How to run db2ckmig on all DB partitions?

Question

We need to check the readiness of our DB for the migration to 9.5.
Could you inform us how to run db2ckmig on all DB partitions? Exact syntax and steps are appreciated.
Thanks!

Hi Jennifer.
If all of your partitions are physical partitions (i.e. a separate physical machine for each), then you can run db2_all as the instance owner directly as follows:
db2_all "db2ckmig <dbname> -l /tmp/db2ckmig.log"
However, if you are using multiple logical partitions on each physical machine, you run into problems with collisions accessing the same log file from multiple partitions on the same machine.  In this case, you must write a script or some sort of loop to automate this process.  For example, you can do something like this on windows:
for /F "tokens=1" %1 in (db2nodes.cfg) do db2_all "<<+%1< db2ckmig <dbname> -l /tmp/db2ckmig.log.%1"
On linux/unix, you likely need to script a while loop through a scan of the db2nodes.cfg file using shell or perl, in order to get a list of partitions, and then execute the db2_all using those partition numbers as shown in the above windows example with %1.
Best regards,
