Oracle RAC内部错误:ORA-00600[kjbmprlst:shadow]一例

一套Linux x86-64上的11.2.0.1 4节点RAC系统中LMS GCS服务进程遭遇到内部错误ORA-00600[kjbmprlst:shadow],导致节点实例意外终止,具体日志如下:

    ORA-600 [KJBRREF:PKEY]
    ORA-600 [KJBRASR:PKEY] 

    RAC (Real Application Clusters) / OPS 

Description

    A lock is closed without sending a message to the master.
    This causes closed lock dangling at the master crashing the instance with different internal errors.

    Reported internal errors so far are :
    - KJBMPRLST:SHADOW
    - KJBMOCVT:RID
    - KJBRREF:PKEY
    - KJBRASR:PKEY

该kjbmprlst:shadow内部函数用以管理kjbm shadow锁(/libserver10.a/kjbm.o )信息,存在某个已关闭的lock没有及时message给master node的代码漏洞,目前除了安装补丁外没有已验证的workaround办法(disable drm似乎是无效的):

PCM DLM locks that are owned by the local instance are allocated and embedded in an LE structure.
PCM DLM locks that are owned by remote instances and mastered by the local instance are allocated in SHARED_POOL.

PCM Locks and Resources
Fields of interest in the kclle structure: kcllerls or releasing; kcllelnm or name(id1,id2);
kcllemode or held-mode; kclleacq or acquiring; kcllelck or DLM lock.

Fields of interest in the kjbr structure: resname_kjbr[2] or resource name; grant_q_kjbr or grant queue;
convert_q_kjbr or convert queue; mode_role_kjbr, which is a bitwise merge of grant mode and
role-interpreted NULL(0x00), S(0x01), X(0x02), L0 Local (0x00), G0 Global without PI (0x08), G1 Global with PI (0x018).

The field mode_role_kjbl in kjbl is a bitwise merge of grant, request, and lock mode: 0x00 if grant NULL;
0x01 if grant S; 0x02 if grant X; 0x04 lock has been opened at master; 0x08 if global role (otherwise local);
0x10 has one or more PI; 0x20 if request CR; 0x40 if request S; 0x80 if request X.

Someone has to keep a list of all buffers and where they are mastered
This is called Global Resource Directory (GRD)
GRD is present on all the instances of the cluster
To find out the master:
select  b.dbablk, r.kjblmaster master_node
from x$le l, x$kjbl r, x$bh b
where b.obj =
and b.le_addr = l.le_addr
and l.le_kjbl = r.kjbllockp

Oracle Support宣称可以通过11.2.0.2 (Server Patch Set)11.2.0.1 Bundle Patch 4 for Exadata Database修复该bug,但是有迹象表明在11.2.0.2上仍可能发生该ORA-00600[kjbmprlst:shadow]内部错误,同时该bug更多地发生在超过2个节点的RAC系统中。

    PROBLEM:
    --------
    One of the instances in this RAC crashed with ORA-600: [kjbmprlst:shadow]
    
    DIAGNOSTIC ANALYSIS:
    --------------------
    It seems like 9979039 is a prime candidate as the source of the problem.
    
    But due to the fact that the stack trace in this case doesn't match, we 
    are filing this bug to get confirmation.
    
    WORKAROUND:
    -----------
    None

    REPRODUCIBILITY:
    ----------------

    TEST CASE:
    ----------
    Comcast has attempted to upload the ISP files several times, but what is
    available is not complete.

    on April 18 customer applied patch 10121589 (in merge Patch  10387939) to fix 
    the error but still the customer has been hitting this. Recent occurance is

    PROBLEM:
    ——–
    1. Clear description of the problem encountered:

    – frequent instance crashes due to LMD crashing with :

    ORA-600: internal error code, arguments: [kjmscndscq:timeout]

    – 4 instances, 11.2.0.1 on Linux X86_64
    – Oracle RDS/IP (generic)
    – rds-tools Package 1.4-1 11-SEP-09
    – Using Infiniband

    – For example : Mar 18 at 02.06 inst#2 crashed :

    Instance terminated by LMD0, pid = 7935

    2. Sequence of events leading to the problem

    – Has seen it happen when :

    1) When RMAN was backing up the FRA to tape (netbackup).
    2) running a select on a large table that has thousands of inserts per
    second.

    3. Technical impact on the customer. Include persistent after effects.

    – Instances restart.

    – It looks like it’s in mid-DRM and LMD is trying to get an RM enqueue, but I
    can’t see the holder of this resource on the other instances though.

    WORKAROUND:

    – Suggested ct. disable DRM for now to get some stability, waiting for

    Wait event of “lock deadlock retry” is set in kcbgcur ( KCB: Get a block in
    current mode)

    and from 10046 there are many tried per waiting on ‘ges message buffer
    allocation’

    There seeme to be 2 issues here:

    1. The wait on GES message buffer allocation is set up even when there is
    no need to wait in kjcsmba.

    The root cause seems related to ‘ges message buffer allocation’

    bug 8630374 has same issue fixed in 12.1 ( Distributed Lock Manager (DLM)
    issue )

    REDISCOVERY INFORMATION:
    Check if there are a large number of wait event of “ges message buffer
    allocation” with very small elapse time when Event 10046 level 8 is set.

    2. WAIT #2: nam=’lock deadlock retry’ ela= 10600 p1=0 p2=0 p3=0 obj#=16540
    tim=1272818183618017

    This wait is more serious and has much higher impact.

    WORKAROUND:
