      You could try converting this instance over to MySQL. There was an issue with H2 databases growing that didn't get a true resolution until the 3.4 series with the persistent publisher, for instance. MySQL does not have the same issue with binary data sections not getting reused or freed when updated.

        I'm trying to convert it to mysql,
        so I've installed MySQL 8, created a schema named "mango"

        then in my env.properties I've now:

        db.type=mysql
        db.url=jdbc:mysql://localhost/mango
        db.username=solergy
        db.password=secret
        db.mysqldump=
        db.mysql=

        convert.db.type=h2
        convert.db.url=jdbc:h2:${ma.home}/databases/mah2
        convert.db.username=
        convert.db.password=

        but the result is that:

        INFO 2018-10-03 18:22:00,037 (com.serotonin.m2m2.db.BasePooledProxy.initializeI

          I would it'd be the db.url that would be going wrong. Two things could be at issue,

          1. It's not interpreting the absence of port as the default port, resolve this by explicitly adding a :3306 like jdbc:mysql://localhost:3306/mango
          2. localhost is not resolving to an address that comports with the bind address in your MySQL configuration (like ::1 if it's not enabling IPv6). Resolve this by adjusting the bind address in the MySQL configuration, or by trying the explicit local address instead of the hostname, like jdbc:mysql://127.0.0.1:3306/mango

          But a lot of error output is missing in your post, such as the 'caused by' section in the stack track. It could be that you do not have the users credentials or privileges correct. Consult this thread for instructions on creating the MySQL database, a user, and granting privileges on that database to that user: https://forum.infiniteautomation.com/topic/3559/convert-from-h2-to-mysql-database-guidelines

            according to your suggestion now the env.properties is the following:

            db.type=mysql
            db.url=jdbc:mysql://127.0.0.1:3306/mango
            db.username=solergy
            db.password=secret
            db.mysqldump=
            db.mysql=

            convert.db.type=h2
            convert.db.url=jdbc:h2:${ma.home}/databases/mah2
            convert.db.username=
            convert.db.password=

            the mango database for user solergy is created, granted and up and running:

            0_1538643566987_MySQL Running.JPG

            but still mango doesn't start:

              Did you perchance change the db.stream property to true ?

              I don't believe we've done much testing against MySQL 8 (thanks for posting the version information!), so it's possible there are issues related to that. You could try and older version and see if that works out of the box. I know 5.5 has been used a great deal.

                Hy,
                db.stream is unchanged, this is remaining properties for db on env.properties:

                db.forceUseIndex=true
                db.fetchSize=-1
                db.stream=false

                maybe I've to choose a certain character encoding in mysql?

                  No, I wouldn't think so. It's never come up in the past, but I think few people were using the MySQL server version released last April and they may be new issues. I did search the error a little and find something in the code that may have something to do with it, but I do intend to look into this more and try to run on MySQL 8.

                    I installed MySQL server 8 on my Windows machine and found I could convert an H2 database without issue. I also tried telling Java that it was in Italy (in case locale was affecting the getServerCharacterEncoding method) but it still converted without issue.

                    maybe I've to choose a certain character encoding in mysql?

                    This is done for you in the MySQLProxy class, it modifies the db.url for UTF-8:
                    https://github.com/infiniteautomation/ma-core-public/blob/main/Core/src/com/serotonin/m2m2/db/MySQLProxy.java#L28

                    A suggestion I saw is to try the latest JDBC. This is a 2.8 system? I would guess you have a very outdated Mango/lib/mysql-connector-java-x.y.z.jar file. You could try the version bundled with the latest Mango 3, or you could download the latest MySQL jdbc jar and replace the outdated with the new. You can download the latest here: https://dev.mysql.com/downloads/connector/j/5.1.html

                      Ok,
                      after driver change, installation is started but after a long while during migration I had this error,
                      can I do something to avoid it and continue migration?

                      I think the problem could be that pointvalue is nullable

                      0_1538733423521_PointValues.JPG

                      you suggest me to clean values with an sql like
                      "delete from pointvalues where pointvalue is null;"
                      ?

                        That looks like it would be caused by MySQL not supporting NaN, Infinity, or -Infinity as valid values in a column described as a double. If one has Mango already running on MySQL and attempts to set the value of a point to NaN, you get 0, if you do Infinity, you get Double.MAX_VALUE

                        But for converting, it doesn't look like there's any handling for the differences in what values are acceptable in one database or another. You could fix this by removing or changing these values before doing the conversion, by running this either through the Mango/bin/h2-web-console script or on the /sqlConsole.shtm page of Mango running on the old database:

                        -- for use to remove values from the H2 pointValues table that cannot be brought into MySQL
delete from pointValues where pointValue=CAST('NaN' AS DOUBLE PRECISION)
delete from pointValues where pointValue=CAST('Infinity' AS DOUBLE PRECISION);
delete from pointValues where pointValue=CAST('-Infinity' AS DOUBLE PRECISION)

                        Most commercial users use the NoSQL database to avoid problems with larger point values tables (since in Mango 3 all licensed cores can use the NoSQL database, unlike in 2.x where it is a separate license). That's probably why the issue has not been significant in the past. If you want to use SQL to store your point values, you definitely have to keep that table size under control or Mango will begin to slow down.

