Easiest way to move data from one instance of Mango to another


  • Hi,

    I have a new installation of Mango (3.5) and I'd like to move a number of data sources, their points and all of their saved historic data off of another existing Mango server (3.4) into the new one.

    I've spent some time reading other posts in this forum dealing with a similar question, but I can't find a clear answer.

    https://forum.infiniteautomation.com/topic/3247/data-import-flexibility
    https://forum.infiniteautomation.com/topic/2514/data-import

    I know I can easily export and import the data sources I want and their points using the Configuration Import/Export feature in the emport.shtm page, and this works great.

    However I'm looking to move all their respective saved history data as well. I also know I can do a data point history export under the data_point_details.shtm and importing them in the dataImport.shtm page - but this can be tedious when dealing with a total of thousands of data points.

    Is there another easy way to achieve this WITHOUT having to duplicate/replicate the entire old Mango server (3.4) AND without having to manually do a CSV/Excel export and import for each one of the data points we care about?

    Thanks.


  • Hi ddiezperez,

    Yes, there is such a tool! I'm not sure what you mean,

    WITHOUT having to duplicate/replicate the entire old Mango server

    but with an H2 backup restored into a database (see this post for instructions on doing a restore at the command line) and the old Mango/databases/mangoTSDB, the "Mergration" tool on the /mango_no_sql.shtm page will do this. It relies on matching the XIDs from your current database to the restored database, and then imports data from the mangoTSDB it's pointed at (also the restored TSDB) into the running Mango. This is the correct course of action if you wish to restore data into a system that has been created through a JSON import, as the IDs may have changed and a simple NoSQL merge is not sufficient. So,

    1. Import JSON configuration
    2. Use Mergration tab on /mango_no_sql.shtm to point at the old H2 database and the old mangoTSDB directory

  • Hi Phil - thanks for the response. I ran into an issue.

    I exported a small subset of the data sources and their points and imported their JSON configuration into the new Mango server.

    I copied the entire Mango/databases/MangoTSDB directory from the old Mango server into a Mango/databases/MangoTSDB_fromDot41 in my new Mango server.

    Then I went ahead and used the "Merge TSDB Data Into Mango" tool in the /mango_no_sql.shtm page. I pointed the Source TSDB location to the MangoTSBB_fromDot41 directory I mentioned above and left all the other settings at default value.

    I got the following error within a few seconds: Merge failed, you need 6248 available file descriptors but only have 3422

  • @phildunlap said in Easiest way to move data from one instance of Mango to another:

    Yes, there is such a tool! I'm not sure what you mean,

    WITHOUT having to duplicate/replicate the entire old Mango server

    What I meant was: the intention of the new Mango server is not to be a replica of our existing Mango server - I don't want to move all the datasources and datapoints - I only want a select subset. Hence why I don't want to restore the entire database of the old Mango server into the new Mango server, I only want the datasources and points I care for and their history.


  • Merge or Mergration ? You need to do a Mergration if you restored the configuration from the JSON import. Not Merge.

    I got the following error within a few seconds: Merge failed, you need 6248 available file descriptors but only have 3422

    Ah, dreaded file descriptors! One solution is to adjust the /etc/security/limits.conf file for the user on the operating system that is launching Mango to have a line like,

    Username hard nofile 50000
    

    You can use a larger value, or 'unlimited' if you want. Then you'll need to log out of SSH and back in (if you're starting Mango as that user) and have a script in Mango/bin/ext-enabled like,

    #!/bin/bash
    #fdLimits.sh
    case "$1" in
        init)
            ulimit -Hn 50000
            ;;
    esac
    

    Then stop, and start Mango for that to get applied. If you are launching Mango in the same SSH session you're logging in as, you can just run the ulimit command, but you'll want it as an ext-enabled script so that whatever session invokes Mango (like maybe a service kicking off Mango under an appropriate user) will have the limit for file descriptors appropriately raised.


  • @phildunlap said in Easiest way to move data from one instance of Mango to another:

    I used the "Merge TSDB Data into Mango" tab. You are saying I should have used the "Migrate NoSQL Data Into Mango" - correct? Just want to be clear as I'm unsure of what the "Mergreation" tool is ..


