A mainframe operating system is networking software infrastructure that allows a mainframe computer to run programs, connect linked machines, and process complex numerical and data-driven tasks. Modern mainframe design is generally defined by redundant internal engineering, extensive input-output facilities, strict backward compatibility with older software, high hardware and computational utilization rates and high stability and reliability. Well-known operating systems include IBM z/OS, z/VM, zTPF, z/VSE, OS/390, and their predecessors, along with MCP for Unisys ClearPath, and NonStop OS/Guardian on HP/Tandem, and questions regarding the IBM midrange operating system called IBM i, OS/400, and i5/OS.

I have a SYSMDUMP which is transferred from a mainframe system in to a unix system.
I need to read that SYSMDUMP through IPCS in my mainframe machine.
From the unix system I have transferred the dump to my mainframe (Z/OS v 1.4) machine. To transfer the dump from the unix machine, I did a binary

FTP transfer.

The characteristics of the dataset which stores the SYSMDUMP is given below :

Data Set Name  . . . :SAMPLE.SYSMDUMP                          

General Data                          Current Allocation
Volume serial . . . :W4CIC1     Allocated cylinders :200  
Device type . . . . :3390            Allocated extents . :1    
Organization  . . . :PS          
Record format . . . :FBS          
Record length . . . :4160        
Block size  . . . . :24960         Current Utilization        
1st extent cylinders:200          Used cylinders  . . :2    
Secondary cylinders :100        Used extents  . . . :1    

Creation date . . . :2005/09/07
Referenced date . . :2005/09/07
Expiration date . . :***None***        
                   
When I tried to open the SYSMDUMP using IPCS, IPCS fails to open the SYSMDUMP and gives the address space as RBA.

When I try to browse the SYSMDUMP it throws the following error :

IKJ56650I TIME-00:06:08 AM. CPU-00:00:01 SERVICE-8162 SESSION-00:04:03 SEPTEMBE

On my police scanner, a police officer was trying to run a plate to the dispatcher. When the dispatcher tried to run the plate, she said "DMV is down" so that means she could not get an address of the person who owns the vehicle.

Now, does that mean that the DMV servers (can be a Mainframe, AS/400, i5os, Windows..who knows) are down and once these servers are down, I would assume that they generate something like a Z/VM CP message stating the server has malfunctioned or suffered a "hicupp" in the network...And those messages (if there generated), are then managed by a Computer Operater that works for the City as a Systems Operator...Now, tyhe computer operator then forwards that error message stating that the DMV or one of the DMV servers is down to a Programmer....who then resolves the issue...

Normally, when I hear a dispatcher saying that the DMV is down is actually back up within minutes...I actually want to know what goes on behind the scenes when the DMV system is down.

What I said above, is that correct how they resolve the issue?

I have been listening to my local police on my scanner radio for years now since I am a "scanner freak". Since police have the authority to gain access to  someones DMV files by running the license plates and license number of course, it has to get it from a server or database program from  the DMV .

I have been always wondering about that. What Operating System or Server does the DMV use to store all of the DMV records and plates when police runs them through their dispatch center and then from the dispatch center they of course get the info from the DMV database? I know the dispatch uses the CAD System for emergencies and for other stuff. But what does the DMV use?

I have alot of guesses below and I need you to correct me if Im wrong (if someone knows):

IBM Mainframes running i5-OS, AIX, Linux...
iSeries AS/400 servers
Windows NT Server (which I doubt)
Novell NetWare
Windows running MySQL database
UNIX running ORACLE

Well, I have the my guesses above.

I would like to ask an expert on what type of servers do they keep all of the billing statements when using a credit card transaction? Also, what type of OS do they use to handle this? I am very interested on how this works. Do they use CICS, DB2, or what type of application or OS do they use for storing credit card billing statements? Does it depend on the type pf bank's IT department? And also, I would feel sorry for the person who is doing backups on these servers with that kind of information.

And with that, how would such a backup process done on such sensitive data on these servers? Is it a incremental, weekly, daily, or yearly backup? I am assuming that they use some type of robotic tape backups. I used to work for the city, and we spent billions of dollars for our IBM robotic tape system with each tape or diskette being 60GB in size of data on it....

Thank you

Hello to everyone -

I am just wondering - If running SUSE Linux Server for zSeries and S/390 Mainframes under the GUI (not really recommended) does the looks of the GUI the same as running SUSE as a desktop version?

I would like to see (If anyone can post) a screenshot of SUSE Linux Server's GUI for the Mainframes. People had told me they run it as Runlevel-3. But does the GUI look the same as If I were running SUSE Pro 9.3?

Thanks

We have a requirement to implement Sysplex on MVS mainframe. Requires help to do it.

Does an OS/390 mainframe have any tools for unpacking files like unzip or tar?

I want to ftp a grp of files in a single zip/packed file, but I'm not sure what type of packing format it should be sent in.

I keep hearing about this program called VMWare, and since I need to run an old DOS application in my line of work, I thought perhaps I should look into it more.  I don't, however, want to pay $400 for a program that causes constant crashing or XP headaches.

I like the idea of being to run Win98 and XP at the same time, without having to create a dual-boot system.  But, my question is, does it really work??

Thanks in advance for all comments, links, praise, criticisms, etc.

Hi Guys,

Can someone provide me with answers to these questions.....

a)What are the different ways to have remote mainframe connectivity and which is most suitable and preferred ?
 
b)What are the tools required for transfer of files between Mainframe to NT & vice versa? (EDI files to be transferred)
 
c)Is there some sort of scheduler for all such file transfers?
 
d)2-3 lines about terminal emulator / work bench etc.
 
This is urgent please reply as soon as possible.

Thanks,
Vinay

I have a file that contains a packed decimal value and I want to ftp the file up to the mainframe, but during the ftping, the format of the packed decimal field becomes corrupted.  How can I get around this or resolve this?

Thanks in advance.
