Recently, when using jdeveloper 10.1.3.3, it was found that the speed was extremely slow. After Google found the following solution: Add the following two lines at the end of the jdev. conf file to significantly improve the speed.
Addvmoption-dsun. java2d. noddraw = true
Addvmoption-dsun. java2d. ddoffscreen = false
The jdev. conf file is located under the jdevbin \ jdev \ bin directory.
[Oracle BPM/SOA Basics] BPM/SOA server JVM parameter settings
Due to Oracle BPM/SOA's thirst for memory requirements, JVM parameter setting affects server execution performance to a considerable extent.
For 64-bit JVM, we recommend that you set the heap size to at least 2048 MB and pergen space to MB if possible ~ 768 m.
To change the JVM parameter of SOA startup, you can modify the <domain> \ bin \ setsoadomainenv. CMD file.
64-bit JVM needs to find port_mem_args, 32-bit, then modify the default_mem_args parameter. below is my 8g RAM Windows 7 BPM environment settings, for your reference:
Set java_options = % java_options %
Set default_mem_args =-xms512m-xmx1024m
Set port_mem_args =-xms3200m-xmx3200m
If "% java_vendor %" = "oracle" Goto oraclejvm
Set default_mem_args = % default_mem_args %-XX: permsize = 128 M-XX: maxpermsize = 512 m
Set port_mem_args = % port_mem_args %-XX: permsize = 512 M-XX: maxpermsize = 768 m
In addition, if you encounter a jdeveloper slow or complain memory issue during development, you can also modify and edit <middleware_home> \ jdeveloper \ ide \ bin \ IDE. CONF file to change the JVM parameters used by jdeveloper:
Addvmoption-xmx1280m
Addvmoption-
