Re: installing DBD-Informix on fedora 6





I did have ipv6 switched on, so I tried turning it off but got the same error. I am going to reinstall the fedora server, without ipv6 this time and try it again.

can i ask does anyone have it working properly on fedora6 ?
if so, can you let me know if you did it the same way as i am trying?


I asked on another mailing list (linux@xxxxxxxx - the International Informix
User Group) and got at least a couple of positive responses.

One of the answers I got was that maybe GCC 4.1.1 has issues with ESQL/C.
I've got GCC 4.1.0 on my (old, slow) Sun Ultra 10 (1 CPU @ 333 MHz, 256 MB
RAM) and haven't noticed problems there; I'm compiling GCC 4.1.1 as I type
(into Stage2 comparison). I'll know whether that's a platform independent
part of the problem - are you actually using GCC 4.1.1 in the first place?

There was also mention that error 107 was something like 'end point not
available' - maybe indicating a networking error -- I'm drafting this in a
different gmail account from the one that gets the IIUG mailing lists so I
can't see the exact message.

I am inclined to agree with Tielman's assessment that the problem is as
likely to be on the database server as on the client, or maybe in the
networking in between the two. Presumably, you are satisfied that the DB
server is operational and can be reached from other machines without
problems.

Are you using IPv6 by any chance?

this is what I do on fedora 4

perl -MCPAN -e 'install Bundle::DBI'
groupadd -g 300 informix
useradd -u 200 -g 300 informix
source /etc/profile.d/informix.sh - see below for this files content
vi /etc/services - i add "sqlexec 1526/tcp informix" at the bottom
mkdir /opt/informix
chown informix.informix /opt/informix/
cd /opt/informix/
tar xvf clientsdk.2.90.UC2.LINUX.tar
cd clientsdk.2.90.UC2.LINUX.tar
./install_rpm
cd
tar xvzf DBD-Informix-2005.02.tar.gz
cp /opt/informix/etc/sqlhosts.std /opt/informix/etc/sqlhosts
vi /opt/informix/etc/sqlhosts - i add the db server here
perl rmautoinst.pl Makefile.PL | perl -
make
make install



cat /etc/profile.d/informix.sh
export INFORMIXDIR="/opt/informix"
export INFORMIXSERVER=pmuk2

no i dont see anything from that server when running the esqltest.
but
on the client i can telnet to the server on port 1526 as the user

i have stopped iptables and ip6tables on the client

can you snoop on the server to see if any packets reach the interface
at all when running esqltest?

there is some stuff that reaches it :-
[...snip...]
which seems to be referring to checking the hostnames?
hmmail2.uk1.bibliotech.net is the client (running fedora 6) and
dbpmuk2.uk1.bibliotech.net is the db server

Can you do "CREATE TABLE dbd_ix_esqltest (Col01 INTEGER NOT NULL);"
from dbaccess on the server in the stores database as the appropriate
user?

yes


This is a key issue (connecting with DB-Access on the server
machine). The
error 107 (discussed in previous emails in this thread) has me a bit
puzzled. Does Fedora Core 6 have an error value (from errno.h) for
107? If
so, does the associated message drop any hints? Taken at face value, it
appears that someone has the database locked in exclusive mode (though
I'd
like to think the error would say that more clearly). Did the process
(session) that created the database complete yet? Classically, you get
exclusive access when you create a database, up until you terminate the
session that created the DB.

When you connect using DB-Access, you are using the same server name and
sqlhosts values; you aren't suddenly switching to shared memory
connections
or anything like that?

You're using CSDK 2.90.UC2; that's good. Close enough to the most recent
version that it is unlikely to be the cause of the trouble.

You seem to be connecting to IDS as either root or informix - frankly,
you
should do neither. Treat them both with extreme caution - they are just
about equally powerful with respect to IDS. I never do things like
building
DBD::Informix as either informix or root; I'd find (or create) another
user
to do the work as. If I actually needed to install DBD::Informix as
root,
I'd use the privileges then, but only then.
