今天在测试sybase服务器上配置encryption加密功能，测试一下数据加密的新特性。
sp_configure "enable encrypted columns",1
go
之后errorlog中显示：

======================================================================
暂时忽略number of engines at startup 和 max online engines 这两个参数不一致的情况。因为我的本是双核cpu。
关于内存配置，我没有调整max memory,在.cfg文件中一致都是DEFAULT。现在启动的时候报内存39936不够用，需要41568bytes内存。说明sybase中的 encryption选项是需要消耗一定的内存的， 另外用加密这个选项不知道对性能的影响有多大。想想每次写入数据库设备的数据都要在内存中进行加密处理了之后才写入磁盘。这给处理器有增加了负担。对性能的影响待以后有时间体会一下。

很郁闷，对360很失望。上午在用360优化电脑的时候，平时我是不用什么优化大师或者什么兔子、360来倒腾电脑的。因为：我觉得也不知道软件具体删除了哪些文件，误删了文件就麻烦了。果不其然，360把我的服务信息给搞没了。
在用360软件管家中的开机加速后，我的一些服务不能自动启动了。
从其他sybase服务器上导出项目HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SYBSQL_TEST 的信息，用记事本打开，如下的信息：

请将红色的TEST替换为你的sybase服务器名称即servername。如果你是导出的12.5版本的注册表信息，请修改对应的Library值（红色标记）。 蓝色标记的ImagePath是十六进制的，请在注册表内修改，就是系统启动的程序的路径。
修改完之后，就可以启动sybase服务了。在服务中启动或者sc start sybsql_servername 都是可以的！
其它类似backup，monitor，xpserver，和主服务类似。不再赘述。
但是很郁闷，我的sql server database analysis agent服务不知道该如何添加注册表信息了。估计只能通过重新安装程序来解决了。
到注册表了查看，关于SYBBCK_TEST_BS ，SYBMON_TEST_MS ， SYBSQL_TEST ，SYBXPS_TEST_XP,以及 sql server database analysis agent 服务的信息全不见了。 360太可恨了，幸亏本人懂sybase的注册表配置信息，不然真的重装一遍sybase系统了。

将Sybase的字符集调整为支持简体中文的cp936字符集。
步骤如下：
(这里假设SYBASE的安装路径为c:\sybase)
1.c:\>cd \sybase\charsets\cp936
2.c:\sybase\charsets\cp936> charset -U用户名 -P密码 -S数据库服务器名称 binary.srt cp936
更改默认字符集为cp936
3.在SQL环境中
1>select name,id from syscharsets(会列出字符集对应的id号)
2>go
找到name为cp936对应的id(假设为171)
.1>sp_configure "default character set id",171
2>go
5.重启server两次
（注:第一次启动后，server会自动宕掉，需要第二次重启后才能使用）
启动之后，要清空日志。应该是sybase日志恢复时不会转换字符集吧，所以先前的日志没有作用了。要及时清除掉！
清空提交日志dump tran dbname with truncate_only
=====================================================================
SYBASE使用utf8字符集出现乱码问题的解决
于国际化的原因，现在使用sybase15.0.3字符集utf8作为默认字符集，现在客户端与服务端一致都配置成为 locale=default,us_english,utf8 ,发现使用客户端写入数据后，汉字全为乱码。在isql下用iso_1，cp850字符集连接上，查询已有数据汉字全为乱码。
解决的办法：
将客户端改为cp936，或者在isql连接的时候指定字符集为简体中文字符集cp936即-Jcp936。
问题解决！
ps：在isql查看客户端字符集为：select @@client_csname
查看服务器的默认排序顺序：sp_configure "default sortorder"
