JNLBUFFTOOSM, Journal file buffer xxxx is less than minimum of database block size in 512 byte pages + 1 (yyyy)
MUPIP Warning: This indicates that a SET command with the JOURNAL qualifier failed because the BUFFER_SIZE=xxxx was inadequate to handle a database block. yyyy is the minimum buffer size permitted for the existing block size.
Action: Increase the BUFFER_SIZE so it contains at least one more page than the database block, that is, bytes divided by 512.
