The underlying Java library for generating Excel reports isn't great on memory usage, if you are generating too large of an excel file it can crash Mango. I would suggest you try running that report over a very small time range to see if that helps.

@mitchb6 said in Mango 3.7.7 free version will not start: Caused by: java.lang.NoClassDefFoundError: jdk/nashorn/api/scripting/ClassFilter The version/flavor of Java you are using doesn't have the nashorn scripting classes (which are required for Mango). We are working to migrate away from that but Mango 4.0.0 will still have this dependency too.

@dage here are some screenshots proving it works on the latest (un-released) Mango 4.0.0-SNAPSHOT The user is tpacker with only the user role: [image: vZrqxjV.png] The user tpacker viewing excel reports: [image: DR0A46v.png] Excel Report Permissions: [image: BDqsybk.png] Menu Item Permissions: [image: M6gN6gZ.png]

@cmusselm that setting may help depending on what you are doing. That setting will effectively send a short value to a register if it is 2 bytes according to the point locator's modbus data type. If it is > 2 bytes then no matter what it will send an array to the slave and likely will write > 1 register.

Ahh! That make sense. Thanks @MattFox !

Appreciate it @mattfox !

@mattfox thanks,I tested it your way and got some ideas

Use maStats (the statistics directive) and get the max value over your monthly time period. Fox

File store is on system running mango under the /opt/mango/filestore You'd require those files as well as the SQL database. Fox

Thanks for your reply and adding the noSQL licence, @CraigWeb! Regarding the other error: I wanted to migrate existing H2 data into noSQL and was mislead by the documentation: The NoSQL migration can take several hours to complete but it will happen in the background. My bad -- I thought it was a one-click solution given, that Mango knows which DB it is using and what the credentials are. Will report back when I had access to the client's server again. Thanks again for your help!

@cwangv Actually, Mango logs audit events for edit, delete, create user actions.

You are correct. Set each user in their respective timezones. Mango system will continue to use system timezone unless explicitly specified in the env.properties file. I half wonder if your mango system should run GMT then all offsets are based from a zero offset per user rather than an offset of an offset.. Fox
