CPU accounting information reported as 0 in IIB, due to limitation in clock() function.

We run IBM Integration Bus on z/OS and use the accounting feature of the product. We use it for distributing the costs internally based on the usage for different message flows.The message flow that consumes the most CPU is reported as 0 CPU consu...

The clock() function that determines process time on z/OS needs to be increased or reset to zero after it reaches max value

We have a PMR 29022,082,000 opened with IBM Integration Bus V10 support about SMF CPU time not reporting correctly for some message flows. L3 found that the clock () function they were using to calculate processor time hit max value so they could ...

Option to report silent exception handling in LE

During some performance analysis we discovered in CICS trace a huge amount of S0CA - decimal overflow - interrupts caught and recovered by Language Environment. These were caused by a simple ADD statement in a cobol program which runs in an ILC en...

Allow z/OS C/C++ library to write zero-length data set records using record mode processing.

The z/OS C/C++ library will currently not allow the creation of zero-length records using record-mode processing using fwrite(). This applies to RECFM=V*, and RECFM=U. It is possible using text mode, but this does not allow for binary processing. ...

Support record-wrapping in the z/OS C/C++ library

There is currently no option in the C/C++ library to wrap when writing data set records in "text" mode. The library *does* do this automatically for spool file data sets, but a line written to a regular data set that is longer than the maximum len...
