首先，应检查Server的日志文件。不同版本缺省的日志文件如下（其中<server_name>为Sybase Server的名称：
UNIX:
11.0*: $SYBASE/install/errorlog
11.5* 或 11.9*: $SYBASE/install/<server_name>.log
12.0*: $SYBASE_ASE/install/<server_name>.log
NT:
11.0* 11.5* 或 11.9*: $SYBASE\install\errorlog
12.0*: $SYBASE\ASE-12_0\install\errorlog
CASE 1:
basis_dlock: file '/sybase/master.dat' already in use by a SQL Server
kernel kdconfig: unable to read primary master device
kernel kiconfig: read of config block failed
检查server是否已经启动( showserver, ps -u sybase 或NT service )
CASE 2:
dopen: open '/sybase/master.dat' failed, permission denied
kernel kdconfig: unable to read primary master device
kernel kiconfig: read of config block failed
检查master设备文件的所有者及权限
CASE 3:
ninit: All master network listeners have failed. Shutting down
检查network ip 及 port配置 ( netstat -a )
CASE 4:
kernel:kscsinit: connectivity library error. Operation: cs_ctx_alloc().
检查操作系统参数是否已经修改并重新启动操作系统 (参见安装手册)
若操作系统异常宕机，ASE未启动而$SYBASE/<server_name>.krg已经存在, 删除该文件
