Receiving time out errors when harvesting CONTENTdm OAI repository
Symptom
- Requests to our CONTENTdm OAI-PMH repository time out when attempting harvests.
Applies to
- CONTENTdm
Resolution
CONTENTdm OAI repositories are a PHP-based service, and including specific criteria will considerably slow down the process, even causing time-out failures. Requests like the following are often subject to failure: http://OAIbaseURL.org/oai/oai.php?verb=ListRecords&metadataPrefix=oai_qdc&from=YYYY-MM-DD
When placing requests, only place requests for the full repository: http://OAIbaseURL.org/oai/oai.php?verb=ListRecords&metadataPrefix=oai_qdc
The only workaround for time-out failures is to request the full repository and post-process for the desired results.
