Re: Informix doesn`t start

In Response To: Re: Informix doesn`t start (NOS PIOTR)

That's good news. I've been on windows for a while,=20
and haven't seen this behaviour yet, but then I=20
skipped 11.5.

Once initialized, you can't change the size of the
initial chunk of rootdbs - this fellow:
ROOTSIZE 204800 # Size of root dbspace (Kbytes)=20
So leave that entry alone in your %ONCONFIG%.

You can add a second chunk to it, which is what
it looks like you were doing in your first email.

Run an "onstat -d" and see if you now have two
chunks in the rootdbs dbspace.
It would look something like:

Top section:
Dbspaces
address number flags fchunk nchunks pgsize flags =
owner name
2058746a8 3 0x40001 1 2 4096 =
N BA informix rootdbs

Bottom Section:
Chunks
address chunk/dbs offset size free bpages =
flags pathname
2058741d0 1 1 0 50000 29173 =
PO-B-D C:\IFMXDATA\ol_ids_1150_1\rootdbs_dat.000
205874ba0 2 1 0 100000 34947 =
PO-B-D C:\IFMXDATA\ol_ids_1150_1\rootdbs_dat.001

Your command was close the first time except:
onspaces -a rootdbs -p C:\IFMXDATA\ol_ids_1150_1 -o 402000 -s 5120

You needed to give it the name of a file, not a directory,
the -o 402000 is saying you want to offset by 402MB into the file
and the -s is the size you want to create it. 5MB isn't going to be =
worth the trouble.

You can actually use the same file that you used the first time =
(rootdbs_dat.000)=20
and offset it by 204800, - that way you don't have to create a second =
file, but it hides
what you have done from plain sight.

Something like this make more sense:
onspaces -a rootdbs -p C:\IFMXDATA\ol_ids_1150_1\rootdbs_dat.001 -o 0 -s =
512000

First, that file rootdbs_dat.001 must exist. And easy way to create it =
is to:
copy con rootdbs_dat.001
[CTRL-Z]

So you are copying from the keyboard to the file
and the first thing you type is [CTRL-Z] - the end of file
marker in DOS. That while create an empty file.

Merry Xmas.
