Hi Robert,
Thank you for your enquiry.
As you correctly stated, old versions of LMi, such as LMi 8.2B, used to require an exclusive lock on the Requisite PF or Table when a Dependent object such as LF is being installed.
I confirm that this requirement has been resolved in later versions.
LMi has been rebranded RDOi. The current version RDOi 10.2 offers the possibility to keep the above behaviour as is, or to allow the Dependent Object (LF) to be replaced even when the Requisite Object (PF) is locked by another application. This is facilitated by the Deployment Profile parameter “Install LF when requisite PF is locked”.
Copy File While Active (CFWA).
In addition, for customers with very small Deployment window, RDOi 10.2 offers the ability to "Copy File While Active" (CFWA). This feature allows the Deploy Install of a Requisite Object (PF or Table) having a large amount of data to be replaced in a very short duration. Thus minimal downtime impact on 24/7 Applications.
Please upgrade to RDOi 10.2 (or to RDOi 10.3 soon to be published) at your earliest convenience.
Further information on "Copy File While Active" (CFWA) is found here which also contains "Workflow", "Setup" and "Limitations".
I hope that you find this information useful.
Regards
Jay
