If you defined a profile data set with a fixed record length DCB attribute, for example, of 80, and issued a NTD command to import a previously exported profile you would see the following message in your RKLVLOG output: KC2IMP - Member &dsn(&mbn) is not a valid profile KC2IMPFF - Import failed for profile xxxx KC2IMP - KLVTBULD failed with rc=6 reason=1 When you are upgrading OMEGAMON II for CICS profiles from V4.1.0 to V4.2.0 use the dynamic profile export/import facility interface to import your profiles. Before you begin your... [More]

Many systems programmers spend hours debugging problems that involve looping or hung transactions. By working together, z/OS and CICS systems programmers resolve these problems much faster by combining the information available from OMEGAMON XE on z/OS and OMEGAMON XE for CICS on z/OS.
A typical scenario is that the z/OS systems programmer identifies an address space with a high (or low) CPU Percent. Most often, this is in response to a situation alert or a reported problem. Starting with the Address Space Overview workspace in OMEGAMON... [More]
A few years ago I wrote a lengthy article about how the CICS TG monitoring agent delivered as part of the OMEGAMON XE for CICS product opens up the black-box of CICS Transaction Gateway (CICS TG) on z/OS giving system administrators the information required to tune their CICS TG resources in order to optimize throughput and minimize bottlenecks within this key middleware component. Well, as time moves on URLs change and the original article seems to have disappeared into the ether. The details within in it however, are still very much valid and... [More]

Self-Describing Agent feature that reduces the cost of deployment and
maintenance for... [More]
No, this not a new sitcom announcement about a new show that you can see once a week. It's rather about a tool that you can use everyday to diagnose a check in your CICS Transaction Server for z/OS. You think the abend is caused by a wild branch. You need to know, what is the BEAR, and how can you use it to resolve the abend? CICS TS V3.1, and later, now provides the contents of the Breaking Event Address Register (BEAR). The BEAR is a hardware enhancement in z9-109 (z/Architecture mode). The BEAR is a 64-bit register that contains the... [More]
You want to upgrade to z/OS V1.13, but you do not know if your release of CICS Transaction Server for z/OS (CICS TS) or the CICS Tool(s) you are using are compatible with z/OS V1.13?
Your trepidation might be because the z/OS V1.13 General Availability (GA) was after the GA of some of the
releases of the CICS products you are using. No worries! IBM has successfully tested CICS TS V3.1, V3.2, V4.1, and V4.2 with z/OS V1.13. For a list of CICS Tools that were successfully tested with z/OS V1.13, see this Technote See the... [More]
You are starting a new CICS Transaction Server region under a new release of CICS. You receive message DFHKE0104 to indicate an incorrect SVC number has been supplied to CICS. This message is followed by messages DFHPA1909 and DFHPA1910, indicating SVC number and CICSSVC DFHSIT override are not correct. DFHKE0104: CICS has been supplied with incorrect SVC number. DFHPA1909: Data is invalid for keyword. Respecify keyword and data. DFHPA1910: SIT override is not recognized. Override is ignored. The probable cause of this issue is the CICS... [More]
A customer recently needed to review an earlier transaction they had created and found that the ONDV data had been wrapped-around. The customer saved their history data in a VSAM file and they needed to increase the size of their historical data. This history file reallocation can be can be changed dynamically through the Configuration Tool. From PRODUCT COMPONENT SELECTION MENU, select OMEGAMON II for CICS. The CONFIGURE OMEGAMON II FOR CICS / RTE: xxxx panel is displayed. On the CONFIGURE OMEGAMON II FOR CICS / RTE: xxxx panel, select 5,... [More]
When you are making global entry changes (KC2GLBxx) and you want these changes to be picked up, a simple OMEG RECYCLE will suffice. You do not have to recycle your CICS region or recyle the classic started task or even perform a OMEG SHUT, OMEG REMOVE or OMEG INIT for that matter. The only time you need to do anything other than a OMEG RECYCLE is if the name of your GLOBAL (KC2GLBxx) has changed. Then you need to update the DD card in the CICS region. In this case, however, you do need to recycle the CICS region. Note: It is very important... [More]

Over the years there have been some inquisitive CICS customers that have wanted to know more about Temporary Storage Queues (TSQ) and Transient Data Queues (TDQ) data in the world of CICS. After doing some research and chatting with a CICS developer here are some differences between TSQ's and TDQ's. In TSQ, data can be written and read either sequentially or randomly, while in TDQ, the data is written or read only sequentially. TSQ's can be both input and output, while TDQ's are either input or output. In TSQ, the data can be read any number... [More]
As a software and information developer, interacting with your support team on a regular basis is a viable way to head off customer problems early on and provide real time solutions that signifies team work. The support level personnel within a company is designed to incorporate a solid working knowledge of the software product they support coupled with an innate skill base that fosters problem solving and the handling of complex customer issues in a timely manner. It's important, however, to let customers know how they can save time and... [More]
