  • 1.  IMC MySQL max_connection error

    Posted Feb 12, 2016 07:39 AM

    HI

    I'm trying to install HP IMC+MySQL ver 5.7 and get error Checking Database Parameter Configuration... Not Passed The following database parameters do not meet the installation requirements. Please modify the configuration according to the iMC MySQL database installation and configuration guide and try again: max_connections

    My mysql config file

    # sort_buffer_size = 2M

    I set max_connections to 400 with MySQL 5.6, and that works.

    IMC 7.2 does not officially support 5.7 (only 5.5 & 5.6). That may be part of your problem (i.e. it's failing checks because of something else, but it gets misreported as a max_connections issue).

    What happens if you use 400, not 500?

    This is the contents of my my.cnf file. Works with both IMC 7.1 & 7.2, using MySQL 5.6 on RHEL 6.x.

    socket=/var/lib/mysql/mysql.sock
    user=mysql
    # Disabling symbolic-links is recommended to prevent assorted security risks
    symbolic-links=0

    max_connections=400
    character-set-server=latin1
    default-storage-engine = INNODB
    lower_case_table_names=1
    innodb_buffer_pool_size=512M
    innodb_additional_mem_pool_size=16M
    max_allowed_packet = 200M
