Re: [Dhis2-users] Possibility of creating non numerical UID prefixes in tracker capture

[Lars Helge Øverland]

Hi Aimee,

Isaiah is right re the UID format and you can find the docs here:

https://docs.dhis2.org/master/en/developer/html/webapi_system_resource.html#d0e11354

Note that the number of possible UID combinations are 5.2 x 10^19, or about
50 million trillion, so I would perhaps rather focus on generating properly
randomized UIDs and not worry so much about collisions.

best regards,

Lars

Re: [Dhis2-users] Possibility of creating non numerical UID prefixes in tracker capture

Hi Aimee,

What is the length of the UIDs? The dhis2 accepts UID length of 11 and can
accept any other types (letters and numbers) so long as the first one is a
letter.

If you want to avoid duplication of UID, the easiest way is by generating
them yourself using other tools or languages.
See the following example on UID generation.

Thank you.

Greetings all,
In Zambia we are investigating the possibility of having sub instances of
tracker capture that feed into a main instance, but we want to avoid the
issue of duplicate UIDs coming from the sub instances. We were hoping to
add a prefix onto the automatic UID generation - such as NG###, where
the prefix "NG" remains consistent and the numbers are automatically
generated. We've experimented with the UID options and the system does not
accept this pattern. Has anyone successfully done this before or have any

[Dhis2-users] Possibility of creating non numerical UID prefixes in tracker capture

[Aimee Edmondo]

Greetings all,
In Zambia we are investigating the possibility of having sub instances of
tracker capture that feed into a main instance, but we want to avoid the
issue of duplicate UIDs coming from the sub instances. We were hoping to
add a prefix onto the automatic UID generation - such as NG###, where
the prefix "NG" remains consistent and the numbers are automatically
generated. We've experimented with the UID options and the system does not
accept this pattern. Has anyone successfully done this before or have any
ideas as to how to do this?
