Resource usage
There are commands which can help you determine your system's memory usage.
Mem Show
Use the Mem Show command to determine the current memory usage for HCL Traveler.
The HCL Traveler server is implemented as a Java™
Domino® server task, so it uses memory from both the Java™ memory heap and native Domino® memory.
The
following example shows the output of the Tell Traveler mem command.
The command shows a snapshot of the memory and processor usages over
the last 24 hours in 15 minute intervals at the beginning of the display.
Each of the intervals show an estimate of the processor usage over
the 15 minute interval as well as a current snapshot of both the Java™ Memory and C Native memory.
This allows the administrator to see trends of the processor and memory
usage over a 24 hour period. Detailed memory usage statistics follow
the snapshot interval information.
tell traveler mem to report memory utilization by the primary
HCL Traveler process.

C 2748 MB In this example, the Java™ Virtual Machine (JVM) for HCL Traveler has allocated only 96 MB of heap memory and 57 MB of that heap is still free. So this server is well below the maximum Java™ heap limit of 512 MB. The C Mem Virtual Usage section reports the overall process memory, which includes any memory allocated by the Java™ heap and all other Domino® shared memory. In this example 8388608 MB can be used for this process, and there are 8387017 MB free for further allocation. When HCL Traveler is running on a 32-bit Domino® server (Either Windows™ or Linux™), the limit for the application C memory space is 2 GB by default. If this was a 64-bit Windows™ server, then the maximum available memory would be 4 GB if the Domino® server code was 32-bit and higher than 4 GB if the Domino® server code was 64-bit.
