OAI provider gives only part of set or no / slow responses
- Product: Aleph
- Product Version: 20, 21, 22, 23
- Relevant for Installation Type: Dedicated-Direct, Direct, Local, Total Care
Problem Symptoms:
Using OAI provider (URL syntax http://<server>/OAI-script?verb=ListRecords&...):
* Not all expected records are included
* Response is very slow
* No response at all
Cause:
"Old" OAI provider.
Resolution:
Implement "new "Publishing Based OAI Data Provider.pdf and use this provider instead of the "old" one.
Additional Information:
For explanation - in Aleph two OAI provider exist:
1) "Old" OAI provider (URL syntax http://<server>/OAI-script?verb=ListRecords&... ) If a customer has used this provider all the time and is happy with the results, it is fine.
2) "New" Publishing-Based OAI Data Provider (URL syntax http://<server>/OAI?verb=ListRecords&... ) was implemented: Publishing Based OAI Data Provider.pdf . It has much better performance and more stable.
The "old" OAI provider exists still in the programs for backward compatibility. It is using Z13 "on the fly"; therefore it is very slow and sometimes doesn't even response when you have large number of documents.
We strongly recommend the use of the publishing-based OAI provider.
