I have started your steps to correct this:

Step 1) Gain contact with the database...
H2:

Navigate to Mango/bin/h2-web-console.sh

• DONE
  Edit the script and add -webAllowOthers if you are not browsing from the same machine Mango runs on, and remember the port at the top (8081 by default).
• DONE
  Launch the script. Navigate to http://[ip]:h2-port/ in your browser
• DONE
  Fill in the credentials, and /path/to/Mango/databases/mah2 then connect
• ?? the path says it should be "mango/databases/mah2 but there is no mah2 folder or file in my databases folder

What do you want me to do from here?

Thanks

Brian

#MySQL database settings. Your MySQL instance must already be running and configured before this can be used.
db.type=mysql
db.url=jdbc:mysql://localhost/Mango_M2M
db.username=[valid username]
db.password=[valid password]

username and password removed but the ones listed are valid.

Again though the MySQL tables that are in that database are the ones created and used by Mango.

dataPointHierarchy, dataPoints, dataSources, eventHandlers, events, excelReportTemplates, excelReports, globalScripts, graphicalViews, mailingListInactive, mailingListMembers, mailingLists, maintenanceEvents, pointEventDetectors, pointLinks, pointValueAnnotations, pointValues, publishers, reportInstanceData, reportInstanceDataAnnotations, reportInstanceEvents, reportInstancePoints, reportInstanceUserComments, reportInstances, reports, scheduledEvents, selectedWatchList, systemSettings, templates, userComments, userEvents, users, watchListPoints, watchLists.

All of the data points are being kept in the NoSQL database.

#Database settings for conversion. If the db.* settings point to a new database instance, and the convert type setting
#is set, Mango Automation will attempt to convert from the convert.db.* settings to the db.* settings
#Note that database conversions should not be performed in the same step as an upgrade. First upgrade, then convert.
convert.db.type=
convert.db.url=${convert.db.url}
convert.db.username=${convert.db.username}
convert.db.password=${convert.db.password}

#Set the base path for where the NoSQL data will be stored
db.nosql.location=${ma.home}/databases/
#Set the folder name of the point value store
db.nosql.pointValueStoreName=mangoTSDB

These are the same settings I have been using for a while now with no problem.

I will try to force my service on to 2.7.10 as you suggest

3. Launch the script. Navigate to http://[ip]:h2-port/ in your browser
4. Fill in the credentials, and /path/to/Mango/databases/mah2 then connect

MySQL:

1. command line, mysql --user=[env's db.user] --password=[env's db.password] [databaseName]

Run the commands...

1. select * from systemSettings where settingname='databaseSchemaVersion'; is 11, is 12?
   if 11,
   Please post error from trying to start 2.7.10
   if 12,
2. update systemSettings set settingvalue='11' where settingname='databaseSchemaVersion'; drop table jsonData;

Disconnect from the database, and finally, start up with 2.7.10 in your Mango/ directory.

Please check your env.properties for your database setting. It would appear to me Mango is trying to create a new database on MySQL.

Yeah, you will need to drop the m2m2-core-2.7.10.zip into your Mango/ directory, then relaunch.

I can't get back to our mango site to do an upgrade the normal way.

I put a new Core version, 2.7.10, out to fix this issue.

After restarting the Mango service, it tries to start 2.7.8:

[root@M-2-M ~]# ma-start: MA started with Process ID: 3547
INFO 2016-03-16 16:04:11,233 (com.serotonin.m2m2.Main.main:82) -** Starting Mango 2.7.8** with Schema Version: 12

And I can see the updated modules getting loaded as well.

After the modules get loaded it looks like the same lines get put in.

I take you point that it looks like a Mysql error but I did not specifically set up any MySQL tables. These must tables that Mango use natively and used without error in 2.7.6 or are new tables in ver 2.7.8

bad SQL grammar [CREATE TABLE jsonData (id int not null auto_increment,xid varchar(50) not null, name varchar(255) not null, readPermission varchar(255), editPermission varchar(255), data clob, primary key (id))engine=InnoDB; ]

I don't know what table is 'jsonData'
It also looks like it is terminating something called Mango Lifecycle:

INFO 2016-03-16 16:04:14,263 (com.serotonin.m2m2.Lifecycle.terminate:344) - Mango Lifecycle terminating...
INFO 2016-03-16 16:04:14,279 (com.serotonin.m2m2.db.BasePooledProxy.terminateImpl:110) - Stopping database

Now I cannot get back into my mango to check any settings in any event.

Any advice would be greatly appreciated.

Brian

I think you should receck your settings, this error seems to be clearly a MySQL error and we only saw this error happen if using a MySQL database. You can look at your env.properties file and also go to the system settings page in Mango and see what it says as the Database type at the top.

ERROR 2016-03-16 12:58:49,644 (com.serotonin.m2m2.Main.main:120) - Error during initialization
com.serotonin.ShouldNeverHappenException: org.springframework.jdbc.BadSqlGrammarException: StatementCallback; bad SQL grammar [CREATE TABLE jsonData (id int not null auto_increment,xid varchar(50) not null, name varchar(255) not null, readPermission varchar(255), editPermission varchar(255), data clob, primary key (id))engine=InnoDB; ]; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version

I have a recent Mango back up to restore. We do an automatic back up each morning approx 5 am local time here.

I am halfway through uploading the 2.7.6 core files so will continue with that.

Thank you for your reply.

Cheers

Brian

When using MySQL as your database the best practice to follow is to first dump your database and then make a zip file of your Mango install folder this way you can always do a full roll back.
