We have never used it, but maybe it could be interesting for you. z/OS V1R7.0 Comm Svr: SNA Resource Definition Reference URL: http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/F1A1B650/5.7?DT=2 0050720144034 5.7 Message-flooding prevention table The message-flooding prevention facility identifies and suppresses duplicate messages that are issued in rapid succession. This reduces the possibility of duplicate messages flooding the operator console and concealing critical information. VTAM bases its suppression on the time interval since the message was last issued and on the similarity of variable text in the original and subsequent message. For each candidate message, the message-flooding prevention table contains the criteria that must be met before VTAM suppresses duplicate messages and whether suppressed messages are sent to the hardcopy log. The suppression criteria include the amount of time between the original and subsequent messages, and an indication of which variable text fields are to be compared. If the message is reissued within the specified time interval and the specified variable text fields contain the same information, VTAM suppresses the message etc. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

If you specify this parameter, FTP uses the translation table in the user_id.data_set_name.TCPXLBIN data set, rather than the standard translation table provided with TCP/IP (hlq.STANDARD.TCPXLBIN). The hlq.STANDARD.TCPXLBIN data set is never used if you specify the TRANSLATE parameter. If user_id.data_set_name.TCPXLBIN does not exist, FTP uses hlq.data_set_name.TCPXLBIN. If neither data set exists, or if they were incorrectly created, FTP ends with an error message. Since the TRANslate parameter also dictates the search order for DBCS translation tables, you might wish to use a customized DBCS translation table but not require a modified SBCS translation table. If this is the case, copy hlq.STANDARD.TCPXLBIN into the nonstandard TCPXLBIN translation table data set to ensure FTP will start. - I believe it is only the data_set_name part that you need to specify.

Re: Adding LPARs without POR
I don't understand two things: 1. Who needs hundreds of linux servers on a single IFL, even if it is possible? 2. Inactive partitions allocate no physical memory, but if I want to activate them I must have memory available to accomodate their needs. That means I must have the capacity although the lpars are still inactive. So, indirectly they do eat memory.

Re: Adding LPARs without POR
No, until they need the memory, you can give it to other LPARs. We haven't reconfigured the storage element offline in an active lpar for a long time, but years ago we had a need once and it did not work, because that was a CICS allocated storage and stopping it was the same as IPL. Alternatively you can add memory concurrently before activating the new LPARs. I don't believe there are many fans of it here.

Re: Enhanced Catalog Sharing
What is the gain or the advantage of using ECS. From an old redbook (Enhanced Catalog Sharing and Management, SG24-5594-00, July 1999): --- When CAS opens an eligible catalog and the system is in catalog sharing mode, as described in Activating ECS on page 18, the integrity VVR is copied into the Coupling Facility structure. Once this occurs, the systems that share the catalog do not have to read the VVR to detect change, as they will receive notification from the Coupling Facility. Also, the requirement to ENQ on the resource is removed because the Coupling Facility architecture incorporates the necessary locking. --- and --- This is an elegant solution to the performance issues. The elapsed time is reduced because GRS is no longer used, and the number of I/Os is reduced because the VVR does not have to be read. Also, the new function fits smoothly alongside the existing reliable and robust code, which will still be used for non-ECS catalogs. Non-ECS catalogs are now described as being in VVDS mode, which indicates that the VVR is being read from the VVDS. In the rare circumstance of a connectivity or Coupling Facility structure failure, the ECS catalogs will revert to VVDS mode, allowing the integrity of the catalogs to be maintained across such a failure. --- Zaromil -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Re: CF usage at DR location
- snip - I have a full test this weekend, so hopefully will have some of this ironed out. I am going with a newly formatted CFRM dataset and retaining all the other COUPLE datasets. If I use a new CFRM dataset, where is the CF policy information stored? I was thinking it was stored in the XCF COUPLE dataset as how would z/OS know how to format the CFRM dataset when coming up?

If you want to use a newly created CFRM couple dataset, allocate it on a mirrored volume, write the policy you want into it, and that should be it. Just don't use it before the test. But, if you are already testing, you could first try to IPL with the old CFRM couple dataset, having a policy with all CFs in it. If it does not work, take the new CFRM dataset.

