(You've recommended to deactivate all databases before importing but in my case it is impossible). I follow the steps as you have duscussed: I first create new database and it must be open in order to import the ecoinvent database. Processor: Intel(R) Core(RM) i7-4770 CPU GHz 3.40 Ghz I am aware that the speed depend on the computer and here are the parameters of mine: I tried importing the smaller database first and it takes around 15-20 minutes. It happens for seconds on the youtube video ( ) but it takes a lot of time on my computer and for the lci database it doesn't work and I should forcefully close openLCA to cancel the process, just like you have discussed here. I have already read the comments above and saw the videos on youtube and I found out that I should first import the system process database (lci) as it is larger and then I can import the unit process database which is smaller. I apologize to bring this topic up again but I have similar issues with prolonged time for import of zolca databases (namely ecoinvent) in openLCA 1.6. It’s been running for more than 7h on a relatively “quick” computer (see specs above).ĪllFigs.JPG (122.88 KiB) Viewed 19808 times Instead of selecting “Existing database” (which would be repeating something that had not worked), I selected “From exported zolca file” and then selected “ecoinvent3_1_cutoff.zolca” (Fig.7). This unfortunately imports in a separate database (Fig.5b).Ħ) I therefore used the “other” Import function (Fig.6a, Fig6b), as I did yesterday. The database imported fine in just a few minutes.ģ) I activated the imported database (Fig.3).Ĥ) I moved all processes to a subfolder called “_LCI” to be able to distinguish these from UPs in the future (Fig.4a and Fig.4b)ĥ) I used the “same” import database function and selected the ecoinvent3_1_cutoff.zolca database (Fig.5a). So I tried the procedure you outlined (Figures are in the attached picture)Ģ) I imported the ecoinvent3_1_cutoff_lci database using the “Import database” function (Fig.2a and Fig.2b).

Indeed, the procedure I tried did not yield any fruits: all the process categories from the “importing” database (ecoinvent3_1_cutoff) were copied into the “receiving” database (ecoinvent3_1_cutoff_lci), but no process data was copied. Has anyone else succeeded in merging the databases? How long did it take you? I know that merges can take a long time, but do these times seem OK given the task and my system? I will leave it running for another 8 hours - then I need to turn off my computer. The process has been going on for 12 hours now.

Import took about 5 minutes.Ħ-Activated “ecoinvent3_1_cutoff_lci.zolca”ħ-Moved all processes to a folder (child of process folder) called “LCI” to be able to distinguish these datasets from the UP datasets I wanted to import to have a merged databaseĨ-Clicked "Import" and selected “existing database”, then “ecoinvent3_1_cutoff.zolca” from drop-down menu. Import took about 2 seconds.ĥ-Repeated 3-4 for “ecoinvent3_1_cutoff_lci.zolca”. Has anyone else been able to import these databases?ĭid you find a difference in import time between an import in an "empty" database (with only reference values) and a database that already contained process data?īased on your answer, here is what I did:Ġ-Deleted all existing databases (I wanted to start with a "clean slate")ġ-Created an “empty” database with reference dataģ-Right clicked and selected “import database”Ĥ-Selected “ecoinvent3_1_cutoff.zolca”. OpenLCA seems to consume about 20% of my CPU and 25% of my memory during import.
