HI Brent,

( I had to move my post to a different place) .

To answer  to your advise I still have same issues in ASE  15.7 SP103 , the consumers options is been ignored and the DDL runs in serial mode, see more details bellow, please:

>create index idx1_file on mfs_files( archiveID, file_id ) with consumers=10, online

 

QUERY PLAN FOR STATEMENT 1 (at line 1).

 

 

    STEP 1

        The type of query is CREATE INDEX.

 

        TO TABLE

        mfs_files

        Using I/O Size 2 Kbytes for data pages.

 

(return status = 0)

ASE15.5 and ASE 15.7 index parallelism not been used

You can avoid locking the entire table during index creation by upgrading to 15.7 SP100 or higher and using the new "with online" option.  See: create index

 

15.7 SP100 also introduces a new configuration parameter "max utility parallel degree", which can also be the reason worker processes aren't used in 15.7 SP100 and higher.

 

Is it possible any of the 10 partitions is currently empty?
