NBU異機(jī)還原oracle問題分析

這篇文章主要介紹“NBU異機(jī)還原oracle問題分析”，在日常操作中，相信很多人在NBU異機(jī)還原oracle問題分析問題上存在疑惑，小編查閱了各式資料，整理出簡單好用的操作方法，希望對大家解答”NBU異機(jī)還原oracle問題分析”的疑惑有所幫助！接下來，請跟著小編一起來學(xué)習(xí)吧！

今天在執(zhí)行nbu恢復(fù)oracle的問題，發(fā)現(xiàn)總是出現(xiàn)問題
恢復(fù)腳本是沒問題的
RMAN> run
{
allocate channel c1 type 'sbt_tape';
send 'NB_ORA_CLIENT=mytest1';
restore controlfile from '/cntrl_6255_1_880381344';
release channel c1;
}

using target database control file instead of recovery catalog
allocated channel: c1
channel c1: SID=59 device type=SBT_TAPE
channel c1: Veritas NetBackup for Oracle - Release 7.6 (2013111313)

sent command to channel: c1

Starting restore at 22-MAY-15

channel c1: restoring control file
released channel: c1
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 05/22/2015 14:45:16
ORA-19870: error while restoring backup piece /cntrl_6255_1_880381344
ORA-19507: failed to retrieve sequential file, handle="/cntrl_6255_1_880381344", parms=""
ORA-27029: skgfrtrv: sbtrestore returned error
ORA-19511: Error received from media manager layer, error text:
   Backup file </cntrl_6255_1_880381344> not found in NetBackup catalog
  
但通過bplist從nbu備份服務(wù)器上查看也是可以看到的，但就是報(bào)這個(gè)錯(cuò)，經(jīng)過分析，感覺可能是用戶的問題，原來備份時(shí)的用戶是oracle，而現(xiàn)在的恢復(fù)環(huán)境是oratest。所以新建新建一個(gè)oracle用戶來，建好后對oracle用戶授好權(quán)后，再恢復(fù)報(bào)如下錯(cuò)誤：
RMAN> run
{
allocate channel c1 type 'sbt_tape';
send 'NB_ORA_CLIENT=mytest1';
restore controlfile from '/cntrl_6255_1_880381344';
release channel c1;
}

using target database control file instead of recovery catalog
allocated channel: c1
channel c1: SID=59 device type=SBT_TAPE
channel c1: Veritas NetBackup for Oracle - Release 7.6 (2013111313)

sent command to channel: c1

Starting restore at 25-MAY-15

RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 05/25/2015 17:23:18
RMAN-06172: no AUTOBACKUP found or specified handle is not a valid copy or piece

后來經(jīng)過咨詢nbu的工程師，得到了答案！

原因是：
1、ORACLE_HOME的屬主，要與原環(huán)境相同。也就是說原環(huán)境中是oracle用戶，那么新環(huán)境也必須是oracle
2、在使用oracle_link鏈接時(shí)，必須是使用與原環(huán)境相同的用戶進(jìn)行執(zhí)行
2、恢復(fù)時(shí)，使用的執(zhí)行用戶，必須與原環(huán)境相同的用戶。
