Server Memory Size


This article is about changing memory size used by the Spotfire server java instance.
In most cases you will not need to modify it, however if you see issues around java process running out of memory, this may help
Quoted from Spotfire server installation manual



Modify the Virtual Memory. To set up the start script when not running as a Windows service:
==========================================================
1). Open the file <installation dir>/tomcat/bin/setenv.bat/.sh in a text editor, such as Notepad.

2). Locate the line that sets the variable JAVA_OPTS:
    set JAVA_OPTS=‐server ‐XX:+DisableExplicitGC ‐XX:MaxPermSize=256M ‐Xms512M ‐Xmx1536M
    or
    JAVA_OPTS="‐server ‐XX:+DisableExplicitGC ‐XX:MaxPermSize=256M ‐Xms512M ‐Xmx1536M".

3). Alter the -xms and the -Xmx values ‐Xms512M ‐Xmx1536M to the amount of memory you wish to allocate.

4). Save the file.

5). Restart the server.

To set up the start script when running as a Windows service:
=================================================
1). Stop the TIBCO Spotfire Server service.

2). Go to the <installation dir>/tomcat/bin directory.

3). Run the command: service.bat remove.

4). Edit the <installation dir>/tomcat/bin/service.bat file.

5). Look for the entries: ‐‐JvmMs 512 ‐‐JvmMx 1536 .

6). Alter 512 and/or 1536 to suitable memory values (in megabytes).

7). Run the command: service.bat install.

8) Start the TIBCO Spotfire Server service.

NOTE - For 32-bit Windows operating systems, spotfire  generally recommend never going above 1300M for the heap size.  If you set the value too high, the server will fail to start. Note that this is a Java/OS limitation - it has nothing to do with Spotfire.

For 64-bit, the highest tested size is 2048M.

Using Accordions in Spotfire Text Areas

Spotfire 6.0 provides great tools for quickly building your dashboard, but here we will learn to spice up things with the help of new 6.0 text area. If you are not aware the new 6.0 Text area supports HTML, Javascript and CSS. This opens up possibilities for doing a lot more with the text area. Some of the basic stuff can be seen here http://spotfire.tibco.com/qrt/UBSAN/presentation.html?pcode=100044   One of the cool things you can do is build an accordion panel in the text area for better utilization of the valuable screen real estate and helping the overall experience.(Watch the 0:15 second video below to see how accordion works - Sorry for the jitter in the video. The screen recorder does not record fast enough) Here is the html behind the text area : Please note that Spotfire controls are automatically created when you add text area controls, like filters, drop down lists etc. <DIV id="myaccordion"> <H3>Analysis Details</...

Something like this I basically used a scatterplot for this.  You can check out the original DXP here  http://bit.ly/spotcalendar Some key settings to make it a calendar.

Spotfire Auto Save for recovery

This is an extension I build to auto save local copies of currently open DXP every 15 minutes.. I have tested briefly and it seems to be doing its job, please please please try and test it if you can access a server and deploy.. Key Notes - This add-on will Auto Save Files while only in Spotfire Analyst Client. The save time is hard coded for every 15 minutes. Files are saved only if they are changed or user has done some actions like marking, filtering etc. The Files are saved in temporary location of the system, generally which will be like C:\Users\<username>\AppData\Local\Temp\Spotfire AutoSave If a Library file is opened it will be saved on your local machine under the temp path C:\Users\<username>\AppData\Local\Temp\Spotfire AutoSave\Library Content\ Library path will be replicated in this autosave location. e.g. C:\Users\<username> \Local\Temp\Spotfire AutoSave\LibraryContent\mylibraryfolder\mylibraryfilename_mmddyyyy_HH...
