This is either an internal deadlock, multiple running appliers using the same data, or someone manually changing data using this account.
User DBVREP, sid,serial#: 15,529,
Module/Action/ClientInfo: XID: 0005.01f.008c23da/start SCN: 8412318113/,
Last Call Elapsed Time 71, Event enq: TX – allocate ITL entry.
RBA: 0x00004a.0032b1ce.0021.2. SQL: update “SCOTT”.”EMPLOYEES”

Solution

The key in the error above is Event enq: TX – allocate ITL entry.

You need to increase the Inittrans on the table:

ALTER TABLE scott.employees INITTRANS 100;

However, remember that this would only take effect on new data blocks. You may have to move the table in order to have it take affect:

ALTER TABLE scott.employees MOVE INITTRANS 100;
