如何启动sybase数据库?

/////sdb1/sybase/ASE-12_5/install在这个路径下启动sybase.

如何查看sybase数据库连接的端口?
用syase用户登录:
[TA_SYBASE][/home/bta]su - sybase
Password:
[sybase@yudj ~]$  
[sybase@yudj ~]$ pwd
/sdb1/sybase
[sybase@yudj ~]$ ls 
ASE-12_5          OCS-12_5   SYBASE.csh  _jvm      data        jConnect-5_5  media.inf   sybcent41
ASEP              ODBC-12_5  SYBASE.env  charsets  installed   jConnect-6_0  setup       uninstall
HSFSS_SYBASE.cfg  RPL-12_5   SYBASE.sh   collate   interf.old  locales       shared-1_0  vpd.properties
JS-12_5           SQLRemote  SYSAM-1_0   config    interfaces  log.txt       sybase
看到interfaces这个文件名:
[sybase@yudj ~]$ vi interfaces
HSFSS_SYBASE
        master tcp ether 192.168.236.128 61001
        query tcp ether 192.168.236.128 61001

HSFSS_SYBASE_BS
        master tcp ether yudj 61002
        query tcp ether yudj 61002

HSFSS_SYBASE下面的就是看到主机的ip地址和数据库连接的端口。

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

如果主机的ip地址发生了变化,需要修改两个文件。
1.就是上面的interfaces文件中的ip地址。
2。用root用户修改/etc/hosts文件。将hosts文件中的ip地址改成目前新的主机地址。
[TA_SYBASE][/home/bta]su - root
