我正在尝试使用 RMAN Duplicate Target Database For Standby Dorecover 在 Data Guard 配置中构建备用数据库。
所有 rman 备份集都在 Netbackup 中，我可以使用 RMAN 视图查看备份片段的清单。
但是，复制目标数据库命令失败并显示：
channel p4: starting datafile backup set restore
channel p4: restoring control file
channel p4: reading from backup piece c-2404308342-20160306-02
channel p4: ORA-19870: error while restoring backup piece c-2404308342-20160306-02
ORA-19507: failed to retrieve sequential file, handle="c-2404308342-20160306-02", parms=""
ORA-27029: skgfrtrv: sbtrestore returned error
ORA-19511: Error received from media manager layer, error text:
Backup file <c-2404308342-20160306-02> not found in NetBackup catalog
基本上，备份片段在那里，但 RMAN/Netbackup 说它们不在那里。
你知道为什么吗？
谢谢你。
