If you install ILM products on a 64-bit machine, you can allocate additional memory for the ILM Java Virtual Machine (JVM). To allocate additional memory, update the maximum heap size in the startApplimation batch file or script.
The default heap sizes for the ILM JVM are as follows:
Minimum heap size (-Xms) = 512 MB
Maximum heap size (-Xmx) = 1 GB
The default heap sizes are adequate for most installations on 32-bit machines. If you install ILM products on a 64-bit machine and notice performance issues, you might want to increase the maximum heap size for the ILM JVM. Set the maximum heap size to a value of 3 GB or less.
To configure the memory settings, update the following command in the startApplimation batch file or script:
