During purge partition, Customer experienced that it was taking very long time during swap partition step (1 hour++). The partition size is 300,000. Below are steps which we use to purge partition.
Note that we stopped at step#2 because it took too long.
a_online => true,
a_delete_before => sysdate + 1,
a_order_states => om_new_purge_pkg.v_al-0l_orders,
a_order_id_ge => null,
a_order_id_lt => 300001,
a_drop_empty_ptns => false);
During step#2, we observed that below statement was iteratively going through every single partition even though table is empty. OSM has a lot of sub partitions across many tables. This is suspected to be causing the slowness. Is there anything we can do to improve the time taken for purging partition process?
