Publicly Accessible minidisks
Hello List, I'm wrapping up the install of DFSMS/VM...yikes...not the most intuitive install I've ever done.

Re: Publicly Accessible minidisks
That would cause the disk to be LINKed, but it still needs to be ACCESSed as well. Chris, your best advice is to set up a minidisk that is for public stuff that you don't want to put on the MAINT 190 or 19E minidisk (the ONLY two system disks that are automatically accessed when CMS is IPL'ed). You will find that there are going to be things that you want all users to have access to, and you may want to override certain things on the 190/19E minidisks so access your local public disk at a filemode lower than S (say R or Q). I am assuming that you have standard PROFILE statements in your CP source directory (whether using an ESM like VM:Secure, DIRMAINT or nothing at all). For the purposes of this discussion, let's say you create a userid named PUBLIC and its 191 disk is what you want all users to access as R, linked as 319. You'll create a little exec named VMCONFIG to do your local customizations: 1. Add the following to your directory PROFILE(s): LINK PUBLIC 191 319 RR 2. Modify the SYSPROF EXEC on the MAINT 490/190 disk(s) to call a local user exit. HINT: Your code should execute right after the 'SET COMDIR RELOAD' statement. Remember that SYSPROF EXEC is in the INSTSEG so you'll need to resave this once your updates have been made, and of course since this is a CMS system minidisk makes your changes to MAINT 490, test them, then promote them to MAINT 190 using VMSES update procedures. 3. Create your VMCONFIG EXEC and put it on PUBLIC 191. It can be as simple as one statement which reads ACCESS 319 R, but of course since ALL users will now execute this you can be a lot more creative if you choose to. My VMCONFIG customizes virtual machines based on CP account numbers and ACIGROUPs. That's it! You now have a public disk that all users will have access to. It preceeds the CMS minidisks so you can override programs on the CMS minidisks if you need to (assuming they aren't NUCX or EXEC loaded, in which case you'll need to make sure the RIGHT programs get loaded accordingly). Put ANY stuff that you want all users to have access to on PUBLIC 191 and they'll automagically pick up access to it at filemode R. -Mike -Original Message- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Alan Altmark Sent: Tuesday, May 27, 2008 9:50 AM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Publicly Accessible minidisks On Tuesday, 05/27/2008 at 09:41 EDT, Hilliard, Chris [EMAIL PROTECTED] wrote: I?m wrapping up the install of DFSMS/VM?yikes?not the most intuitive install I? ve ever done.

Re: Publicly Accessible minidisks
To make that disk PUBLIC these days, I would give it a Read-Password of A LL (or set appropriate rules in your ESM product of choice) and put an entry for it in a USERPROD NAMES file on the Y-Disk. These steps should allow a ny user to issue the 'VMLINK DFSMS_nickname' command and get the minidisk linked and accessed. Inside the USERPROD NAMES entry you can specify the virtual address and access mode that you want to be used. If you then want ALL users to get the minidisk automatically (I don't kno w why, but you might) then you can put that VMLINK command into your SYSPRO F EXEC extension. /Tom Kern /301-903-2211 On Tue, 27 May 2008 09:40:48 -0400, Hilliard, Chris [EMAIL PROTECTED] wrote: I'm wrapping up the install of DFSMS/VM...yikes...not the most intuitive install I've ever done.

Ooops, correction - the ACCESS 319 R statement must (of course) be in SYSPROF prior to calling your local VMCONFIG EXEC to do other things.

Re: Hipersockets - xposted to VM-L IBM-Main
Maybe you are not even using port name on z/OS. I don't know much about z/OS, so I cannot help you find it, but even if you are not using port name in z/OS, you have to be sure that nothing else comes up before the z/OS guest, connects to the hipersocket and changes port name from nothing into something.(1) Did you check your z/VSE stack for a port name? (2) Did you have a chance to reset the hipersocket CHPID (vary off the CHPID from all LPARs *at the same time*, then vary it on to all)? I remember that on z800 hardware port names could differ in one character out of eight (but one only), and microcode check would pass. Eg, port names HSOA1 and HSOB1 were OK, but not HSOB2. Later on I found out that this is in fact how it worked. This applied both to hipersockets and OSA's. From z990 onwards, this slack was removed and from then on all port names must be identical or not used at all. So, if you don't really need port names (and z/VM allows you to not use them from release 4.4 onwards), this exercise of removing them is well worth your while. And if you do (1) and (2) above, you will at least be sure that port name is *not* your problem. Then, we'll dig deeper.

