Configuring the Java virtual machine heap size

During a model build process, the Data Training subtask initiated by the BMC AMI Ops Insight Tomcat server utilizes a JVM heap size of 40 GB. If the allocation fails, you might get the following error: 

To override the default memory

Perform the following steps to override the default 40 GB memory required by the Data Training subtask:

1. Edit the Tomcat AMITCJCL in your system PROCLIB and add export MODELGEN_MEMORY in environment variables as follows:
   (BMC.AMIOPS.SPE2304)

   ---------------------------------------------------------------------
   Set AMI modelgen env variables                                       
   ----------------------------------------------------------------------
   export MODELGEN_PATH=$AMI_INSTALL_PATH/datatrain                                 
   
   export MODELGEN_JAVA=$AMI_INSTALL_PATH/java/J8.0_64                    
   
   export MODELGEN_MEMORY=10g                   <=== Ex. 40g, 1g, 1000m

2. Update AMITCJCL to force the Tomcat server to pick up AMITCEN6 from UBMCSAMP as follows:

   //STDENV DD *,SYMBOLS=JCLONLY < STDENV shell script
   export AMI_INSTALL_PATH=&AMIINST/aoihome
   export AMI_DATA_PATH=&AMIINST/aoidata
   export AMI_HOME=&AMIINST/aoihome/oi_home
   //              DD DISP=SHR,
   //                    DSN=&CNFGLIB1(&TCENV) < STDENV shell script
3. Restart the Tomcat server.
