【问题描述】*：查询日志备份集的db_magic为负数导致恢复语句语法不通过，以下是执行的语句

1. /opt/xfyb-dameng-linux-4.1.2/bin/job_logs/database/DmServiceDMSERVER/recovery/DmServiceDMSERVER_FULL_BAK_11_mapped_file.txt
2. /opt/dmdbms/bin/dmrman CTLSTMT=“RESTORE DATABASE ‘/opt/dmdbms/data/DAMENG/dm.ini’ FROM BACKUPSET ‘/nfs/246/11/DmServiceDMSERVER_FULL_BAK_11’ MAPPED FILE ‘/opt/xfyb-dameng-linux-4.1.2/bin/job_logs/database/DmServiceDMSERVER/recovery/DmServiceDMSERVER_FULL_BAK_11_mapped_file.txt’”
3. /opt/dmdbms/bin/dmrman CTLSTMT=“RESTORE ARCHIVELOG FROM BACKUPSET ‘/nfs/246/11/DmServiceDMSERVER_AUTO_LOG_BAK_11_1’ ALL TO ARCHIVEDIR ‘/opt/dmdbms/data/DAMENG/arch’”
4. /opt/dmdbms/bin/dmrman CTLSTMT=“RESTORE ARCHIVELOG FROM BACKUPSET ‘/nfs/246/11/DmServiceDMSERVER_AUTO_LOG_BAK_11_2’ ALL TO ARCHIVEDIR ‘/opt/dmdbms/data/DAMENG/arch’”
5. 查询/nfs/246/11/DmServiceDMSERVER_AUTO_LOG_BAK_11_2的DB_MAGIC为-78086660
6. [/opt/dmdbms/bin/dmrman CTLSTMT=“RECOVER DATABASE ‘/opt/dmdbms/data/DAMENG/dm.ini’ WITH ARCHIVEDIR ‘/opt/dmdbms/data/DAMENG/arch’ USE DB_MAGIC -78086660 UNTIL TIME ‘2021-01-07 13:08:41’”
