TurboIMAGE/XL Database Management System Reference Manual
Remote Databases
Locking remote database entities is the same as locking database entities
with the following exception. If the local system has a user-created
process structure, and each process is locking a remote database
independently, the programs must have Multiple RIN capability because
they are in the same job/session. The only effect using MR capability
has on the local system is that the rule prohibiting multiple DBLOCK
calls is not enforced. However, to access remote databases, each local
process must issue a separate REMOTE HELLO to ensure that it has a
corresponding process in the remote system.
The system does not force you to establish corresponding remote
processes, but failure to do so can result in the remote session being
suspended permanently which requires a remote system restart to recover.
CAUTION Hewlett-Packard does not accept responsibility for system
lockouts and deadlocks when Multiple RIN capability is in use
with TurboIMAGE/XL.
The following DBUTIL command can be useful in tracing deadlocks that
occur when CAP=MR is used.
