Sybase - 刪除不存在的索引時掛起

Question

我正在運行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並面臨奇怪的問題。

當拖放不存在索引，我發現了一個無限期掛：

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 

它在這之後無限期地掛起。

從另一個會話，我檢查什麼的運行：

2> go 
SQL Text: drop index TABLE#DATA#DEALIRD_DBF.WHATEVER 

DBCC execution completed. If DBCC printed error messages, contact a user with System Administrator (SA) role. 

我考慮了查詢一整天，而我的工作是別的東西，只是爲了確保它不會結束，但它只是坐在那裏。

請注意，我不能用新表重現：

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. 

有誰知道我可以繼續我的分析？我檢查了sysindexes，但沒有找到它的條目。我更新了桌面上的所有統計數據，但這沒有幫助。

非常感謝！

您的會話（spid 270）處於'鎖定睡眠'狀態。這意味着它被另一個會話阻止。你需要找出哪些項目被鎖定導致阻塞，阻塞會話是什麼以及它在做什麼以及爲什麼它不釋放它的鎖定。它看起來像spid 6953導致阻塞。 以「sp_lock @ verbose = 1」開頭，查看哪個鎖正在導致阻塞。
