IBM recently announced the open beta of CICS Transaction Gateway on z/OS V9.1 . There are a number of significant new features provided, most notably JSON web service support allowing mobile clients to connect directly into a Gateway daemon and route requests securely through to CICS with minimal fuss.
You can read more about the new features here and watch a brief video below of the mobile enhancement.

If you've been following the updates of the IBM Tivoli Monitoring and OMEGAMON product family over the past year you can't have failed to notice one of the key features being promoted is “Self-Describing Agents” or SDA. Perhaps you have moved to the latest releases and have started using this enhancement (if you have, keep reading, there may be some subtle information here you may not be already aware of), or you may be in the process of planning your upgrade and have not yet considered what benefits the SDA feature will...

Re: OMEGAMON Beta Program
The OMEGAMON Development team is looking for interested customers and business partners to participate in the Beta Program for the next release of the IBM OMEGAMON family. The Beta Program started on January 13, 2014 with OMEGAMON XE for CICS on z/OS, and on February 17, 2014 OMEGAMON XE for Messaging on z/OS was added. OMEGAMON XE on z/OS beta code will be available soon for download and installation.
When you associate a mouse click with the Enter key in your 3270 emulator session (see the June 21 2013 blog on how to do this)
then with the Enhanced 3270UI you can go ZOOM ZOOM ZOOM from high level issue very quickly to the specific details.
Here is an example using the OMEGAMON Performance Management Suite and the OMEGAMON XE for Storage feature
where we start at the SMSPLEX overview and see the highest DASD Volume response is 23.2 ms
Are your DB2 threads getting enough resources? Are the Work Load Manager Enclave (WLM) definitions too restrictive?
If on the Enhanced 3270UI using the DB2 ® active threads summary (select 'T' from the Enterprise Summary) or the DB2 Thread Detail Accounting screen you see that the elapsed time for a distributed thread is greater than the threshold you have set (the plan name DISTSERV and the correlation ID starting with db2jcc_ indicates this is a distributed thread),
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]
IBM has announced the new IBM Tivoli OMEGAMON Performance Management Suite for z/OS V5.1.1.

You've been storing data collected by OMEGAMON XE on z/OS in the Tivoli Data Warehouse. You can identify problems that occured in the past using the Tivoli Enterprise Portal. You can go learn more and keep your z/OS systems running smoothly by regularly running the following reports on detailed and summarized data:
z/OS Status DASD Issues
z/OS Status WLM Service Class Period
z/OS Utilization Common Storage
z/OS Utilization LPAR Summary
z/OS Utilization LPAR Usage Summary
Deadlocks and timeouts are unresolved contentions in DB2. These unresolved contentions might cause incomplete transactions and might degrade the overall performance of your system. It is important to monitor and resolve these contentions. Tivoli OMEGAMON XE for DB2 Performance Expert on z/OS (OMPE) is invaluable in detecting and analyzing DB2 for z/OS deadlocks and timeouts. The following link takes you to some of IBM's recommended best practices using OMPE to identify where these are occurring then what steps to take to resolve the... [More]
Welcome to the new age of CS&I OMEGAMON Beta programs! We have an exciting new program to offer you...
As part of our use of agile development, each beta driver that we make available with the OMEGAMON Performance Management Suite beta will be a near GA-ready solution. This is quite different from the beta programs you have experienced in the past. You might recall that in the "old age" of beta programs, prior to agile development, you would get a beta driver of very early GA development code and... [More]
Popular PARMGEN FAQs about base-sharing RTEs:
FAQ#1: How do I create a brand new base-sharing RTE (RTE Name=SHRBASEP) in PARMGEN mode?
FAQ#2. How do I convert an ICAT Base RTE (RTE Name=BASE1) and an ICAT base-sharing RTE (RTE Name=SHRBASEI) in PARMGEN?
PARMGEN streamlined the set-up and deployment of sharing RTEs in general. Creating the shared-to RTE (a Base RTE in this case)
and the RTE that shares the Base is a one-step process in PARMGEN mode .
