I was trying to install EM13 v4 and I got the following error:

I’m using Oracle 19c as repository database. The solution for this is:

alter system set "_allow_insert_with_update_check"=true scope=both;
alter system set session_cached_cursors=200 scope=spfile;
alter system set sga_target=800M scope=both;
alter system set pga_aggregate_target=450M scope=both;
alter system set "_optimizer_nlj_hj_adaptive_join"= FALSE scope=both sid='*';
alter system set "_optimizer_strans_adaptive_pruning" = FALSE scope=both sid='*';
alter system set "_px_adaptive_dist_method" = OFF scope=both sid='*';
alter system set "_sql_plan_directive_mgmt_control" = 0 scope=both sid='*';
alter system set "_optimizer_dsdir_usage_control" = 0 scope=both sid='*';
alter system set "_optimizer_use_feedback" = FALSE scope=both sid='*';
alter system set "_optimizer_gather_feedback" = FALSE scope=both sid='*';
alter system set "_optimizer_performance_feedback" = OFF scope=both sid='*';

And restart the database 🙂
