Re: newbie question - convert to full pack minidisk

We turn off MDC at the device level in the system configuration file for our guest operating system minidisks using RDEV TYPE DASD MDC OFF. It would take real performance data to conclude on a bug. It may just be tuning. We know that the defaults for the MDC arbiter are such that many systems will favor MDC and thus cause more paging than the MDC hit rate justifies. If the paging subsystem is not properly configured, then that may keep folks waiting or even abend the system. It's a very popular problem at new installations. When the I/O is not eligable for MDC, the arbiter gets no opportunity to favor that, and you avoid the paging. I would prefer to properly configure MDC rather than disable it. And make sure the paging subsystem is able to handle the load when something else makes you page. Rob -- Rob van der Heij Velocity Software GmbH http://velocitysoftware.com/
Re: VTAM on an IFL?
IBM should have been able to tell you that the instruction set is different on an IFL that on a standard LPAR than runs zOS, CICS, VTAM, etc. --- On Fri, 4/25/08, Thomas Kern [EMAIL PROTECTED] wrote: From: Thomas Kern [EMAIL PROTECTED] Subject: Re: VTAM on an IFL?

Re: HLASM Version
We have recently discovered that HLASM V1R5.0 is now *required* to assemble some of the components of z/VM 5.3 CP ... in particular some that have mods needed by our V/Seg product. I discovered this by inadvertently being accessed to HLASM V1R4.0 while attempting to run my automated maintenance procedure which includes re-assembling all the V/Seg mods ... several will no longer assemble with the older release. Steven: If you have only limited requirements for HLASM, you may wish to check out Dignus' Systems/ASM which is HLASM 1.5 compatible. http://www.dignus.com/dasm/ Jim
Re: HLASM Version
Jim, It's not my/CA's requirement, it's yours/IBM's ... CA's V/Seg has mods to CSECTs such as HCPNSS, HCPNSI, HCPNSP, etc. for AUDIT and name substitution (alias) functions. It's the HCPxxx pieces (not the VSPxxx pieces) that won't assemble. Nonetheless ... thanks for the info. I keep forgetting about the Dignus assembler (even though I'm sure there are a couple of V/Seg customers out there using it).

Compared to a CP, an IFL has one less instruction. If you try to execute it though, you don't get a S0C1, you get a check stop. So, it isn't for technical reasons that IBM rejected the request for the quotes. Rather, it was for IBM business reasons. Some of which may no longer hold sway. I've been told of a number of people that have received special quotes for IBM products that aren't normally licensed on an IFL. Mark Post
Codine a line in Prorfile TCPIP
Greetings Gurus, I need to add a line in the Profile TCPIP file to point to port 2323 as secure. Here is the line and the question follows: 2323 TCP INTCLIEN SECURE The title of the certificate i want to use for SSL to -PLEASE the dear AUDITORS ;TELNET SERVER The name of the certificate is about 60 characters and will force a continuation line. So how do I make that line above understandable by the stack and make the stack accept the title of the certificate? Thanks.

Re: VTAM on an IFL?
Which brings up a different tangent With the IBM z10, you can mix standard and IFL engines in the same LPAR. So, if you put all your engines in the same LPAR, what does that do to licensing of 390 software that can also run on an IFL? And then on the Linux side, would you then get charged for the 390 engines? i.e. DB2/UDB and Oracle Tom Duerbusch THD Consulting Lee Stewart [EMAIL PROTECTED] wrote: Hi...

Re: Hipersockets - xposted to VM-L IBM-Main

The OSA connection on the VSWITCH works, the real Hipersockets do not. Sorry if I misunderstood. If HostA and HostB are on the same HiperSocket chpid and cannot ping each other, then there is a routing problem (bad IP address, subnet, or subnet mask, or incorrect dynamic route). As always, draw a picture and make sure the picture is legal. I've seen people with syntactically perfect configuration files but a configuration that violates the Natural Laws of Networking. Then display the routing table on both HostA and HostB to see if they are consistent. Alan Altmark z/VM Development IBM Endicott

Re: VTAM on an IFL?
We wanted the full-featured RSCS 3.2 that we were (are) running to communicate with z/OS, so that important data (erep, monitor, accounting, backup jobs) could be transfered to z/OS via NJE for processing. We have shrunk enough that VM data just isn't worth anything anymore. None of the bosses has decided about paying for your full-featured feature now, so you may be out of that money too. Data just isn't supposed to go into or out of VM anyway. /Tom Kern Alan Altmark wrote: On Friday, 04/25/2008 at 08:33 EDT, Thomas Kern [EMAIL PROTECTED] wrote: We requested the 'special quote' when we first looked at purchasing a z890.
