Out of Memory Error when running the SmartStor Tool.

Products

• CA Application Performance Management Agent (APM / Wily / Introscope)
• INTROSCOPE

Issue/Introduction

We are receiving the below error or similar when running Smartstor Tool:

java.lang.OutOfMemoryError: Java heap space 
at java.lang.String.<init>(Unknown Source) 
at java.io.DataInputStream.readUTF(Unknown Source) 

Environment

APM 10.8.*

Cause

 It is normal to see the Out of memory error when you run the stock script as it needs to load entire SmartStor data into memory first before executing any commands.

Typically the amount of heap needed to run SmartStorTools is directly proportional to size of SmartStor and you should set it to same heap settings as used by actual EM.

Resolution

 1.Open SmartStorTools.sh in a text editor

 2.Look for the below line:
JAVA_OPTS=-Xmx512m; export JAVA_OPTS 

 3.Change to:
JAVA_OPTS=-Xmx1500m; export JAVA_OPTS

4.Save the changes and rerun the script

If the OOM error still happens,  just repeat above steps until suitable heap size is found
