ASE中的命令行实用工具isql的几个参数的使用方法

在Sybase ASE中isql是个小巧而灵活的命令行实用工具。本人非常喜欢用这个工具，无论备份恢复、创建大到数据库小到表索引、配置参数、查看数据库的监控信息、分析dbcc的命令结果等等我都喜欢用isql来实现。有些用图形界面工具能够实现的功能，我都揣摩如何用命令来实现的，因为在ASE中所有用图形界面能够实现的功能操作都是可以用命令来完成的（当然图形工具还不能实现的地方太多）。我几乎不用sybase central，感觉这个工具既难用还低级简单。

下面介绍isql工具的使用方法。

呵呵，一些简单的命令参数我就不在这赘述了。我想每个sybase DBA对isql应该再熟悉不过了。今天我仅仅介绍几个本人自认为不太常用但是又比较实用的命令参数。

首先，查看一下isql这个工具都有哪些参数。

可能大家都知道在windows下用程序文件名称后面加空格再加上/? 来查看命令帮助。但是，对isql不能这么用。需要输入isql --help，如下图显示结果（有省略）

C:\Documents and Settings\Administrator>isql --help
usage: isql [option1] [option2] ... where [options] are ...
-b                   Disables the display of the table headers output.
-e                   Echoes input.
-F                   Enables the FIPS flagger.
-p                   Prints performance statistics.
-n                   Removes numbering and the prompt symbol when used with -e.
-v                   Prints the version number and copyright message.
-W                   Turn off extended password encryption on connection retries.
-X                   Initiates the login connection to the server with client-side
                       password encryption.
-Y                   Tells the Adaptive Server to use chained transactions.
-Q                   Enables the HAFAILOVER property.

如果输入 isql --h ，则返回简化版的命令参数。

C:\Documents and Settings\Administrator>isql --h
Syntax Error in '--h'.
usage: isql [-b] [-e] [-F] [-p] [-n] [-v] [-W] [-X] [-Y] [-Q]
        [-a display_charset] [-A packet_size] [-c cmdend] [-D database]
        [-E editor] [-h header] [-H hostname] [-i inputfile]
        [-I interfaces_file] [-J client_charset] [-K keytab_file]
        [-l login_timeout] [-m errorlevel] [-M labelname labelvalue]
        [-o outputfile] [-P password] [-R remote_server_principal]
        [-s col_separator] [-S server_name] [-t timeout] [-U username]
        [-V [security_options]] [-w column_width] [-y sybase directory]
        [-z localename] [-Z security_mechanism] [-x trusted.txt_file]
        [--retserverror] [--conceal [wildcard]] [--help]

今天仅介绍 -b, -e, -n,-E,-s,-w这六个参数的使用情况。

(1) 对于-b，命令参数的解释为：Disables the display of the table headers output。也就是不显示表的标题行。

如下面代码所示：

C:\Documents and Settings\Administrator>isql -Usa -Stest -b -Dandkylee
Password:
1> select * from testa
2> go
           1 aaaaaa
           2 bbbbbb
           3 ccccccc
(3 rows affected)

(2) 对于参数-e 和 -n ，-n要依附于-e来使用。

-e 表示Echoes input，也就是回显sql语句。

-n 表示Removes numbering and the prompt symbol when used with -e，也就是不显示sql语句前面的行号。

-e的用法如下：

C:\Documents and Settings\Administrator>isql -Usa -Stest -e -Dandkylee
Password:
1> select db_name()
2> go
1> select db_name()
------------------------------
andkylee
(1 row affected)
1> select * from testa
2> go
1> select * from testa
id          name
----------- ------------------------------
           1 aaaaaa
           2 bbbbbb
           3 ccccccc
(3 rows affected)

-e 和 -n 的联合用法如下：

C:\Documents and Settings\Administrator>isql -Usa -Stest -e -n -Dandkylee
Password:
select db_name()
go
select db_name()
------------------------------
andkylee
(1 row affected)
select * from testa
go
select * from testa
id          name
----------- ------------------------------
           1 aaaaaa
           2 bbbbbb
           3 ccccccc
(3 rows affected)

