To maintain compatibility we try to avoid breaking changes to the API, however there will be occasions where they are necessary. In most cases this will be caused by methods that return invalid data or have the wrong data type, so they are unlikely to be in general use.
To reduce the chance of being affected by breaking changes, if you find a field where the data type seems incorrect please open a support request to correct it rather than code around it. E.g. Dates and times that are LocalTime not ZonedDateTime (GMT).
Any breaking changes will be listed in the release notes.
Current: Version 1.6.1 – XMI Format – Zip Format
Changes
- Fix sample scripts for Windows and Unix to work with modified installation directory structure
- Change Unix script to use Unix line endings instead of DOS/Windoes line endings
Current: Version 1.6.0 – XMI Format – Zip Format
Changes
- Improve the installation process. Installation now takes place into a directory structure under ./easysmf-v-r-m/ to make it easier to install multiple version side by side.
- Add record type 16
- Add function to open a SMF file or dataset by name, not just using a preallocated DDNAME or from a stream.
- SMF record updates
Version 1.5.1 – XMI Format – Zip Format
Changes
- Always reassemble records if required, not just when reading from RECFM=U blocks. In some circumstances it seems that data is deblocked but spanned records are not reassembled.
- Improve messages and diagnostic information for some common errors.
Version 1.5.0 – XMI Format – Zip Format
Changes
- Add methods to type 30 records to return a single section or null for sections where it is documented that there will be zero or one instances. The older methods that returned a list containing zero or 1 entries still exist and are still fully supported.
- More extensive use of JZOS data conversion for possible performance improvements running on z/OS.
- SMF Record Updates
Version 1.4.0 – XMI Format – Zip Format
Changes
- Update DB2 mapping for DB2 V12
- Add SMF record types 14, 15, 61, 62, 64, 65, 66, 88.
- Add support for reading from SMF data files downloaded using RECFM=U i.e. they include the Block Descriptor Word and spanned records need to be reassembled.
- Times reported as durations (e.g. CPU time) are also available as a double (floating point) value in seconds, for easier calculations and possibly better performance.
- Updates to SMF records.
Version 1.3.1 – XMI Format – Zip Format
Changes
- Add a SmfRecordWriter class so that the API can be used for record filtering, sorting etc.
- Some invalid license keys were created in error. This version has changes to tolerate those keys.
Version 1.3.0 – XMI Format – Zip Format
Breaking Changes
- SMF section constructors, which were documented as being for internal use only, are now marked private.
- Experimental DB2 support: Create a class to represent DB2 Accounting Token QWHCTOKN instead of using a BigInteger.
The token contains mixed text and binary data. Using a separate class allows toString() etc. to be tailored to be more appropriate for the content and should avoid other breaking changes for this field in the future.
Other Changes
Usability Improvements:
- Add support for DD statement pointing to key location
- Modify sample JCL procedures to allow user specified environment changes in a single step instead of using a preceding setup step.
- Messages from EasySMF are now issued using the SLF4J logging framework instead of writing to STDOUT.
This means that EasySMF messages are not mixed with program output written to STDOUT.
SLF4J allows the message destination to be tailored if required. The default destination as shipped is STDERR.
Version 1.2.1 – XMI Format – Zip Format
Breaking Changes
- Some methods tested fields for values which were actually masks to define the bits used. The returned values were meaningless so the methods have been removed:
- smf70poi()
- smf73rv3()
- r744hsav()
- r745sos()
- r745sdcs()
- r745sdfw()
- r745sdps()
- r745sod()
- r745scol()
- r745svst()
- r745spda()
- r745dfrm()
- r745dsdv()
- r745dsfw()
- r745dsdp()
- r745dsod()
- r745dcol()
- r745dvst()
- r745dpdt()
- smf89lp1()
- smf89lp2()
- Some methods which returned binary data as a string, which is unlikely to be useful/correct, have been removed:
- r783hdat()
- r783cc()
- r783cd()
Other Changes
- Add classes to map SMF type 121 records
- Updates to existing SMF records to reflect IBM Changes
- Modify samples to demonstrate usage of Java 8 Streams
- Add sample report for type 41 VLF report
- Correct handling of some equate values
Version 1.2.0 – XMI Format – Zip format
- Add classes to map DB2 type 100 and 101 records
- Add classes to map SMF type 42 records
- Add classes to map SMF type 89 records
- Updates to existing SMF records to reflect IBM Changes
