 1、Firewall Exceptions for Oracle Database

For basic database operation and connectivity from remote clients, such as SQL*Plus, Oracle Call Interface (OCI), Open Database Connectivity (ODBC), Object Linking and Embedding database (OLE DB) applications, and so on, the following executables must be added to the Windows Firewall exception list:

• Oracle_home\bin\oracle.exe - Oracle Database executable

• Oracle_home\bin\tnslsnr.exe - Oracle Listener

If you use remote monitoring capabilities for your database, the following executables must be added to the Windows Firewall exception list:

• Oracle_home\bin\emagent.exe - Oracle Database Control

• Oracle_home\jdk\bin\java.exe - Java Virtual Machine (JVM) for Enterprise Manager Database Control

 2、Firewall Exceptions for Oracle Database Examples (or the Companion CD)

After installing the Oracle Database Companion CD, the following executables must be added to the Windows Firewall exception list:

• Oracle_home\opmn\bin\opmn.exe - Oracle Process Manager

• Oracle_home\jdk\bin\java.exe - JVM

3、 Firewall Exceptions for Oracle Gateways

If your Oracle database interacts with non-Oracle software through a gateway, then you must add the gateway executable to the Windows Firewall exception list. Table 5-1table lists the gateway executables used to access non-Oracle software.

Table 5-1 Oracle Executables Used to Access Non-Oracle Software

Executable Name	Description
omtsreco.exe	Oracle Services for Microsoft Transaction Server
dg4sybs.exe	Oracle Database Gateway for Sybase
dg4tera.exe	Oracle Database Gateway for Teradata
dg4msql.exe	Oracle Database Gateway for SQL Server
dg4db2.exe	Oracle Database Gateway for Distributed Relational Database Architecture (DRDA)
pg4arv.exe	Oracle Database Gateway for Advanced Program to Program Communication (APPC)
pg4t4ic.exe	Oracle Database Gateway for APPC
dg4mqs.exe	Oracle Database Gateway for WebSphere MQ
dg4mqc.exe	Oracle Database Gateway for WebSphere MQ
dg4odbc.exe	Oracle Database Gateway for ODBC

4、 Firewall Exceptions for Oracle Clusterware and Oracle ASM

If you installed the Oracle Grid Infrastructure software on the nodes in your cluster, then you can enable the Windows Firewall only after adding the following executables and ports to the Firewall exception list. The Firewall Exception list must be updated on each node.

• Grid_home\bin\gpnpd.exe - Grid Plug and Play daemon

• Grid_home\bin\oracle.exe - Oracle Automatic Storage Management (Oracle ASM) executable (if using Oracle ASM for storage)

• Grid_home\bin\racgvip.exe - Virtual Internet Protocol Configuration Assistant

• Grid_home\bin\evmd.exe - OracleEVMService

• Grid_home\bin\crsd.exe - OracleCRService

• Grid_home\bin\ocssd.exe - OracleCSService

• Grid_home\bin\octssd.exe - Cluster Time Synchronization Service daemon

• Grid_home\bin\mDNSResponder.exe - multicast-domain name system (DNS) Responder Daemon

• Grid_home\bin\gipcd.exe - Grid inter-process communication (IPC) daemon

• Grid_home\bin\gnsd.exe - Grid Naming Service (GNS) daemon

• Grid_home\bin\ohasd.exe - OracleOHService

• Grid_home\bin\TNSLSNR.EXE - single client access name (SCAN) listener and local listener for Oracle RAC database and Oracle ASM

• Grid_home\opmn\bin\ons.exe - Oracle Notification Service (ONS)

• Grid_home\jdk\jre\bin\java.exe - JVM

5 、Firewall Exceptions for Oracle RAC Database

For the Oracle RAC database, the executables that require exceptions are:

• Oracle_home\bin\oracle.exe - Oracle RAC database instance

• Oracle_home\bin\emagent.exe - Oracle Enterprise Manager agent

• Oracle_home\jdk\bin\java.exe - For the Oracle Enterprise Manager Database Console

In addition, the following ports should be added to the Windows Firewall exception list:

• Microsoft file sharing system management bus (SMB)

  • User Datagram Protocol (UDP) ports from 135 through 139

  • TCP ports from 135 through 139

• Direct-hosted SMB traffic without a network basic I/O system (NetBIOS)

  • port 445 (TCP and UPD)

6、 Firewall Exceptions for Oracle Cluster File System for Windows

If you use Oracle Cluster File System for Windows (OCFS for Windows) to store the Oracle Clusterware files, or Oracle RAC database files, then you must add the following exceptions to the Windows Firewall:

• Grid_home\cfs\Ocfsfindvol.exe - OCFS for Windows Volume Service

• %WINDOWS_HOME%\system32\drivers\Ocfs.sys - System file for OCFS (if using OCFS for Windows for Oracle Clusterware storage)

7 、Firewall Exceptions for Other Oracle Products

In addition to all the previously listed exceptions, if you use any of the Oracle software listed in, then you must create an exception for Windows Firewall for the associated executable.

Table 5-2 Other Oracle Software Products Requiring Windows Firewall Exceptions

Oracle Software Product	Executable Name
Data Guard Manager	dgmgrl.exe
Oracle Internet Directory lightweight directory access protocol (LDAP) Server	oidldapd.exe
External Procedural Calls	extproc.exe

Windows平台安裝的oracle 11gr1 rac需開啟防火牆什連接埠才可以不影響叢集的正常工作？

建議全開。
防火牆有可能會影響到rac的效能。
 
Oracle11g安裝好以後為何服務裡面只有四個Oracle項？

全部卸掉然後重裝比較好..
