How to Check Standby Database Hostname From Primary

Trying to connect to the standby database? It’s possible to do that, but first you must know how to connect to the primary. The hostname for the standby database must match the one on the primary. You can do this with a number of different methods. In the following article, we’ll discuss the different options available. In the meantime, try to connect to the standby database with a local TCP client.

Using a tnsping command, you can check whether your standby database is working correctly. First, you need to create a PFILE on the primary server, and then copy that file to the standby server. This file should be located in the $ORACLE_HOME/database directory. After copying the PFILE to the standby server, you need to run a tnsping query on the primary server to see which sessions are active on the standby database.

Once you have backed up your primary database, you need to check the hostname of the standby database. You can do this manually or by using a database tool. Depending on the setup, you can restore the cold backup to the DRS at the same path. The archive redo log files from the primary database will be copied to the standby database. Moreover, you should ensure that the hostname of the standby database is the same as that of the primary database.

After you have created a Dataguard environment, you need to configure the protection mode and select the standby database from the primary. Then, run a DBMS command that returns the unique name of the standby databases in the environment. After you have done this, you can click on OK. This is a great way to ensure that the standby databases are working properly. In addition, it also saves you a lot of time.

You can use a DMV utility to check the state of your standby database. You can also check the redo transport by examining the “Data Guard” property. It displays a list of errors that occurred during transport. It also displays a list of redo transport properties. It’s important to make sure that you have a database that is ONLINE before you try to connect to it from another system.

If the primary database is configured to turn on redo transport services, you can force redo transport services for the standby database. However, this will not affect the overall protection mode, as it will not prevent data loss. You must ensure that at least one of the standby databases is enabled in order to use redo transport. You can do this by following the steps described in Table 4-2. After completing these steps, you can start testing the protection mode of your standby database.

The standby database should be able to reach the primary by hostname. Its hostname must also match the primary. By default, the standby database instance is first on the hadr-target-list of the primary database. If the primary database goes offline, it will import redo log files from the primary database, but it will only read redo entries archived by ORACLE. You should then copy the backup image from the standby to the primary.