这时候你可能在怀疑了，上面我都输入了sql语句，我还要在返回结果中回显刚才输入的sql语句干什么？

的确，这个地方不是-e的应用场景。如果你用isql执行一个sql文件，并想把返回的结果保存到一个文件中，那么这个时候-e就有用处了。isql会在每个sql语句的执行结果前面加上相应的sql语句，这样看起来就很方便了。

简单举个例子：

假设有d:\test_isql.txt，里面的内容为：

select db_name()
go
select * from testa
go

我执行如下的命令参数：isql -Usa -P -Stest -Dandkylee -e -id:\test_isql.txt -od:\test_isql_result.txt

查看d:\test_isql_result.txt的文件内容为：

1> select db_name()

------------------------------
andkylee
(1 row affected)
1> select * from testa
id          name
----------- ------------------------------
           1 aaaaaa
           2 bbbbbb
           3 ccccccc
(3 rows affected)

对每个语句的执行结果一目了然，非常直观。

(3) -E 参数的使用

-E editor的意思是：Specifies an editor other than the default editor vi，也就是你可以指定一个文本编辑器用来在isql会话过程中编辑sql语句。这一点和sqlplusw中的ed命令是一模一样的。

多说一点，通过other than the default editor vi字面意思就可以看出，windows下的isql和unix下的isql有点不同。unix的isql下默认就可以使用vi进行编辑sql语句，但是 windows上的isql必须手动指定文本编辑器才能够使用这个功能。

C:\Documents and Settings\Administrator>isql -Usa -Stest -Enotepad -Dandkylee
Password:
1> notepad
[sh:notepad D:\PROGRA~1\ADMINI~1\LOCALS~1\Temp\cti9CE.tmp]
1> select db_name()
2> go
3> reset
1> notepad
[sh:notepad D:\PROGRA~1\ADMINI~1\LOCALS~1\Temp\cti9CE.tmp]
1> select db_name()
2> go
------------------------------
andkylee
(1 row affected)

使用方法是在isql的连接参数中加上-Enotepad（或者其它的文本编辑器，如notepad2，editlus都行，只要在win+R中能够成功执行的都可以！）

然后在提示符下输入notepad加上回车，就会弹出一个记事本让你进行编辑sql语句。这样是不是很方便，尤其在执行很长的sql语句的时候。哪怕输错一点点都要reset再重新输入一遍。这样就可以在文本编辑器中编辑好了再去执行了。（呵呵，可能你会说？不能在记事本中编辑好了直接复制粘贴到isql下执行吗？当然可以! ）

另外需着重注意一点，在文本编辑器中编辑的sql语句不能带有go，大家可以在我上面的演示代码中看出这一点。这个苛刻的要求就限制了我们不能在文本编辑器中输入多个sql语句命令。只能一个一个得来。

(4) 再来介绍今天的最后两个参数 -s -w, 我也是最近才开始使用这个参数-s的。感觉挺好。

-s col_separator的意思是：Resets the column separator character, which is blank by default，也就是说，你可以重新指定新的列分割符来替代默认的空格分隔符。

-w column_width 的意思是：Sets the screen width for output，也就是说，你可以指定屏幕的显示宽度（是像素还是字节，我没搞清楚）。

我把这两个参数放在一起使用，感觉效果很不错。请看下面的显示结果：

C:\Documents and Settings\Administrator>isql -Usa -Stest -Enotepad -s"|" -w5000
Password:
1> use andkylee
2> go
1> select * from test
2> go

1>

在这里我把列分割符替换成了|，显示出来的效果如上。是不是有点类似mysql的显示效果？我把屏幕的宽度设置成了-w5000。同时需要注意的是：你也需要把cmd的屏幕宽度设置大些。在命令提示符cmd 的属性里选择布局，调整屏幕缓冲区里面的宽度。这样就会显示类似上面的效果了。

执行一个字段多点的表，看看效果吧！

1> select * from sysobjects
2> where id< 20

（你要是发现比|还好的列分割符号，麻烦告诉我一下。谢谢！）

(5) 最后，介绍一个对于显示结果非常实用的存储过程sp_autoformat.

