TechTip: Managing the IFS Using iSeries Navigator

When I speak with users about iSeries Navigator's IFS function, they are often surprised to find out about one easy-to-use function that they didn't know even existed. In this tip, I'll talk about sharing a folder and ways you can take advantage of it.

Share a Folder and Its Data

The concept is simple enough. You have a folder in the IFS on your iSeries and you want to access that folder from your desktop PC. The steps to share a folder are simple enough as well.

First, open iSeries Navigator. Sign onto your favorite iSeries system and navigate to the File Systems folder. Open the Integrated File System folder and navigate to the folder you want to access from your PC. Right-click on that folder and select Sharing -> New Share. The dialog that comes up will default settings like the name of the share and the default access rights (Figure 1). Select the defaults and click OK, and you're all set.

Now, simply open your PC search function to find the computer (your iSeries name), and your shared folder will appear under the computer name. Another option is to simply type the directory path: Systemnamefilename.extension.

For example, if you share a folder off the root directory on System1, it would be System1 ootmyfolder, but if you share a library off of QSYS, then the path would be System1qsys.libmylib.lib. See the extensions? I know it's confusing, but that's the life of mixing QSYS and IFS objects.

The name listed above is the name of the file share, which can be different from the folder name. It's important to know that a file share is an object all its own (we call it a "file system shared object"). It can be added, removed, even have permissions assigned to it. In fact, a single folder can have multiple file shares created. They all point to the same folder, but they have different names and potentially different access settings. The important difference is that you can set up different permissions on each file share to control who can have access to the folder. For example, I could set up GregFolder and FredFolder as file shares. GregFolder could provide read-only access, whereas FredFolder could provide read/write access. Further, each file share's permissions could be set up so that only user profiles Greg1, Greg2, and Greg3 can access file share GregFolder, whereas all user profiles in group THEFREDS (all profiles named with FRED) can use FredFolder.

How do you set unique permissions on a file share? It's not all that straightforward. You'd think all you would do is select the file share from the File Shares folder, but that would be too simple. Instead, you have to right-click on the File Shares folder, select the Open iSeries NetServer menu, and find your share name in the iSeries NetServer window (Figure 2). Right-click on the share name and select Permissions. From here, you can add users or user groups. You can also select an authorization list that will be used to secure the file share. This is recommended because authorization lists can then be managed by function or type of user, and once a user and object is added to an authorization list, you can clearly see who can use that object.

One other nice feature is that you can view which PCs are currently connected to a shared object. Simply click on the file share in the left tree, and the PCs currently connected will show up in the right (see Figure 3).

Besides the normal "network drive access" benefits that come with sharing a folder, you can use functions like InfoPrint Server, which allows you to create PDF files from printer output and put the created PDF into an IFS folder. This is great because you can set your boss up with the I: drive that points to the iSeries, and when a new report comes in, just click "Convert to PDF" and put it in the folder that's shared. Simple! Or you could share a folder for a tester, and when he encounters a problem, he can dump any job log data or command output to this shared folder so that the developer doesn't even have to sign onto the iSeries.
