/users01.dbf
restoring datafile 00005 to /u02/oradata/orcl/dolphin01.dbf
channel ORA_DISK_1: reading from backup piece /home/oracle/backup/dbf_07nsjs47_1_1.bak
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 12/11/2012 16:07:19
ORA-19870: error reading backup piece /home/oracle/backup/dbf_07nsjs47_1_1.bak
ORA-19573: cannot obtain exclusive enqueue for datafile 1
该问题的原因是由于数据库处于open状态导致的，将数据库置于mount状态该问题即可解决。

MySQL: String Data Types and CollationsMay 09, 2025 am 12:08 AMThe string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.
