Error description

  • If db2nodes.cfg has non canonical hostname at the second column,
    such as netname, service adaptor name, or "localhost",  as below
    example, db2pd or db2pdcfg with -dbp or -member option may run
    in an endless loop, and keep on spawning new db2pd or db2pdcfg
    process.
    
    ----
    0 hidehy01 0
    1 hidehy02 1
    2 hidehy03 2
    ----
    * above second columns are not 'hostname' command output but
    netname.
    
    If 'hostname' command returns hidehy1, hidehy2 and hidehy3 at
    each machines.
    Here is correct example:
    ----
    0 hidehy1 0
    1 hidehy2 1
    2 hidehy3 2
    ----
    * above second columns are output of 'hostname' command at each
    machines.
    

Local fix

  • Modify db2nodes.cfg to use canonical hostname at the second
    column of db2nodes.cfg