A mismatched port name on an OSA creates an initialization error. In any case, HiperSockets do not have port names. On z/OS they are addressed solely by chpid (DEVICE IUTIQDxx). My apologies for creating confusion; I was addressing only the incorrect assertions about port names rather than focusing on the problem at hand. It's been a while and I've forgotten the details, but HiperSocket communication requires: 1. Both LPARs reference the same HiperSocket chpid. Note that z/OS does not allow specification of a HiperSocket chpid that is being used for dynamic XCF. Verify: Get a packet trace to see that packets are being place on and received from the HiperSocket. 2. Both IP stacks have correct local routes. That is, the same subnet and subnet mask with no gateway specification. Verify: Look at the routing table. Make sure the gateway for the HiperSocket subnet is 0.0.0.0. And make sure you don't have overlapping routes. 3. Both stacks are using the same MTU and that MTU is consistent with the MFS value in the chpid definition. Verify: It shouldn't cause a problem with PING, but will result in lost packets for any frame that exceeds the MTU of the receiver. If you want to do all that, fine, but I'd suggest first bringing up both images as z/VM guests and connect them to a HiperSocket Guest LAN instead of real HiperSockets. Be sure to use the CHPID parameter on the NICDEF for a z/OS guest to ensure that the correct virtual chpid is chosen, matching your real HiperSocket chpid number. Compare the routing tables. They should be the same, virtual or real, as far as the HiperSocket interface is concerned. By the way, I'm not cross-posting to IBM-MAIN.

Does z/OS speak TCPNJE? I thought it had to be SNANJE (at least that was the deal back in 2002 when I last looked into this). Have the z/OS guys finally seen the light and provided a TCPNJE protocol? Yes, finally, z/OS 1.7 and later have TCPNJE (although you need some PTFs for it to work correctly on 1.7). Previous to 1.7, you'd need either RSCS (SNA or CTC) or the full NJE Bridge (via CTC).
Re: JAVA and Z/VM
Ed, The Java and NetRexx support discussed in the redbook, VM/ESA Network Computing with Java and NetRexx, was discontinued before z/VM 5.1.0 became generally available. The level of Java had become very outdated. If you want and need Java support, you should be looking at running it from a Linux guest. Thanks! Mike Donovan Edward M.

A Saleman indicated that Unfortunately, IBM doesn't support Java on VM yet, and our Oracle and SQL Server Interfaces are written in Java. I have found a redbook VM/ESA Network Computing with Java and NetRexx. Thanks for any info. Ed Martin 330-588-4723 ext 40441

Exactly what Oracle and SQL server did you develop your Java for? Are you talking about server side Java apps? Or are you talking about just needing compatibility in the server so that your client-side Java apps can talk to it (i.e. JDBC). If you're running these databases run on Linux, not CMS, the lack of Java support in CMS doesn't matter. Alan Altmark z/VM Development IBM Endicott
Re: Hipersockets
Alan, A mismatched port name on an OSA creates an initialization error. Correct, but with a caveat explained in the other thread (yes for z990 onwards, before z990 one character could mismatch. I know it sounds weird, but that's the way it worked) In any case, HiperSockets do not have port names. Ummm, no. They can be specified for HiperSocket connection in DEVICE statement in VM and in DEFINE LINK statement in VSE. And after peeking into some z/OS manuals, I found that even z/OS is not oblivious to port names. From z/OS V1R9.0 Communications Server IP Configuration Guide: quote Therefore, there are two types of HiperSockets devices: - DYNAMICXCF HiperSockets device or interface (TRLE IUTIQDIO and an MPC group of subchannel devices). The PORTNAME will be IUTIQDxx, where xx = the IQD CHPID that VTAM(R) uses (for example, IUTIQDFD when using IQD CHPID x'FD'). - A user-defined HiperSockets device or interface (TRLE IUTIQDxx and an MPC group of subchannel devices). The PORTNAME is not applicable for this TRLE. In both cases, the TRLE is dynamically built by VTAM. end quote I presume that we have a user-defined HiperSocket here, but in the response to Q LAN DETAILS command for the virtual LAN that Mark defined to test the connection to the VM stack via virtual HiperSocket there is a following line: Adapter Owner: ZOS19NIC: 0724 Name: *IUTIQDFF* That Name: at the end is port name (not device name). If the portname was not used by z/OS, it should've said Name: UNASSIGNED. So which one is it? DYNAMICXCF or user-defined? And why did it work anyway? Maybe virtual HiperSocket is more lax towards the port names than real HiperSocket, because Mark says that the connection over the virtual HiperSocket worked. I also do not want to overly emphasize this port name thing, but I still think that it is worth while clearing. I think Mark said that he copied z/OS from the LPAR to a guest on VM, changed the home IP address and attached the real HiperSocket device trio to z/OS guest as the same addresses that z/OS expects. So I don't think that we will get any further by doing that again, except that this new copy of z/OS will be unmodified. Maybe still worth a try... Your point 1 seems to be in contradiction with the quote above, but I'll believe you have your reasons. Your point about MFS and MTU is great. I can't see nothing wrong in NETSTAT HOME and NETSTAT GATE responses provided in the other thread, but I noticed there that packet size is 57344 (56K) for IUTLNK1 link. How does that work? Does z/OS automatically adjust the MTU of the interface when the device is activated? This would indicate that CHPID is defined with OS=C0 (64K MFS). Mark, when you defined a virtual HiperSocket, you used default MFS of 16K as I see in QUERY LAN response. Try with MFS 64K operand in DEFINE LAN. Just to remove any difference between the real and virtual HiperSocket... Ivica Brodaric
