SolarWinds DPA的升级其实是一件非常简单的事情，这里介绍一下从DPA 9.1.95升级到 DPA 10.0.352版本的流程。为什么要升级呢？ DPA给用户发的邮件已经写的非常清楚了（如下所示），DPA 10.0这个版本已开始支持MySQL了，另外它解决了一些Bug，在性能上有所改进、提升。
Our records indicate that you might have Database Performance Analyzer (DPA) 9.0 installed and licensed. If you have upgraded all your DPA servers to a later version (v9.1, 9.2, or 10.0), please ignore this email.
While SolarWinds transitioned Confio customers to a new licensing model in August 2014, it delayed the enforcement of core licenses for Oracle, DB2 and Sybase until November 10, 2015. If you are using DPA 9.0 with core licenses for Oracle, DB2 or Sybase, you should upgrade all your DPA servers to the latest version available in the Customer Portal before November 10, 2015. This will ensure that DPA can be configured to monitor all the databases that are licensed.
What will happen if I don’t upgrade?
DPA will start technically enforcing licenses for Oracle, DB2 and Sybase on November 10, 2015. If you are under your license limit, DPA will continue to collect data from all licensed database instances. If you have exceeded your licensing limit, DPA will unlicense all registered databases and stop monitoring them, and you will have to select which databases you want to monitor up to your license limit.
How many licenses will I have once I upgrade to a later version?
- If you purchased Oracle, DB2 or Sybase licenses before August 1, 2014 and have not purchased more licenses since that time, your licenses were core-based. Core-based licenses have been converted to instances at a 4:1 ratio, and the new license keys in your Customer Portal reflect this converted amount.
- If you initially purchased or bought additional licenses after August 1, 2014, your licenses are instance-based. The new license keys in your Customer Portal will reflect the purchased amount.
What should I do?
We recommend that you upgrade to the latest version of DPA available in your Customer Portal and activate your license keys before November 10, 2015. This will correctly align product enforcement with the licenses you purchased.
Are there other benefits to upgrading?
Yes, DPA has made a lot of progress since 9.0 was released:
- 9.1 added support for Amazon RDS databases, excluding SQL Statements from trend graphs and event annotations
- 9.2 added integration with Orion
- 10.0 added MySQL support
- Bug fixes, security updates, and speed improvements
If you have any questions or concerns, please contact customer service at your earliest convenience. We apologize for the inconvenience and look forward to helping you quickly through this final transition of DPA licensing.
升级步骤：
1：首先你必须通过账号去官网下载安装文件。它提供Windows和Linux两个版本。我下载了Linux版本安装文件SolarWinds-DPA-v10.0.352-SR1--Linux-Unix.tar.gz
2:解压SolarWinds-DPA-v10.0.352-SR1--Linux-Unix.tar.gz安装包，然后查看 readme.txt，你会看到下面升级指导步骤。强烈建议升级前，先看看reade.txt的UPGRADE INSTRUCTIONS。
3：还是建议将指导文档的步骤调整一下，首先停止DPA的服务，禁用任何关于SolarWinds DPA的cron jobs。
