Putty security
I have a security officer that has raised the issue regarding free [Putty] software. Has anyone encounterd security issues with Putty beyond the Release 0.60? I am looking for documented problems. I am also interested in what I could use as a fee based product to replace Putty.

Re: VM6.2 Network issue
I think you have identified my problem. I was trying to use the same OSA and port connection across two LPARs. One LPAR is using Layer 2 with LACP on the Cisco switch. The problem I now have is testing with another OSA or port to the Test LPAR. This may take awhile due to IOCP and DR issues. Thanks guys for all the help.

Re: Oracle compression
Thanks to all who replied. The DBA was able to identify that the problem was a 'restriction on cross-platform transportable database'.

Re: Missing lin_taped module
Thanks to all who replied to the question. The support center and others confirmed that I needed to rebuild the lin_tape module after each application of a kernel patch. It seems that there are headers included in the module that align with the kernel and will break the module if the kernel is updated. I don't know how I am going to address the issue using SMT to update the images when new patches are available. I guess when TSM breaks I will look at the lin_tape module before looking at anything else. I also had a problem with the permissions on the /dev files. I am using a userid other than root to run TSM and the /dev files are owned by root. The support center found a technote that describes a udev.permissions file that can address this issue. I am trying that now.

FW: Linux preferences
In response to the email... The Oracle DBA indicates that Oracle is easier to implement under Red Hat - I'm interested in what this means precisely, as we should be pretty similar in each environment - we only have the one code set and installer. If there are significant differences that people are finding (on Z) then I'm happy to look into it. I got the following response... Part of the reason for my preference is the Devil you know. I've managed servers with RHAS and RHEL for a number of years. Also, RHEL and RHAS use commands and configurations that are very close to Solaris which I also managed for many years. There are just differences in the way that SUSE works from RHEL and Solaris which are different than the systems that I know well. SUSE is one that I do not know well. The problem that I found with Oracle on SUSE on ZVM is that Oracle did not have a clean install. The base version that was available for SUSE was Oracle 10.2.0.2 and it did not install cleanly on SUSE on ZVM. I did not get a usable database until I installed the 10.2.0.4 upgrades. Also, there was a large amount of manual verification that I had to do because the installation could not properly verify the environment. Now, I'm not sure if this was because of SUSE or ZVM, but it is time consuming and frustrating, regardless. The second problem occurred when I was trying to perform a datapump import using the parameter REMAP_TABLESPACE. This parameter allows me to do a full import of a database and create the tablespaces that do not exist in different locations from the database where the export was performed. Being able to use this functionality is a time saver for me because I do not manually have to create the tablespaces before the import is performed. Some of my database contain many tablespaces and creating them manually before an import is very time consuming. When I tried to use the REMAP_TABLESPACES parameter on the Oracle database that was created on the SUSE OS, it failed miserably. I tried for a day and a half to make it work, but it just did not. I've used this parameter and process on Windows, Solaris, and RHEL OS's with no problems and so I thought SUSE was the issue. However, after much thought it may just be the Z/OS platform that has this bug in the datapump. If it is the platform and not the OS, then it really does not matter which OS is used. If the platform is the issue, then porting new databases to this platform will just be a more manual effort than on our existing platforms and on any other platform that I've used in the past, too.

Linux preferences
I am getting started in the use of zVM and zLinux. I have purchased a license for SLES and have also installed Red Hat under test for an Oracle database. Everything I have installed is currently under test. We are looking at revamping what we have. I would like to pose a few questions. There is the prospect of Novell being purchased by Attachmate. I understand that in the past SLES has been more responsive to the x390 platform. If you were just starting out, would you use Red Hat instead of SLES?? Are there other more pressing reasons to choose one over the other?? The Oracle DBA indicates that Oracle is easier to implement under Red Hat. How hard would it be to manage both distributions??

I just created a Linux guest [TSMSVR01] using a clone master. I verified that the cloned system was good. We then added some FCP definitions and verified they were good. The next step was to extend an LVM and modify partitions. After extending the LVM we encountered a problem. We tried to restore a flashcopy backup to the 202-207 volumes that were taken before the LVM modifications. Now we are getting a PSW WAIT STATE.

