    Unanswered: 9.7 upgrade to 10.5

    On 9.7 FP11 upgrading to 10.5 FP8. In the IBM documentation it states to increase logging before the upgrade. But it does not give any hints as to how big it should be and also if you have big log files, you may not need to increase logging. Does anyone have more specific information or experience?

    To ensure sufficient log file space is available, you can set the logsecond database configuration parameter to twice the current value of logprimary and logsecond if the file system containing the log files has enough disk free space to increase this parameter. If you already have available a large log file space, it might not be necessary to increase this parameter. Also on partitioned database environments, you only need to increase the log space in the catalog partition.