我也是在浏览一些系统存错过程源代码的时候发现的这个过程。这个是sybase 未公开的系统过程，用来格式化输出结果。如果想看这个过程的语法，请到sybsystemprocs里面查找。

看个效果吧！

(6) 补充，参数-p，显示性能统计信息.

参数-p：Prints performance statistics，与之对应的是会话级别的set statistics time on 。这两个方法都能够显示出统计信息，但是，会话级别的set statistics time on比参数-p的显示结果更详细些。

示例如下：

利用参数-p来显示简要统计信息：

C:\Documents and Settings\Administrator>isql -Usa -P -p
1> select count(*) from sysobjects
2> go
-----------
160
(1 row affected)
Execution Time (ms.): 0 Clock Time (ms.): 0

在每个SQL语句的最后显示执行时间和耗用时间。

会话级别的选项set statistics time on 显示比较详细的统计时间:

C:\Documents and Settings\Administrator>isql -Usa -P
1>
2> set statistics time on
3> go
Execution Time 0.
Adaptive Server cpu time: 0 ms. Adaptive Server elapsed time: 0 ms.
1> select count(*) from sysobjects
2> go
Parse and Compile Time 0.
Adaptive Server cpu time: 0 ms.
-----------
160
Execution Time 0.
Adaptive Server cpu time: 0 ms. Adaptive Server elapsed time: 0 ms.
(1 row affected)
1>

由上可以看出，会话级别选项set statistics time on会显示解析和编译时间、SQL执行时间、以及总计的执行时间、耗用时间。

啰啰嗦嗦就介绍这么多吧！

ASE v15中的应用程序跟踪tracefile特性

Sybase 在ASE v15.0.2 中新增了“应用程序”跟踪这个特性。

您可以利用“应用程序”跟踪功能收集一个正在运行中的客户会话的有用诊断信息，包括：执行查询、IO 消耗等；并且ASE 会自动把收集到的跟踪信息写到一个文本文件中。可以很方便得用这个特性来诊断一些系统性能瓶颈。

您只需要知道想要跟踪的会话的SPID(Server Process ID) 就可以对那个会话进行跟踪监控。应用系统的用户只需要被授予“set tracing ”权限就可以利用“应用程序”跟踪对自己的会话信息进行跟踪。

执行“应用程序”跟踪需要具有 set tracing 的权限。主要有两类用户：第一：具有sa或者sso角色的用户（默认具有set tracing权限）；第二:被赋予了set tracing 执行权限的用户。下面会分别予以介绍。

（1）具有管理员特权的用户（属于 sa 或者 sso 角色）

对其他用户连接会话启用“应用程序”跟踪，执行：

set tracefile "<file-path>" for <spid>

关闭刚才打开的针对其他用户连接会话的跟踪，需要执行：

set tracefile off for <spid>

备注：
(1) 针对某个用户会话启用跟踪时，需要知道它的SPID 并填写跟踪结果文件保存的路径。如果没有指定跟踪结果文件保存的路径，那么ASE 会自动保存到$SYBASE 目录下。
(2) 在一个会话中，只能有一个set tracefile 为启用状态；并且，某一个SPID 不能被多个会话同时跟踪。
(3) 当被跟踪的会话自己退出，或者跟踪被手动关闭时，ASE 会生成跟踪结果文件。
(4) 在“应用程序”跟踪的过程中，如果跟踪结果文件所在的磁盘空间被耗尽，那么ASE 会自动保存跟踪文件并结束本次“应用程序”跟踪。
(5) 用sp_helpapptrace 存储过程来查看当前正在执行中的所有应用程序跟踪信息。

（2）被赋予“set tracing” 权限的应用程序用户

对自己的会话启用跟踪，执行：

set tracefile "<file-path>"

