Figure 20 SQL Startup Option Page

This Startup Option page provides a tab for each particular SQL instance. Clicking on a tab
displays the trace flags available for that particular SQL instance.

Trace flags are very sensitive to SQL server edition and versions. Only trace flags supported by
the SQL instance are shown on the page with status. Detailed description on each supported trace
flag is displayed on this page.

To change the status of an individual trace flag, select a new value from the drop down box and
click SET.

CAUTION:

Each trace flag covers a very specific field and requires certain conditions to work.

Caution should be used when turning a trace flag on or off.

Trace Flag 8048

Enable Trace flag 8048 (TF-8048) to use memory allocation at the CPU level in order to reduce
costs when you have too many CPUs per NUMA node.

Optimizations Pages
