Migration (2/2) Library changes (Linklist / LPALST / APF updates) APK.ACIF.SAPKMOD1 renamed to APK.SAPKMOD1 (PSF ACIF feature) ICA.SICALOAD deleted (ISS Firewall removed) ISP.SISPSASC deleted (ISPF) Library changes (USS) Root HFS splitted into more separate product datasets SMF changes Type 26 (JES2), Type 80 (RACF) Type 30, 32, 33 (EXCP count) Chart-Nr. 4 SMF changes: rolled back to z/os 1.7 with UA24585 4

Neue Funktionen (1 / 5) LE Runtime Options Force IPCS readable dump DYNDUMP(*userid,NODYNAMIC,TDUMP) ISPF UNIX directory list (Opt. 3.17) File tailoring enhancements )REXX, )ENDREXX &STR, &STRIP, &SUBSTR, VGET system symbolic variables Primary command FILTER on member lists RENAME ALIAS support Chart-Nr. 5 LE Runtime Options For U40xx abends (other than U4039), regardless of wether a SYSUDUMP, SYSABEND or SYSMDUMP dataset is allocated, a dump is written to the HLQ specified in the option. ISPF ISPF Opt. 3.17 USS directory list utility to browse, edit, delete, rename, copy, modify attributes, execute UNIX files File tailoring enhancements: )REXX, )ENDREXX, add. Functions like &STR, &STRIP, &SUBSTR, VGET system symbolic variables FILTER: allows to subset using all member attributes (Create, Alias, Size, ). FILTER can be used repeatedly to reduce the number of members displayed. RENAME ALIAS support: the rename command will also update all of the member s aliases to point to the new name 5

Neue Funktionen (2 / 5) DFSMS LISTC performance SETSMS COPYSCDS DISPLAY SMS,SMSVSAM,DIAG(CONTENTION) USS Send messages to the sysplex message log (/dev/operlog) /etc/inittab support F OMVS,STOPPFS=ZFS NFS Chart-Nr. 6 DFSMS LISTC performance: e.g. elapsed time for LISTC ALL CAT( ) z/os 1.7 107 sec. z/os 1.8 9 sec. SETSMS COPYSCDS create an ACDS directly from a SCDS without also activating the SCDS DISPLAY SMS,SMSVSAM,DIAG(CONTENTION) displays any VSAM RLS latch contention USS Sending messages to the sysplex message log (/dev/operlog) Syslog daemon (Communication Server) will receive messages from Remote systems, apply a host filter, translate all text to EBCDIC and write them to /dev/operlog file /etc/inittab /etc/inittab file is same as used on other UNIX platforms /etc/inittab file is read and processed during USS initialization (IPL and OMVS restart) If the /etc/inittab file exists, it will be processed instead of the /etc/rc file Recommendation: start /etc/rc in /etc/inittab (should be the first entry); /etc/rc should remain, only start daemons from inittab F OMVS,STOPPFS=ZFS NFS Other stop commands no longer supported ( P ZFS or P MVSNFSC) 6

Neue Funktionen (4 / 5) Console Restructure Stage II 1-byte Console ID removed Removal of Master console (Console ID 0) VARY,MSTCONS no longer supported DISPLAY C,MCONLY no longer supported CONSOLxx INTIDS(Y) and UNKIDS(Y) to receive messages targeted to console ID=0 COMMNDxx use SETCON MN, instead of MN JOBNAMES,T Removal of Console switching VARY CN( ),ALTGRP no longer supported SWITCH CN no longer supported Chart-Nr. 8 Console restructure stage II toleration PTF OA10632 Removal of master console (console ID 0) When the first z/os 1.8 system joins a sysplex, support for the MC is removed for all systems in the sysplex. When the last z/os 1.8 system leaves the sysplex, a MC may again be selected (manually VARY,MSTCONS). All messages targeted for console id 0 will go to any console that has the INTIDS routing attribute. INTIDS may be specified in CONSOLxx or through the VARY CN command. DISPLAY C,MCONLY z/os 1.7: IEE889I NO CONSOLES MEET SPECIFIED CRITERIA z/os 1.8: IEE535I DISPLAY INVALID PARAMETER VARY,MSTCONS z/os 1.7: CNZ0004I VARY MSTCONS NOT SUPPORTED DUE TO CURRENT CONFIGURATION.

When the last z/os 1.8 system leaves the sysplex, console switching becomes operative. VARY CN( ),ALTGRP: IEE682I VARY COMMAND : UNEXPECTED ALTGRP IGNORED.

Neue Funktionen (5 / 5) XCF/XES CFRM CDS performance enhancements message based policy one system message-based manager New CDS format: ITEM NAME(MSGBASED) NUMBER(1) SETXCF START STOP,MSGBASED IPCS / Diagnosis SYSTRACE entry for slip with A=SVCD SLIP STOPGTF keyword Disassemble coding in IPCS AMBLIST JCL USS interface Chart-Nr. 9 XCF/XES CFRM couple dataset performance enhancement Eliminate I/O bottlenecks to CFRM CDS during critical system functions (system failure, recovery, structure rebuild, ). XCF now uses a message based policy (before: policy based). One system becomes the message-based manager. Activation: Reformat CFRM CDS with new option ITEM NAME(MSGBASED) NUMBER(1) SETXCF START,MSGBASED Rebuild structures to make use of the message-based protocol D XCF,STR and D XCF,C,TYPE=CFRM to get information about protocol type Fall back: EVENT MANAGEMENT: POLICY-BASED EVENT MANAGEMENT: MESSAGE-BASED MANAGER SYSTEM NAME: sysname SETXCF STOP,MSGBASED all structures use policy-based protocol now IPCS / Diagnosis SLIP can make s SYSTRACE table entry when it matches with A=SVCD so the exact time of the match can be determined. Stop a specific GTF trace with the ACTION=NOGTF if multiple GTF traces are active. Provide machine language decoding and reverse execution decoding using a specific set of register values in a dump. LIST 06F48B2C. ASID(X'024E') LENGTH(X'6A') INSTRUCTION allow a filename on AMBLIST control statements (LISTLOAD, LISTIDR, LISTOBJ) which targets z/os UNIX files, e.g.: //HFS1 DD PATH='/u/xgadjag/tools/',PATHDISP=(KEEP,KEEP) //SYSIN DD * LISTOBJ DDN=HFS1,MEMBER=hostname 9
