changing bad location for root chunk

I've inherited an IDS 7.31 UD4 database running on AIX 4.3.3 ML10, which unfortunately was set up 6 years ago with chunks pointing directly (no symlinks) to the block devices instead of the character-special devices. This includes the root chunk. We are working with our application vendor's DBA to move our badly-interleaved tables to separate dbspaces that are correctly defined with symlinks, raw disk, properly-sized extents, etc. My question is: is there a safe way to get the root chunk re-defined to point to the character-special device instead of the block device, and better yet, with a symlink? A secondary question: is it worth the bother to change it now? Below are a few lines from onstat -d: Chunks address chk/dbs offset size free bpages flags pathname 60052210 1 1 125 62500 48881 PO- /dev/root_chunk Peter Link University of Michigan Health System Ann Arbor, MI USA

Yep, I'd love to see what happens if your OS ever rebuilds /dev for some reason! > > > Below are a few lines from onstat -d: > Chunks > > address chk/dbs offset size free bpages flags pathname > > 60052210 1 1 125 62500 48881 PO- > /dev/root_chunk > > > Peter Link > University of Michigan Health System > Ann Arbor, MI USA
