由于raid卡bug故障,导致文件系统异常,从而使得数据库无法正常启动,客户找到我之前已经让多人分析,均未恢复成功,查看alert日志,发现他们恢复的时候尝试resetlogs库,然后报ORA-600 kcbzib_kcrsds_1错误

然后他们又重建了ctl,通过Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)检查,发现几个问题:
1. PDB$SEED不在该库记录中(由于该pdb中无业务数据,可以忽略)

---

2. 部分文件resetlogs 信息不正确(应该是对部分文件offline或者重建ctl的时候没有带上他们)

---

接手该库进行恢复,尝试resetlogs该库

主要错误有两个
ORA-01209: data file is from before the last RESETLOGS 和
ORA-65088: database open should be retried
通过分析这两个错误

[oracle@ora19c:/home/oracle]$ oerr ora 65088
65088, 00000, "database open should be retried"
// *Cause:   An inconsistency between the control file and the data dictionary
//           was found and fixed during the database open. The database open
//           needs to be executed again.
// *Action:  Retry the database open.
//
[oracle@ora19c:/home/oracle]$ oerr ora 01209
01209, 00000, "data file is from before the last RESETLOGS"   
// *Cause:  The reset log data in the file header does not match the   
//         control file. If the database is closed or the file is offline,  
//         the backup is old because it was taken before the last ALTER   
//         DATABASE OPEN RESETLOGS command. If opening a database that is   
//         open already by another instance, or if another instance just   
//         brought this file online, the file accessed by this instance is 
//         probably a different version. Otherwise, a backup of the file 
//         probably was restored while the file was in use.   
// *Action: Make the correct file available to the database. Then, either open
//         the database, or execute ALTER SYSTEM CHECK DATAFILES.  

ORA-65088参见官方:ORA-65088 while opening DB with resetlogs for multi-tenant DB in 12.2 (Doc ID 2449591.1),应该不是一个技术问题(由于重建ctl+resetlogs导致)
ORA-01209: data file is from before the last RESETLOGS 这个错误,可以简单理解resetlogs的信息比数据文件的checkpoint信息新,对于这种情况,以及结合上述的部分文件resetlogs信息不一致问题,索性直接使用m_scn小工具对其进行批量

---

再次使用Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)检查,确认resetlogs 问题修复

---

然后顺利打开数据库,并导出数据,完成本次恢复任务
