Public network accesses internal network Oracle database

The Oracle database is installed on the intranet host, which can only be accessed in the local area network. How can the local Oracle database be accessed from the public network?

This article describes the specific steps to implement using holer.

1. Preparation 1.1 install Java 1.7 and above

Execute the command java-version to check that Java is installed and configured correctly.

1.2 install and start the Oracle database

The default installed Oracle database port is 1521.

two。 Implement step 2.1 download and extract the holer package

Holer package: holer-client.zip

2.2 modify the holer configuration file

Apply for your own holer access key on Holer's official website or use access key information publicly available in the open source community.

For example, the holer information you applied for is as follows. Here we take the holer information as an example:

-Holer Client: holerdemo@gmail.comAccess Key: 8866daebe02846t88s166733595fff5d-Internet Address: holer.org:65014Local Address: 127.0.0.1 -

Modify the configuration file: holer-client/conf/holer.conf

The configuration item is updated to: HOLER_ACCESS_KEY=8866daebe02846t88s166733595fff5d

2.3 start the holer service

Enter the directory: holer-client/bin

Windows system platform:

Double-click startup.bat or open the CMD console and go to the directory to execute the command: startup.bat

Linux system platform:

Execute command: sh startup.sh

2.4 access the mapped public network address

Enter on the database client

Hostname: holer.org port number: 65014

This allows you to access the local Oracle database from the public network.

2.5 question consultation and help

If you encounter problems in the process of using holer, you can first check the holer log file, log path: holer-client/logs, so that it is easy to find out the specific cause of the problem.

For more examples of using holer, please refer to the technical materials related to holer.
