问题

尝试锁定文件时, AIX 客户机报告锁定错误。该文件以前被同一客户端 / 进程锁定而没有错误。

如果客户端运行 Oracle ,则可能会报告以下错误:
Errors in file /mnt/oracle/udump/ora_20054240.trc:
ORA-01157: cannot identify/lock data file 201 - see DBWR trace file
ORA-01110: data file 201: '/mnt/oracle/tmp/XBR_TEMP01.dbf'

ORA-00210: cannot open the specified control file
ORA-00202: control file: '/mnt/oracle/control/control01.ctl'
ORA-27086: unable to lock file - already in use IBM AIX RISC System/6000 Error: 13: Permission denied Additional information: 8 Additional information: 57147422

数据包跟踪将显示存储系统正在响应 NLM 锁定呼叫(nlm.procedure_v4 == 2)并显示错误NLM_DENIED (nlm.stat == 1)。在存储系统发生故障转移、升级、节点重新引导或任何导致 NFS 服务器状态更改的类似行为后,将会发生此问题。
