Standby Server DB Replication
« on: January 15, 2019, 06:00:53 am »


I need a standby netxms server, i also want to ensure the secondary server has a 48 hours old data, i tried using mariadb delayed replication feature, with no success,

I ge the below error when the DB replicates

Last_SQL_Error: Error 'Duplicate entry '26022462' for key 'PRIMARY'' on query. Default database: 'netxms'. Query: 'INSERT INTO event_log (event_id,event_code,event_timestamp,event_source,zone_uin,dci_id,event_severity,event_message,root_event_id,user_tag,raw_data) VALUES (26022462,6,1547457625,166937,0,0,0,'Node status changed to NORMAL',0,'','\n   \"id\": 26022462,\n   \"code\": 6,\n   \"name\": \"SYS_NODE_NORMAL\",\n   \"timestamp\": 1547457625,\n   \"source\": 166937,\n   \"dci\": 0,\n   \"severity\": 0,\n   \"tag\": null,\n   \"message\": \"Node status changed to NORMAL\",\n   \"parameters\": [\n      {\n         \"name\": \"\",\n         \"value\": \"1\"\n      }\n   ]\n')'

is there something i need to do to get this setup working?

And now i got the error

i would down netxms daemon, then run
Code: [Select]
nxdbmgr -d -f check
restart netxsd daemon, did it fix anything? no? down netxms daemon again.

enter your mysql console, and use the netxms database

then, remove that duplicate entry with a mysql query

delete from netxms.event_log where event_id = 26022462;

exit, 'check' netxms database, restart netxms daemon, if a similiar issue occurs for what seems like infinity, you can repeat, or clear out the table with truncate netxms.event_log
