In Oracle Net, the database server may also be a client.This is because tnsnames. ora can have a server description.That is, only the listener will always be a server.Instance: Listener = N: m(I) benefits of dual listeners:① Client Failover-cf② Client Server Load balancer-CLB(Ii) Notes:① Ensure port 1521 is available; otherwise, OEM will be unavailable and emca must be reconfigured② Static registration for non-standard ports is a good practice

Third generation, in addition to dynamic document generation and access, also provides web-based online transaction processing capabilities.

1. Unable to support background database
2. Unable to effectively update the site information in a timely manner
3. Can not achieve dynamic display effect

This is not allowed. Below we use the above learning request obje

Ii. related parameter settings
The following is an example of how to set relevant parameters:1. Environment Variable: oracle_sid = Rac1/2
2. initsid. ora:Db_name = ora92Service_names = ora92Instance_name = Rac1/2Global_names = falseDb_domain = ""
3. listener. ora:Sid_list_rac1 =(Sid_list =(Sid_desc =(Global_dbname = ora92)(ORACLE_HOME =/Oracle/oracle9/APP/Oracle/product/9.2.0)(SERVICE_NAME = ora92) (sid_name = Rac1)))
parameters are very complicated, but we do not use the actual usage of course October is the better.
Second, the related parameter setting
I'll give you an example of how to set the parameters:
1. Environment variable: ORACLE_SID=RAC1/2
2, Initsid.ora:
Db_name=ora92
Service_names = Ora92
Instance_name=rac1/2
Global_names=false
Db_domain= ""
3, Listener.ora:
SID_LIST_RAC1 =

In this way, the parameters are complicated, but we will not actually use them. of course, October is as simple as possible. II. related parameter settings I will illustrate the settings of related parameters below: 1. environment variable: ORACLE_SID = rac1/2. initsid. ora: db_name = ora92 service_names = o
