I am working with db2v8.2.2 AIX 5.2.

I am using Task Centre for running some scripts, db2 export statement be terminated after the size of IXF file becomes 1073741312 byte and I get MSG DISK FULL, actually none of disk is full, I change the values for ULIMITE userid to unlimite but still does not work, when I run the script without task center it work fine,

is it possible task center has some limitation in file size? Please HELP
