| Description |
|
Only one instance of MODOAIPMH should be deployed (as sticky session cannot be done with current infrastructure). In terms of performance and availability there will be no issues with having one instance of MODOAIPMH module. The underlying business case is the following: Expected result: Actual result: Note: Priority P2 is set for the issue after discussion with Anastasiia Zakharova, as it causes significant problems for OAI-PMH harvesting |

I can see how you could provide session stickiness between an outside client and edge-oai-pmh, but how can you provide that through to mod-oai-pmh, which is proxied by Okapi? Adam Dickmeiss – any thoughts? |

Only one instance of mod-oai-pmh was deployed instead of being clustered. This is a temporary solution, mod-oai-pmh should become stateless in future. |
