NetXMS Support Forum

I am trying to upgrade vrom 1.2.13 to 1.2.16 and during the database upgrade I get the following:

nxdbmgr upgrade -t
NetXMS Database Manager Version 1.2.16 Build 7884

Upgrading database...
Upgrading from version 324 to 325
>>> SELECT map_id, element1, element2, element_data, color, status_object, routing, bend_points FROM network_map_links
Segmentation fault

Any ideas on how to fix this?

Exactly the same issue under FreeBSD (FreeBSD 9.3-RELEASE, mysql-server 5.5.39).

Indeed, FreeBSD port of NetXMS is broken now: it does not install shared libraries files required for both netxmsd and nxagent (i.e., libnxsqlite.so.1.0.0,libnxdb.so.1.0.0 and so on)  .

Please provide backtrace of this crash (details on how to get a backtrace: https://wiki.debian.org/HowToGetABacktrace#Running_gdb)

It seems that this is related to the maps.  I am not fully using my maps at the moment.  Could I remove the maps from mysql tables?  If so, what would the proper sql commands to get rid of the maps?

Hi,

I probably found the bug. Try to patch src/server/tools/nxdbmgr/upgrade.cpp as following:

Find line 492 - it should be

         TCHAR *config = DBGetField(hResult, i, 3, NULL, 0);

insert after it the following code:

         if (config == NULL)
            config = _tcsdup(_T(""));

Rebuild nxdbmgr - it should work.

Best regards,
Victor

Thanks!!  That fixed it.

Yes, this patch fixes the database upgrade crash.
Thanks!
