Starting HDR and using only level-0 backup vs (currently not implemented) using level-0 with incremental backups

For physical restore secondary of HDR, level-0 must be using. If you are using incremental backups from primary for physical restore on secondary, you get the error on secondary IDS in online.log:

...
11:55:36 DR: new type = secondary, primary server name = hdr_lo
11:55:36 DR: Trying to connect to primary server = hdr_lo
11:55:38 DR: Secondary server restored from a non level-0 archive - aborting
11:55:39 IBM Informix Dynamic Server Stopped.
...

Why IBM does not fix this behavior for possibility using incremental backups for physical restore secondary HDR?

From one article to another of documentation we look: PAM supported on all 32bit platform, on 64bit platform PAM does not supported on AIX and HP-UX :(

Good news for admins and users who working with IDS on AIX: IDS 10.00.FC5W3 (64bit IDS for AIX) does support PAM (with CSDK 9.40TC6)
