主要原因可能有：

1、操作系统不被支持；

2、sybase环境变量不正确；

case 1：

在SUSE 10 x64 上安装了ASE 15.7 ESD#7的32位的客户端，使用isql连接的时候，报： Client password encryption fails（客户端密码加密失败）

通过查询sybase官方的版本与平台支持信息，

ID Product Prod
Version		 Prod
Word Size		 OS Version Status
1436 Adaptive Server Enterprise 15.0 64-bit SuSE SLES 10 (AMD64/EM64T) Certified
     
General Notes:    ASE15.7 release does NOT support SLES10. Due to recent changes in glibc, the environment variable LD_POINTER_GUARD should be set to 1 for ASE to function properly. This variable should be set before starting any ASE binary. Note that there is known bug with the configuration step of the ASE installer. Please use "srvbuild" or "srvbuildres" to configure devices. This bug will be fixed in a future release of ASE. ASE15.5 ESD5.2 can't install on SUSE10SP2 Work-round: Replace sylapi with 32bit and change to 32bit JRE. ASE 15.5 support SUSE10: kernel-smp-2.6.16.21-0.8 glibc-2.4-31.2 ASE CE 15.5 support SUSE10.1: kernel-smp-2.6.16.46-0.12 glibc-2.4-31.30 e2fsprogs-1.38-25.21 libaio-0.3.104-14.2 libgcc-3.3.3-43.41 libstdc++-3.3.3-44.41 compat-libstdc++-5.0.7-22.2
Minimum Product Level :    ASE 15.0.2 ESD#1
ASE15.5 GA to ASE15.5 ESD5.1
ASE15.7 release does NOT support SLES10.
Minimum Required OS Level :    ASE15.7 release does NOT support SLES10. ASE15.7 requires SLES 11.0 as minOS.

For ASE15.0.2 and higher to ASE15.5 ESD5.1:
SuSE 10

kernel-smp-2.6.16.21-0.8
glibc-2.4-31.2
glibc-devel-2.4-31.2

再查看ASE 15.7的最低支持平台，看到：

ID Product Prod
Version		 Prod
Word Size		 OS Version Status
2826 Adaptive Server Enterprise 15.0 64-bit SuSE SLES 11 (AMD64/EM64T) Certified
     
General Notes:    ASE15.7 is certified / released on SLES 11.0. ASE15.7 is certified on SuSE SLES 11 SP2 ASE15.7SP120 is certified on SuSE SLES 11 SP3 ASE155 ESD4 is certified on SuSE SLES 11 SP3 ase1503 esd3 is certified with SUSE11, but note following issue: issue 1: jvm file io will hit stacktrace workaround: During the creation of the PCA/JVM it is necessary to retrieve userid/password information from the network security services (nss) to allow the virtual machine to create a shared memory region. If the information is attempted to be retrieved from the network information service (nis) provider a SEGV will occur. To avoid this a different provider must be able to supply the information prior to attempting to retrieve the information via nis. For nss implementations specifying either 'compat' or 'files nis' retrieval order in the /etc/nsswitch.conf file the following alternatives may be used to avoid this problem: 1) Add the userid and password for the user starting the Adaptive Server to the local /etc/passwd and /etc/shadow files using either the adduser command or the graphical user interface for system administration tasks on the host where the server is to be run. This will allow the userid/password request to be satisfied by the local information without recourse to the nis call for this information. 2) If it is not possible or desirable to add the user information to the local files ensure that the name service cache daemon (nscd) is running on the host where the server will be run. The nscd maintains a cache of the userid and password information that is consulted prior to dispatching a request to the nis for this information. issue 2: all older versions than ase1503 esd3 can't work with SUSE11. ASE CE 15.5 has not certified with SUSE11 ASE15.5 has been certified with SUSE11 SP1

由上可以看到如果想在SUSE上安装ASE 15.7，需要操作系统至少是：SUSE Enterprise Linux Server 11以上。

在SLES 11 SP1上再次安装SDK ASE 15.7 ESD#7,isql能够正常登录ASE服务器。

 

另外一个case也是报Client password encryption fails.

在AIX 6.1平台上，syb64用户下安装ASE 15.7服务器端：Adaptive Server Enterprise/15.7.0/EBF 19625 SMP ONE-OFF/P/RS6000/AIX 6.1/ase157/2820/64-bit/FBO/Fri Oct 14 11:43:25 2011

sybase用户下安装ASE 15.7客户端：SDK ASE 157/P-EBF20747 ESD#7/DRV15.7.0.7

使用syb64用户执行： /syb64/OCS-15_0/bin/isql -Usa -P??? -Sservername能够正常登录，
使用syb64用户执行：/sybase/OCS-15_0/bin/isql -Usa -P??? Sservername就报Client password encryption fails

原因：

在syb64调用/sybase/OCS-15_0/bin/isql时，引用了syb64当前环境下的/syb64/ASE-15_0下的lib库文件，而/syb64/ASE-15_0下的lib文件版本要低于/sybase下的。

解决方法：

使用syb64加载用户sybase的SYBASE环境变量：

    重启了一下sybase服务器，就启动不起来了。

    ======================================================================

    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。
