Some of you may recall I wrote a blog some time ago on SAS Visual Analytics auto load libraries. In that blog, I talked about using the autoload library that is created “out of the box” by SAS, here I am going to show you how to create additional autoload libraries if you want to separate your data for security or other reasons.
I have used Linux for this example, but it’s easy enough to change to Windows if that is your operating system.
Note: The order in which you do these things is not too important but feel free to follow along.
Operating system level changes
You will need to create a new set of physical folders. The first is where you will place your SAS tables to be loaded into memory, the next four sub-folders allow you to manage your tables.
Next we will create the scripts used to load the tables into memory
- Copy folder /SASConfig/Lev1/Applications/SASVisualAnalytics/VisualAnalyticsAdministrator/VALIBLA and all of it’s contents to a new folder in the same location called DV
- Within the new folder you created edit and change the follow files as below
- Autoload.sas – Change the LASR library name to “Data Vault”
- runsas.sh – Change the libref to “DV”
- schedule.sh – Change the libref to “DV”
- unschedule.sh – Change the libref to “DV”
Action in SAS Metadata
You need to create a new SAS LASR library. Use the wizard and enter the values below when requested.
- Type of Library – SAS LASR Analytic Server Library
- Location – Data Vault\LASR Data
- Name – Data Vault
- Server Tag – DV (this must be unique, so I use the libref to keep it simple)
- Libref – DV
Now update the properties for the LASR library, under the Extended Attributes tab change the following
- change VA.Default.MetadataFolder to Data Vault\LASR Data
- change VA.AutoLoad.AutoStart to Yes
- change VA.AutoLoad.Enabled to Yes
- change VA.AutoLoad.Location to /SASData/Autoloads/DataVault
- change VA.AutoLoad.Sync.Enabled to Yes
- change VA.AutoLoad.Sync.Import to Yes
- change VA.AutoLoad.Sync.Load to Yes
- change VA.AutoLoad.Sync.Refresh to Yes
- change VA.AutoLoad.Sync.Append to Yes
- change VA.AutoLoad.Sync.Unload to Yes
- leave VA.AutoLoad.Debug.Enabled as No
- change VA.ReloadOnStart.Enable to Yes
- change VA.ReloadOnStart.TableDefault to Yes
- leave VA.ReloadOnStart.Method as All
Now lets turn it on
The last step is enablement. There is nothing special about this, all we need is a batch job to run every 15 minutes to load any new or updated tables into memory. Executing the schedule.sh job you edited earlier will add a batch job to the cron scheduler running every 15 minutes.
I have used a library name of Data Vault and a libref of DV for this example.
Hopefully, this will make your life easier as it has made mine.