                          The db convertion from H2 to mysql is running (10 hours just to convert table pointValues) but I think there's something strange, at the moment I have only data from last 80 days concerning about 100 variables stored at 1 sample/minute, so I think 80x100x60x24=11,5Million rows in table pointValues, instead the table is around 40Million points, corresponding to an H2 database of 3.5GB corresponding also to a mysql pointValues table using 3.5GB.
                          To delete data before last 80 days (originally 5 months) I used the datasource purge for each used datasource. The purge from admin settings seems not to work on a big H2 database or in any case it tooks a very long time.

                            I'm searching for the reason why my H2 database is growing so fast,
                            I think that this "Logging TYpe = All Data" could be an error:

                            0_1540911037597_4c7aaf62-9c9e-42cb-b899-46a732b463d2-immagine.png

                            but, looking at the data, it seems that it takes a new value each minute

                            0_1540911699158_fd273f3b-9581-4fd4-9d7d-c6dc71f626ca-immagine.png

                            according to Data Source logging

                            0_1540911832921_2c348e4c-937b-4992-a809-89c0df8ef98b-immagine.png

                            so, it seems, it is not a problem, is it right?

                              If you are not using the NoSQL database, yes pointvalues are a contributing factor to the database expansion (and in some people's cases probably the only factor). But, the issue is here: https://github.com/infiniteautomation/ma-core-public/issues/1344

                              The likelihood is that sometime (probably sooner than later, maybe 3.6?) we will have a DB upgrade that does the necessary side work to upgrade an PageStore H2 database created in 196 to 197, as referenced in the issues referenced in that issue. In version 197 of H2 the problem of saving a LOB not reusing space has been resolved.

                              But, if something like your pointValues pointValueAnnotations or events tables are just very full, the next version of the database may not help in your case.

                                  I used this query to search for datapoints to reduce:

                                  SELECT count(*) as totale, dataPointId, d.name FROM pointValues p, dataPoints d 
where p.dataPointID = d.id
group by p.dataPointId , d.name order by totale desc;

                                  I will tune the results of this query,

                                  I also founded 8500000 records in PointValueAnnotations all like the following row

                                  TEXTPOINTVALUESHORT | TEXTPOINTVALUELONG | SOURCEMESSAGE        
--------------------+--------------------+----------------------
                    |                    | scripting.annotation|

                                  are these rows useful for something or I can delete it?
                                  Who produce these rows?

                                  Thanks, Antonio

                                    That is a consequence of a Scripting data source setting points that belong to other data sources, so that those values can be seen to have come from elsewhere after the fact. Yes you could delete those rows, you may possibly have to do a backup and a restore to reclaim the disk space.

                                      Thanks, I will delete such rows but I think other similar rows will be created in the future, there's a way to avoid this?

                                        Our solution was to code up the NoSQL module so that people wouldn't have trouble with their pointValues tables. That's the surefire way to avoid it.

                                          At the end tuning datapoints purge I'm arrived to a reasonable size for H2 database, about 1.5GB, now I'm testing the mysql porting of this database. I've 2 troubles:

                                          1. backupMysqlWithOutDatabase:442) - java.io.IOException: Cannot run program "mysqldump"

                                          the mysql setting on env.properties is the following:

                                          # MySQL database settings. Your MySQL instance must already be running and configured before this can be used.
db.type=mysql
db.url=jdbc:mysql://127.0.0.1:3306/mango
db.username=solergy
db.password=secret
db.mysqldump=
db.mysql=

                                          what is required in "db.mysqldump" and "db.mysql" fileds?

                                          1. When using excel reports purge I've the following exception

                                          0_1541496296046_46cd4e6c-ef45-4f41-8fe0-21b09d0e54b8-immagine.png

                                          what's the problem and how to solve it?

                                            what is required in "db.mysqldump" and "db.mysql" fileds?

                                            The path to invoke the mysqldump or mysql programs (or just the executables if they're on the Mango user's $Path). The error,

                                            backupMysqlWithOutDatabase:442) - java.io.IOException: Cannot run program "mysqldump"

                                            Indicates mysqldump is not on the path.

                                            what's the problem and how to solve it?

                                            That issue appears to have been solved in version 3.1.3 of the excel reports module. You will probably needs to work around it by manually deleting from the excelReports table and deleting from Mango/web/modules/excelReports/web/report-data/ as appropriate. It may only be one report with a null filename, you could perhaps investigate the excelReports SQL table to see.
