3. 软件要求

操作系统版本Linux 5.0 以上。

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

[root@orcl2 ~]# cat /proc/version

Linux version 3.10.0-327.13.1.el7.x86_64 ([email protected]) (gcc version 4.8.3 20140911 (Red Hat 4.8.3-9) (GCC) ) #1 SMP Thu Mar 31 16:04:38 UTC 2016

[root@orcl2 ~]# cat /etc/redhat-release

CentOS Linux release 7.2.1511 (Core)

[root@orcl2 ~]#

 

4. 安装

4.1. 运行 runInstaller

 

 

4.2. Specify Installation Location

Oracle base: /oracle/app/oracle

Software location：/home/gateways

 

 

4.3. Available Product Components

 

4.4. Gateways for Microsoft SQL Server

 

4.5. Perform Prerequisite Checks

 

 

4.6. Summary

 

 

4.7. Install Product

 

 

4.8. Net CA(此步可先跳过)

 

 

 

4.9. Execute Configuration scripts

 

 

Last login: Fri Aug 19 16:07:21 2016 from 10.1.11.200

[root@orcl2 ~]# /home/gateways/root.sh

Performing root user operation.

 

The following environment variables are set as:

    ORACLE_OWNER= oracle

    ORACLE_HOME=  /home/gateways

 

Enter the full pathname of the local bin directory: [/usr/local/bin]:

The contents of "dbhome" have not changed. No need to overwrite.

The contents of "oraenv" have not changed. No need to overwrite.

The contents of "coraenv" have not changed. No need to overwrite.

 

Entries will be added to the /etc/oratab file as needed by

Database Configuration Assistant when a database is created

Finished running generic part of root script.

Now product-specific root actions will be performed.

[root@orcl2 ~]#

4.10. Finish

 

 

5. 配置网关初始化参数文件

For example, all of the following entries are valid:

HS_FDS_CONNECT_INFO=host_name/instance_name/database_name

HS_FDS_CONNECT_INFO=host_name//database_name

HS_FDS_CONNECT_INFO=host_name:port_name//database_name

HS_FDS_CONNECT_INFO=host_name/instance_name

HS_FDS_CONNECT_INFO=host_name 

 

5.1. 自定义初始化参数文件

[oracle@orcl2 /home/gateways/dg4msql/admin]$ll -a

HS_FDS_RECOVERY_ACCOUNT=RECOVER

HS_FDS_RECOVERY_PWD=RECOVER

 

[oracle@orcl2 /home/gateways/dg4msql/admin]$

5.2. 配置网关监听

[oracle@orcl2 /home/gateways/network/admin]$cat listener.ora

# listener.ora Network Configuration File: /home/gateways/network/admin/listener.ora

# Generated by Oracle configuration tools.

 

LSN_GATEWAYS =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = orcl2)(PORT = 1533))

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1533))

    )

  )

 

 

#add sid_list_lsn_gateways

SID_LIST_LSN_GATEWAYS=

   (SID_LIST=

      (SID_DESC=

         (SID_NAME=dg4msql)

         (ORACLE_HOME=/home/gateways)

         (PROGRAM=dg4msql)

      )

   )

[oracle@orcl2 /home/gateways/network/admin]$

 

5.3. 停止并重启网关监听

[oracle@orcl2 ~]$export TNS_ADMIN=/home/gateways/network/admin

[oracle@orcl2 ~]$echo $TNS_ADMIN

/home/gateways/network/admin

[oracle@orcl2 ~]$lsnrctl
