Add Memory to Directories Management
You may need to allocate additional memory to Directories Management if you have Active Directory
connections that contain a large number of users or groups.
By default, 4 GB of memory is allocated to the Directories Management service. This is sucient for many
small to medium sized deployments. If you have an Active Directory connection that uses a large number of
users or groups, you may need to increase this memory allocation. Increased memory allocation is
appropriate for systems with more than 100,000 users , each in 30 groups and 750 groups overall. For these
system, VMware recommends increasing the Directories Management memory allocation to 6 GB.
Directories Management memory is calculated based on the total memory allocated to the vRealize
Automation appliance The following table shows memory allocations for relevant components.

18 GB 3.3 GB 4 GB
24 GB 4.9 GB 6 GB
30 GB 7.4 GB 9.1 GB
N These allocations assume that all default services are enabled and running on the virtual appliance.
They may change if some services are stopped.
Prerequisites
n
An appropriate Active Directory connection is congured and functioning on your
vRealize Automation deployment.
Procedure
1 Stop each machine on which a vRealize Automation appliance is running.
2 Increase the virtual appliance memory allocation on each machine.
If you are using the default memory allocation of 18 GB, VMware recommends increasing the memory
allocation to 24 GB.
3 Restart the vRealize Automation appliance machines.
Create a Domain Host Lookup File to Override DNS Service Location (SRV)
Lookup
When you enable Integrated Windows Authentication, the Directory conguration is changed to enable the
DNS Service Location eld. The connector service location lookup is not site aware. If you want to override
the random DC selection, you can create a le called domain_krb.properties and add the domain to host
values that take precedence over SRV lookup.
Procedure
1 From the appliance-va command line, log in as the user with root privileges.
2 Change directories to /usr/local/horizon/conf and create a le called domain_krb.properties.
3 Edit the domain_krb.properties le to add the list of the domain to host values. Add the information as
<AD Domain>=<host:port>, <host2:port2>, <host2:port2>.
For example, enter the list as example.com=examplehost.com:636, examplehost2.example.com:389
4 Change the owner of the domain_krb.properties le to horizon and group to www. Enter
chown horizon:www /usr/local/horizon/conf/domain_krb.properties.
