After installation tweaking of , configuration files is required in order must be tweaked to utilize the installed RAM to the fullest extent. The main consumers of RAM are the operating system, the PostgreSQL database, and Tomcat. General The general rule for distributing allocating memory is to split it in ratio a 2:1 ratio between PostgreSQL and Tomcat, with 1 GB or more reserved for the operating system. For For instance:
Installed RAM | PostgreSQL | Tomcat | OS | Elasticsearch |
|---|---|---|---|---|
| 6 4 GB | 2 2 GB | 1 GB | 1 GB | 2 GB |
| 16 GB | 10 5 GB | 5 GB | 1 GB | 5 GB |
Tweaking PostgreSQL
Tweaking PostgreSQL for best performance is a topic on which many books were written, but the following are some common sense suggestions. For the curious ones, recommended reads (among countless others) are PostgreSQL Optimization Guide, and PostgreSQL Tuning Guide, this article and this book.
In order to apply the following tweaks, edit the file postgresql.conf, this file is usually located in the PostgreSQL data folder. You will need to to restart the PostgreSQL service after done editing. Almost all of the following parameters are commented with a carron character (#). Be aware that if you comment out the changed parameter that has been changed, PostgreSQL will , PostgreSQL will revert to the default value.

For the NetVizura 5.x, having MS Edge, Firefox or Chrome browser is mandatory requirement. |
| Tip |
|---|
Note that NetVizura demands postgresql installer which includes Microsoft Visual C++ pre-installation. Make sure that the postgresql installer you have downloaded installs Microsoft Visual C++ before postgres installation starts. Otherwise, you will need to install it manually. |
Tomcat Memory Allocation
During installation NetVizura automatically allocates memory for Tomcat process. The amount allocated to Tomcat process is calculated according to the formula:
(RAMtotal - 1GB) / 3 but no less than 1GB.
For instance:
Total RAM | Tomcat |
|---|---|
| 3 GB | 1 GB |
| 4 GB | 1 GB |
| 16 GB | 5 GB |
However, if you need to tweak Tomcat RAM allocation differently (the example for 2048MB):
- Double click on Apache Tomcat Properties in system tray
- In Java tab under Java options modify the
-Xmxparameter to allocate additional memory to Tomcat. Additionally, set parameter-Xmsto the same amount. Also set Initial memory pool and Maximum memory pool to the same amount. This should look like on picture below.
- Back to the General tab, click Stop and Start to restart Tomcat.