结束对自己的会话上的跟踪，使用：

set tracefile off

备注： 不能使用sp_helpapptrace过程来查看正在被跟踪的会话。

（3 ）哪些信息可被用来跟踪？

在“应用程序”跟踪中可以追踪以下的set option 命令。

set show_sqltext <on/off>
set showplan <on/off>
set statistics io <on/off>
set statistics time <on/off>
set statistics plancost <on/off>

set option 的子命令也可被用来跟踪。

set option show_lop <normal/brief/long/on/off>                        ---显示使用的逻辑操作数量
set option show_managers <normal/brief/long/on/off>               --- 显示使用的数据结构管理器的数量
set option show_log_props <normal/brief/long/on/off> --- 显示所用的逻辑属性
set option show_parallel <normal/brief/long/on/off>                  --- 显示并行查询优化器信息
set option show_histograms <normal/brief/long/on/off>             --- 显示直方图统计信息处理过程
set option show_abstract_plan <normal/brief/long/on/off> --- 显示虚拟查询计划具体信息
set option show_search_engine <normal/brief/long/on/off>    --- 显示搜索引擎的详细信息
set option show_counters <normal/brief/long/on/off>             --- 显示优化器找到的计划的数量
set option show_best_plan <normal/brief/long/on/off> --- 显示最优计划信息
set option show_code_gen <normal/brief/long/on/off> --- 显示代码产生器的信息
set option show_pio_costing <normal/brief/long/on/off>            --- 显示估计的物理IO数
set option show_lio_costing <normal/brief/long/on/off>             --- 显示估计的逻辑IO数
set option show_elimination <normal/brief/long/on/off>           --- 显示分区消除信息

（4）例子（使用具有sa 和sso 角色的用户）

在一个会话中执行如下的命令：

set tracefile "c:/tmp/trace-spid-16.txt" for 16
set show_sqltext on
set showplan on
go
sp_helpapptrace
go

traced_spid tracer_spid trace_file

----------- ----------- ----------------------------

16 19 c:/tmp/ase-trace-spid-16.txt

(1 row affected)

(return status = 0)

上面的输出结果表明该会话的spid为16。
在另外一个会话中，在被监控的用户会话spid=16中执行sp_helpdb过程。

set tracefile off for 16
go
sp_helpapptrace
go

traced_spid tracer_spid trace_file

----------- ----------- ----------

(0 rows affected)

(return status = 0)

跟踪结果信息如下：

ASE12.x以及15.x中的保留关键字

在ASE中为对象命名的时候，要避免使用系统保留关键字，以防止带来不必要的麻烦。如果是对象名称必须使用系统的自留字，请用 quoted_identifer将该名称引起来。在ASE15.x中可以使用中括号[]来强制使用自留字作为对象名称。（这点功能和sqlserver 相似！）

演示一下在ASE15.x中使用中括号引起来保留字作为列名来创建一张表。

在12.x中不支持使用中括号来限定的方法。

回到正题，ASE的所有保留关键字有哪些呢？

可以通过查询系统表来得到结果。在spt_values表中type为W表示系统保留字。

执行select number,name from spt_values where type='W'这条语句可以得到所有的系统自留关键字。

关于保留字，对应着有一个系统存储过程sp_checkreswords可以用来查看系统内所有使用保留字作为对象名称的对象。

sp_checkreswords语法为:

sp_checkreswords - Detects and displays identifiers that are Transact-SQL
         reserved words. Checks server names, device names, database
         names, segment names, user-defined datatypes, object names,
         column names, user names, login names, and remote login names.
   sp_checkreswords [user_name_param]

之前我用create table testa ([create] int ,[alter] int)创建了一张表。在这张表所在的数据库内部执行sp_checkreswords过程，

系统报告出来了create alter 这两个列名在用关键字。

如何配置监控表MonTables来实现ASE的监控功能

Sybase ASE自12.5.0.3以来引入了一组监控表，称为：MonTables后者MDA tables。可以利用MDA表实现对sybase ASE的监控和诊断。监控表里面存储着对于ASE状态的统计、汇总信息的快照snapshot。我们可以像查询其他系统表（比如sysobjects、 sysindexes、syscolumns等）一样来查询这些监控表MonTables。

在12.x版本中MDA表默认是没有安装的，需要我们手动进行安装。在ASE15.x中新建数据库服务器的时候就默认装上了。

下面开始详细得介绍安装以及配置MDA的过程。

(1) 检查参数:enable cis是否启用？如果没有启用，打开该参数

sp_configure "enable cis"
go
Parameter Name Default Memory Used Config Value Run Value Unit Type
------------------------------ ----------- ----------- ------------ ------------ -------------------- ----------
enable cis 1 0 1 1 switch static
(1 row affected)

