Question

我正在运行sybase ASE Adaptive Server Enterprise/15.0.3/EBF 17690 ESD#1.1 RELSE/P/Solaris AMD64/OS 5.10/ase1503/2681/64-bit/FBO/Thu Aug 20 15:37:40 2009并面临一个奇怪的问题。

当删除不存在的索引时，我会无限期地挂起：

1> sp_helpindex TABLE#DATA#DEALIRD_DBF
2> go
Object has the following indexes

 index_name  index_keys index_description    index_max_rows_per_page index_fillfactor index_reservepagegap index_created       index_local
 ----------- ---------- -------------------- ----------------------- ---------------- -------------------- ------------------- ------------
 DEALIRD_ND0  M_NB      nonclustered, unique                       0                0                    0 Oct  1 2012 10:20AM Global Index

(1 row affected)
 index_ptn_name         index_ptn_seg
 ---------------------- -------------
 DEALIRD_ND0_2038047761 default

(1 row affected, return status = 0)
1> drop index TABLE#DATA#DEALIRD_DBF.WHATEVER
2> go

此后无限期挂起。

从另一个会话中，我查看正在运行的内容：

我已经给了这个查询一整天的时间，而我只是为了确保它不会结束而只是在那里工作。

请注意，我无法使用新表重现它：

1> create table OMX(SOMETHING NUMERIC(2,2))
2> go
1> sp_helpindex OMX
2> go
Object does not have any indexes.
(return status = 1)
1> drop index OMX.WHATEVER
2> go
Msg 3701, Level 11, State 3
Server 'MX1530VM', Line 1
Cannot drop the index 'OMX.WHATEVER', because it doesn't exist in the system catalogs.

有谁知道如何继续我的分析？我检查了sysindexes但没有找到它的条目。我更新了桌面上的所有统计数据，但这没有帮助。

非常感谢！

您的会话（spid 270）处于“锁定睡眠”状态。这意味着它被另一个会话阻止了。您需要找出导致阻塞的项目被锁定，阻塞会话是什么以及它正在做什么以及它为什么不释放其锁定。它看起来像spid 6953导致阻塞。以“sp_lock @ verbose = 1”开头，查看哪个锁导致阻塞。
