7.8 Improving CDE Application Performance

Tip 

How do I improve the performance of CDE applications in the GNOME 2.0 Desktop? 

Action 

By default the following CDE programs are turned off when you log in to a GNOME Desktop session:

• dtdbcache

  dtdbcache sets up a cache to speed up CDE programs that use actions such as dtfile. If this cache is not set up, CDE applications that use actions run more slowly. To turn this feature back on, you can start this program manually or by launching the program from a startup script. Perform the following actions:

  1. Log in as root, then open the following file: /usr/dt/config/Xsession.Sun-gnome-2.0–fcs

  2. Delete the following line: export SDT_NO_DTDBCACHE="1"

• ttsession

  ttsession is the Tooltalk daemon. In CDE, this program is always launched when the user first logs in. In the GNOME 2.0 Desktop, this daemon is started automatically by the first program that makes use of Tooltalk. You can restore the CDE behavior by using a startup script. Perform the following actions:

  1. Log in as root, then open the following file: /usr/dt/config/Xsession.Sun-gnome-2.0-fcs

  2. Delete the following line: export SDT_NO_TOOLTALK="1"

• dtappgather

  dtappgather is a support program for the CDE Application Manager. Normally, you do not need to run this program in a GNOME Desktop session. However, if you want to run this program, then you can start dtappgather manually or by launching the program from a startup script. Perform the following actions:

  1. Log in as root, then open the following file: /usr/dt/config/Xsession.Sun-gnome-2.0-fcs

  2. Delete the following line: export SDT_NO_APPGATHER="1"
