Environmental parameters

Default values are assigned to the environmental parameters during installation and customization of BMC AMI Ops Monitor for Java Environments. For more information about changing the default values, see Reviewing-and-defining-BMC-AMI-OpsMJE-PAS-parameters. You can also view the sample MJEENV00 member.

The following table describes the environmental parameters:

Parameter	Default value	Description
_BPX_JOBNAME=jobName	No default	Specifies the MJEJVM job name Important The jobName cannot include the following special characters: ! ” # % ’ : ; < = > ? [ \ ] ^ ` { \| } $ @
_BPX_SHAREAS=[YES\|NO]	NO	Specifies whether the spawned child process should run in a separate address space from the shell address space Valid values are as follows: YES—Creates the child process on a subtask in the parent's address space If the request cannot be honored, the child process is created in another address space. (Default) NO—Creates the child process in a new address space
_BPXK_MDUMP=jvmDumpDirectory	No default	Specifies the directory to which Java dumps are written Important The directory must already exist.
COREMJETHREADS=minNumThreads	No default	Specifies the minimum number of threads in the thread pool You can calculate this value as follows: <numberOfMonitoredJMX> * 3 Important This value must be greater than zero but less than the MAXMJETHREADS value.
HCTMPDIR=directory	/tmp	(Optional) Specifies the directory for routing IBM Health Center temporary generated files and Strobe measurements JSON files. Important The directory must already exist. If you do not specify HCTMPDIR, the files are routed to the /tmp directory.
HOLDQSIZE=numThreads	No default	Specifies the maximum number of threads that can be held in the queue which are waiting for execution while all threads are busy We recommend using the MAXMJETHREADS value for the HOLDZSIZE value.
JAVA_HOME=location	No default	Specifies the location of Java 8.0 64-bit
KEEPALIVESEC=maxTime	No default	Specifies the maximum time in seconds to retain inactive threads in the thread pool The recommended time is 90 seconds.
MAXMJETHREADS=maxNumThreads	No default	Specifies the maximum number of threads allowed in the thread pool Important This value must be greater than the COREMJETHREADS value You can calculate this value as follows: <valueOfCOREMJETHREADS> * 2
MJEPATH=directory	No default	Specify the mount point for mounting BMC AMI OpsMJE ZFS files Important The directory path or linked directory path cannot include the following special characters: ! ” # % ’ : ; < = > ? [ \ ] ^ ` { \| } $ @
MONINT=monitoringInterval	No default	Specifies the self-monitoring interval time in seconds The recommended time is 60 seconds.
OUTPATH=directoryPath	No default	Specifies the directory to which to write BMC AMI OpsMJE messages Important The directory must already exist.
TCPMJEPORT=portNumber	20334	Specifies the number of the port through which the product communicates with the MJEJVM and Strobe systems Important If the default value is omitted and you need to change the value, you must explicitly enter the value TCPMJEPORT=portNumber in the MJEENVxx BBPARM member by using the ISPF editor. Tip You can get this port number from the TCP/IP port assigners.
WLP_DIR=directory	No default	Specifies the IBM WebSphere Application Server Liberty profile bin (wlp) directoryThe product uses this directory to locate the client's subdirectory. The subdirectory contains the restConnector.jar file, which is used to gather JMX data from Liberty servers.
XMS=initialHeapSize	4096	Specifies the MJEJVM initial heap size in MB Important If the default value is omitted and you need to change the value, you must explicitly enter the value XMS=initialHeapSize in the MJEENVxx BBPARM member by using the ISPF editor.
XMX=maximumHeapSize	4096	Specifies the maximum MJEJVM heap size in MB Important If the default value is omitted and you need to change the value, you must explicitly enter the value XMX=maximumHeapSize in the MJEENVxx BBPARM member by using the ISPF editor.
HCCHILDIP=x.x.x.x	localhost	(Optional) Specifies the primary TCP/IP address (ipv4) associated with MJESTACK MJEJVM child connects to the Health Center agent using the HCCHILDIP IP address to collect Health Center data. x.x.x.x must have a decimal value between 0 and 255. For example: 192.240.0.36 Tip Consider adjusting your HCCHILDIP parameter accordingly if you change the TCP/IP stack name for the MJESTACK parameter.
