Let's start with some basic info.
- what commands does your SP generate and/or execute ?
- how big is the table that you're collecting statistics on ?
SELECT SUM(CURRENTPERM) FROM DBC.TABLESIZE WHERE DATABASENAME = 'name of database' AND TABLENAME = 'name of table';
- how many columns/indexes are statistics being collected on ?
HELP STATISTICS 'name of database'.'name of table';
- what release of Teradata are you using ?
SELECT * FROM DBC.DBCINFO;
Collecting statistics on a column often requires a full table scan (FTS). If it takes 30 minutes to do an FTS and you're collecting stats on 18 columns that will take about 9 hours.
