I have a 2 data node mysql-cluster with 16gb memory and 10gb datamemory. I am trying to add two new data nodes on solaris 5.10 64 bit 16g ram machines. But I can't start the data nodes with more than 4Gb heap.

I have checked maxshm memory, max address memory, ulimit, os architecture, ndbd architecture and they all seem to be fit to be able to run.

Does Solaris have any other parameters to check for more heap space per process?

  • What error message do you get ? Are you using ZFS ? – jlliagre Dec 3 '13 at 23:11
  • this post can help you, serverfault.com/questions/156063/…, maybe your problem is you don't have enough virtual memory – c4f4t0r Dec 4 '13 at 0:30
  • I don't get any error message. But a 4gb core dump. @jlliagre. I am not sure of the file system. I can't reach the os right now. But I will check ASAP. – fsniper Dec 4 '13 at 11:51
  • @c4f4t0r: I have 4gb swap memory and swap -s reports 20gb virtual memory free. There are 2 nodes with same memory outline and ndbd are running fine there. – fsniper Dec 4 '13 at 11:52
  • stupid questione, your mysql software are 32 bit or 64 bit? – c4f4t0r Dec 4 '13 at 13:51
