synchrony.memory.max

[Вадим Дроздов]

I read manual before asking a question. Catalina_opt passes parameters to JVM. Java doesn't understand this option. Confluence not working, I've tried different options for setting the option, the answer is always "Unrecognized VM option".

Hi Vadim Drosdov,

Is your Confluence application server based on Linux or Windows?
If Windows is based, is the service or .bat file started?
If the service is, see Setting Properties for Windows Services via Command Line. (Point 4)
Set the entry:  -Dsynchrony.memory.max=2g

Start on Windows with bat file
The following entry in the setenv.bat

set CATALINA_OPTS=-Dsynchrony.memory.max=2g %CATALINA_OPTS%

[Reinhard Piltz]

If Linux is based:
The following entry in the setenv.sh

CATALINA_OPTS="-Dsynchrony.memory.max=2g ${CATALINA_OPTS}"
