Omni-Patient HealthViews relies on a Hash64 function to create unique keys for the tables in the Omni-Patient HealthViews schema. In addition, the Hash64 function is used to create integer values for fields that are character strings in Omni-Patient. Joining integer fields provides improved performance than joining character strings.
The Hash64 function code is contained in the ibi_functions.so file. A system administrator who has the required authorization, must place the ibi_functions.so file in a known location (the default is /opt/pgsql) and set permissions to 755 (readable to all, executable by all).
A shell script (register.sh) is used to install the Hash64 function. Execute this script by typing the following command:
./register.sh [database_name]
where:
Is the name of the database where you want to install the Hash64 function.
Note: Only a system administrator who has the required authorization must perform the steps described in this section.