(2) 查看sysservers系统表中是否有loopback这一条记录，如果没有，手动添加一个指向自己的远程服务器

(注：在ASE12.5.4以及之后的版本中在创建数据库服务器的时候默认会添加一个loopback服务器。)

use master
go
sp_helpserver

exec loopback...sp_who  -- note: 3 dots!
go

(3) 安装MDA系统表

在unix的shell下执行：isql -Usa -Pyourpassword -Syourservername -i$SYBASE/$SYBASE_ASE/scripts/installmontables -o$SYBASE/$SYBASE_ASE/scripts/instmontables_log.txt

在windows的命令行下执行：isql -Usa -Pyourpassword -Syourservername -i％SYBASE％\％SYBASE_ASE%\scripts\installmontables -o％SYBASE％\％SYBASE_ASE%\scripts\instmontables_log.txt

（注：ASE15.x中不需要再安装mda表）

(4) 给需要有监控权限的登录赋予mon_role角色

use master
go
grant role mon_role to sa
go

use master
go
grant role mon_role to sa
go

(5) 检查测试基本的MDA配置信息

1> select * from master..monState
2> go
LockWaitThreshold LockWaits DaysRunning CheckPoints NumDeadlocks DiagnosticDumps Connections MaxRecovery StartDate CountersCleared
----------------- ----------- ----------- ----------- ------------ --------------- ----------- ----------- -------------------------- --------------------------
5 0 0 0 0 0 9 5 Apr 24 2010 1:34PM Apr 24 2010 1:34PM
(1 row affected)
1>

(6) 启用所有的监控配置参数

sp_configure "sql text pipe active",1
go
sp_configure "sql text pipe max messages",2000
go
sp_configure "plan text pipe active",1
go
sp_configure "plan text pipe max messages",1000
go
sp_configure "statement pipe active",1
go
sp_configure "statement pipe max messages",5000
go
sp_configure "errorlog pipe active",1
go
sp_configure "errorlog pipe max messages",1000
go
sp_configure "deadlock pipe active",1
go
sp_configure "deadlock pipe max messages",1000
go
sp_configure "wait event timing",1
go
sp_configure "process wait events",1
go
sp_configure "object lockwait timing",1
go
sp_configure "SQL batch capture",1
go
sp_configure "statement statistics active",1
go
sp_configure "per object statistics active",1
go
sp_configure "max SQL text monitored",256
go

其中参数：max SQL text monitored需要重启ASE服务器后才能生效。

(7) 重启ASE后，就可以通过查询monTables来了解ASE的监控信息了。比如：查看当前会话执行的sql语句。

1> sp_autoformat "monProcessSQLText"
2> go
SPID KPID    ServerUserID BatchID LineNumber SequenceInLine SQLText
---- ------- ------------ ------- ---------- -------------- ----------------------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------------------------------------------------------------------------
   31 2228258            1      35          1              1 SELECT SPID=right(space(80)+isnull(convert(varchar(80),SPID),'NULL'),4), KPID=right(space(80)+isnull
(convert(varchar(80),KPID),'NULL'),7), ServerUserID=right(space(80)+isnull(convert(varchar(80),ServerUserID),'NULL'),12), BatchID=right(space(80)+isnull
   31 2228258            1      35          1              2 (convert(varchar(80),BatchID),'NULL'),7), LineNumber=right(space(80)+isnull(convert(varchar(80),Line
Number),'NULL'),10), SequenceInLine=right(space(80)+isnull(convert(varchar(80),SequenceInLine),'NULL'),14), SQLText=SUBSTRING(convert(varchar(255),SQLTe
   31 2228258            1      35          1              3 xt),1,252) FROM monProcessSQLText
(3 rows affected)
(return status = 0)

备注：在ASE12.5.3及后续的版本中的某些罕见的情况下，配置参数"per object statistics active"会导致时间片的错误。这个bug已在ASE15.x中得到了修正。

另外，ASE的MDA监控功能对系统的整体性能是有不小的影响的，据说要损耗20%多的ASE系能。所以，不建议在生产环境上配置MDA监控表；如果启用了监控表，也一定要在不使用监控功能的时候及时关闭监控参数。执行：

sp_configure "enable monitoring",1
go

关于MDA监控表的使用，后面会有博文继续介绍...

