One of the pros for running DB2 on zLinux is that the version of DB2 for zLinux is under active development by the IBM DB2 group and supports more features and capabilities than does the DB2 for z/VM.

Re: SFS problem
I do not believe that this is the problem. I was giving you information on the failing job that I am most familiar with. Other jobs that fail are submitted to VMBatch by the ID that also owns the SFS directories. FYI, VMBatch is the IBM VM Batch Facility Version 2.2, I was not aware until recently that there are other products also known as VMBatch. If this has caused confusion, I apologize.

(SECUSER is an old term). Diag 88 provides the ability to link minidisks and perform userid/password validations (if the issuer has appropriate authority). An interesting usage note for this is that DIAG D4 does not change the userid associated with any existing (already active) SFS connections. This is because it is a CP function and manipulates the VMDBK. Once set, future connections (via APPC/VM Connect) will utilize the Alternate ID. ... This is why severing all connections prior to setting the AltID will fix this type of problem, because CMS will (re) connect and use the AltID. If this is Nora's problem, an easy work around would be wrap the job with an exec that uses DMSGETWU and DMSPUSWU to set a new default work unit that contains the appropriate user, then run the job from the exec, then finally reset with DMSPOPWU.

With SFS, this can lead to unexpected results when a prior batch job leaves the worker with a connection to the filepool under a different user's id. If the job ordering/selection of batch workers is somewhat random, you could see the outcome that you're experiencing (sometimes it works, sometimes it fails).

Mike, Yes, I checked out the message. The thing is, the job runs nightly, and only fails intermittently.

Re: VM DB2 7.3 question
Do you have Control Center? It's an IBM Licensed Program Product. If so, select Option M from the main menu. Add a Monitor, and select User Locking. This does have the side effect of displaying messages any time locks are encountered, so check out the appropriate notify parameters. We monitor the locks on the production database every 5 minutes, and generate a report weekly. I review the NLRBS and NLRBU usage to see if changes are needed. The report does not show you who had the problem, but at each monitoring interval, it shows you the number of NLRBS allocated, the number used, and the number free, and the number of NLRBU allocated, and the maximum used by the LUW.

more RAM for DB2
Cross-posted to VM/ESA and DB2 lists. I'm running DB2 7.5 under z/VM 5.4 (both are the current releases). We have a brand-new z10 processor. My Systems Programmer has offered me 1 Gig of RAM, up from our current Virtual Storage of 384 Meg for the production database. I'd like to take advantage of this extra RAM, if at all possible. I've been using the Diagnosis Guide to see how to alleviate the problems of not enough storage, thinking that I can work backwards from that. I can see that I've got constraints on my current use of buffers per user, and I can increase that number. I'd like suggestions on other parameters to research, as well. TIA, Nora Graves

Re: LOGONBY
And it makes it easy to revoke privileges from a user: just remove the LOGONBY authority. This is handy in an environment where roles change frequently. And if the person leaves or retires, deleting the User ID takes care of all access, without scrambling to remember which seldom-used accounts that the person may have used occasionally.

So then you only add certain user ids to do LOGONBY for this user id correct? Think of it more as a role: you are assuming the role of TCPMAINT, using your own login credentials to validate your claim to the role. The idea is minimum privilege; shared ids should not be directly logged into, because you lose the audit trail of who did what. You give individual ids minimum privilege (essentially with the combination of LOGINBY and PROP, there's rarely a real reason for any individual id to have more than class G), and they authenticate to the shared ID when they need to do something more powerful, or an extended string of things that require privileges or access to files w/o having to jump through a lot of maintenance-intensive hoops.

Another consideration is DB2, if you run DB2 for VM/VSE. We have successfully written log archive files to disk, but for the full archives apparently tape is the only thing it will accept.

Re: Huge LASTING GLOBALV file for DB/2 servers
We've been running DB/2 for VM since Release 6.1. We're currently on DB/2 7.3 under z/VM 4.4. Our current LASTING GLOBALV is 137 lines long for SQLPROD, and it doesn't have any duplicates in it. We do not have the SQLINIT step in our PROFILE EXEC for any of the databases. We also do not log the databases off very frequently. However, they do get logged off enough that at least some duplicate entries should have occurred if that were the cause. On my personal 191 disk, I don't have any duplicate entries, either. I issue multiple SQLINIT commands each day, switching between various databases. However, I do not issue the command through my PROFILE EXEC. I'm not a systems programmer, so we've about reached the limits of my knowledge. :-) Nora Graves [EMAIL PROTECTED] Main IRS, Room 6513 (202) 622-6735 -Original Message- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Ed Zell Sent: Thursday, December 21, 2006 2:02 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Huge LASTING GLOBALV file for DB/2 servers We are running DB/2 for VM 7.4 on z/VM 4.4 at service level 0501.

In looking at the LASTING GLOBALV file, there are many lines with SQL/DS RELEASE;7.1.0 and SQL/DS RELEASE;7.4.0 so that tells me this has been going on a long time and I am just now noticing it.
