IOF Support for

JES2 Encryption/Compression

Encryption and Compression Support
New JF (job find) command
RUNIOF command
Support for JES2 V2R4


IOF Maintenance  (for Release 8G only) is now available to provide support for JES2 encryption and compression.   The latest spin level has this maintenance applied, or you can alternately download and apply the latest  CUMFIX file. However, the RUNIOF command described below is only available with the MPI install.

IOF continues to support previous versions of z/OS with the encryption and compression  maintenance applied.

JES2 Dataset Encryption and Compression Support

 It has maintenance applied to support JES2 data set encryption and compression.  IOF properly displays encrypted data sets to authorized users, and decompresses compressed data sets. To get this support you must either install the latest MPI file, or download and apply all fixes in the latest  8G CUMFIX file.

JF  (Job Find) Command

The JF (Job Find) command was made available at spin level 2019256.  If you did not install that spin level or a recent CUMFIX file then the new JF command will become available  with this latest MPI (or CUMFIX file).

The JF command works very much like the popular ZF command, except that it scans a list of jobs from the IOF Job List Menu instead of a PDS.   From the list of "hits" you can drill down to a specific sysout in a specific job.  Like ZF, you can use any valid ISPF FIND parms:

JF blarg 10 All sysout and sysin data sets
JFI blarg  word Only INPUTJCL and sysin data sets
JFM blarg 5 20 Only Log, JCL and Messages data sets
JFD sysprint blarg Only sysouts with DDNAME of SYSPRINT
JFS 9999 blarg Only sysouts with less than 9999 record

To reduce your search time, before entering your JF command you can limit Job List by using EXCLUDE commands.  For example,
EXCLUDE JOBNAME NB ABCD (only jobs named ABCD* )
EXCLUDE JOBNAME NC BCD (only job names containing BCD)

Enter the JF command with no parms on any IOF screen to see more information about the JFx commands.

RUNIOF Command

The RUNIOF command is available only if you installed IOF by executing the MPI file.  There is no fix in the CUMFIX file that adds this command.

RUNIOF lets you invoke alternate versions of  IOF, which can be particularily useful for testing new generations of the product: 

RUNIOF  8G1  - to run version 8G1

z/OS Version 2.4 Support

IOF Release 8G with fixes U8G2748 and U8G2750 applied provides support for all releases of z/OS through version 2 release 4.  Release 8G is the only IOF release that runs with z/OS V2R4.


The latest release of IOF is Release 8G. The latest spin level of  IOF Release 8G is 2021278 (October 5, 2021).


 The cumulative fix file (CUMFIX) was also uploaded at the same time.
