ChorusOS 4.0 Introduction

RDBS Configuration and Usage

If RDBS is started without any parameters it will connect, by default, to the first target available on the DebugServer. However, you can specify a target name on the command-line provided the name you use is registered with the DebugServer.

Note -

This name is unrelated to the name under which the target might be known on the TCP/IP network (through another connection). It only identifies the serial line connecting the target with the DebugServer.

A complete set of command-line parameters are documented in rdbs(1CC).

Several RDBS servers may be run on one machine to debug several targets, provided you define a different slot for each server.

Information about what targets are available to XRAY is held in the file chorusos.brd. There are four columns: the machine names where RDBS executes are specified in the first column, slot numbers are specified in the second column, and the last two columns are for comments. XRAY interprets integer values between 0 and 25 in the second column as slot numbers and larger values as TCP/IP port numbers, and will adapt its connection to the server accordingly.

Here is an example chorusos.brd file:

         rdbshost      0     "i386"  "System debug of target-i386"
         rdbshost      1     "ppc"   "System debug of target-ppc"

The entries specify that two copies of RDBS will run on the rdbshost machine (a Solaris workstation): one on slot 0, configured to debug the target-i386 target, and another on slot 1, configured to debug the target-ppc target.

Note -

The name and port number specified in chorusos.brd have different meanings:
