RE: IDS on Compaq/Digital Unix
Posted in 2000
Our specs are as follows:
DEQ 4100 5/533 3-CPU server with a couple RAID sets
Tru64 UNIX 4.0F (No patch kits installed... yet)
IDS 7.31.FC2-1
4GL 7.20.UE1
RDS 7.20.UE1
ISQL 7.20.UE1
4GL ID 7.20.UE1
D4GL 3.00.UC1
ESQL/C 7.24.FC6
Client SDK 2.30 and 2.40
The software operates nicely but we have had some problems.
We got CSDK 2.30 and 2.40 because it was required to develop D4GL
applications. However, there is an incompatibility between D4GL 3.00 and
CSDK 2.30 and 2.40 that causes it to fail to complie applications
successfully. That's why we had to get ESQL/C 7.24.FC6; this works well
with D4GL 3.00. There's an open case with Informix Tech Support (ITS)
currently looking at it, but I don't expect a solution soon.
Also, we exposed a bug with fglform. Within the ATTRIBUTES section of a .per
file, we can specify formatting using the DISPLAY LIKE and/or FORMAT
attributes. In our development environment, for fields of type DATE
(whether they're FORMONLY fields or linked to a table.column that is
datatype DATE), if the DISPLAY LIKE attribute occurs after the FORMAT
attribute, the FORMAT attribute's value is not used. Instead, the field
displays using the setting of the $DBDATE variable or, if it is not set, the
format "mm/dd/yyyy". This is so even if there are values stored in the
syscolatt table for the DISPLAY LIKE column (i.e. it doesn't even seem to be
pulling formatting defaults from syscolatt). This is also the subject of an
open case with ITS.
Also, there's a problem with D4GL's handling of TEXT data placement in
reports with the PRINT COLUMN xx, <TEXT_VAR> WRAP MARGIN YY statement. Our
application vendor has an open case with ITS on this and also has posted
messages on it within this list. We don't expect any solution soon but
would really like to get one (hint! hint! Informix!).
I also experienced two problems with IDS that I haven't reported to ITS yet.
The first is that for some reason a cold restore of ontape -r doesn't work;
it gave me a tape error and then hung. However, using the same tape, I was
able to successfully complete a warm restore of two dbspaces and a
blobspace. I have to re-test this on another server. The second problem is
that if I issue an onstat -z conmmand to zero the onstat counters, the
majority of the onstat -p (and some others) forever remain zero until I
bounce the engine. So I've stopped zeroing my counters (used to do it
everyday to get daily comparisons).
I tried playing around with PDQ and twice I got engine panics that aborted
the instance. I'm running a mixed OLTP/DSS environment (more OLTP, but at
month-end many two departments need to run large reports). I tried allowing
selected users to use PDQ and I ran into problems, so I turned it back off.
I now operate with everyone having PDQPRIORITY=1 so they at least get
parallel scans. I haven't looked at this any further since then (I'm also
experimenting with the CPUVP:Pysical Processor ratio; rught now I have 3
Physical CPUs but 6 CPUVP's and the database normally works fine, but I
don't know if this contributed to the PDQ panic).
Other than that, we're fine. I'm now concentrating on developing proper
database security and ODBC access for reporting and will look to get into VB
client/server development within this quarter. I'm impressed with our
platform, but to be honest I haven't had much experience with others to
compare (played with SCO and HPUX but not to the depth of Tru64). I've also
been playing with Informix for six years now, but again I have nothing to
compare it with (I've just started to delve into SQL Server and ORACLE;
gimme two more years). I've been told that our platform is one of the most
secure platforms out-of-the-box and with each OS upgrade it becomes more
user-friendly, but it's not perfect.

Subject: IDS on Compaq/Digital Unix
I may be in a position of bringing up IDS 7.31 on a Compaq/Digital
UNIX
machine. I rarely see posts from people running these machines. Is that
because: 1) Informix runs so well under Compaq/Digital that no ever has any
problems? 2) There are very few installations of Informix on these
machines? 3) People who run Informix on these machines are naturally humble
and don't like to draw attention to themselves?
If anyone has some insight about running Informix on Compaq under
True64
(I hope that is the correct UNIX) I would appreciate it. Are there any
particular levels of operating system we should be at? Any patches that
need to be applied? Any Informix bugs that show up under this operating
system? Thanks for the information.
