Re: Creating new SMS environment in a monoplex
I can confirm that. We have 2 sysplexes (Prod and Test), both with 2 GPDS K-systems. GDPS K-systems don's share Dasd with the other systems of the sysplex. So we have 6 SMS environments, each with their own SCDS, ACDS and COMMDS. We have 1 SMS configuration that covers all systems and in the ACS routines, we route datasets to storage groups, depending on the system it runs on. We update the 'source' SMS configuration on the test sysplex systems, activate it on the 3 SMS environments in the Test Sysplex and test it. Then we transfer the SCDS to the 3 SMS environments of the Prod Sysplex and activate it there. We have no problem with this setup. The advantage is that you don't make typo's when trying to copy the updates in the test-environment to the prod-environment.

Re: tcpip or telnet
Generic response time monitoring for TCP is not possible. You need to set expectations based on the monitors you decide to use. To understand the problem, think about what is considered a delay. TN3270 delays are clearly defined (press enter to screen returned). The Unix equivalent is telnet which takes a different approach. Every user keystroke is sent to the host application and does not expect a response. At some point, the application will decide to send a response for reasons only known to the application. Telnet does not have 2 points in time to be measured. Your best resource for information and help will probably be your TCP network people. They understand your environment and may have tools that meet your needs. They may be better positioned to do some of the monitoring because they are aware of TCP environmental changes. Worst case, they can help set expectations.

Re: Creating new SMS environment in a monoplex
Skip, I think the point my boss was trying to make is that there is residual information stored in the Parallel Sysplexed ACDS that makes a SAVEACDS copy of it unusable for use on a monoplex. I begged to differ and posted here to see what others thought. I added the new lpar's system name into the base configuration and activated it prior to issuing the SAVEACDS. When I perform an IPL of the new system, I expect it to recognize that system name and a D SMS to show it active while all the other system names will show hyphens and N/A under Interval Seconds.

Re: Creating new SMS environment in a monoplex
W dniu 18.05.2020 o 20:36, Richards, Robert B. pisze: It has been a few decades since I have created a new SMS environment. Current environment is parallel sysplex replete with CFs and lots of lpars. I am trying to create a simple SMS environment that will be part of a monoplex consisting on one lpar. I did the following: 1. Defined the new SYSNAME into the base configuration in ISMF and activated same. D SMS verified it was defined and not active 2. A REPRO of the SCDS into a new SCDS dataset (Alter/newname to correct usercat) 3. Issued a SETSMS SAVEACDS(also using a SSA connector that I subsequently ALTER NEWNAME the new ACDS into a new usercat that is connected to a new mastercat) 4. Defined an empty COMMDS that I also performed an alter/newname to get the desired COMMDS dataset name. My boss says the ACDS is aware of the original sysplex environment and my gyrations of trying to make the above work in a monoplex will not succeed. Who is right? Will it work or not? Quick and dirty method: 1. Add new system name to existing SCDS and ACDS. Don't worry, it is nothing wrong to have non-present system names there. 2. Copy all *CDS to disk belonging to new system. 3. IPL the system. Of course this is method for some migration. ACS routines, class definitions and library definitions will be moved. Is that what you want? Otherwise there is another method, to start from scratch. ACS routines can be easily imported, class definitions - the only way I know is to re-define them manually. BTW: some dummy SMS environment is delivered with ServerPac. I always start from that point. Then IPL with CPAC system name, then add my name to ACDS then reIPL with my system name. Then *CDS datasets can be imported (copied).

Re: Does allocating an HFS or zFS erase all existing data?intervals formatted?
There is, or used to be, a common service used by VSAM and other components for data with CI-like formatting, including PDSE. If it still exists then I assume that it is also used for HFS. My prime concern was HFS and zFS, and I don't know whether SPEED/RECOVERY applies to linear, which zFS is based on. -- Shmuel (Seymour J.) Metz http://mason.gmu.edu/~smetz3 From: IBM Mainframe Discussion List [IBM-MAIN@LISTSERV.UA.EDU] on behalf of Mike Kerford-Byrnes [m...@hill-leys.com] Sent: Tuesday, May 19, 2020 8:11 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Does allocating an HFS or zFS erase all existing data?intervals formatted? >From various manuals - and a lot of time spent with VSAM... A VSAM file is DEFINEd with an amount of space. This space is managed by VSAM as a set of Control Areas (CAs). The maximum size of a CA is 1 Cylinder, and the minimum is one track. Each CA contains a number of Control Intervals (CIs), of fixed length, determined at DEFINE time. The last 4 bytes of a CI (the CIDF) contain information as to the occupancy of the CI (amount of unused space and its offset). A CIDF containing all zeros is known as a Software End Of File or SEOF. The CIDF of an EMPTY CI shows (CISIZ - 4) bytes available at offset 0. Records are stored in the CI (left to right) along with control information (3-byte 'RDF' stored right to left). Linear Datasets are different. They do not have any control information in the (mandatory) 4K CIs which are employed to store the data. As far as I can deduce, the only connection to VSAM is that it provides the vehicle to read and write 4K blocks of data to and from a disk and a catalog structure in which to hold relevant data about the file - name, size, volser etc. Although I have used a linear Dataset in the past (1994!) I have not researched it in any detail. When a file is DEFINEd, nothing happens to the tracks. Only when the file is loaded does anything happen. What happens depends on the choice of SPEED/RECOVERY at DEFINE time and the type of VSAM file. SPEED When SPEED is specified, records are loaded into each control interval, along with the RDF, and the CIDF is updated as each record is loaded. This continues across all relevant CIs until the load is complete. At CLOSE (and only then), the SEOF is written and the Catalog will show a value in the High Used RBA field. For ESDS and RRDS, the SEOF is written in the CI FOLLOWING the last occupied CI. All remaining CIs in the current CA are also formatted as EMPTY. For a KSDS, all remaining CIs in the CA are formatted as EMPTY, and the first CI in the NEXT CA is also formatted as SEOF (assuming space is available). The HURBA reflects the last byte in the CA that contains loaded data. RECOVERY When RECOVERY is specified (or defaulted), each CA is preformatted immediately prior to its load. For both ESDS and RRDS, each CI in the CA is formatted with SEOF. For a KSDS, All CIs in the CA are formatted as EMPTY and the first CI of the NEXT CA is also formatted as a SEOF (again assuming space is available). In all cases, the load of that CA proceeds updating each CI in turn. CLOSE will update the HURBA as per SPEED. The net of this is that, in the case of RECOVERY, if the load fails part-way through, there is a predictable format in the file structure such that a 'resume load' can be executed (that is if you have programmed one to start with!). There will always be a SEOF which identifies the last point at which data was loaded. This is identified when a subsequent OPEN, having detected a 'failed CLOSE', invokes the VERIFY function, which locates the SEOF, updates the catalog and then resumes the OPEN process with a 'clean' catalog. In the case of SPEED, there is no such support and you have to go back to the beginning and rerun. Although RECOVERY is the default, IBM recommend SPEED, since it is obviously a faster option. There is one 'gotcha' in this story. Once a file has been loaded (I.e. at least one record written, followed by a successful CLOSE), RECOVERY is operative, irrespective of the SPEED/RECOVERY option chosen at DEFINE time. So don't do what I have seen a couple of times - Open, load 1 control record, Close, followed by Open, load thousands of records, Close - under the misconception that SPEED is in effect throughout.

