1.模擬設備文件損壞
[root@sybaseHost sybase]# mv sysproc.dat sysproc1.dat重啓數據庫,sybsystemprocs爲可疑狀態
2.刪除數據庫
1> drop database sybsystemprocs
2> go
Msg 840, Level 17, State 2:
Server 'ASE12_5_4', Line 1:
Device 'sysprocdev' (with physical name '/opt/sybase/sysproc.dat', and virtual device number 1) has not been correctly activated
at startup time. Please contact a user with System Administrator (SA) role.
失敗，則通過手動刪除sysdatabase和sysusages記錄，並重啓數據庫(需要sp_configure 'allow update',1)
1> delete from sysusages where dbid=db_id('sybsystemprocs')
2> go
(1 row affected)
1> delete from sysdatabases where name='sybsystemprocs'
2> go
(1 row affected)
1> shutdown with nowait
2> go
3.刪除設備，重建設備和數據庫
1> sp_dropdevice 'sysprocdev'
2> go

4.通過installmaster創建存儲過程
[root@sybaseHost scripts]# isql -Usa -P -SASE12_5_4 -i /opt/sybase/ASE-12_5/scripts/installmaster
5.驗證
1> sp_helpdb
2> go
name db_size owner dbid created status

6.插曲
執行installmaster腳本的時候，master庫出現日誌溢出，通過disk resize調整設備大小，解決
