<![CDATA[NetXMS Core server will not start after upgrade to 7.*]]>I have a windows server that has been running NetXMS 5.02 fine for some time, and I attempted an install ( upgrade ) to 7.0.2, and once upgraded the core services will not start.  Can someone please assist me in getting this running again, I have restored from backup and tried several times with the same results.

I receive a error in the windows log below:

It was public for a while, so please change it anyway.

"Connection refused" means the core service still isn't running, so the client has nothing to connect to. The most likely reason is that the database schema wasn't upgraded. The installer runs the upgrade hidden, so if it fails you see nothing, and netxmsd refuses to start on an old schema. Please run this from an elevated command prompt:

cd C:\NetXMS\bin
nxdbmgr upgrade
netxmsd -D 4

The first command shows any upgrade error directly. The second runs the server in the foreground with debug output, so you can see where it stops. If either one fails, post the output here, or the end of C:\NetXMS\log\netxmsd.log.

The crash in prunsrv.exe is the Reporting Server service ("NetXMS Reporting Server"), not the core. The NetXMS Core service is netxmsd.exe and gets its own service entry. The reporting server needs a 64-bit Java 11 or later, where 5.0 ran on Java 8. If you don't use reports, set that service to Disabled for now.

For the core itself, what is in DBDriver in C:\NetXMS\etc\netxmsd.conf? I suspect it's mysql.ddr. In 7.0 the separate MySQL driver was removed and MySQL is served by the MariaDB driver. The upgrade keeps your old config and leaves the old 5.0 mysql.ddr in place, and that driver can't be loaded by 7.0. The server stops at startup, and the database upgrade step in the installer fails silently for the same reason. If that's the case, change the line in netxmsd.conf to DBDriver = mariadb, then run:

cd C:\NetXMS\bin
nxdbmgr -c C:\NetXMS\etc\netxmsd.conf upgrade
net start netxmsd

A direct upgrade from 5.0.2 to 7.0.2 is fine. nxdbmgr goes through all the intermediate versions itself.

If your database isn't MySQL, or it still won't start, please attach the last 50-100 lines of C:\NetXMS\log\netxmsd.log.
