Re: genoncfg utility - onconfig file not generated

Date: Friday, 3 July 2009, at 6:26 a.m.

In Response To: Re: genoncfg utility - onconfig file not generated (PAUL-JOHN TO)

Hi Paul,

Thanks for your reply, Along side deling with the IDS 11.50 FC4 crash issue i restore the instance and started working with the genoncfg utility with the following parameters just to start and get onconfig file in my local directory

cpus 8
memory 16384 m
connection name lt3 onsoctcp 1772
servernum 3
oltp_connections 100
dss_connections 10
disk /db2/informix/dbs/rootdbs 0 k 10000 m
directive one_crit

And nice to see a onconfig file was generated in my local directory.

I was going through the parameters configured by genoncfg utility for me untill i saw the NETTYPE parameter generated by genoncfg utility in the onconfig file.

> cat onconfig |grep ^NETTYPE
NETTYPE onsoctcp,1,150,CPU

CPU with onsoctcp ???

I checked for the onconfig.std file and my onconfig.lt3 file as well

> cat onconfig.std |grep ^NETTYPE
NETTYPE ipcshm,1,50,CPU

> cat onconfig.lt3 |grep ^NETTYPE
NETTYPE soctcp,4,250,NET

but could not see any combination of tcp and CPU which the genoncfg has generated in onconfig file.

Have you seen any thing alike?

Thanks again for your reply,

When configuring the system with a high number of users and CPUs, 1 GB on a single partition might not be sufficient for dbspaces, logs, and data. If the utility wants to allocate 900 MB for physical logs, there will only be 100 MB left over for logical logs and data. There are two solutions to this:

1) If your system has more than one physical disk, add more disks to the parameter file. For example, if /db3 were a mount point for an additional disk or partition, and you want to allocate 4 GB to this instance, you could have two disk lines in the parameter file, and genoncfg would decide where the physical, logical logs would reside.

disk /db2/informix/dbs/rootdbs 0 k 1000 m
disk /db3/informix/dbs/dbsp001 0 k 4000 m

2) Add the one_crit directive to the parameter file, as follows:

directive one_crit

This forces your physical logs, logical logs, and data to all reside in the root dbspace. If you get an error saying that more space is needed, you'll also want to increase the disk space allocation in the parameter file.

Hope this helps. Best of luck!



IDS 11.50.FC4 on Solaris 10

I was trying to generate a customized config file using the genoncfg utility

$:/export/home/vikas>cat con
cpus 8
memory 16384 m
connection name test onsoctcp 9088
servernum 3
oltp_connections 1000
dss_connections 10
disk /db2/informix/dbs/rootdbs 0 k 1000 m

$:/export/home/vikas> genoncfg con
Opening /opt/informix/ids-11.50.FC4/etc/IIF-cr...
Configuring a 64-bit server.
Measuring read speed /db2/informix/dbs/rootdbs...
Measuring write speed /db2/informix/dbs/rootdbs...
Physical Log size 900Mb is too small

I dont know if the genoncfg utility has runned sucessfully as there is not "onconfig" file generated in the working directoy.

Did i miss anything?