I have been in your situatuion before. I would try the Centos for your project since it is very closely related to Red Hat.

zLinux and Tapes
Have read some items in the past regarding TSM, Linux and native tapes. We are currently a zOS shop. We use TSM on zOS to backup our critical networked servers (MSWin) to DASD (2105) and eventually to tape (STK Silo). All I/O is channel attached. We also have a MSWin version of TSM backing up some servers to tapes (STK Silo) via Gresham Software. The tape device is 9940 200GB tape drives using fiber channel. We recently did a Proof of Concept with zVM and ZLinux. The test was primarily to move some Oracle databases to the z10 mainframe. The test went well and we are moving to implement the Oracle database applications on the z10. The test did not include the backup and restore functionality of zVM and zLinux. We are in the process of configuring and pricing a disk and tape solution for the z10 and zOS to include disaster recovery in a second location. The disk is going to be DS8300 in each location connected to replicate using PPRC. The tape solution is giving us something to ponder. The tape we are looking at is the TS7700 VTS. This will work fine for zOS but what about zVM and zLinux. How do I use this solution to backup and restore zVM and zLinux systems for disaster recovery? Is it feasible to use this tape solution with TSM on zLinux? We would like to merge the aforementioned TSM usage to a zLinux platform. Any guidance and direction would be appreciated. Ruddy A.

I can't answer to the hardware supporting the zOS side. There is definitely a VTS, but I don't know if the Linux clients are using it. The other half of our backup strategy, though, is to use the STK 9840 drives attached to our zVM systems, with CA's HIDRO. This gives us image-level backups which we use for disaster recovery.

Re: Backup Restore recommendations
Thanks for all the input. We will be meeting to discuss the solutions mentioned after Jan 5, 2009. We will probably use the zOS solution since TSM is a proven commodity for server backups. Once we have a working solution we may investigate the others. The key is to get something that works asap. -Original Message- From: Linux on 390 Port [mailto:linux-...@vm.marist.edu] On Behalf Of David Boyes Sent: Friday, January 02, 2009 9:31 AM To: LINUX-390@VM.MARIST.EDU Subject: Re: Backup Restore recommendations On 1/2/09 7:37 AM, Harder, Pieter pieter.har...@brabantwater.nl wrote: but TSM tape handling on Linux is so awful and idiosyncratic (not to mention the idiotic fact that TSM for Linux cannot use channel-attached tape) that the price of the extra CPU is probably worth it. I respectfully disagree. I found FCP-based LTO libraries better behaved than our old 3494. And before you ask, I do come from WDSF (aka ADSM V1) and ADSM V2 and originally bought the 3494 with 3590 for the purpose. The price of the extra CPU (and licenses) on z/OS will probably outweigh what you pay for a decent library. We currently run a two IFL TSM and I don't care to think what that would cost me on z/OS. We would have long ago lost the installation to our decentral server group. Good points, but I'd observe that the small incremental price of the additional tape libraries doesn't take into account all the additional costs of actually managing the additional libraries at scale. The cost of creating a new set of operational procedures, having your tape librarians deal with an additional (and incompatible) set of tape technology, and the additional complexity of recovery if you have achieved a high level of automation with the z/OS side is non-trivial, and if you include those costs in the assessment, then the cost case for TSM on Linux is a lot less compelling than otherwise. People are the expensive part of this equation, and the TSM on Linux solution uses a lot more people resources to manage than the z/OS version. I've seen a number of TSM implementatins where the difference was fairly slight after all the additional costs for management were added in. Now, if z/OS ever learns to handle FCP devices or Linux actually acquires a decent storage management capability (watch this space...8-)) (God, it must be a new year. I'm actually arguing *for* a z/OS-based solution.

Backup Restore recommendations
We currently have a VM/Linux LPAR configured for a Proof of Concept [POC]. Our other LPARs are zOS. We plan on using the Linux images to host some Oracle DBs. There are currently no tape drives online to the VM LPAR. During the install of VM and Linux we used a number of methods to initialize and format the DASD [contracted assistance]. We are using minidisks for the Linux images. On some of the volumes we have a zOS VTOC. These volumes cause us to get messages on the zOS system. IEE498I ...LSPACE NON STANDARD OS VOLUME I found on the listserve an item that tells us how to remove the zOS VTOC which should eliminate the message. Our backup and restore [DR] process on zOS is completely automated. We would like the same on VM and Linux. From this I am questioning how we got here and what is the 'best' way to operate in the future. 1. What is the best way to initialize and format volumes to be used for VM and Linux minidisks. 2. What is the best way [considering the Oracle DBs] to backup and restore the VM and Linux images for disaster recovery. 3. Should we use TSM [already installed on zOS] to backup the Linux images to zOS. I know these topics have been discussed on the listserve before but I am looking for what actual users are doing.

