Update SharePoint 2013 to August 2013 CU

If you are planning to upgrade your SharePoint 2013 Farm to August 2013 Cumulative Update, consider following consideration:

1 - Go to this link to Request download for the CU
1.a - For SharePoint foundation the link is this one kb2817517.
1.b - For SharePoint Server the link is this one kb2817616.

2 - You already heve installed March 2013 SharePoint 2013 Public Update (PU)

3 - The update take a lot of time to complete. If you want to minimize this, read this interesting article "Why SharePoint 2013 Cumulative Update takes 5 hours to install?".

4 - After the update, you obviously need to run SharePoint Configuration Wizard. Using standard psconfigwiz.exe the update is performed in timer job. If you are experiencing issues using this approach, you can run psconfig.exe from command line with this parameters:

PSConfig.exe -cmd upgrade -inplace b2b -wait -force -cmd applicationcontent -install -cmd installfeatures

Note the -wait parameter that tell psconfig.exe to run the upgrade process not in the timerjob process, but in current process session.

The -force parameter tell psconfig.exe to ignore previous Upgrade Timer Job defined in configuration database.

In my case, running the upgrade in timerjob cause the upgrade process to be stucked on 10%.
