4 Agenda Tape Encryption Protect Data in Use Time Slice Changes z/tpf Tools Consideration CPU Check Load Recoup Deferred Lost TPFUG October 2006 Main CP Team.PRZ 10/30/06 Pages 4

5 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 TPFUG October 2006 Main CP Team.PRZ 10/30/06 Pages 5

6 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 TPFUG October 2006 Main CP Team.PRZ 10/30/06 Pages 6

7 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 TPFUG October 2006 Main CP Team.PRZ 10/30/06 Pages 7

8 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 TPFUG October 2006 Main CP Team.PRZ 10/30/06 Pages 8

9 Time Slice Changes - Example #1 Program A TMSLC ENABLE ENTRC Program B Program B (a) Program B defined as not sliceable BACKC (b) Interrupt taken to slice the ECB in Program B TMSLC DISABLE EXITC (c) ECB is NOT time sliced (d) Give up control on return to Program A TPFUG October 2006 Main CP Team.PRZ 10/30/06 Pages 9

10 Time Slice Changes - Example #2 Program A TMSLC ENABLE ENTRC Program B Program B (a) Program B defined as sliceable TMSLC DISABLE EXITC BACKC (b) Interrupt taken to slice the ECB in Program B (c) ECB gives up control TPFUG October 2006 Main CP Team.PRZ 10/30/06 Pages 10

11 Time Slice Changes - Example #3 Program A TMSLC ENABLE ENTRC Program B Program B TMSLC ENABLE Nesting to be supported TMSLC DISABLE BACKC TMSLC DISABLE EXITC TPFUG October 2006 Main CP Team.PRZ 10/30/06 Pages 11

12 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 TPFUG October 2006 Main CP Team.PRZ 10/30/06 Pages 12

13 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 TPFUG October 2006 Main CP Team.PRZ 10/30/06 Pages 13

14 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 TPFUG October 2006 Main CP Team.PRZ 10/30/06 Pages 14

15 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 = 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 TPFUG October 2006 Main CP Team.PRZ 10/30/06 Pages 15

16 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 TPFUG October 2006 Main CP Team.PRZ 10/30/06 Pages 16

17 Recoup Steps - Design Direction Step Today Deferred Lost 1 Start Recoup ZRECP START Start Recoup ZRECP START 2 Start Phase 1 ZRECP RECALL Start Phase 1 ZRECP RECALL 3 Resume after Phase 2 ends ZRECP RESUME Resume after Phase 2 ends ZRECP RESUME 4 Protect erroneously available addresses ZRECP PROTECT Protect erroneously available addresses Done automatically 5 Lost address handling ZRECP REBUILD / NOREBUILD Lost address handling Deferred until after rollin 6 Roll in ZRECP PROCEED Roll in pre and during pool releases ZRECP PROCEED 7 Standard PDUs can be run Standard PDUs can be run 8 Create lost address database 9 Lost address handling 10 Roll in lost addresses via PDU TPFUG October 2006 Main CP Team.PRZ 10/30/06 Pages 17