Hi In a linux environment you could use tools like ping and traceroute. You would see, if your target is reachable and how fast the connection is (latency between nodes). The availability (and names) of such (basic) tools depend on your operating system. e.g. some z/OS info: https://www.ibm.com/support/knowledgecenter/zosbasics/com.ibm.zos.znetwork/znetwork_344.htm Using PING and REXX you could easily write such a reporting tool that scans your target IP addresses.

Re: Does allocating an HFS or zFS erase all existing data?intervals formatted?
>From various manuals - and a lot of time spent with VSAM... A VSAM file is DEFINEd with an amount of space. This space is managed by VSAM as a set of Control Areas (CAs). The maximum size of a CA is 1 Cylinder, and the minimum is one track. Each CA contains a number of Control Intervals (CIs), of fixed length, determined at DEFINE time. The last 4 bytes of a CI (the CIDF) contain information as to the occupancy of the CI (amount of unused space and its offset). A CIDF containing all zeros is known as a Software End Of File or SEOF. The CIDF of an EMPTY CI shows (CISIZ - 4) bytes available at offset 0. Records are stored in the CI (left to right) along with control information (3-byte 'RDF' stored right to left). Linear Datasets are different. They do not have any control information in the (mandatory) 4K CIs which are employed to store the data. As far as I can deduce, the only connection to VSAM is that it provides the vehicle to read and write 4K blocks of data to and from a disk and a catalog structure in which to hold relevant data about the file - name, size, volser etc. Although I have used a linear Dataset in the past (1994!) I have not researched it in any detail. When a file is DEFINEd, nothing happens to the tracks. Only when the file is loaded does anything happen. What happens depends on the choice of SPEED/RECOVERY at DEFINE time and the type of VSAM file. SPEED When SPEED is specified, records are loaded into each control interval, along with the RDF, and the CIDF is updated as each record is loaded. This continues across all relevant CIs until the load is complete. At CLOSE (and only then), the SEOF is written and the Catalog will show a value in the High Used RBA field. For ESDS and RRDS, the SEOF is written in the CI FOLLOWING the last occupied CI. All remaining CIs in the current CA are also formatted as EMPTY. For a KSDS, all remaining CIs in the CA are formatted as EMPTY, and the first CI in the NEXT CA is also formatted as SEOF (assuming space is available). The HURBA reflects the last byte in the CA that contains loaded data. RECOVERY When RECOVERY is specified (or defaulted), each CA is preformatted immediately prior to its load. For both ESDS and RRDS, each CI in the CA is formatted with SEOF. For a KSDS, All CIs in the CA are formatted as EMPTY and the first CI of the NEXT CA is also formatted as a SEOF (again assuming space is available). In all cases, the load of that CA proceeds updating each CI in turn. CLOSE will update the HURBA as per SPEED. The net of this is that, in the case of RECOVERY, if the load fails part-way through, there is a predictable format in the file structure such that a 'resume load' can be executed (that is if you have programmed one to start with!). There will always be a SEOF which identifies the last point at which data was loaded. This is identified when a subsequent OPEN, having detected a 'failed CLOSE', invokes the VERIFY function, which locates the SEOF, updates the catalog and then resumes the OPEN process with a 'clean' catalog. In the case of SPEED, there is no such support and you have to go back to the beginning and rerun. Although RECOVERY is the default, IBM recommend SPEED, since it is obviously a faster option. There is one 'gotcha' in this story. Once a file has been loaded (I.e. at least one record written, followed by a successful CLOSE), RECOVERY is operative, irrespective of the SPEED/RECOVERY option chosen at DEFINE time. So don't do what I have seen a couple of times - Open, load 1 control record, Close, followed by Open, load thousands of records, Close - under the misconception that SPEED is in effect throughout.
