duplicate命令中有pfile、logfile、*_file_name_convert、nofilenamecheck的案例

总结
1、pfile选项说明使用的rman命令执行的那端的一个文件
如果rman在源端开启，则pfile放在源端上，如果ramn在目标端开启，则pfile放在目标端上
2、logfile表示在duplicate命令中生成目标端的文件，和rman命令在哪端执行无关
logfile的生成的文件在目标端，logfile选项时必须指定size
3、一般操作时，除非自己清楚源端和目标端的datafile、online redo log文件不在同一个共享的目录中，否则不要加上nofilenamecheck
4、如果pfile或spifle中指定了*_file_name_convert参数，但是duplicate命令中重新指定了db_file_name_convert、logfile选择，则会覆盖掉pfile或spifle中指定了*_file_name_convert参数的设置，见如下logfile、*_file_name_convert、nofilenamecheck选项中5、6的实验

pfile选项
前提条件
源端端目标端在不同机器，不共享/u01/app/oracle/oradata/prod1路径，各自都有自己的/u01/app/oracle/oradata/prod1目录
源端的logfile位于路径/u01/app/oracle/oradata/prod1，目标端的pfile或spfile没有指定任何db_file_name_convert和log_file_name_convert参数

源端文件/home/oracle/initprod1std.ora(SGA=800M,process=200)
目标端pfile文件/home/oracle/initprod1std.ora(SGA=700M,process=190)
目标端pfile文件$ORACLE_HOME/dbs/initprod1std.ora(SGA=600M,process=180)
目标端spfile文件$ORACLE_HOME/dbs/spfileprod1std.ora(SGA=600M,process=180)

1、rman在源端服务器上执行，目标端没有/home/oracle/initprod1std.ora，目标端没有spfile，目标端使用$ORACLE_HOME/dbs/initprod1std.ora
run {
duplicate target database to prod1std from active database
pfile=/home/oracle/initprod1std.ora
LOGFILE
'/u02/log01.dbf' size 1024M,
'/u02/log02.dbf' size 1024M,
'/u02/log03.dbf' size 1024M
NOFILENAMECHECK;
}
目标端的结果
SGA=800M
process=200
db_data_files.file_name和源端一样
v$logfile.member路径为/u02
说明使用了源端的文件/home/oracle/initprod1std.ora，并且在目标端生成了rman命令中的logfile

2、rman在源端服务器上执行，目标端没有/home/oracle/initprod1std.ora，目标端有$ORACLE_HOME/dbs/initprod1std.ora，目标端使用spfile启动$ORACLE_HOME/dbs/spfileprod1std.ora
run {
duplicate target database to prod1std from active database
pfile=/home/oracle/initprod1std.ora
LOGFILE
'/u02/log01.dbf' size 1024M,
'/u02/log02.dbf' size 1024M,
'/u02/log03.dbf' size 1024M
NOFILENAMECHECK;
}
报错RMAN-05597: Database started with server parameter file and PFILE clause used in command

3、rman在源端服务器上执行，源端服务器上没有/home/oracle/initprod1std.ora，目标端没有/home/oracle/initprod1std.ora，目标端没有spfile，目标端使用$ORACLE_HOME/dbs/initprod1std.ora
run {
duplicate target database to prod1std from active database
pfile=/home/oracle/initprod1std.ora
LOGFILE
'/u02/log01.dbf' size 1024M,
'/u02/log02.dbf' size 1024M,
'/u02/log03.dbf' size 1024M
NOFILENAMECHECK;
}
报错RMAN-04017: startup error description: LRM-00109: could not open parameter file '/home/oracle/initprod1std.ora'

4、rman在源端服务器上执行，源端服务器上没有/home/oracle/initprod1std.ora，目标端有/home/oracle/initprod1std.ora，目标端没有spfile，目标端使用$ORACLE_HOME/dbs/initprod1std.ora
run {
duplicate target database to prod1std from active database
pfile=/home/oracle/initprod1std.ora
LOGFILE
'/u02/log01.dbf' size 1024M,
'/u02/log02.dbf' size 1024M,
'/u02/log03.dbf' size 1024M
NOFILENAMECHECK;
}
报错RMAN-04017: startup error description: LRM-00109: could not open parameter file '/home/oracle/initprod1std.ora'

3、4说明使用的是源端的文件/home/oracle/initprod1std.ora

logfile、*_file_name_convert、nofilenamecheck选项
源端端目标端在不同机器，不共享/u01/app/oracle/oradata/prod1路径，各自都有自己的/u01/app/oracle/oradata/prod1目录

1、源端的logfile位于路径/u01/app/oracle/oradata/prod1，目标端的使用spfile启动，spfile没有指定任何db_file_name_convert、log_file_name_convert参数
run {duplicate target database to prod1std from active database;}
报错

2、源端的logfile位于路径/u01/app/oracle/oradata/prod1，目标端的使用spfile启动，spfile没有指定任何db_file_name_convert、log_file_name_convert参数
run {duplicate target database to prod1std from active database nofilenamecheck;}
目标端的结果
db_data_files.file_name和源端一样
v$logfile.member和源端一样

3、源端的logfile位于路径/u01/app/oracle/oradata/prod1，目标端的使用spfile启动，spfile没有指定任何db_file_name_convert、log_file_name_convert参数
run {duplicate target database to prod1std from active database db_file_name_convert=('/u01/app/oracle/oradata/prod1','/u01/app/oracle/oradata/prod1std');}

4、源端的logfile位于路径/u01/app/oracle/oradata/prod1，目标端的使用spfile启动，spfile没有指定任何db_file_name_convert、log_file_name_convert参数
run {duplicate target database to prod1std from active database
db_file_name_convert=('/u01/app/oracle/oradata/prod1','/u01/app/oracle/oradata/prod1std')

5、源端的dbfile,logfile都位于路径/u01/app/oracle/oradata/prod1，目标端的使用spfile启动，spfile指定
db_file_name_convert='/u01/app/oracle/oradata/prod1/', '/u01/app/oracle/oradata/prod1std/'
log_file_name_convert='/u01/app/oracle/oradata/prod1/', '/u01/app/oracle/oradata/prod1std/'

v$logfile.member在/u01/app/oracle/oradata/prod1std路径下

6、源端的dbfile,logfile都位于路径/u01/app/oracle/oradata/prod1，目标端的使用spfile启动，spfile指定
db_file_name_convert='/u01/app/oracle/oradata/prod1/', '/u01/app/oracle/oradata/prod1std/'
log_file_name_convert='/u01/app/oracle/oradata/prod1/', '/u01/app/oracle/oradata/prod1std/'

}
目标端结果
db_data_files.file_name在/u01/app/oracle/oradata/data2目录下
v$logfile.member在/u01/app/oracle/oradata/data2路径下

logfile选项时不加size时报错

向AI问一下细节

duplicate命令中有pfile、logfile、*_file_name_convert、nofilenamecheck的案例
