1) Why transactions don't work when remote connection is in use? Tutorial
says its READ COMMITTED, so it should work.
2) How to check in console if something has changed in the database after
program execution?
In console i checked
orientdb {db}> select from #12:0
----+-----+--------+-------
# |@RID |@version|value
----+-----+--------+-------
0 |#12:0|21 |22
----+-----+--------+-------
And in Java program i I do a transaction:
ODatabaseDocumentTx db = new ODatabaseDocumentTx("remote:localhost/db").open
("admin", "admin");
db.begin(TXTYPE.OPTIMISTIC);
db.command(new OCommandSQL("UPDATE #12:0 set value='1'")).execute();
db.rollback();
in console again:
orientdb {db}> select from #12:0
----+-----+--------+-------
# |@RID |@version|value
----+-----+--------+-------
0 |#12:0|21 |22
----+-----+--------+-------
but after disconnect and connect again
orientdb {db}> select from #12:0
----+-----+--------+-------
# |@RID |@version|value
----+-----+--------+-------
0 |#12:0|22 |1
----+-----+--------+-------
When using 'plocal' instead 'remote' transaction works, but still need to
disconnect console and connect again to check if something has changed. Why?
Best regards
Tomek
