different default logfilsiz on two aix nodes

[eurodba]

Hi

I get different default settings for logfilsiz logprimary & logsecond on two different nodes.
Both node running aix 6.1 and DB2 v9.5 fixpack 3

After performing db2 create db test1; on both nodes i get different db cfg's

node 1 has the normal defaults
Log file size (4KB) (LOGFILSIZ) = 1000
Number of primary log files (LOGPRIMARY) = 3
Number of secondary log files (LOGSECOND) = 2

node 2 has different settings
Log file size (4KB) (LOGFILSIZ) = 1024
Number of primary log files (LOGPRIMARY) = 13
Number of secondary log files (LOGSECOND) = 4

I can't explain the difference.

Did I miss a DBM parameter?

Thanks in advance
