Retrieving PTF cover letters using SQL

In preparation for forthcoming annual audits I was asked if there was a way to be download the PTF cover letters for all the PTFs that had been applied in 2023 in a format that could be searched?

In previous years all of the PTF cover letters were printed out and retained. If anyone had a question about whether a PTF was applied to a certain feature the printed letters were manually searched. This could take a long time.

Fortunately the last Technology Refreshes. IBM i 7.5 TR3 and 7.4 TR9, comes with a something I can use. Within them is a new Db2 for i, SQL, table function to View PTF cover letters, PTF_COVER_LETTER. If I can view a cover letter I can also insert it into a table. Which is a lot better than using the output from Display PTF Cover Letter command, DSPPTFCVR.

Using SQL to ping remote servers

Included as part of the recent Technology Refreshes, IBM i TR3 and 7.4 TR9, comes a new Db2 for i, or SQL, table function that allows me to ping a remote server and get the result in one row.

The PING table function has a number of parameters you can use with it:

  1. REMOTE_SYSTEM:  This is where I would use the name of the remote server. There is a default value of *INTNETADR, which notifies the table function I am wanting to ping with the IP address.
  2. REMOTE_IP_ADDRESS:  The remote server's IP address. If REMOTE_SYSTEM is not *INTNETADR then this parameter is ignored.
  3. ADDRESS_VERSION_FORMAT:  Which IP address format to use. Allowed values are *IP4, *IP6, and *CALC which is the default.
  4. NUMBER_OF_PACKETS_TO_SEND:  Number of packets to send. Allowed range is 1-999, default is 5.
  5. PACKET_LENGTH_TO_SEND:  Length of the packet to send. Allowed range is 8 – 65500, 256 is the default.
  6. WAIT_TIME:  Number of seconds to wait for the return packet. Allowed range is 1 – 120, default is 1.
  7. LOCAL_IP_ADDRESS:  Local internet address that the outbound packets use. Can be an IP4 or IP6 address, or default which is *ANY.

New View for listing jobs within job queues

Included as part of the recent Technology Refreshes, IBM i TR3 and 7.4 TR9, comes a new Db2 for i, or SQL, View that will return all the jobs that are submitted to job queues.

I have written in the past about how to find a job that has been submitted to batch. This new View makes it much easier to find this information.

I have a couple of examples of the kind of information I want to find about submitted jobs. But before I talk about those I recommend that you run the following statement to see what information is returned. As there is, IMHO, a lot of useful information in the columns of this View.
