COMMIT FAILS

Question

i have a static commit function, defined in my dbInfo class.
public static void commitTransaction() {
f.show("start commit");
try {
f.show("1");
dba = sessionVideoDB.getDbAccess();
f.show("2");
dba.commitTransaction();
f.show("3");
catch(RowsetValidationException ex) {
f.show("dbInfo commitTrans rowsetvalidation exception");
f.show(ex);
catch(SQLException ex) {
f.show("dbInfo sql exception");
f.show(ex);
ex.printStackTrace();
catch(Exception ex) {
f.show(">>>exception");
ex.printStackTrace();
f.show("end commit");
the problem is that now and again it stalls on the dba.commitTransaction(); line, with no exception...
the output is as follows:
start commit
1
2
then nothing the application calling the commit function locks up.
ANY IDEAS......
any help would be most appreciated

Answer 1

Do you have Oracle enterprise manager? Look for blocking transactions. If no OEM, do select * from v$lock and try that.
Another possibility is that you have run out of archive log space.
There's many, many other possibilities... have you tried the exact same updates/inserts/deletes followed by a commit using SQL*Plus against the same database instance to assure that everything works?
Good Luck
