OpenVMS Enterprise Option Configuration
56 Client Agents Guide
Configure Port Address
The default TCP and UDP port addresses are both 6050. The TCP port is used for
communication and data transfer between the cprocess and the client agent. CA
ARCserve Backup uses the UDP port to browse the hosts.
If you want to configure the TCP port or the UDP port, include the following
command in the bab$startup.com file:
DEFINE /SYSTEM ASO$PORT_NUMBER
nnnn
In this example, nnnn is the port number of the Backup Manager.
Important!
OpenVMS requires that both the UDP and TCP ports be assigned the
same port number.
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 CA Technical Support.
Level
Description
ASO$TRACE
This controls the trace depth of the client agent. Valid
values are -1 and 0 to 0xFFFFFFFF. Setting the
ASO$TRACE value to –1 logs the most detail.
ASO$TRACE_AST
This is a toggle. If defined, Asynchronous System Traps
(ASTs) are traced.
ASO$TRACE_IDENT
This is a formatting parameter. The recommended
value is between 0 and 5. The default is 3.
ASO$TRACE_DATA
This controls the number of bytes of each packet that is
logged. The range is unlimited and starts at 0. The
default is 300.
