1. In 2014 we used a Base SAS92 program running on a WindowsXP PC to use a local Adabas ODBC driver to read Adabas D tables (version 15.01.07.21) on a Windows server. It ran cleanly and efficiently. 2. In 2015 we used a Base SAS94 program running on a Red Hat Linux6.5 machine to use an Adabas ODBC driver to read Adabas D tables (version 15.01.07.21) on a Windows server. It ran very inefficiently: the unwanted Adabas D database utility "updatestatistics" was executed for every one of the 59 Adabas D tables. The Adabas ODBC driver resides on our SAS PC File Server Windows 2008 r2sp1 machine. 3. The technically advanced SoftwareAG group in Europe state that it is not an Adabas D problem. It is a SAS problem. Something has changed in the way the SAS program connects to, or interrogates, the Adabas D database. 4. We have tried many different investigations including checking DSN related SQL trace logs. We cannot find any reason for SAS94 to trigger the "updatestatistics" executable. Any ideas gratefully received. 25.11.2015.
