**背景：恢复数据库控制文件报错** **报错内容如下：** ```bash RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of restore command at 06/30/2021 10:44:56 ORA-27191: sbtinfo2 returned error Additional information: 3480 RMAN> Recovery Manager complete. ``` **卸载重新安装NBU8.1客户端** ```bash 卸载步骤 # rpm -e VRTSnbclt error: Failed dependencies: VRTSnbclt >= 8.1.1.0 is needed by (installed) VRTSnbjava-8.1.1.0-1517731851.x86_64 VRTSnbclt >= 8.1.1.0 is needed by (installed) VRTSnbcfg-8.1.1.0-1517731820.x86_64 先卸载两个依赖包 # rpm -e VRTSnbjava-8.1.1.0-1517731851.x86_64 # rpm -e VRTSnbcfg-8.1.1.0-1517731820.x86_64 NBU客户端服务可以不用停在卸载 # rpm -e VRTSnbclt 再删除安装目录/usr/openv # rm -rf /usr/openv ``` **安装NBU8.1客户端** ```bash 需要重新获取token（这边获取需要找管理NBU服务器人员重新获取） 1.删除之前NBU Server上的缓存（10.20.142.1） # /usr/openv/netbackup/bin/bpclntcmd -clear_host_cache 2.在克隆的NBU客户端上执行/usr/openv/netbackup/bin/nbcertcmd -deleteAllCertificates 删除已有的认证，此步骤可能需要停止NBU服务或者卸载重装二选一 3.检查是否能获取CA证数认证 # /usr/openv/netbackup/bin/nbcertcmd -getCAcertificate CA certificate stored successfully from server GD-PS-NBUAP. 4.这一步不要卸载将新获取的token输入进入 # /usr/openv/netbackup/bin/nbcertcmd -getCertificate -token -server GD-PS-NBUAP Authorization Token: 输入新获取的token 5.检查是否与NBU Server建立连接输出如下内容 # /usr/openv/netbackup/bin/bpclntcmd -pn expecting response from server GD-PS-NBUAP GDVADMTOLBDB *NULL* 10.20.30.174 51290 6.查看NBU Client版本 # more /usr/openv/netbackup/bin/version NetBackup-SuSE3.0.76 8.1.1 ``` 重新获取的token安装客户端还是报错 ==到NBU Server服务器上查看原因是另一台主机10.20.30.174对应之前的主机名GDVUOLBDB现在主机名修改成GDVADMTOLBDB删除之前的对应内容== 再重新获取token安装
