Specify Secure Remote Shell Command (DB2RSHCMD)

ÉlevéeNiveau 1Automatiséedb2

Description

The DB2RSHCMD registry varible specifies the remote shell command to use when starting remote database partitions and with the db2_all script to run utilities and commands on all database partitions. It is recommended that a value be used which encrypts the data sent between partitions, such as ssh. Passes when DB2RSHCMD is unset or points to ssh. Default: The default value is ssh. Run as the instance owner (or with sqllib/db2profile sourced) so the db2 CLP reads this instance's configuration.
