IFS breakdown objects by subdir.sql
Someone asked if you could count the stream file objects, by directory. This solution gets the job done and includes the total size count as well.
Number of objects in a directory
Spreadsheets and Emails with SQL & ACS.sql
In this Gist, I show how you can leverage ACS's jar that is shipped on your IBM i to do your bidding. In this case, we can automate the creation and downloading of a spreadsheet to an IFS file where the contents of the spreadsheet is controlled with an SQL query. After the spreadsheet is created in the IFS, we use SQL once more to email the spre…

Bringing order to the IFS.sql
This example picks on the IFS stream files found within and under the /tmp directory. How much gunk has been accumulated under /tmp and what can you do to manage it? A bit of SQL to the rescue. The IFS_OBJECT_STATISTICS() UDTF returns many elements of data for you to leverage for improved management of the IFS.
Objects in /tmp directory
TopN user storage report.sql
This example takes a previous example and extends it. The idea here is that you want to proactively manage user consumption of storage. For the top storage consumers, return a report that lists their largest objects (either in QSYS or IFS) and provide some contextual detail. This solution includes simple controls to allow the caller to specify t…
Storage
Object ownership by user - total report.sql
This gist combines several IBM i (SQL) Services to produce an easy to consume UDTF. Pass in a user name and you'll get back all the QSYS and IFS objects they own, ordered by size descending.
Object ownership
Generating spreadsheets with SQL.sql
In this working example, we establish an SQL table which contains the spreadsheets we'd like to have generated. Each row in the table includes the query that will supply the data for the spreadsheet, and the location in the IFS where the spreadsheet should reside. Further, a different procedure emails the spreadsheets to an interested consumer.

Protect the IFS root for *PUBLIC
When an IFS directory includes W (write), you are exposed to malware attacks. Use this to review and overcome this topic for the all important ROOT directory.
Root directory write exposure
NetServer Shares and IFS path availability.sql
I was asked to show how SQL could be used to identify when IBM i NetServer is sharing IFS paths, but some of those paths are unavailable.
IBM i NetServer shares
IFS_search_replace_and_create.sql
I was asked how ifs_read and ifs_write could be combined to build a new IFS stream file, where certain character strings are replaced.
Editing a stream file
Extracting the IFS filename from an absolute path name.sql
The request was, if you have an absolute path, how can SQL extract the filename from the path? One approach is found below.
Extract Filename from path
Searching the IFS for objects with "log4j" in the name.sql
The request from a client was to provide an SQL approach to search all of the IFS, finding any object that has "log4j" in its name, and producing an SQL table with the search results.
Find objects using search phrase

Manage your IFS with IBM i Services and ACS
With IBM i 7.3 TR8 and IBM i 7.4 TR2 there are many new IBM i Services that can really help make the management and understanding of your IFS easier. In this session we will look at some practical examples on how to better manage your Integrated File System (IFS) along with some new features to improve your experience with IBM i Access Client Solutions (ACS).

How to Read from an IFS Object
The latest TR has delivered an intriguing new IBM i Service. Being able to read the contents of an object from IFS.  Well, technically, its not 2 service, but 3, Text, Binary, and UTF8, so basically, you have pretty much every option covered. In this session we are not only going to show you HOW to read the contents, but we will also give you some hands-on look at why this is a very interesting new service.

Write to a File in the IFS
In the last session we showed you how to read the contents of a file in the Integrated File System. So, naturally, it makes sense in this session to show how to write content to an object in the IFS. This video is a 3 part story: 1. Something simple, write all the names of every library to a file.  2. Generate some JSON and write that in UNICODE to a file. 3. Write your favorite SQL into a file that can then be run in an automated manner.

Convert Spool files to PDF easy with SQL
There are many ways to convert spool files to PDFs.  Many are interactive though, which of course makes doing some in a scheduled or programmatic manner difficult!   There is NOW a easy solution to the issue, the Generate PDF helper function delivered in SYSTOOLS.  This means that now with a simple SQL statement you can find and convert spool files to PDF simple as pie.  In this session Scott and Tim show you this new tool with a live demo.