如何查看ASE的非缺省配置参数

在Sybase ASE中查看或者修改配置参数有多种方法，比如：利用系统存储过程sp_configure；Sybase Central；Embarcadero DBArtisan等。

我比较喜欢用系统过程sp_configure来修改和查看参数。不管用那种方式，ASE的配置参数信息都是存储在两张系统表：sysconfigures和syscurconfigs上的。其中，表sysconfigures存储所有参数已生效 的详细信息；表syscurconfigs存储所有参数的当前配置信息。

另外，Sybase ASE各个版本中都会备份曾经修改过的配置参数文件。在$SYBASE目录下servername .cfg是系统的配置参数文件，每次修改系统的参数内容时，ASE都会为servername .cfg做一次备份，备份文件名称用servername 加上依次递增的数字。servername .cfg中每个参数值后面的DEFAULT表示该参数没有被改变，仍然使用默认值。我们可以利用这些配置备份文件servername .001,servername .002 ... servername .040 等，来追踪参数的修改过程。如果某个参数修改后对性能反而没有提升，那么我们就可以利用之前备份的参数文件来恢复到修改之前的参数值。

参数文件比较重要的一点功能是：在master系统库崩溃的时候，可以利用cfg或者顺序参数备份文件来恢复之前的ASE的配置信息。

说了这么多，现在回到标题上的主题。如何知道ASE中哪些参数被修改过了呢？或者说：如何查看哪些参数使用了非缺省呢？

我想起来两种方法：

第一种：查看配置文件servername .cfg的所有参数，并找出取值不等于DEFAULT的所有参数。

第二种：利用sp_configure存储过程。

可能还有别的办法，比如用Sybase Central或者其它的第三方工具。我没有在这些工具上寻找查看的方法，您要是知道也可以共享一下方法。

先来看看系统存储过程sp_configure的参数内容。我利用联机的帮助信息来查看sp_configure的参数，详细的使用方法请查看sybase官方文档中的存储过程这一本。

1> sp_syntax "sp_configure"
2> go
Syntax Help
------------------------------------------------------------------------------
System Procedure
sp_configure - Displays or changes configuration parameters.
   sp_configure [configname [, configvalue] | group_name
      | non_unique_parameter_fragment]
      ["p|P|k|K|m|M|g|G"]]
      Or,
      sp_configure "configuration file", 0, {"write" | "read"
      | "verify" | "restore" } "file_name"
(return status = 0)

（sybase ASE为15.0.3）

查看非缺省值参数的方法为：

1> sp_configure "display"
2> go

呵呵，这个方法的确很方便啊。

最后补充一点，sp_configure过程的源代码有1400多行，可见这个过程要实现的功能还是挺多的。

通过查看该过程的源代码，找到实现sp_configure "display"这个功能的sql语句为：

select Parameter_Name = convert(char(30), name),
Default_Value = convert(varchar(11), defvalue),
Memory_Used = convert(varchar(11), c.comment),
Config_Value = isnull(b.value2, convert(char(32), b.value)),
Run_Value = isnull(c.value2, convert(char(32), c.value)),
Unit = convert(char(20), c.unit),
Type_ = convert(char(10), c.type)
from master.dbo.sysconfigures b,
     master.dbo.syscurconfigs c
where
      b.config = c.config
and (c.defvalue != isnull(b.value2, convert(char(32), b.value))
      or
      c.defvalue != isnull(c.value2, convert(char(32), c.value)))
and c.config != 114 /* Exclude option 'configuration file' */
and c.type != "read-only"
and display_level <= 10 --@user_displaylevel
order by Parameter_Name
go

查询出来的结果是一样的。利用这一堆sql语句查询出来的结果可以用作进一步的分析。

就介绍到这里吧!

