SQL> @ddl_setup Oracle GoldenGate DDL Replication setup script Verifying that current user has privileges to install DDL Replication... You will be prompted for the name of a schema for the Oracle GoldenGate database objects. NOTE: For an Oracle 10g source, the system recycle bin must be disabled. For Oracle 11g and later, it can be enabled. NOTE: The schema must be created prior to running this script. NOTE: Stop all DDL replication before starting this installation. Enter Oracle GoldenGate schema name:goldengate Working, please wait ... Spooling to file ddl_setup_spool.txt Checking for sessions that are holding locks on Oracle Golden Gate metadata tables ... Check complete. declare * ERROR at line 1: ORA-20783: ORA-20783: Oracle GoldenGate DDL Replication setup: *** Please move GOLDENGATE to its own tablespace ORA-06512: at line 34 I've read the script, it seems that the problem can be fixed like this: $export ALLOW_SHARED_TABLESPACE='TRUE'
其实export ALLOW_SHARED_TABLESPACE='TRUE' 这个方法不是好方法。
GoldenGate 对DDL的配置要求如下:
As explained in install doc, http://docs.oracle.com/cd/E35209_01/doc.1121/e35957.pdf "Create a default tablespace for the Oracle GoldenGate DDL schema. This tablespace must be dedicated to the DDL schema; do not allow any other schema to share it. AUTOEXTEND must be set to ON for this tablespace, and the tablespace must be sized to accommodate the growth of the GGS_DDL_HIST and GGS_MARKER tables. The GGS_DDL_HIST table, in particular, will grow in proportion to overall DDL activity."

MySQL中的字符串数据类型包括CHAR、VARCHAR、BINARY、VARBINARY、BLOB、TEXT,排序规则(Collations)决定了字符串的比较和排序方式。1.CHAR适合固定长度字符串,VARCHAR适合可变长度字符串。2.BINARY和VARBINARY用于二进制数据,BLOB和TEXT用于大对象数据。3.排序规则如utf8mb4_unicode_ci忽略大小写,适合用户名;utf8mb4_bin区分大小写,适合需要精确比较的字段。

最佳的MySQLVARCHAR列长度选择应基于数据分析、考虑未来增长、评估性能影响及字符集需求。1)分析数据以确定典型长度;2)预留未来扩展空间;3)注意大长度对性能的影响;4)考虑字符集对存储的影响。通过这些步骤,可以优化数据库的效率和扩展性。
