Tape Encryption- Design Direction
Tape control unit TS1120 and tape drive TS1120 E05-EE support writing
encrypted data to tape
Data is encrypted in control unit
IBM Java Encryption Key Manager component must run on another
operating system such as: z/OS; Linux; AIX; other UNIX; or Windows.
Communication to control unit using TCP/IP
Key negotiated when writing to tape
Control unit obtains key when reading tape
TPF design direction
Ability to specify that a tape must be written as encrypted
Tape label attribute - ZTLBL
Tape mount - ZTMNT
Ability to enable a tape drive for automatic tape mounting using
encryption - ZTDEV ENABLE

Protect Data in Use - Design Direction
When an ECB is using sensitive data, it is in the clear in memory
Data can show in dumps
Data can be displayed using ZDCOR
Data can be displayed through debugging tools
Requirement
Specify that an area of memory will not show actual data in a dump
or in a ZDCOR display
Format secure data as a series of ********
Areas of memory include:
ECB Heap
ECB private area

Protect Data in Use - Design Direction
API to mark area of memory as not displayable
Give starting address and length
Address must be in
ECB Heap
ECB Private area
No other core addresses will be supported
Address must be in use otherwise SERRC E
If free is done and the address is marked, the marked area will be zeroed.
If RELCC is done on marked core block, the marked area will be zeroed.
API to unmark area of memory so that it can be displayed
Give starting address and length
Range does not need to match previously marked area
Will not zero memory
All areas of ECB memory are considered displayable when allocated
API to query areas of memory that are marked as not displayable
Intend for other ECBs (ZDCOR) to know what to not display
Dump processing to use to know what to not format

Time Slice Changes - Design Direction
Requirement: allow time slicing to be enabled for the life of the ECB
Eliminate restriction where time slicing cannot be enabled across TPF system
services
Enter
SVC
TPFDF call
Provide ability to specify whether an ECB can be sliced in a program
New column in control file
PAT option
Sample command to be provided which will add the new column to
existing control files
Default setting by command will be to allow time slice in the program
Recommend programs be defined as not sliceable if they do LOCKC
Programs should not give up control if they are holding a LOCKC lock
Allow nesting of time slice calls

z/TPF Tools Consideration
Treat tools as part of the product code
For example, time slice changes expect to add column to control file
Changes will be needed to build tools
bldtpf
maketpf
pat2ctl
Tool updates will be part of the APAR
Updates to maketpf will NOT be downwardly compatible with control files that
do not have the new column for the time slice option
Apply updates the tpftools/ source files like all other z/TPF source files
tpftools/ directory must be under the same root as other z/TPF source directories
For example, a PUT 02 directory structure may look like..
PUT02/base
..most z/TPF source for PUT 02
PUT02/tpftools
..z/TPF tools
And a PUT 03 directory structure may look like..
PUT03/base
..most z/TPF source for PUT 03
PUT03/tpftools
..z/TPF tools

CPU Check Load - Design Direction
Workload License Charging provides ability to charged based on
processors usage rather than processor size.
Monthly charge based on the highest 4 hour rolling average during
the month
Feedback: do NOT want utilities to drive monthly charge
Want transactions to drive monthly charge
Requirement: provide means to throttle utilities so that they do not drive
monthly charge

CPU Check Load - Design Direction
Provide API to control ECBs based on processesor utilization
LODIC extension
Utilization classes added to LODIC
Separate from existing resource classes
Utilization class will have a shutdown utilization
Unique shutdown per logical processor
If processor utilization is higher than shutdown,
ECB can be suspended until processor utilization is less than shutdown
ECB added to new extension of the suspend list
Return can be given to ECB stating that processor utilization is too high
Intended for processes which are not executed if processor utilization
is too high
Utilization classes are defined and modified using the ZSYSL command
Utilization classes definitions are kept in file system and not CTKA

CPU Check Load - Design Direction
Provide ability to exclude utilization of specific utilities in utilization class
Utilities are identified by ECB owner name
Means to prioritize different utilization classes
Example remove Recoup from a utilization class
Shutdown utilization for class MYCLASS = 75%
Processor utilization = 95%
Recoup utilization = 25%
Utilization 95 - 25 = 70% is compared to MYCLASS shutdown
70% < 75% MYCLASS is not in shutdown
Owner names can be exclude from a utilization class using the ZSYSL
command
Multiple owner names can be excluded from a single utilization class
Processor utilization calculated every 50 milliseconds
Each I-Stream calculates its own utilization
Utilization for all I-Streams are averaged to get processor utilization
Utilization of ECB owner names is determined used sampling

Recoup Deferred Lost - Design Direction
Issue: analysis of Recoup lost addresses can take a long time
Cannot run PDU until Recoup is rolled in (ZRECP PROCEED)
Need large buffer of pool addresses to cover time to do Recoup
Change: Recoup roll in to be two steps
ZRECP PROCEED will return pre (Recoup) and during (Recoup) RFS
Roll in of lost addresses will be a separate step
New PDU option
Lost address handling
No changes in ADR tape processing
New pseudo directory (#SONLOST) to contain lost addresses
Online database of lost addresses kept in fixed file records
Ability to exclude lost addresses by record ID / pool section
Additional changes
File system file will contain lost address record ID counts
ID counts for each long term pool section
