I could tell you but I would have to kill you. ;) Actually, I need to be able to determine what the original job name is. Is the rule correct that every case - with no exceptions - of a forked/spawned address space has a single digit from 1 to 9 appended to the job name? If so, what happens after 9 such spawns? In addition, in my case, I have a spawned Java job. I'm finding that the JBNI and JBNS fields of both the ASCB and the ASSB point to the following names: JBNI..... TESTJOB1 JBNS..... BPXAS Now my question is can I rely and JBNS=BPXAS to determine the parent address space's name is equal to the child address space's name minus the child's last job name character? For those not familiar with BPXAS, here's a little copy and past from what I found: Beginning with OS/390 Version 2 Release 4, OS/390 UNIX System Services changed from usingAPPC initiators to Workload Manager (WLM) controlled initiators. The initiator address space name isBPXAS instead of ASCHINT. BPXAS is a special initiator with special interfaces to WLM and UNIXSystem Services.Fork and spawn use a WLM service to get an address space to process a request. The WLM servicechecks its queue to see if there is an idle address space from a free pool of BPXAS address spacesthat are waiting for work. If there are no idle BPXAS address spaces, WLM determines whether a newone can be created based on system load. If the free pool is empty, an ASCRE is done using thename BPXAS as the procedure to start a new one. When a BPXAS address space is finished, theaddress space goes back into the free pool. After 30 minutes of being idle, the address space isterminated.The spawn service is another way to create a new process. It looks like fork(), except that the newprocess is not a copy of the parent process. The child process inherits file and socket descriptors, aswith the fork(). With a spawn, the child process can be created in the parent address space.
