参考技术A 如何搭建dg 主库rac 备库单机
类型说明符 *函数名(形参表)

…… /*函数体*/

其中函数名之前加了“*”号表明这是一个指针型函数，即返回值是一个指针。类型说明符表示了返回的指针值所指向的数据类型。
如：
int *ap(int x,int y)

...... /*函数体*/

表示ap是一个返回指针值的指针型函数，它返回的指针指向一个整型变量。
【例10.32】本程序是通过指针函数，输入一个1～7之间的整数，输出对应的星期名。
main()
int i;
char *day_name(int n);
printf("input Day No:\n");
scanf("%d",&i);
if(i<0) exit(1);
printf("Day No:%2d-->%s\n",i,day_name(i));

char *day_name(int n)
static char *name[]= "Illegal day",

『ORACLE』DG搭建时备库的db_name报错

因为搭建DG时备库中的db_name为SBCD,实际应该是主库db_name的PROD1

所以在【主库】执行如下rman操作命令时会报错控制文件记录的数据库名与实际拷贝的数据库名不相同

RMAN> duplicate target database for standby from active database;

此时会在备库中生成control file，更改的如下：

1、更改备库中的db_name,关闭数据库生成spfile文件，在启动到nomount状态

[[email protected] SBDB]$ cd /u01/app/oracle/product/11.2.0/db_1/dbs/
[[email protected] dbs]$ vi initSBDB.ora

2、进入控制文件的路径下删除生成的控制文件

[[email protected] dbs]$ cd /u01/app/oracle/oradata/SBDB/
[[email protected] SBDB]$ ls
control01.ctl control02.ctl
[[email protected] SBDB]$ rm -rf *

3、主库重新连接rman，再次执行rman命令

RMAN> quit
