Restarting DB2 and WAS with crontab
We are Suse9,Z/VM 5.2 shop. I'm having a small problem and am wondering if someone can help me out. I've written / integrated some scripts to bring down DB2,WAS,CM, then backup/zip the files up ,and restart the systems. All the scripts work fine separately and together if I'm am logged on as root, but if I submit the same script using crontab everything BUT the startup works. What happens is the system looks as if everything is up(per the task count) but we are unable to log on to our DB using WAS. All we then do is su into root run the startup procedure and everything works. All the proper calls /paths are in the scripts and I have even placed roots' path in the path stmt in /etc/crontab. I'm really at a loss. thanks Larry __ Do You Yahoo!? Tired of spam? Yahoo!

Thanks, RF Robert: I had a customer do this early this year, more for testing than anything else. It works quite well with one note: Use an active/passive configuration ONLY if you have only one IFL. If you have more than one IFL then you can use an active/active configuration. This especially true when doing a database load as an active/active configuration ends up swapping between the two Linux images for every record loaded.

THis sounds like a difference in the process environments. When you log in, /etc/profile and a number of other scripts are run for you and these set up many environment variables. But when a cron job is started, none of that setup occurs. You can either make your scripts source those startup files, or figure out which environment variables are not getting set and run those. Because this is DB2, the most likely thing that is not getting run is the $HOME/db2profile script. This sets up a number of environment variables that DB2 requires to do anything, such as DB2INSTANCE. Try putting this command at the beginning of your script: source $HOME/db2profile and see if that doesn't fix things. If not, use env(1) to dump out your environment when logged in and from the cron job, and compare the two. - MacK. - Edmund R. MacKenty Software Architect Rocket Software, Inc.

Is anyone connecting to a Hitachi SAN-box with FCP NPiV?
We wanted to connect to our SAN-box using FCP NPiV for either open-systems server storage (using TSM) or to implement the new GDPS function of DR-mirroring the open-systems storage. However, the IBM representative we talked to said that they couldn't support us if we ran into any problems (either with connectivity or possibly data corruption) unless we were connecting to an IBM box. It kinda scared us off the idea. Is anyone successfully using non-IBM storage (especially Hitachi) with FCP NPiV?

Re: Restarting DB2 and WAS with crontab
We are currently running scripts through /etc/init.d/rcX, which, I realize, is something different, but we also run as wasadmin using a stored userID and password. Here is the script we use, although ultimately simple, it works. Not sure what the CM product is. We have DB2 and WAS on separate Suse 9 images. DB2 is one image at present, and WAS is a cluster of 3 with a shared binaries image and one deployment manager server. echo "Starting IBM Websphere Application Server on Linux11.." su - wasadmin -c /wasprofiles/profile/Linux11Custom/bin/startNode.sh; su - wasadmin -c "/wasprofiles/profile/Linux11Custom/bin/startServer.sh linux11AppSrv01;" echo "... start up complete for Websphere Application Server on Linux11"; exit 0 echo "Stopping IBM Websphere Application Server on Linux11..."; su - wasadmin -c "/wasprofiles/profile/Linux11Custom/bin/stopServer.sh linux11AppSrv01;" su - wasadmin -c "/wasprofiles/profile/Linux11Custom/bin/stopNode.sh;" echo "... shutdown complete for Websphere Application Server on Linux11"; exit 0 DM is simply stopManager.sh Daryl On 10/23/07, LJ Mace <[EMAIL PROTECTED]> wrote: > > We are Suse9,Z/VM 5.2 shop. > I'm having a small problem and am wondering if someone > can help me out. > I've written / integrated some scripts to bring down > DB2,WAS,CM, then backup/zip the files up ,and restart > the systems. > All the scripts work fine separately and together if > I'm am logged on as root, but if I submit the same > script using crontab everything BUT the startup works. > What happens is the system looks as if everything is > up(per the task count) but we are unable to log on to > our DB using WAS. > All we then do is su into root run the startup > procedure and everything works. > All the proper calls /paths are in the scripts and I > have even placed roots' path in the path stmt in > /etc/crontab. > I'm really at a loss. > thanks > Larry > > > __ > Do You Yahoo!? > Tired of spam?

Thanks, RF Works as documented, or as well as RAC ever does. For it to be any use for survivability, you really need to do it in a CSE environment with two systems or LPARs and split the cluster members across the two instances. Shared DASD is necessary, which is complicated to set up and maintain with FCP disk. Networking really needs to do layer 2 VSWITCH with VLANs managed by goodly sized switches between the machines to do the heartbeats efficiently. Short version: it's as much of a PITA to manage as RAC is on discrete systems. Given that the underlying infrastructure (CSE, VM, System Z) is orders of magnitude more reliable and stable than the discrete system approach, it's probably overkill for anything short of absolutely critical systems (which, IMHO, are the principal justifying reason for z/OS parallel sysplexes, and once you have a parallel sysplex in play, we're talking about a whole 'nother level of RAS, and RAC is pretty pathetic in that arena). -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390

Re: SAN NAS
A NAS acts like a file server. It contains its own filesystem and usually connects to a LAN, not a dedicated network. Often a NAS communicates to the client using SMB, and NFS. Many of the lower cost NAS are just a Windows system that does not let you log into it. A SAN does not have a filesystem.

The difference, roughly, is whether your data is presented as files or as blocks. NAS tends to be some sort of storage appliance that presents an NFS (or SMB, or other network filesystem) interface to the data, while SAN is generally presented as a block device. SAN is less likely to use IP as the transport, though certainly there are things like iSCSI.

Re: SAN NAS
Connectivity method and transport protocols. NAS are attached via data networking technologies such as IP or other data network transport protocols, usually employing standard networking equipment used for ordinary networking transports. Usually gig Ethernet over fiber or copper with dedicated segments for storage traffic. SANs are accessed via storage networking techniques which do not involve IP or other data network transport protocols and use specialized switching equipment optimized for storage networking protocols. It's arguable whether performance is any different these days (in fact, with multipath links, NAS may be faster these days).
