Using QIBM_JAVA_PASE_CHILD

The QIBM_JAVA_PASE_CHILD_STARTUP environment variable indicates the i5/OS™ PASE startup program for any secondary JVMs.

Use QIBM_JAVA_PASE_CHILD_STARTUP when all of the following conditions are true:

The Java™ application that you want to run creates Java virtual machines (JVMs) through Java calls to Runtime.exec()
Both the primary and secondary JVMs use i5/OS PASE native methods
The i5/OS PASE environment of the secondary JVMs must be different than the i5/OS PASE environment of the primary JVM

When all of the previously listed conditions are true, perform the following actions:

Set the QIBM_JAVA_PASE_CHILD_STARTUP environment variable to the i5/OS PASE startup program of the secondary JVMs.
When starting the primary JVM from an iSeries™ command prompt or Qshell command prompt, set the QIBM_JAVA_PASE_STARTUP environment variable to the i5/OS PASE startup program of the primary JVM.
Note: When starting the primary JVM from an i5/OS PASE terminal session, do not set QIBM_JAVA_PASE_STARTUP.

The process of the secondary JVM inherits the QIBM_JAVA_PASE_CHILD_STARTUP environment variable. In addition, i5/OS sets the QIBM_JAVA_PASE_STARTUP environment variable of the secondary JVM process to the value of the QIBM_JAVA_PASE_CHILD_STARTUP environment variable from the parent process.

The following table identifies the resulting i5/OS PASE environments (if any) for the various combinations of command environments and definitions of QIBM_JAVA_PASE_STARTUP and QIBM_JAVA_PASE_CHILD_STARTUP:

Table 1. Resulting PASE environments for QIBM_JAVA_PASE_STARTUP and QIBM_JAVA_PASE_CHILD_STARTUP
Starting environment			Resulting behavior
Command environment	QIBM_JAVA _PASE_STARTUP	Primary JVM i5/OS PASE Startup	Primary JVM i5/OS PASE Startup	Secondary JVM i5/OS PASE Startup

CL or QSH	Defined startX	Not defined	Use startX	Use startX
CL or QSH	Not defined	Defined startY	No i5/OS PASE environment	Use startY
CL or QSH	Not defined	Not defined	No i5/OS PASE environment	No i5/OS PASE environment
i5/OS PASE terminal session	Defined startX	Defined startY	Not allowed*	Not allowed*
i5/OS PASE terminal session	Defined startX	Not defined	Not allowed*	Not allowed*
i5/OS PASE terminal session	Not defined	Defined startY	Use i5/OS PASE terminal session environment	Use startY
i5/OS PASE terminal session	Not defined	Not defined	Use i5/OS PASE terminal session environment	No i5/OS PASE environment

* The rows marked "Not allowed" indicate situations where the QIBM_JAVA_PASE_STARTUP environment variable could conflict with the i5/OS PASE terminal session. Because of the potential conflict, using QIBM_JAVA_PASE_STARTUP is not allowed from an i5/OS PASE terminal session.
