Resolution:
This can be in most cases solved by changing Oracle settings.
Need to Set Oracle processes to 400, open_cursors to 1000 and sessions to 400.
Here is how it may be done:
Login as sqlplus aleph_dba/aleph_dba as sysdba


Issue the following commands:
SQL> alter system set open_cursors=1000 scope=both;
SQL> alter system set sessions=400 scope=spfile;
SQL> alter system set processes=400 scope=spfile;


Then do aleph_shutdown, restart Oracle (via util O), and aleph_startup.
