Oracle Cloud Infrastructure (OCI) GoldenGate is a managed service providing a real-time data mesh platform, which uses replication to keep data highly available, and enabling real-time analysis.
Desktop Operating System upgrades and migrations to ensure installed applications are compatible with the new environment. If an environment does not have a lot of locally installed applications and heavily dependent on web applications, cloud applications, and Microsoft App-V, then AppDNA is not going to be beneficial in that organization.
I think it's a great product. We apply Oracle GoldenGate to several use cases in our organization. 1. Business Continuity Planning, 2. Query Offloading through data replication to a reporting instance of our data, 3. looking into data transformations to help support various queries for different teams within the business.
Citrix AppDNA has a user friendly interface for admins to use and the product is updated well by Citrix Support.
It does not take a lot of resources to deploy AppDNA and can be done within a work week even for a large environment.
The reports not only show compatible and incompatible applications, but provide suggested solutions for incompatible applications to resolve and make them compatible with new Operating System.
If you have Citrix XenApp or XenDesktop Platinum, AppDNA is included and no additional cost.
Citrix AppDNA should get more frequent updates on application compatibility list and provide even more detailed suggestions for fixes and perhaps auto-fix feature for some applications.
Compatiblity with legacy Operating Systems could be expanded to include more applications and OS to increase usability.
A good essential tool that should be marketed more by Citrix to organizations for usage beyond Citrix environment. Most non-Citrix IT personnel and management are unaware of the benefits of AppDNA and it's ability to help with desktop Operating System migrations.
Once set up, it's very easy to use and keep running, it's getting to that point that can make it cumbersome to some. Also, depending on the data that you want to replicate, the configuration files can become quite cumbersome to maintain. Learning curve can be high for some who are not as experienced with databases and transactions.
Oracle Support for Oracle GoldenGate has been quite responsive and quite helpful in the few situations where we've needed it. Furthermore, the documentation on Oracle GoldenGate is so good that we often do not need to contact support with issues as the fix is already documented and able to be run by us without needing to open a ticket.
We've had Oracle consultants come as well for training days to talk about new features, parts of Oracle GoldenGate we may not be using and things of that nature. The consultants they send are great as they're very knowledgeable about all things Oracle GoldenGate and great resources for any questions or concerns you may have with the product.
We used Oracle University for our Oracle Golden Gate Training and it was top notch. We were able to turn our whole DBA team to Oracle GoldenGate newbies to Oracle GoldenGate troubleshooting experts in a matter of a few days, while this obviously did not come cheap, the company felt that it was worth the investment.
If Oracle GoldenGate is new to your organization, expose as many DBAs as possible to it. Having your whole team fluent in it will overcome early operational hurdles and allow it to more quickly become an accepted and supported part of your supported platform for your team that will enable the business to use it to its fullest.
AppDNA is more robust and provide a nice report of application compatibility list to review and segment verified applications from problematic applications. It takes one step further from the Microsoft Windows Migration Tool by providing solutions to fix the problematic applications.
We use Oracle Data Guard as a backup tool, but not for data replication. Data Guard is not suited for real-time data replication in our non-normalized reporting database nor for the database we are using for our upgrade project, as Data Guard is not able to transform data and is not able to synchronize data into different schemas, which is necessary for our project. Additionally, our project database is on Oracle 12g not 11i: I am not 100% sure Data Guard is able to replicate from 11i to 12g
Have never had any issues with scaling Oracle GoldenGate itself, however Oracle GoldenGate Monitor does have scaling issues, but with Oracle GoldenGate now able to be monitored by Oracle Enterprise Manager, this is no longer an issue, in my opinion.
AppDNA was relatively easy to deploy with a small team of 3-4 support IT personnel and took a week to deploy and another week for us to configure and use.
Great tool to cut down on manual process of testing initial application compatibility before system upgrade.
If you are a Citrix Platinum customer, there is no reason not to use this tool and a great way to consider upgrading to Platinum if you are an Advance or Enterprise customer.
For a single large organization (over 3000 desktops), if you are planning a desktop Operating System upgrade you need to take a look at AppDNA.
In earlier versions, DDL support was limited as well as the need of primary key constraints in the source tables. This made me create partitions, sub-partitions, truncatations and perform other operations upon they are performed in source systems and I need to discuss with source system administrators and need to convince them to let them create primary keys for replicated tables.
But both issues are solved now.
Installation is straightforward, easy.
Deployed everything within Oracle Data Integrator.
Developing 1000 of ODI interfaces for loading into Operational Data Store took not more than 100 man/days. But, adding them to Golden Gate is taking not more than 5 man/days.
Management Pack and VeriData are additional packs for your management and data verification needs.
