Hi,
ranchers,

i am facing a problem while applying locks on the oracle table.my intention is stop the accessing of table to other users, if the table is locked by one user.

for this i wrote the code as follows



after locking i inserted some data into table, after insertion i am not commiting it because if i commit,the lock will be release.next i am trying to insert data into that table from another system,actually the data don't insert.but data is inserted. how it is happening like that ??

in another scenario, if execute the locking query on the database directly then trying to insert into database through java application, at that time it is not giving permission to access table(in this case evrything is fine).

please guide me

thanks®ards,
nagaraju.

Try setting the transaction level using the connection object.

Example :

con.setTransactionIsolation(8);

The int values represents 0= TRANSACTION_NONE
1= TRANSACTION_READ_UNCOMMITTED
2=TRANSACTION_READ_COMMITTED
4=TRANSACTION_REPEATABLE_READ
8=TRANSACTION_SERIALIZABLE

8 should be a good option for you else you can use the values as per your need.

Do you commit the lock statement?
