1.生产中升级了11.2.0.3到12.2.0.1数据库之后，启动ogg目标端复制进程，发现报错。

2.这个错误从表面上看，就是权限不足(1031-ORA-01031: insufficient privileges)。怎样定位问题。
在复制进程中加入如下参数。对执行的语句做10046的trace跟踪。
GGSCI (lxtrac03.iris.cl.sh.cos) 1> view params reputest
REPLICAT REPUTEST
setenv (NLS_LANG="AMERICAN_AMERICA.UTF8")

SQLEXEC "ALTER SESSION SET TRACEFILE_IDENTIFIER='OGG_DEBUG'"
SQLEXEC "ALTER SESSION SET EVENTS '10046 trace name context forever, level 12'"
GGSCI (lxtrac03.iris.cl.sh.cos) 2>
3.使用tkporf，格式化跟踪文件
[oracle@lxtrac03 trace]$ tkprof srw_ora_32062_OGG_DEBUG.trc aa.prf

可以明显看到引发报错ORA-01031语句。将语句放到sqlplus中执行。
[oracle@lxtrac03 trace]$ more aa.prf

在mos上面查找(1031-ORA-01031: insufficient privileges) user$ 。就发现有下列的文档
OGG-00665 OCI Error describe for query (status = 1031-ORA-01031: insufficient privileges) (文档 ID 2137888.1)
上面明确指出，rdbms从11g升到12c，但是goldengate还是在11.2。就会引发问题
+++++
Upgraded Oracle RDBMS from 11g to 12c, but Goldengate is still 11.2

解决方案；
conn / as sysdba
grant all on sys.user$ to <username>;
