Name Indexing (DBCFG.INI)
Name indexing should be enabled on all databases especially those with over 1000 endpoints or users. It will
be noticeably faster and improve performance.
To do this, create a basic text file called DBCFG.INI; file and copy it to the SBDATA folder (assuming default
location for Object Directory) and edit as below:
Warnings
•
Do not use Single File mode as shown in the options below. It can be used for small databases but not
recommended as it can be much slower.
•
The Find function does not use the name cache and therefore searches the complete database
sequentially.
DBCFG.INI
Sections are added defined by [] with the options in each section added as below.
[NameIndex]
Enabled=Yes
This must be set to "Yes" for the name index/caching to be used by programs running for this directory.
LockTimeout=3000
This option controls how long the process will retry access to the index file if it is locked. You can decrease this
value if the administrator experiences long waiting times during installation, for example – 1000, however,
only in databases smaller than 5000 systems, otherwise you find the number by multiplying the number of
users or systems in the database by 0.6.
Example: If the number of users in the database is 10,000, the Locktimeout should be 6000.
The default value is 3000.
The value is in 100ths of a second.
In case of multiple servers, the timeout can exceed due to many simultaneous connections. In that case the
value needs to be increased to 30000.
LockSleep=10
This option controls how long the process will sleep (wait) before re‐trying opening a locked file. The value is in
1000ths of a second. In case of multiple servers, the locksleep might need to be increased due to many lock
timeouts. In that case the value needs to be increased to 100 or even 1000.
HashCount=16
This option controls how many "buckets" the hash of the name is split into. It should be between 1 and 256
(default 16). Generally, a good value can be calculated by taking the square root of the number of users.
However, for optimal performance this value should be tuned by testing.
MinEntrySize=16
This is the minimum space to allocate per object name in the index file. The default of 16 is a good value if the
names do not exceed 16 characters. You do not need to specify the value if the names do not exceed 16
characters.
