Do you know how to solve the issue of insufficient cache memory

[jeferson lemos]

Hi,

during the install of OrientDB, i had an error saying that I have no sufficient memory to run the application ( according to its current configuration ) and asking me to change the maximum cache usage memory limit for the application by using the command -Xmx on java:

2015-11-19 13:28:38:658 WARNI Not enough physical memory available for DISKCACHE: 2.006MB (heap=455MB). Set lower Maximum Heap (-Xmx setting on JVM) and restart OrientDB. Now running with DISKCACHE=256MB [orientechnologies]

The problem is that seems it is necessary point the command to some class or jarfile, but they dont say what is, anyway I tried the jarfiles orientdb-core-2.1.5.jar and orientdb-core-2.1.5.jar.

So I got the following errors:

nenhum atributo de manifesto principal em /home/jeferson/orientdb-community-2.1.5/lib/orientdb-core-2.1.5.jar

Do you know how to solve it?

I believe you can change the disk cache and heap sizes in a couple of ways. The easiest is to set them as properties in the "orientdb-server-config.xml" file.
