NetXMS Support Forum

Hello
I installed version 2.2.4 on Debian 9
There is a problem installing the database
By installing the following command, I installed the miradb installed
apt-get install mysql-server

I built the database with the following command
mysql -u root -p mysql
mysql> CREATE DATABASE netxms;
mysql> GRANT ALL ON netxms.* TO netxms@localhost IDENTIFIED BY 'netxms';
mysql> \q
And I also want to install the database with the following error that I encounter
root@debian:~# nxdbmgr init /usr/share/netxms/sql/dbinit_mysql.sql
NetXMS Database Manager Version 2.2.4 Build 9506 (2.2.4) (UNICODE)

Initializing database...
SQL query failed (Specified key was too long; max key length is 767 bytes):
CREATE TABLE userdb_custom_attributes (   object_id integer not null,   attr_name varchar(255) not null,   attr_value longtext not null,   PRIMARY KEY(object_id,attr_name) )
Database initialization failed

The version number of the database used in my system is automatically installed with the above command

root@debian:~# mysql

please guide me

Hi,

I suppose it has something to do with selected database encoding, because it says that length of integer + varchar(255) key exceeds 767 bytes. As a workaround try to edit init script and reduce size of attr_name column in userdb_custom_attributes to 127 (you will not encounter any issues during server operation).

Best regards,
Victor
