记一次安装mysql到oracle ogg同步的问题汇总

问题1：

GGSCI (cs-db) 1> dblogin SOURCEDB [email protected]:3306, USERID ggs, PASSWORD "oracle"

2019-03-05 15:49:50  WARNING OGG-00769  MySQL Login failed: . SQL error (2059). Authentication plugin 'caching_sha2_password' cannot be loaded: /usr/local/mysql/lib/plugin/caching_sha2_password.so: cannot open shared object file: No such file or directory.
ERROR: Failed to connect to MySQL database engine for HOST 133.37.126.38, DATABASE mydb, USER ggs, PORT 3306.
mysql登陆成功，ogg登陆失败
#更新密码（mysql_native_password模式）    
ALTER USER 'ggs'@'%' IDENTIFIED WITH mysql_native_password BY 'oracle';

问题2：
GGSCI (cs-db DBLOGIN as ggs) 9> start mgr
Process creation error: Cannot find executable file './mgr'

没有进入ogg根目录 start mgr导致

问题3：mysql没有集成模式,oracle 12c pdb必须使用集成模式
GGSCI (cs-db) 7> ADD EXTRACT extmy,integrated tranlog, begin now 
ERROR: Invalid parameter specified for ADD EXTRACT.

问题4：extinit启动报错
WARNING OGG-01194  EXTRACT task repinimy abended : Source wildcard specification JAM.my.* includes a catalog name, but the source table name mydb.t1 does not include a catalog name.
不能写SOURCECATALOG JAM
正确写法如下：
MAP my.*,target jam.lzl.*;