一例Vmware Server版本不一致导致的问题

在新的电脑上安装完Vmware Server2.0.2后，导入以前的虚拟机文件。在左边的虚拟机列表中选中虚拟机后，右边的窗口空白一片，无法查看虚拟机的配置信息也无法启动虚拟机。

在系统日志看，看到如下内容：

然后到目录：C:\Documents and Settings\All Users\Application Data\VMware\VMware Server下查看虚拟机的日志信息。依次查看hostd-0.log到hostd-9.log日志文件的内容。

发现如下比较重要的信息：

在网上寻找了很久，这篇博文解决VMWare Server 2.0 出现 Cannot Connect to VMX的问题的方法也不奏效。而且，vmware社区http://communities.vmware.com/index.jspa的很多帖子也没有给出有效的方法。这个Cannot connect to VMX问题也是个比较棘手的问题。

解决方法：原来我犯了一个低级的错误。曾经下载了vmware server 1.0.6 和 vmware server 2.0.2这2个版本的安装程序。因为以前的虚拟机环境不存在了，在新的电脑上安装的时候，就选择了vmware server 2.0.2。出现了上面的问题，曾经还重装了两次。最后看了一篇自己曾经写过的文档《在VMServer1.0.6中配置SQL Server 2005故障转移群集》，才意识到自己选错vmware的版本了。多么低级的一个错误啊，白白折腾了一天多的时间。

曾经还出现过如下的无法登录的问题：The server was unable to process your log in request.Please check with your server administrator.

解决方法：设置使得登录用户对虚拟机文件所在的目录拥有权限。

Sybase15.0.3跨平台恢复过程

演示一次sybase ASE15.0.3跨平台备份恢复的过程。

源数据库版本为：

1> select @@version
2> go
-----------------------------------------------------------------------------------------
------------------------------------------------------------------------------------------
----------------------------------------------------------------------------
Adaptive Server Enterprise/15.0.3/EBF 16738 ESD#2/P/NT (IX86)/Windows 2003/ase1
503/2708/32-bit/OPT/Mon Jul 27 20:19:56 2009

目的数据库版本为：

1> select @@version
2> go
-----------------------------------------------------------------------------------------
------------------------------------------------------------------------------------------
----------------------------------------------------------------------------
Adaptive Server Enterprise/15.0.3/EBF 16548 ESD#1/P/Sun_svr4/OS 5.8/ase1503/268
0/64-bit/FBO/Thu Mar 5 09:39:28 2009

跨平台恢复的详细过程如下：

(1). 检查欲备份的数据库testdb的完整性，利用checkdb和checkalloc

1> dbcc traceon(3604)
2> go
1> dbcc checkdb(testdb)
2> go
1> dbcc checkalloc(testdb)
2> go

(2). 将数据库testdb设置为单用户模式

1> use master
2> go
1> sp_dboption testdb,"single",true
2> go

(3). 清空testdb的日志，并设置检查点

1> dump tran testdb with no_log
2> go
1> checkpoint
2> go

(4). 将属于数据库testdb的脏页写到磁盘上面去，并发出检查点命令。在发出sp_flushstats系统过程后要等待一段时间，保证数据库有足够的时间把页面信息刷新到磁盘上。

1> sp_flushstats
2> go
1> checkpoint
2> go

(5). 备份数据库testdb

1> dump database testdb to "d:\testdb-20100409.dmp"
2> go

(6). 利用ftp服务器将备份出来的testdb-20100409.dmp文件拷贝到solaris服务器上。

(7).用isql连接到目的数据库服务器上面，执行恢复命令

1> load database testdb from "/app/sybdata/testdb-20100409.dmp"
2> go

(8). 将目的数据库服务器中的testdb调整成在线。

1> online database testdb
2> go

(9). 进入testdb，执行sp_post_xpload系统存储过程来重建用户表的索引。

1> use testdb
2> go
1> sp_post_xpload
2> go

至此，跨平台备份恢复过程完成！

补充：以下为load database过程显示的所有的反馈信息。

sybase中给表增加和删除字段时内部处理过程分析

分析一下给表增加字段时sybase数据库的内部处理过程。

表原来的结构：

create table t(id int, col1 varchar(30))

向表中插入数据：

insert into t
select 1,'a'
go
insert into t
select 1,'a'
go
insert into t
select 2,'b'
go
insert into t
select 3,'c'
go