  • Oh, look at that, someone must have changed the tab names and I hadn't noticed. Yes, you want the "Migrate NoSQL Data Into Mango" tab. That should have inputs for an SQL database and a NoSQL database. Originally there was Migration (from SQL) and Merge (from a same-point-ids NoSQL) and so I called the 'both' type a Mergration. I guess that didn't stick!

    Edit: It looks like ten months ago Mergration became NoSQL Migration - sorry for my confusion.


  • Oh, look at that, someone must have changed the tab names and I hadn't noticed. Yes, you want the "Migrate NoSQL Data Into Mango" tab. That should have inputs for an SQL database and a NoSQL database. I guess someone else didn't like 'Mergration' either. Originally there was Migration (from SQL) and Merge (from a same-point-ids NoSQL) and so I called the 'both' type a Mergration. I guess that didn't stick!

    Ha gotcha - Thanks for the clarification.

    I just gave it a try and looks like having the Mango Internal data source in both servers is a problem when trying to migrate NoSQL data into Mango.


  • Are you getting an error? That should work fine, the only issues will arise if you have XIDs that exist in both SQL databases but are not the same data types.


  • Getting this ... even after renaming the XID of the Mango Internal data source

    org.h2.jdbc.JdbcSQLException: Table "DATAPOINTS" not found; SQL statement: select id from dataPoints where xid = 'internal_mango_num_active_user_sessions' [42102-196]
    

    That shouldn't prevent the rest of the data migration to complete though - correct?


  • Check to make sure your connection string is good. One interesting behavior of H2 is that if you point your connection string at a location that doesn't have a database and try to log into it with credentials, it will create a new, empty H2 database there. That would then not have a dataPoints table to query upon!

    Should be something like,

    jdbc:h2:/path/to/old-databases/mah2
    

    and probably the best connection string for H2 may also have the arguments added on the db.url normally in H2Proxy, which would be

    jdbc:h2:/path/to/old-databases/mah2;DB_CLOSE_ON_EXIT=FALSE;MV_STORE=FALSE;IGNORECASE=TRUE
    

    And you can optionally add ;IFEXISTS=TRUE to the end to ensure it won't just create a new, empty H2 database if the connection string isn't quite right.

    I will make the change in this issue to this type of migration as well: https://github.com/infiniteautomation/ma-core-public/issues/631


  • Thanks for the help Phil - it is processing right now .. Keeping the fingers crossed.

    If this works correctly then I'll go back and do a JSON config import of the rest of the data sources and points I care about and repeat the process.

    This will be really helpful when integrating sites/controllers for clients on a dev/test Mango server first and then migrating the data and polling to the client's production environment.

    I'll report back after it is done processing ..

    UPDATE: status went to IDLE and it seems to be frozen at Run Time of 67 seconds. What can I check?0_1539109844073_Data_Migration.PNG


  • Log file. I saw something like that recently where corruption exceptions were killing the merge task I tried to run. Was quite irritating. A shame we haven't released 3.5.1 of NoSQL yet, as I put retries into the Merge and the NoSQL Migration should there be corruption in a shard in the NoSQL. Maybe I can email you a pre-release of that....


  • Connection string is pointing to the right directory and file, and I used the suggested arguments as well. It is pasted below:

    jdbc:h2:file:/Mango/databases/_fromDot41/mah2;DB_CLOSE_ON_EXIT=FALSE;MV_STORE=FALSE;IGNORECASE=TRUE;IFEXISTS=TRUE
    

    Latest ma.log file pasted below. Sorry I keep pasting the entire file within the post, if there's a better way to share it please let me know.

  • We moved to email, but the next version of MangoNoSql, 3.5.1, will improve the handling of corruption in the database that is to be merged. This is what caused the buffer overflow exception at the end of the log, and the returning to IDLE state before finishing all the data points.

    Sorry I keep pasting the entire file within the post, if there's a better way to share it please let me know.

    Tis better to log the whole log than no log at all!
