Topic: Commit Write NoWait

Day kind!

Whether Can at "commit write nowait" , from time to time, not to be fixed record? If yes, whether that can be seen, found somewhere it this record, for . The period?
Approximate type of a packet:
[spoiler]

package body logs is pragma serially_reusable;
procedure errs (msg IN VARCHAR2) is PRAGMA AUTONOMOUS_TRANSACTION;
begin
insert into errs (mess) values (msg);
COMMIT WRITE NOWAIT;
end errs;
procedure ins1 (vs1 IN VARCHAR2) is PRAGMA AUTONOMOUS_TRANSACTION;
begin
insert into ins1 (str) values (vs1);
COMMIT WRITE NOWAIT;
end ins1;
procedure ins2 (vs2 IN VARCHAR2) is PRAGMA AUTONOMOUS_TRANSACTION;
begin
insert into ins2 (str) values (vs2);
COMMIT WRITE NOWAIT;
end ins2;
procedure parse (vs IN VARCHAR2) is PRAGMA AUTONOMOUS_TRANSACTION;
begin
ins1 (vs); - record is
-- ...
ins2 (vs); - records are not present
exception when others then errs (msg); - in broad gulls it is empty
end parse;
...

[/spoiler] p.s. At repeated "running" with the initial data, record correctly registered in both tables.

cannot, if "basis" during this moment "did not fall".

Broad gulls, happens, are not written.

Barabashek is not present, and an error, as usual, somewhere in 17th line.
P.S. With  not search?

Asynchronous Commit
[spoiler] Note that the specification of the NOWAIT and BATCH options allows a small window of vulnerability in which Oracle Database can roll back a transaction that your application view as committed. Your application must be able to tolerate the following scenarios:
1) The database host crashes, which causes the database to lose redo that was buffered but not yet written to the online redo logs.
2) A file I/O problem prevents log writer from writing buffered redo to disk. If the redo logs are not multiplexed, then the commit is lost.
WARNING SUMMARY:
The COMMIT NOWAIT feature also has serious implications for database consistency in the event of an instance crash or hardware fault occurring while COMMIT NOWAIT is enabled. Backup and recovery strategies must be up to date and readily available if the COMMIT NOWAIT feature is enabled due to the nature of the affects during failures. [/spoiler]

Thanks, times "fall down" ORA-06519 (rollback back for not complete independent transaction is fulfilled) on the operator return . Only it is not clear why, there can be a business in reset of variables of a packet if the packet is simultaneously used by several tens clients?
vs = d038163220180103F301000000000000000953486:24

procedure parse (vs IN VARCHAR2) is PRAGMA AUTONOMOUS_TRANSACTION;
n number (3);
i number (1);
begin
ins1 (vs); - record is
n: = length (vs);
if n <64 then i: = 1;