Linux DASD Questions
Our Linux Operating System under zVM is up and running, We have installed an Oracle database application on this image. The Oracle database is shutdown or in read-only mode and zOS or zVM performs a flashcopy of the Linux volumes (zVM minidisks. Is this a crash consistent backup of all the Linux DASD volumes? Is there a data integrity exposure and how significant is it when compared to other operating systems like zOS or zVM? The DASD volumes are defined as ext3. Let's suppose that there is a data integrity issue, then how are we suppose to provide Global Mirroring (PPRC-xd) using TPC Replication creating consistency groups every 30 secs? How much capacity do you lose when defining Linux DASD volumes(ECKD) as minidisk under zVM? How much capacity do you lose when defining Linux DASD volumes (SCSI-ZFCP) at FBA 4k blocksizes? Our customer would like to automate backups using the following techniques: Please comment. (1) Quiese or shutdown Oracle Database under a Linux Guest. Flashcopy all Linux volumes (from zOS) Backup all Flashcopy volumes via DFSMSdss Full volume physical dump (from zOS) (2) Provide TPC Replication Global Mirroring for all Linux volumes (3) Provide TSM BA client to provide backups at a file level (4) Is there a Tivoli Data Protection Product for Databases on the Linux platform?

Re: OpenSSH and 'HostBased' Authentication
This is sort of what I have implemented. We are a service bureau for other state agencies. To prevent the agencies from using each other's keys and improving separation I set each agency's key in an HFS user directory with the agency having exclusive permission to that directory. This causes us to maintain more keys but my experience with key management across multiple agencies/users make this worth while. Ruddy A.

Re: Article for z/Journal
I am a graying mainframer. I worked for IBM for 28 years as a hardware servicer, marketing system engineer, and a mainframe contract employee. I am concerned that three universities in my area were deeply involved in mainframe systems education in the past but now focus only on Microsoft products. There is no effort in this area to educate students on mainframes and their potential. I currently work for a state agency that provides data processing services to other state agencies (similar to a service bureau). Although the core applications (finance, welfare, labor) are still housed on the mainframe, there is a concerted effort by the CIO to move all applications to a client/server/web environment. To him this means everything will run on an Intel platform with a Microsoft operating system. Everyone in my work section is 40 years old and up. We recently had five employees leave. One passed away, three retired and one reassign to another area (help desk). Only two people have been recruited to replace these employees. The replacements have been mainframers from other agencies. These agencies have been moving to Intel servers for all new applications. Microsoft has done a great job in marketing their products as the future of data processing. They did this by capturing the education of future programmers and data processing employees in the universities. The personal computer has helped by enabling everyone to think he is a computer expert if he can load and run software on his own machine. The bulk of the people in the data processing industry have little or no contact or exposure to the mainframe. They have no concept of the potential of a single mainframe processor. Their concept is to run each application on a separate server regardless of the interactions of the numerous applications in each and every organization. Whatever happened to having a single source of data so that the data is in sync, up to date and accurate? Some of this has been caused by the cost of mainframe software and the time required developing applications. In today world this is no longer the case. We have desktop development tools for mainframe applications. We can even develop web applications that are more reliable and faster than their Microsoft counterparts. CICS, IMS, and DB2 are still great application environments. Today's application developer just is unaware of their potential and versatility. Thanks for the opportunity to vent my frustrations.

Then, mknod /dev/dasdan b maj min with appropriate substitutions for an maj and min, for each of the nodes you want, will get you started. But you really should not need to do any of this. Just follow the installer's prompts and it should get you there. Rob's comments are gold as well: ensure that the DASDs are online (cat the appropriate online pseudofile in the sys filesystem directory you found; a result of 1 is good) and that the DASD modules are loaded.
