OpenVMS Enterprise Option Configuration
TCP/IP Stack Optimization
The configuration of the TCP/IP stack can affect client agent performance.
Typically, the TCP Send and Receive quotas are set to 4096. Set these values
to the largest value allowed by the specific stack installed on the OpenVMS
system.
Trace Levels for the OpenVMS Enterprise Option
Occasionally, based on instructions from Computer Associates Technical
Support, you may need to change the level of activity that is logged for the
OpenVMS Enterprise Option. Because tracing levels can affect backup
performance, do not change the values unless you receive specific instructions
from Computer Associates Technical Support.
