Databases in VMware vCenter 6.0

I upgraded to vPostgres database in vCenter 6.0 from MS SQL Express of vCenter 5.5. (Have 6 hosts, and about 100 VMs.) vCenter is working fine and I even backed up vPostgres database.
Two questions:
1. Why is MS SQL Express database still active? Its database files have current time and date. How do I get rid of it?
2. For Update Manager, vPostgres is no help. Do I need to install a full SQL database?

1. What is using it? Stop the SQL Service....could just be chatter...SQL DB are live all the time, whilst the service is running. Uninstall SQL Express.

2. SQL Express will do....which comes with Update do not need SQL FULL edition.

HOW TO: Update (Patch) VMware ESXi 6.0.0 GA to ESXi 6.0.0b with VMware Update Manager (VUM)

eventually, all will be on  vPostgres database!

2. Yes VUM has built-in SQL express but right under the checkbox it says -- for up to 5 hosts and 50 VMs.

I don't see how that is good enough for me.

Your environment is still considered small.

You can always monitor the SQL Express database does not grow beyond 10GB, it certainly would if this was vCenter Server 6.0, which is the reason for dropping SQL Express, because Essentials with three hosts and VMs, were Tasks and Events tables would grow very large due to noise.

(and if you look at the documentation it's still in Beta! with Draft comments!)

If it does, then upgrade to SQL Full version.

Database size depends on a few factors

how much scanning you do of hosts for patches, upgrades, VMs for VMware Tools Upgrades and virtual hardware upgrades.

if you do, 1 scan a month for tools, and hardware version, 2 scans a month for patches, 1 scan a month for upgrades, your SQL size will be small.

You are quite likely correct that 6 hosts and 100 VMs can be handled by SQL Express for VUM. But I may install full SQL version because that leave rooms for expansion. Unlike for vCenter itself where SQL database has to be customized with all kind of tables, here default SQL install should be good enough for VUM. Right? Thanks.

Yes, if you have the license, and it's not going to cost you.

Database usage is very light....

check Chapter 3 for details on SQL , default SQL install is okay.

remember the DSN is 32-bit, because Update Manager is only a 32bit app!

Thanks. (Yes I know the drill about 32 bit DSN since I added VUM instance to another VMware infrastructure which was using full SQL.)