Re: CF usage at DR location
- snip - We were early users of XRC circa 1998. In our first few tests, we had lingering problems because, with mirrored CFRM data set, the newly IPLed systems could never get over the loss of the two CFs left back in the smoking hole. They were convinced that some magic would bring the lost CFs back to life. I put the problem to Curt Jews at SHARE--in SCIDS of course--and he recommended *not* to mirror the CFRM data set. Voila. The crux is to IPL the first system with an empty, freshly formatted CFRM data set. There is now no trace of the lost CFs ever having been in use. - snip - I remember a lot of problems in case of a failing CF or migration to new CF(s) in the 90's. But, the functionality is much better now. Recently we moved a sysplex from 2084 to 2094 (four systems and two ICFs on the same CEC). We did not use a freshly formatted CFRM couple dataset. Instead, before the upgrade we activated a new CFRM policy, the old policy containing CFs CFOLD1 and CFOLD2 and the new policy containing CFs CFOLD1 and CFNEW2. After the successfull upgrade we activated the actual CFRM policy, containing CFs CFNEW1 and CFNEW2. That worked without problems and we had a failback possibility all the time. And as you wrote, there is now no trace of the lost CFs ever having been in use. Neither we used freshy formatted (new) XCF couple datasets nor freshly formatted (new) CFRM couple datasets.

Re: HDS backup process
This thread has begun with a PPRCopy question. I am not sure if this two parts of Bruce' mails (not to cite John and Ron) talk about PPRC (Truecopy) or Flashcopy (Shadowimage). I wasn't able to see any of these features in our z/OS 1.7 PPRC environment using HDS 9980. - snip - You don't need to lose the relationship to do the backup. You probably want to backup a point-in-time copy of the volumes, so you can just SUSPEND the PPRC relationship. This freezes the copy and makes it read/write so you can relabel (CLIP) it. After the backup, you can RESYNC the PPRC copy, which just copies tracks updated since the SUSPEND. - snip - Supposing we do it in a z/OS 1.7 system I don't understand how is it possible to clip the secondary volume. I get the info about the device being a PPRC secondary device. Even if I take the primary volume offline, I get the same kind of message if I try to take the secondary volume online. Bruce wrote: - snip - I believe that RESYNC will copy any tracks which have been modified on the source OR target. - snip - The other thing that I don't understand: To be able to write on the secondary volume, I suppose I have to use CDELPAIR or at least CRECOVER. If I use CDELPAIR, I can not RESYNC anymore. If I use CRECOVER the secondary volume switches in the SIMPLEX status, so how comes its bitmap is updated?

Re: CF usage at DR location
- snip - as I wrote, you actually CAN mantain your CFRM couple datasets, with your policy, provided that your policy comprises both primary and DR CF; what you need to have for DR purposes only, is an empty and initialized XCF COUPLE dataset (easy to do once and to forget) and a PARMLIB COUPLExx member, to be used in DR situations. ...snip ... I was hoping to use the existing COUPLE dataset and the existing policy. Since these datasets will be PPRC mirrored I was hoping to find a way to not maintain 2 separate policy definitions so that the day-to-day policy definitions would be automatically used at the DR location. ...snip ... - snip - You could try the following: If you do not mirror the primary XCF couple dataset you could dedicate a volume for it and use the same dataset name and volser in the DR site (the volume - and so the primary XCF dataset - is not mirrored). That way you can use even the same COUPLExx.

The TC390 R-VOLs must be offline during normal TC390 operations. Note: TrueCopy – S/390® provides a special R-VOL read option (see section 2.2.4) which allows read-only access to the R-VOL while the pair is suspended. If you need write access to a TC390 R-VOL, you must delete the pair. 2.2.4 R-VOL Read Option For additional flexibility, TrueCopy – S/390® offers a special R-VOL read option. The Hitachi Data Systems representative enables the R-VOL read option on the RCU (mode 20). The R-VOL read option allows you to read a TC390 R-VOL only while the pair is suspended, that is, without having to delete the pair. The RCU will allow you to change only the VOLSER of the suspended R-VOL, so that the R-VOL can be online to the same host as the M-VOL while the pair is suspended. All other write I/Os will be rejected by the RCU. The MCU copies the M-VOL VOLSER back onto the R-VOL when the pair is resumed. When the R-VOL read option is not enabled and/or the pair is not suspended, the RCU rejects all read and write I/Os to a TC390 R-VOL. Note: If you need write access to an R-VOL, you must delete the pair.

Re: Allocated volumes after the power loss in the storage subsyst em
You normally don't see this, but this still does not mean it cannot occur. Were the devices really offline? I do not believe they were offline in the system (another thing to check during the test!), but they were offline in the real world. The UCB Online, Alloc, Busy etc. indicators are independent bits, that do not have a fixed relationship, however z/OS ensures that things happen in a certain order and so there are combinations of bits that you will probably never see. However, you are in an abnormal situation, so you might see rare combinations now. OLTEP e.g. was one application that allocated an offline device and so the UCB status was really and correctly offline/allocated. GDPS Hyperswap does it, too.