测试表t的object_id是：

1> select object_id('t')
2> go

-----------
608002166

利用dbcc log分析数据库的日志，可以看出上面的四条insert语句对应了四个单独的事务。因为sybase中默认是隐式提交的。

四条记录的页号和偏移分别是：

row1. pageno=801 offset=32

row2. pageno=801 offset=44

row3. pageno=801 offset=56

row4. pageno=801 offset=68

接着，向表中添加一个identity字段。

alter table t add col2 int identity not null
go

再利用dbcc log分析日志，我们可以看出在这四行数据上面发生了延迟更新（op=6,INSID在日志类型中是延迟更新的意思！）。

每行数据的页号和偏移变成了：

比较一下前后的各行的偏移量。我们发现：第一行没有移动，第二行向下移动了5（49-44）字节，第三行向下移动了10字节，第四行向下移动了15字节（83-68）。也就是说，每行增加了5个字节的数据。5个字节是因为：int类型占用4个字节再加一个字节的长度。

关于alter table add语法方面的

在向表添加列时是不能够添加not null 列的。错误如下所示：

1> alter table t add col4 char(30) not null
2> go
Msg 4997, Level 16, State 1:
Server 'SYB_NFJD_TEST', Line 1:
ALTER TABLE 't' failed. Default clause is required in order to add non-NULL
column 'col4'.
1> alter table t add col4 int not null
2> go
Msg 4997, Level 16, State 1:
Server 'SYB_NFJD_TEST', Line 1:
ALTER TABLE 't' failed. Default clause is required in order to add non-NULL
column 'col4'.
1>

1. 只能添加为空的字段。

2. 但是，本文前面的向表添加identity类型的int 非空字段却可以。alter table t add col2 int identity not null却可以。

3. 这似乎和SQL标准中的不太一致。

4. 分析page：801页面上的数据。发现最后添加的identity列居然是作为可变长字段进行存储的。字段col即使被定义为非空，但是物理存储上却是作为可变长存储的。因为是varchar类型。

注意： 后来我通过试验发现有一种例外情况。就是新增一个非空列的时候对这列指定默认值，就可以成功增加这列。

比如：alter table test add COLC char(1) default "0" not null

这条语句就能够成功执行！

删除表上的字段的时候报错：

1> alter table t drop col2
2> go
Msg 11052, Level 16, State 1:
Server 'SYB_NFJD_TEST', Line 1:
The 'select into' database option is not enabled for database 'testdb'. ALTER
TABLE with data copy cannot be done. Set the 'select into' database option and
re-run.
1>

报错的原因是表t所在的数据库testdb没有打开select into buklcopy选项。

打开testdb的select into/bulkcopy/pllsort 选项

1> use master
2> go
1> sp_dboption testdb,'select into',true
2> go
Database option 'select into/bulkcopy/pllsort' turned ON for database 'testdb'.
Running CHECKPOINT on database 'testdb' for option 'select
into/bulkcopy/pllsort' to take effect.
(return status = 0)

再次执行删除列的操作，可以执行成功！

1> use testdb
2> go
1> alter table t drop col2
2> go
(4 rows affected)

删除完col2之后，再次分析一下dbcc log的结果。

发现背后进行的操作有三步：

第一：删除表t在systabstats上的统计信息并重建；

第二：删除在系统表sysstatistics,sysobjects,syscolumns,sysindexes,syspartitions上对应记录的索引然后重建；

第三：更新在系统表sysstatistics,sysobjects,syscolumns,sysindexes,syspartitions上对应记录的信息。

删除表上的列的过程的日志信息，如下：

有兴趣的可以自己分析一下。

自己先补充一下。

如果数据库没有打开select into选项的时候，drop column都会报错误：

Msg 11052, Level 16, State 1: Server 'TEST', Line 1: The 'select into' database option is not enabled for database 'escourt5'. ALTER TABLE with data copy cannot be done. Set the 'select into' database option and re-run 。

注意：不能添加非空列（除了第一个identity列）。添加一列的时候，指定为非空并且有默认值的话，也报错：

1> alter table test add COLE char(1) default "0"

2> go

Msg 11052, Level 16, State 1: Server 'TEST', Line 1: The 'select into' database option is not enabled for database 'escourt5'. ALTER TABLE with data copy cannot be done. Set the 'select into' database option and re-run.

有空总结一下。为什么会进行data copy。
