Title

How to Disable the file cache
Description

In some situations, problems may arise when writing the information from the One Identity Manager (1IM) database into a Frontend (i.e., Manager, Designer) local cache takes an excessive amount of time.

In this case, disabling the writing into the file cache can solve the issue.
Cause

Over time, 1IM collects a lot information which is frequently used in the data model (table/column definitions, permissions, translations, etc.)

All this data is gathered when it is initially needed, loaded into the memory cache and stored synchronously in the file cache. If storing the data into file cache is slow, the whole application needs to wait.

This behaviour has been changed in future versions of 1IM, but in 6.1.2 the only option is to disable the file cache.

The in-memory cache invalidates data which has been not used in the last 15 minutes, which means by disabling the file cache, 1IM is forced to load this part of the information from the database. This is also done with active file cache when information changes in the database (e.g. by adding new column, new permission or translations).

With this change, the traffic between the 1IM application and the Database is expected to increase, however, as data can be loaded faster from the Database, the overall impact should be low.
Resolution

To disable the file cache, setup the "ConnectionBehaviour" section in these files:

For web portal: web.config

For frontends: <Frontend>.exe.config

In the .config file is a section:

<connectionbehaviour>

In the next line, as part of this section, add the following:

<add key="CacheType" value="None" />

Example:

<connectionbehaviour>
<add key="CacheType" value="None" />
<add key="sqllogdir" value=""/>
</connectionbehaviour>

Instead of the above, if preferred, the following modification can be made in the registry:

--- Windows Registry file ----
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Quest Software\Identity Manager\ObjectBrowser\ConnectionBehaviour]
"CacheType"="None"

[HKEY_CURRENT_USER\Software\Quest Software\Identity Manager\Manager\ConnectionBehaviour]
"CacheType"="None"

[HKEY_CURRENT_USER\Software\Quest Software\Identity Manager\Transporter\ConnectionBehaviour]
"CacheType"="None"

[HKEY_CURRENT_USER\Software\Quest Software\Identity Manager\DataImporter\ConnectionBehaviour]
"CacheType"="None"

--- Windows Registry file ----
