NBU异机恢复Oracle数据库，作业报错2850处理

一、sbttest 命令，测试通道的有效性

[oracle@db1 dbs]$ sbttest sbt_tape
The sbt function pointers are loaded from libobk.so library.
-- sbtinit succeeded
-- sbtinit (2nd time) succeeded
sbtinit: Media manager supports SBT API version 2.0
sbtinit: Media manager is version 5.0.0.0
sbtinit: vendor description string=Veritas NetBackup for Oracle - Release 8.0 (2016110921)
sbtinit: allocated sbt context area of 8 bytes
sbtinit: proxy copy is supported
-- sbtinit2 succeeded
-- regular_backup_restore starts ................................
MMAPI error from sbtbackup: 7501, VxBSACreateObject: Failed with error:
Server Status: the specified policy does not exist in the configuration database
-- sbtbackup failed

检查 rman恢复归档日志失败的原因不是oracle的问题，还是介质管理的问题。

二、client attributes

测试机上rman target / 报错返回，master上没作业记录

using target database control file instead of recovery catalog
allocated channel: ch00
channel ch00: sid=36 devtype=SBT_TAPE
channel ch00: Veritas NetBackup for Oracle - Release 8.0 (2016010419)
sent command to channel: ch00
Starting restore at 19-JUN-20
released channel: ch00
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 06/19/2020 2:22:56
ORA-27191: sbtinfo2 returned error
Additional information: 2

master上修改master server属性,选择client attributes
allow client browse和allow client restore 选上。。。问题依旧。

重点是clients那里，添加主机，即可。

三、status 48: client hostname could not be found

报错不明显，查看详情发现提示 status 48: client hostname could not be found

五、最终恢复成功

主机允许异机恢复

/etc/hosts解析要有

/usr/openv/netbackup/bp.conf 要有

看输出看输出看输出~~~日志很重要
