Before you perform dumps and loads. you must configure the local and remote Backup Servers at start-up by providing the appropriate values for the system resources controlled by the command-line options. See the Utility Guide for a complete list of the command-line options.
If your system resources are not configured properly, the dump or load can fail. For example, a remote dump to greater than 25 stripes with the local and remote Backup Servers started with default configuration will fail because the maximum number of network connections that Backup Server can originate (specified by the -N option) is 25; however, by default the maximum number of server connections into the remote Backup Server (specified by the -C option) is 30.
To configure the system to use the higher stripe limitations, set the following operating system parameters:
Number of shared memory segments to which a process can attach.
Number of shared memory identifiers
Swap space
If these parameters are not configured properly, when a dump is started to (or a load is started from) a large number of stripes, the operation may abort because of lack of system resources. In this case, you receive a message that Backup Server could not create or attach to a shared memory segment and therefore the SYBMULTBUF processes are terminated.