Re: Allocated volumes after the power loss in the storage subsyst em
Kees, are you testing disaster situations We are a GDPS site, 3 production parallel sysplexes, 2 - 3 sites, PPRC and Hyperswap, with unplanned Hyperswap in test parallel sysplexes (two of them). A smaller part of production volumes is not mirrored (customer's decision). Because of GPDS we do test outages quite regularly in our test sysplexes, simulating an outage mostly through generation of messages. The real storage subsystem outages are quite rare, because we need the help of the vendor's technician (field engineer?). In the production there are regular annual disaster tests for a whole site, but not with power outage (lot of non-mainframe servers could have problems establishing normal work). or did you really have a complete power outage on a storage device and was the device configured sufficiently redundant and if so, how could this happen? There was a UPS problem, it registered(?) anomaly in the electricity and itself and cut the electricity on the site (that was my understanding). I came later in and had to do only with the problems on the mainframe side. The simplex devices (that is, not mirrored) were not critical for the production (the applications could go on with the half of the capacity). The only problem was that applications hanged as result of these allocations. Luckily, it happened in the night, and as the electricity came, we had the access to all the volumes again - no problems. Well, as Ed Finnell wrote: when the subsystem gets IML'd (takes forever under normal circumstances). Normally, it is a primary GDPS site for one production sysplex, but at the time that was our secondary site, so we lost only the systems running there. Actually we had seen this behaviour a few years ago, as we had done a lot of basic GDPS functionality testing: I/O intensive job writing to two different volumes on two subsystems, one is powered off, you get only the IOS002A message, the job is (if I remember correctly) all the time in in SDSF DA, no CPU-time change, then we activate the second box, job writes on as nothing happened. At that time we thought it was a nice feature g.

Re: REXX Execs to help in String SRCH

Re: Using symbolic in JCL
Walt, -- snip -- Unfortunately, since different systems in a sysplex (or sharing the spool) could have very different times and dates, they could get very unexpected results if we let those symbols be used in batch job JCL. Suppose the job converted on a system where the date is today, and ran on a system where the date is several days, or weeks, ago. (The normal case is to have them very close, of course. And the more likely unusual case is to have them simply a few hours off. But nothing requires that the dates/times be anywhere close across systems, that I know of.) -- snip -- According to Setting Up a Sysplex: Similarly, for MVS to monitor and sequence events in a sysplex as you intend, time must be synchronized across all systems. and MVS compares time stamps from the TOD clock with time stamps recorded in the sysplex couple data set. If time stamps in the couple data set are later than those specified by the incoming system, MVS determines this is an error and does not allow the system to join the sysplex. How is then possible to have different times and dates in a sysplex? I always assumed there is a single clock and a single time in a sysplex, and all sysplex-wide applications use this concept: all logs, data sharing, couple data sets...

Neither system nor applications know that these volumes are no more accessible. There are no messages in syslog / operlog / application logs about any problems concerning the allocated volumes.

Re: Allocated volumes after the power loss in the storage subsyst em
Kees, thank you for the reply. I wonder if the I/O does not time out and recovery procedures will be driven. In that case the timeouts must be extremly long (more than a couple of hours) g. You could try the V ,OFFLINE,FORCE to Box devices. This will terminate all outstanding I/O's with an I/O error and this should trigger some action in the applications.

By the time we tried to fix the problems in DB2, we found that the status of alloc for those devices somehow misleading. Anyway, we did not found a solution how to free the applications out of this.

Re: how to lose a sysplex in 30 seconds

Re: how to lose a sysplex in 30 seconds
Bill, - snip - The existence of signalling connectivity created a race condition, in which MVSA and MVSB were competing to detect and report the loss of access to the CDS at their respective sites. MVSB won the race, detecting and signalling the loss of the primary CDS before MVSA detected loss of the alternate. MVSA got MVSB's signal, initiated removal of the primary, and then detected the inaccessibility of the alternate. - snip - What would happen if MVSA got the race? Would MVSB try to access the primary during acknowledgment of the removal of the alternate CDS? If not, could it survive the loss of connectivity to primary if it (connectivity loss) would be short enough?

Re: Geoplex performance considerations
It depends on what you call CF mirroring: System Managed Coupling Facility Structure Duplexing is supported now. This requires direct links between the CF's and these links seem to be limited to 5 km to prevent unacceptable delays. According to System-Managed CF Structure Duplexing, page 32 GM13-0103-05 (June 2004) URL: http://www-03.ibm.com/servers/eserver/zseries/library/techpapers/pdf/gm13010 3.pdf Recommendation: In a GDPS/PPRC multi-site configuration, do not duplex CF structure data between coupling facilities located in different sites; rather, if desired, duplex the structures between two coupling facilities located at the same site. CF structure data is not preserved in GDPS site failover situations, regardless of CF Duplexing.

Re: ESS pprc question
We have two ESS800 in two locations with PPRC v2. We plan to power-off ESS_A (primary) for realocation (1-2 hours). For this period of time system and application will be stopped.
