Re: MONWRITE files
I collect these records for CPU statistics: ddrr (domain / record) : 00** ddrr (domain / record) : 01** ddrr (domain / record) : 0403 ddrr (domain / record) : 0404 For storage i think you need to add some record types from Domain 3. The CP monitor records can be found here: http://www.vm.ibm.com/pubs/ctlblk.html I had to include domain 0 and 1 because we also get the number of CPUs out of them, and - if i remember correctly, i had to include some control information too because MXG was not able to import the data without these control information. If you are interested in the exec, please let me know. at least it can be taken as a sample how to extract the monitoring data, it was a bit of a puzzling work because i did not find a documentation about the monwrite file format, i had to find out by myself how the logical monitor records are physically organized.

Question on ordering z/VM 5.3
I'm a newbie to z/VM. We want to migrate from z/VM 5.2 to z/VM 5.3 My background is z/OS and have placed many orders via ShopzSeries for upgrades. Typically id upload a bitmap of my products installed from SMP/e and id check off what I need to order. I just logged on ShopZseries and don't see the exact same thing from z/VM. I see I can upload a bit map (via maint id) for fixes but can I do the same to place an order? How do most people do it just order the DVD and products like RACF/RSCS etc separate? Thanks in advance.

Re: Question on ordering z/VM 5.3
Andy, Products like RSCS and RACF (on z/VM 5.3) are actually shipped with the product. So if you order z/VM 5.3, you will get them on the DVD. If you are licensed for the products you can activate them for use after installation. [EMAIL PROTECTED] wrote: I'm a newbie to z/VM.

Re: Question on ordering z/VM 5.3
Andy, RACF, Dirmaint, Performance Tool Kit, and yes RSCS do come with z/VM5.3 but remember RSCS for z/VM5.3 is now a feature and not a program product and is priced differently it is a different choice on the SDO order. You will get z/VM 5.3 and its feature products and an SDO tape with program products.

Re: Physical Planning Manuals
Peter--If you still need the power requirements for a 3480-A22/B22, this is from our CE The b22's get their power from the a22. Voltage (AC, 3-phase, 4-wire, 60 Hz): 200V #2733 208V #9903 220V #2800 240V #9915 He also included a url, but possibly, it's IBM internal use only, because I couldn't get in. I assume the numbers on the 200V and 220V lines are Russell and Stowe part numbers, probably one of them being the male connection and the other the female connection.

Re: CMS VSCREEN
The exec I am trying to modify is the client in a client/server situation. Both client and server userids nucxload assembler code that uses VMCF for communication. 1. The client exec uses VSCREEN to 'put up a screen' 2. The user/client enters a command which is then sent via VMCF to the server. 3. When the response comes back the client's VSCREEN WAITREAD 'wakes up' because of the VMCF interrupt. The client's nucxloaded code then stacks the reponse. At this point the WAITREAD.1 is set to UNKNOWN. 4. Client code then displays the response on the VSCREEN. I have re-written the server in RXSockets and want to massage the client code to use RXSockets as well. My problem is that when the server 'sends' the response I have no way of telling the client to 'wakeup' and receive the data.

You put up the screen/menu with the SMSG option - if someone(server) sends you an SMSG you wakeup and can take action. I am looking for a way to do this with VSCREEN. If you can tolerate the client idle waiting for a response, then have the client code open one TCP socket to the server for use in transferring data and a second UDP socket as a signaling mechanism. Do a read from the UDP socket when you want to wait for a response. The read will block if there is no data available, and will wait until something arrives, and then return. You can send your data on the first TCP socket, and just use the second socket as a data set ready indicator (to borrow a term from serial I/O), omitting the message and wakeup components entirely. When you want to wake up the client, send a single UDP (or use TCP if you want to be paranoid) packet from the server, and the client will wake up from the blocking read and go on. You can then process and/or discard the DSR packet as you wish, and read the real data from the other socket. Of course in a pure REXX program, that implies the client comes to a complete halt on the blocking read. If it's a pipes app, then (I think) you block only on the thread that is doing the blocking read.

Number of IFLs to zLinux guests
Hello All, Is there a golden rule about the number of IFLs to support production Linux guests?

Re: Number of IFLs to zLinux guests
z9 ECs here and a z10, but I'm not counting him yet... In prod - we have 45 or so guests on 18 IFLs In test - we have had 100 or so guests on 2 IFLs. So, the ratio is either 50:1 or 5:2 :) You can see why everyone says it depends. If you can get the testers to play well together (wiki page coordination is what we do), I think one could have a ratio to work with in test. Prod is going to require measurement and planning :) Memory is usually a bigger issue than CPU. At least with CPU you can prioritize things so not all feel it.

Re: Number of IFLs to zLinux guests
We're running about 40 Linux guests on a total of four IFLs, spread across two LPARs and CECs. Roughly 20 guests in each LPAR. We're about to add an additional IFL to each LPAR, not for capacity, since we're normally running at about 10 - 20 percent, but to handle the case where a single rogue guest consumes everything it can get for awhile. We'll continue to build one and two virtual CPU guests, but have the third engine to avoid allowing a single guest with dual virtual CPUs from eating the entire system. -- Robert P.

Re: Number of IFLs to zLinux guests
You could play it politically safe and start with the same sort of ratio that your organization's Windows Virtualization people are using (http://communities.vmware.com/thread/128660?tstart=30). Then when you see that your processors are not fully utilized and you still have paging capacity, you can add more guests while the Windows group needs to ask fo r more hardware. /Tom Kern On Wed, 19 Mar 2008 14:20:19 -0500, Harris, Nick J.

Re: Number of IFLs to zLinux guests
You can definitely run short of CPU if your guests are CPU intensive. we have 40-50 guests on 2 z990 IFLs see http://www.linuxvm.org/Present/SHARE110/S9284ps.pdf see page 11-13 This e-mail, including any attachments, may be confidential, privileged or otherwise legally protected.

You have to run MAKESITE to update HOSTS ADDRINFO and HOSTS SITEINFO, since the clients only read the *INFO files. That hasn't been true for quite a while, Mark. z/VM 5.1 introduced ETC HOSTS. It does not require use of MAKESITE; the *INFO files are used only if no ETC HOSTS is available. (Death to *INFO files! Death, I say!) Thomas said: I recently had a change to ETC HOSTS but I can't find a way to get TCP/IP to recognize my change. Is there a way, other that recycling TCPIP, to get the stack to reprocess the ETC HOSTS file? Recycling of the stack is not required. Just put the updated ETC HOSTS on the 592 disk and recycle the *application* server (to get it to re-access the 592). The file is read by the resolver, not the stack.

Re: ETC HOSTS question
It appears that is correct. It looks like it has to be on a mdisk that can be accessed by whoever is requesting the address resolution. Anyhow I put it on 592 and my problem was solved.

No. I understand all shops are different and 'it depends' applies...but we are curious as to the ratio of IFLs to Linux guest in other shops. The question that comes to my mind is why would you care? My reaction is that you're trying to manage performance and capacity by gut feel and rules of thumb. If so, that's a good way to ensure failure at some point. You need the proper tools to monitor both and make rational, fact-based decisions. Are there any shops out there running zLinux guests in production under z/VM with two or less IFLs besides us? We have four production Linux guests and twenty one test Linux guests supported by two IFLs on a z9BC. If you are experiencing bad performance, you may nor may not need to add capacity, which is where having a good monitor can help you be sure. If you're having good performance, for all you know you could put several hundred guests on those two IFLs. Or, maybe the next test system will crater you. If you don't have good measurements, all the rules of thumb in the world won't help you. Mark Post
