I need to use DBAdapter with the feature of merger and without PrimaryKey
I have a FTPAdapter that gets a file from the server, but the file is not a primary key. It's only has a column with the type of UNIQUE constraint. How can I use the merge without primary key feature. The primary is generated by sequence and relaxation. For example, the file is not a primary keyIn fact, you need an unique identifier, primary key not exactly. When you use the db adapter Wizard you will be asked on the primary key when the wizard did not by itself. Simply choose the necessary columns (those unique key).
Primary keys must be produced by sequence, they can be passed a value as well or generated otherwise (in sequence). How it will be managed in TopLink characteristics of the created db adapter can be found. You can change the sequencing method, manipulate columns and constraints and so on.

What could I do?Hello
You can use the analytic LAST_VALUE function to get the last day of work before each date into your table. It will be the same as the current day for every day of work.
Do it a self-join to combine each current line (c) with the last day of work (l):WITH got_last_work_day AS ( SELECT dt, type, rate , LAST_VALUE ( CASE WHEN type IS NOT NULL THEN dt END IGNORE NULLS ) OVER (ORDER BY dt) AS last_work_day FROM table_x ) SELECT c.dt, l.type, l.rate FROM got_last_work_day c JOIN got_last_work_day l ON ( c.dt = l.dt AND c.type = l.type ) OR ( c.last_work_day = l.dt AND c.type IS NULL ) ORDER BY c.dt , l.type ;
Among other things, I guess that the type is NULL if (and only if) the line represents a holiday or weekend, and that the combination (dt, type) is uniuqe.

Need help - Cisco ASA with the power of fire
Hello
Currently, we use asa 5510 without function of firepower. Our goal is to publish web servers and microsoft lync with reverse proxy method. control internet traffic, apply extensions individual file not to download, management of bandwidth etc.
Is it possible if we add firepower on asa 5510... Please guide me... Thank you
Power of fire must be installed on the new series X of the SAA. 5512 x, x 5515, 5525 x, etc.
If you have a 5510, you probably want a 5512 x with an SSD. Cisco has beams of firepower include the ASAx with SSD and the license of firepower.
Adds that you must also Firesight management software, and there is a license bundle of 2 camera for under $ 500 that you can install on VMWare.
Firepower is not reverse proxy, it's transparent online packages, analysis and filtering by URL / Application / and threat mitigation.
If you want a reverse proxy, you should look into Microsoft ISA server or a Proxy Server reverse dedicated Web. Cisco gave its product Web Director, who has done this function.
You can host Web sites behind a firewall of ASA without proxy reverse. And the ASA has an inspection of the request for HTTP traffic, responsible for watching HTTP requests. The firepower to the ASA system also has specific signatures that monitor traffic to the web servers and prevent specific vulnerabilities that are known on those servers, so if that is what you want the Reverse Proxy for, then the power of fire module would probably cover your needs.
Don't forget that until the next quarter firepower system has no decryption on the box, and you might want to wait that the feature is released and put in place, so that you know what size firewall you need protect your network with the SSL decryption. I believe that the ASA5512x is testing at 75 Mbps stream decrypted via the fire power module, which is about half of what was before CX, then you could use the sizing numbers CX and extrapolate until Cisco releases official decryption numbers.

Text messages sent with an email address from a touch ipod duplicated on a second ipod touch using a different email address, but the two ipods are controlled by a parent with the same apple ID and password. This has happened recently. My two girls have used their respective ipods and texting, without their messages of duplication for each of the other ipods for more than a year. Somehow recently, both addresses seem to be synced with them or something, so that both see each and other messages. I've recently updated two ipods, iTunes on my computer--not the cloud and added music for two ipods, but has not changed anything by email email settings or message I know. Help, please!
