What does V8R0 of HA4i look like?

While we wait for IBM to get back to us about our PowerVM activations (3 days and counting, I often wonder does IBM want to service clients?) I thought I would start to show some of the changes we have made in the next release of HA4i. The announcement date for the next release is a little way off as we still have to get the manual and new PHP interfaces finished, but we all feel excited about some of the new capabilities so we thought we would start to share.

As the PHP interface is not completed and we have found the IBM Access for Web product is performing very well, we thought it would be an ideal opportunity to show it off at the same time we display some of our new features. So far the displays have been pretty pleasing with no problems in showing the content effectively. Again we will point out the fact that the web interface is being run on one system (shield7) and the system running HA4i is another (shield8), the ability to launch a 5250 session from the web interface to another system without the web software running on that system is pretty neat in our view.

The first screen we will share is the main monitoring screen, this is a screen shot of the 5250 green screen output using the standard Client Access emulator.

Here is the IBM Access for Web output of the same screen, we have placed arrows and markers to show some of the features which we will describe below.

Roleswap Status Access for Web

Roleswap Status Access for Web

Arrow 1.
A)These are the options that are available against each of the environment definitions, these can be used to drill down into more specific data about each of the processes involved in the replication of the objects and data.

B)You will notice that we can end and start each environment separately, there is also an option on the operations menu which will start and stop every environment at once.

C) You can Roleswap each individual environment, the previous version only allowed a total system Roleswap.

Arrow 2.
A) Some environments should not allow Roleswaps to be carried out, we have defined 2 such environments to replicate the JQG4i data. Because the data is only ever updated on the generating system and each system has its own data sets you would never want to switch the direction of replication. The Y/N flags show that the BATCHTST environment can be switched while the JQG4i environments cannot.

Arrow 3.
A) These are the environment names, each environment runs its own configurations and processes.

Arrow 4.
A) This is the mode of the environment on this system *PROD states that this is a source system where the object changes are captured while the *BACKUP is where the changes will be applied. when viewing the remote system these roles will be reversed.

Arrow 5.
A) If there are any errors or problems found within any of the replication processes you should not carry out a roleswap, HA4i retrieves the status from both the local and remote system to determine if an environment is capable of being roleswapped based on the state of the replication processes. As you can see if an environment should not be roleswapped the entry is marked as *NA.

Arrow 6/7/8.
A) This is the state of the various replication processes, *GOOD states that there are no errors and everything that should be running is. *NOCFG states that no configurations exist that require the replication process to be running. Data status is the journal apply process and which could encompass more than one apply process if there is more than one journal configured to the environment.

Arrow 9.
A) You can view the configs from any system but changes to the configs can only be carried out on the *BACKUP system. the configuration pages can be accessed using this button (F17 on the 5250 Green screen).
B) The Remote Sys button (F11 on the 5250 green screen) just displays the remote system information.

There are a lot more new features in the next release which will make HA4i more competitive in complex environments, over the next few weeks/months we will show you what they are and why they are important. The big take away from above is the ability to define a much more granular approach to your replication needs. Becuase we can define multiple systems and multiple environments HA4i is going to be a lot more useful when you need to migrate to new hardware and expand data replication beyond 2 systems.

We hope that you like the features and if you are looking at implementing a new HA solution or looking to replace an existing one that you consider HA4i.
