TEMPDBSPACE HELP

Posted By: Preetinder Dhaliwal

Hi,

We have an informix 4gl report ( does not create any tables
explicitly ) which has an order by clause on 7 to 8 fields. The record
being output to report is very big.

We have our DBSPACETEMP variable exported to
"DBSPACETEMP=ibs_tmpdbs1:ibs_tmpdbs2" , output of onstat -c and onstat
-d are attached( are text files).

When we run this report for lot of data, we get this error -
sqlca.sqlcode = -271 , ISAM ERROR CODE = -136 ( no more extents ).

The tempdbs spaces show enough space , and there are no tables
created within the program.

It looks like the default extent size used by informix to create
temp tables for sorting is not big enough. any way we can override
this ?

Also the problem occurs if I run the same report from two sessions.
Are they trying to use same informix temp table??

Rgds
Preetinder
