Stacking of Quantity and Charge Adjustments Policies can cause negative charges

Affected versions

All versions of Exivity

Description

When creating two Absolute Discount Adjustment Policies, where both Policies apply to the same Account, Service and date Period, there is a chance of generating negative charges for the services where both Adjustment Policies apply to as can be seen in the following screenshot:

Workaround

The current workaround is to avoid stacking multiple Absolute Adjustments for each unique Account + Service combination. Instead, try to combine them within a single Adjustment Policy

Status

This issue is currently being resolved (internal reference: EXVT-<TBD>) and will be included with the release after version 3.5.7.

Installing or Upgrading to version 3.5.6 populates invalid RabbitMQ settings

Affected versions

Exivity versions 3.5.0 till 3.5.6

Description

When installing or upgrading to version 3.5.0 - 3.5.6, when installing RabbitMQ on the local system, the initial configuration values are incorrectly populated:

Workaround

To work around this issue, you may uncheck the checkbox Install Local RabbitMQ Engine and then check the same checkbox again. The values will now be correctly populated.

In case you have already executed the upgrade progress and your system is broken, you will need to change the config.json to align the mq settings:

"mq": {
        "servers": [
            {
                "host": "localhost",
                "port": 5672,
                "secure": false
            }
        ],
        "user": "guest",
        "password": "guest",
        "vhost": "/",
        "nodeID": "TR2021",
        "redialPeriod": 5
    }

Status

This issue is currently being resolved (internal reference: EXVT-5042) and will be included with the 3.5.7 release.

Discount Adjustments are created as Premium

Workaround

In order to create a discount policy in version 3.5.5, use the API interface to create one.

Status

This issue is resolved with the 3.5.6 release.

Installer upgrade generates an error: Error opening file for writing

Affected versions

Exivity versions 3.5.0 and higher

Status

This issue is pending. (internal reference: EXVT-1337)

Exivity Backend Service does not start / access to merlin.exe has been denied

Affected versions

Exivity version 3.5.0 and higher

Description

Some Anti-Virus software vendors (specifically: McAfee and APEX) incorrectly flag the Exivity binary merlin.exe as a backdoor/trojan horse. As a result, the Exivity Backend Service might not be able to start as shown in the example below:

Backend Service might not be able tostart

The Windows event viewer may display the following error (depending on your A/V vendor):

A/V software may deny access to merlin.exe

Resolution

Response by certain A/V vendors:

[merlin.exe] is detected by [a coupe of] AV's as a BackDoor as it's functionality is very similar and malware authors can use this to their own advantage to compromise systems and gather sensitive system information.

We also understand that [merlin.exe] can be used for legitimate purposes and therefore we will change the classification of the sample submitted to PUP. This way will be able to exclude detection through our scanner configuration but at the same time we are still protecting our customers who may be not be aware of this software running on their systems.

Hence if you want to allow this application in your environment kindly exclude it by detection name.
