xtts 跨平台迁移数据库
建议xtts目录和/rman 备份的路径目录都使用nfs共享 alter system set deferred_segment_creation=false sid=‘*‘ scope=spfile; ###########################增量临时文件在asm#########xtt.properties ########################## tablespaces=SPROD_TBS,IDX_TBS platformid=13 dfcopydir=/xttrman/full 本地全量备份数据的路径 backupformat=/xttrman/incr 本地增量备份数据的路径 stageondest=/xttrman/full 目标端所需要恢复数据的路径,后续生成的增量也要拷贝到这里 storageondest=+DATA/prod/datafile 目标端数据文件路径 -c 的时候放的位置 backupondest=+DATA/prod/datafile 目标端增量文件的临时路径，做完增量后会自动删除，如果放asm需要设置asm_home和asm_sid asm_home=/oracle/app/grid/product/11.2.0/grid asm_sid=+ASM parallel=2 rollparallel=2 getfileparallel=2 #############################建议使用这种方式，增量临时文件在文件系统######xtt.properties ####################### tablespaces=SPROD_TBS,IDX_TBS platformid=13 dfcopydir=/xttrman/full backupformat=/xttrman/incr stageondest=/xttrman/full storageondest=+DATA/prod/datafile backupondest=/xttrman/rec #asm_home=/oracle/app/grid/product/11.2.0/grid #asm_sid=+ASM parallel=2 rollparallel=2 getfileparallel=2 ########################################################################################### 源端全量备份脚本 cat full_backup.sh export TMPDIR=/oracle/soft/xttconvert perl xttdriver.pl -p 源端执行全量备份 sh full_backup.sh 生成文件 [oracle@localhost xttconvert]$ cat xttplan.txt SPROD_TBS::::967892 5 6 IDX_TBS::::967892 7 [oracle@localhost xttconvert]$ cat xttplan.txt SPROD_TBS::::967892 5 6 IDX_TBS::::967892 7 [oracle@localhost xttconvert]$ cat rmanconvert.cmd host ‘echo ts::SPROD_TBS‘; convert from platform ‘Linux x86 64-bit‘ datafile ‘/xttrman/full/SPROD_TBS_5.tf‘ ,‘/xttrman/full/SPROD_TBS_6.tf‘ format ‘+DATA/prod/datafile/%N_%f.dbf‘ parallelism 2; host ‘echo ts::IDX_TBS‘; convert from platform ‘Linux x86 64-bit‘ datafile ‘/xttrman/full/IDX_TBS_7.tf‘ format ‘+DATA/prod/datafile/%N_%f.dbf‘ parallelism 2; 目标端，执行恢复转换 vi convert.sh export XTTDEBUG=1 export TMPDIR=/oracle/soft/xttconvert perl xttdriver.pl -c sh convert.sh vi do_incr.sh export TMPDIR=/oracle/soft/xttconvert perl xttdriver.pl -i 源端增量备份 sh do_incr.sh [oracle@localhost xttconvert]$ cat xttplan.txt.new SPROD_TBS::::968168 5 6 IDX_TBS::::968196 7 [oracle@localhost xttconvert]$ cat tsbkupmap.txt IDX_TBS::7:::1=07u31cir_1_1 SPROD_TBS::5,6:::1=06u31ciq_1_1 注意每次做完增量 需要将增量的数据文件拷贝到全量备份的目录下，恢复完删除/xttrman/incr/* cp /xttrman/incr/* /xttrman/full/ 目标端增量恢复 vi restore_incr.sh export TMPDIR=/oracle/soft/xttconvert perl xttdriver.pl -r 注意如果增量恢复文件放在asm可能会出现以下错误，可以忽略，这个是xtts无法自动删除asm的临时文件 Can‘t locate strict.pm in @INC (@INC contains: /oracle/app/grid/product/11.2.0/grid/perl/lib/5.10.0/x86_64-linux-thread-multi /oracle/app/grid/product/11.2.0/grid/perl/lib/5.10.0 /oracle/app/grid/product/11.2.0/grid/perl/lib/site_perl/5.10.0/x86_64-linux-thread-multi /oracle/app/grid/product/11.2.0/grid/perl/lib/site_perl/5.10.0 /oracle/app/grid/product/11.2.0/grid/lib /oracle/app/grid/product/11.2.0/grid/lib/asmcmd /oracle/app/grid/product/11.2.0/grid/rdbms/lib/asmcmd /oracle/app/grid/product/11.2.0/grid/perl/lib/5.10.0/x86_64-linux-thread-multi /oracle/app/grid/product/11.2.0/grid/perl/lib/5.10.0 /oracle/app/grid/product/11.2.0/grid/perl/lib/site_perl/5.10.0/x86_64-linux-thread-multi /oracle/app/grid/product/11.2.0/grid/perl/lib/site_perl/5.10.0 /oracle/app/grid/product/11.2.0/grid/perl/lib/5.10.0/x86_64-linux-thread-multi /oracle/app/grid/product/11.2.0/grid/perl/lib/5.10.0/x86_64-linux-thread-multi /oracle/app/grid/product/11.2.0/grid/perl/lib/5.10.0 /oracle/app/grid/product/11.2.0/grid/perl/lib/site_perl/5.10.0/x86_64-linux-thread-multi /oracle/app/grid/product/11.2.0/grid/perl/lib/site_perl/5.10.0 /oracle/app/grid/product/11.2.0/grid/perl/lib/site_perl .) at /oracle/app/grid/product/11.2.0/grid/bin/asmcmdcore line 143.
