IBM i Why use IASPs? § Single System Environment – isolate and consolidate – – Multiple Applications Multiple versions of same application Server consolidation Data archive § Multiple System Environment – Fundamental building block of hardware and OS-based High Availability and Disaster Recovery solutions – Off-line backups from replicated copy – Replicated copies for testing or development § Common (general) – Isolation of data associated with specific applications – Increased granularity of management scope IBM i Technology Center (i. TC) © 2009 IBM Corporation
IBM i Building Blocks: IBM i IASPs ASP 1 (SYSBAS) § Independent ASPs (IASPs) * –Uptime ► Shorter IPL – leave non-critical IASPs offline till after IPL ► RCLSTG by asp –Archive ► Storage User ASP performance and cost by IASP –Consolidation IASP – Application -1 ► Consolidate with IASPs - Meet compliance needs for isolation - Reduce software licensing fees - Reduce number of OS upgrades –Clusters IASP – Application -2 ► Building block for HA/DR storage replication based clustering Reduce archive costs with lower cost storage in IASP – Journaling * IBM sometimes refers to IASPs as Independent ‘Disk Pools’ IBM i Technology Center (i. TC) © 2009 IBM Corporation
IBM i IASPs in a Single System Environment ü Can be any server that supports V 5 R 3 ü Isolate low-use data - bring online only when needed ü Reduce system start time ü Manage save/restore by IASP ü Reclaim storage by IASP ü Divide data between multiple databases ü Isolate data Ÿ Isolate affects of disk failures ü Application maintenance does not affect entire system IBM i Technology Center (i.

TC) © 2009 IBM Corporation
IBM i IASP HA Solution Considerations § IBM’s HA solutions and technologies for i are continuing to center around IASPs. § HA system/partition is available while in the “Contingency” role. – Is a unique system, not a complete replica of the source system – Unique instance of i operating system, LPPs, PTFs, etc – System is available, but IASPs replicated or shared from a “primary” system are NOT available unless switching or failing to contingency system. § If using OS or Hardware Based replication of IASP, processes will need to be in place for synchronizing necessary SYSBAS objects and settings § May need changes to processes such as change management, user and security management, system monitoring, etc. IBM i Technology Center (i. TC) © 2009 IBM Corporation
IBM i How do you get there? Common Changes and Application Considerations for IASPs IBM i Technology Center (i. TC) © 2009 IBM Corporation
IBM i Typical IASP Migration Project Outline § Determine how IASPs fit into your HA/DR/Server Consolidation/Offline backup strategy. § Perform initial proof-of-concept on subset of applications. § Educate administration and programming staff on IASP enablement considerations. § Set up test environment where application and work management changes for IASP enablement will be performed and tested. § Devise plan for synchronizing SYSBAS between primary and secondary systems, if applicable. § Test all process, application and work management changes. § Determine production migration strategy based on available hardware and replication options. § Test migration process on sandbox environment, if possible § Perform any necessary education to support personnel and users on process change, etc. § Execute production migration and implement revised HA strategy based on IASPs, if applicable. IBM i Technology Center (i. TC) © 2009 IBM Corporation
IBM i IASP Enablement Considerations § Most changes to support IASPs are typically work- management oriented. IASP migration can generally be transparent to most end-users. § Location of application objects – data, journals, journal receivers – programs and environment definition objects – considerations for object types not supported in IASPs § Setup considerations – Loading of IASPs § Work management considerations – Name space, library list, job initiation, etc. § Application run time considerations – Database connectivity – DDM, JDBC, ODBC – Commitment control scope, join logical files § Additional considerations for multiple IASPs on a system IBM i Technology Center (i. TC) © 2009 IBM Corporation
IBM i Location of Application Objects *SYSBAS ASP Group § Objects not supported in § Permanent application data § Exit programs, etc. that § Spool files (maybe) objects IASP must be found in *SYSBAS § Operational version of job receivers control objects (SBSD, etc) § Temporary objects § System libraries § Application program § Journals & journal § Definitional version of job control objects (SBSD, etc) § Application program objects ? IBM i Technology Center (i. TC) © 2009 IBM Corporation
IBM i IASP Set-Up Considerations § Decide whether program objects will be in *SYSBAS or in IASP § Evaluate IFS directories and files to move to IASP – Create symbolic links in old *SYSBAS IFS location, pointing to new location in IASP § Populating IASPs with data – Use ASPDEV since RSTLIB default will put objects in *SYSBAS – Permanent SQL objects cannot span IASP boundaries – Cannot create files, tables, etc. into QSYS 2 nnnnn – Journal objects must be in same ASP group as objects being journaled § Create new companion libraries for library content to be split between *SYSBAS and IASP § Modify startup program to vary on IASP IBM i Technology Center (i. TC) © 2009 IBM Corporation
IBM i IASP Work Management Considerations § Determine how application will access specific IASP (name space): – Job descriptions INLASPGRP – most transparent to users – SETASPGRP – SQL Connect, etc § Modify JOBDs for USRPRFs – Set initial ASP Group for user profiles associated with the application § Library list processing § Evaluate SBSDs for changes or attachment to IASP – AJEs, PJEs, JOBQs, Routing programs IBM i Technology Center (i. TC) © 2009 IBM Corporation
IBM i IASP Database Considerations § Views, tables cannot span IASP boundary – No join logicals over physicals in different ASPs or ASP and SYSBAS § Commit block cannot span IASP boundary – If connected to IASP RDB, cannot commit changes against both IASP and *SYSBAS (except QTEMP) § Decide on RDB name for IASP – Single IASP on system, may want to give the old *LOCAL RDB name to the IASP instead. § DDM files – Configure to use *RDB for connectivity § New permanent libraries or collections for application: – CRTLIB LIB(library-name) ASP(*ASPDEV) ASPDEV(asp-device-name) – Create collection – default for INASP is the current library name space § JDBC, ODBC, FTP connectivity – Use JOBD of USRPRF to set INLASPGRP where possible IBM i Technology Center (i. TC) © 2009 IBM Corporation
IBM i IASP Application Considerations § Switching name spaces (SETASPGRP): – Typically avoid from within application – If use, release locks and pointer references first § IASP offline – if program objects remain in SYSBAS: – Application time out may need to increase for vary on processing – Application must handle object not available (as result of vary off, etc. ) § Evaluate use of SBMJOB and any commands with ASPDEV parameter to ensure desired behavior § Can use Vary on/off exit programs for IASP to perform application startup and shutdown processing IBM i Technology Center (i. TC) © 2009 IBM Corporation
IBM i New Function added in i 6. 1 IBM i Technology Center (i. TC) © 2009 IBM Corporation
IBM i New i 6. 1 IASP Related Enhancements § Support of job queues in IASP – Allows applications to run with IASP with fewer changes – Job queue entries not persistant § Support for associating an IASP with a subsystem description – Parameter added to subsystem description object – IASP must be available for subsystem to be active § Quiesce function – i Suspends transactions & operations to ensure that as much in-flight data as possible is written to disk § Support for pure SYSBAS transaction under commitment control – Can open commit transactions against SYSBASE in a job with an IASP in the namespace – Commit transactions still cannot cross SYSBASE/IASP boundaries § Avoiding IPL in previous cases where IASP could not be varied on § Encrypted IASPs – 5761 -SS 1 Option 45 - Encrypted ASP Enablement required IBM i Technology Center (i. TC) © 2009 IBM Corporation
IBM i Support for Job Queues in IASP § Job queue object can be created in IASP – Allows applications to run with IASP with fewer changes § Operationally, identical to JOBQ in SYSBAS: – User can manipulate jobs (submit, hold, release, etc. ) on JOBQ – User can manipulate JOBQ (clear, hold, release delete, etc. ) § Behavioral differences exist: – Jobs on JOBQ in IASP will not persist across vary off / vary on – Jobs on JOBQ in IASP will not be available on backup system after switchover or failover IBM i Technology Center (i. TC) © 2009 IBM Corporation
IBM i Quiesce Function § Suspends transactions & operations to ensure that as much in-flight data as possible is written to disk – Places transactions at database boundaries if possible ►Use commitment control for maximum effectiveness § Operates against individual IASPs or *SYSBAS § Useful prior to Flash.

