Hi Shiva,
As an aside from your real question on the LOGGING issue, may I ask the specific reason for configuring INITRANS? I know what INITRANS is for, so that is not my question. But with Automatic Segment Space Management in Oracle 9i and up, Oracle should be (in theory) automatically managing the number of ITL slots in the block. In fact, I think the docs state that any configuration of INITRANS will be ignored. Are you not using ASSM for the tablespaces in question? Or have you had issues with ITL waits even with ASSM configured in the tablespaces? Just curious :)

Tablespace logging level takes precedence if no explicit option is provided. check the tablespace level settings for the new partitions and do an alter tablespace logging to change that behaviour
