如何启动sybase数据库？
[TA_SYBASE][/home/bta]su - sybase //切换到sybase用户。

[sybase@yudj ~]$ pwd

//说明：sdb1为挂载虚拟机磁盘。
/////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

[root@yudj ~]# cd /etc
[root@yudj etc]# vi hosts