IBM i Encryption for ASP § Protects data transmission to and from the disk drive (important in a SAN environment). § Protects data transmission in the cross site mirroring environment (only when the data being mirrored is on an encrypted independent disk pool). § Protects data in the case of theft of the disk drive. § Protects data in the case of return or resale of a disk drive (reduces the need to sanitize the disk drive). § Must be specified at IASP creation time – cannot be applied to existing IASPs. 5761 -SS 1 Option 45 - Encrypted ASP Enablement required IBM i Technology Center (i.

IBM i Sample ISVs with announced IASP Support § Oracle – JD Edwards World and Enterprise One § SAP § Lawson M 3 § SPSS § Soft Landing § Vision Solutions § Manhattan § Many others have been implemented in clients IBM i Technology Center (i. TC) © 2009 IBM Corporation
IBM i Steps to Enable Oracle’s JD Edwards World A. 73 in an IASP Environment 1) Create the IASP by indicating in i. Series Navigator the unconfigured disk drives that should be in the IASP. 2) Identify the JD Edwards application libraries to be moved into the IASP. Eg JDFDATA, JDFOBJ, JDFSRC, CLTCOM, CLTDTA, CTLSEC. JDFINS library was left in *SYSBAS because it contains JOBQ objects which weren’t supported in IASPs at time of publication of article. 3) Move the libraries to the IASP by saving the libraries to tape or Savefile(*SAVF), deleting them, and restoring them to the IASP by specifying the ASPDEV parameter on RSTLIB command. 4) Modify the JOBDs that JD Edwards uses to point to the IASP group created in step 1 eg CHGJOBD(<libname>/<jobdname>) INLASPGRP(<IASPname>) INLLIBL(QGPL, TEMP, rest of libraries) http: //www-03. ibm. com/support/techdocs/atsmastr. nsf/Web.
