> Dear,
>
> our investigations has lead to the first conclusion. The regular upload of
> (new) data increased the CKAN database table activity to a high number.
> Very lickely this causes the instability of the CKAN system.
>
> On our test system (a release 00.07.01) we activated the production dump.
> During the indexing (a process step required after changing the database in
> the back)
> the CKAN system halted. After emptying the activity table the indexing was
> restarted and it finished properly. After that we have run rdf2ckan with
> the latest zip you have provided.
> At this moment the EEA and SANCO zips passed. Currently a Eurostat zip is
> running.
>
> In the svn you find a script to clean the appropriate tables. This is a
> quick-win step towards having back a stable system.
>
>
> https://webgate.ec.europa.eu/publications/svn/ODP/trunk/ckan/management_scripts/ckan_clear_activity_table.sh
>
> Copy this script to $USERHOME/ckan_management and complete the necessary
> parameters. These are the same as for a CKAN backup. ****

>
> The script will first backup the table and afterwards empty the tables.
>
> The execution on our site costs +- 45 minutes and resulted in a file of
> 7.6 GB.
>
> After the script execution, you have to trigger for this time the
> reindexing of the database.
> In $USERHOME/ckan_management
>
>      ./ckan_reindex.sh
>
> (It  costs +- 1hour on our site)
>
> We keep you informed about the outcome of the Eurostat test.
>
> ps. I inserted the description of the new script also in the OM on section
> 7.10.
