Check Postgres’s log - good chance you run out of shared memory

YES !!

I have increased the shared memory, and now no error

sudo nxdbmgr upgrade

Upgrading database...

Core database schema is up to date

Database upgrade succeeded

postgres psql -d netxms -c "SELECT * FROM idata_16066 LIMIT 10;"

dlauwers, twparker
can you run
nxdbmgr -t upgrade

This is to see what exactly it's doing there

Hi, this is the result

It is "working on" Create Table tdata_16066 for about 5 minutes and then it fails

  1. Check if idata_<id> exists
  2. If the table is empty → DROP it
  3. If the table is not empty → RENAME it to idata_v5_<id>
  4. Create a new idata_<id> table using CreateIDataTable(id)

Pls check, do you have
idata_46970
idata_v5_46970
tables in the DB?

If idata_46970 is there, pls show output of

DROP TABLE idata;

DROP TABLE tdata;
CREATE TABLE tdata

Is my database irrevocably damaged?

Did all the updates/upgrades to be on 6.01, rebooted, bus till

NetXMS Database Manager Version 6.0.1 Build 6.0-469-g5e68d5db1d

Any fixes or workarrounds ?

Thanks

I can see that the database upgrade is happening in the background, but the netxms-server service won't start.
"Your database has format version 60.7, but server is compiled for version 60.32"

Are you still in upgrade to 6.0.0, or you've restarted upgrade to 6.0.1?

...happening in the background - is it nxdbmgr background-upgrade running? If so, you need for it to finish and then run nxdbmgr upgrade again - it will upgrade schema further. This step could be a background one in 5.2, but when upgrading to 6.0 we need it to complete prior to subsequent db upgrade steps.

C:\NetXMS\bin>nxdbmgr check
NetXMS Database Manager Version 6.0.1 Build 6.0-469-g5e68d5db1d

Error loading configuration file

Make sure you run this in cmd session started with administrator rights - looks like there's access right issue to the server config file.

Message Your database has format version 52.23, but server is compiled for version 60.32 means that nxdbmgr upgraded did not happen (first part of format version is basically netxms version, so 52.23 means that database format is for 5.2.x).

nxdbmgr check will tell that db version is old, so try running nxdbmgr upgrade

I restored the db back to the version 5.2.8 before i updated to 6.0.0

I've then run the new version 6.0.1 but the core service will not start, log file says:

2026.02.10 08:47:19.444 *E* [db] Your database has format version 52.23, but server is compiled for version 60.32

If i then try 'nxdbmgr check' i get:

C:\NetXMS\bin>nxdbmgr check
NetXMS Database Manager Version 6.0.1 Build 6.0-469-g5e68d5db1d

Error loading configuration file

Any ideas please?

I am running into a similar issue on a Ubuntu installation where the database has taken multiple days to upgrade showing that it is converting idata and tdata tables, but never completing.

Thanks in advance!

Unfortunately, the same problem here.

Best Regards!
