ORA-02192：PCTINCREASE不允许用于回滚段存储子句
官方解释
此时出现ORA-02192错误，是因为使用了不允许用于回滚段存储子句的PCTINCREASE参数。
常见案例
一般情况下，当创建回滚段时，错误ORA-02192通常会因使用了PCTINCREASE参数而出现：
SQL> CREATE ROLLBACK SEGMENT r1
STORAGE ( INITIAL 64K PCTINCREASE 0 ) ;
CREATE ROLLBACK SEGMENT r1
*
ERROR at line 1:
ORA-02192: PCTINCREASE not allowed for rollback segment storage clauses
正常处理方法及步骤
要解决ORA-02192错误，请删除PCTINCREASE参数：
SQL> CREATE ROLLBACK SEGMENT r1
STORAGE ( INITIAL 64K );
Rollback segment created.
