From Zero <strong>to</strong> z Hero - z/OS und <strong>XML</strong> - Das perfekte Duo<strong>XML</strong>: Why it's this way• Simple (like HTML -- but not quite so simple)– Strict syntax rules, <strong>to</strong> eliminate syntax errors– syntax defines structure (hierarchically), <strong>and</strong> names structural parts(element names) → self-describing data• Extensible (unlike HTML; vocabulary is not fixed)– Can create your own language of elements (aka "tags")– Strict syntax ensures that such markup can be reliably processed• Designed for a distributed environment (like HTML)– Based on Unicode text– Each <strong>XML</strong> parser must be able <strong>to</strong> parse <strong>XML</strong> encoded in Unicode• Can mix different data types <strong>to</strong>gether (unlike HTML)– Can mix one set of elements with another set: resulting data can still be reliablyprocessed© 2012 IBM Corporation

From Zero <strong>to</strong> z Hero - z/OS und <strong>XML</strong> - Das perfekte DuoOptions, options, options!<strong>XML</strong> parsing options for z/OS• These alter<strong>native</strong>s have various characteristics in terms of:– Functionality– St<strong>and</strong>ards support– Performancethat should be considered when you are choosing a parser <strong>to</strong> be used for a specificsituation.• Also, keep in mind that often there is higher-level processing available that removes theburden of you needing <strong>to</strong> parse <strong>XML</strong> data yourself.© 2012 IBM Corporation

From Zero <strong>to</strong> z Hero - z/OS und <strong>XML</strong> - Das perfekte DuoKicking down the costs of <strong>XML</strong>• We know that the cost of <strong>XML</strong> processing is high, so anything that helps reduce that cost isgood news, right?• With z/OS V1R9 or higher, <strong>and</strong> through a PTF for V1R7 <strong>and</strong> V1R8, z/OS <strong>XML</strong> SystemServices is now able <strong>to</strong> take advantage of the lower-cost zAAPs <strong>to</strong> help reduce the cost ofcomputing when parsing an <strong>XML</strong> document.• The system does this zAAP enablement under the covers when any program calls the main<strong>XML</strong> parser module, GXL1PRS (GXL4PRS), or its new C/C++ equivalent service for z/OSV1R9, glxpParse().• After the parser completes its processing, the system turns off zAAP enablement.• IBM added support for zIIPs <strong>to</strong> the <strong>XML</strong> System Services (z/OS <strong>XML</strong>) parser. With thissupport, the parser will be redirected <strong>to</strong> the lower-cost zIIPs when running in enclave SRBmode. With respect <strong>to</strong> DB2, processing that can be partially directed <strong>to</strong> zIIPs like DB2Distributed Relational Database Architecture (DRDA) benefits by directing the full amount ofthe z/OS <strong>XML</strong> System Services processing <strong>to</strong> the zIIPs.• IBM added parser validation support <strong>to</strong> z/OS <strong>XML</strong> System Services, <strong>and</strong> <strong>to</strong> enhance the<strong>XML</strong> Toolkit for z/OS so that eligible workloads can exploit z/OS <strong>XML</strong> System Services.• Both of these additions will exploit the ability of the z/OS <strong>XML</strong> parser <strong>to</strong> use zAAPs.© 2012 IBM Corporation

From Zero <strong>to</strong> z Hero - z/OS und <strong>XML</strong> - Das perfekte Duoz/OS <strong>XML</strong> System Services (z/OS <strong>XML</strong>)• z/OS introduced direct support for <strong>XML</strong> parsing with z/OS <strong>XML</strong> System Services• z/OS <strong>XML</strong> System Services is an integral part of the z/OS operating system <strong>and</strong> wasdesigned <strong>to</strong> provide <strong>XML</strong> parsing assistance with minimal path-length• There is no need <strong>to</strong> download or install any additional packages <strong>to</strong> use it.• From the application perspective, z/OS <strong>XML</strong> System Services is a set of callable routinesthat parse (or validate <strong>and</strong> parse) an <strong>XML</strong> document, rendering its contents in<strong>to</strong> anintermediate format that is easily navigated.• Applications can focus on business processing <strong>and</strong> rely upon z/OS <strong>XML</strong> SystemServices <strong>to</strong> h<strong>and</strong>le the intricacies of a<strong>to</strong>mizing an <strong>XML</strong> document.• z/OS <strong>XML</strong> Systems Services does not use or provide SAX or DOM interfaces.• It is a buffer-oriented interface that allows the input <strong>XML</strong> <strong>to</strong> be provided in pieces <strong>and</strong> theparsed result <strong>to</strong> be consumed in pieces.• There is no limit on document size using this approach.• Documents of many gigabytes can be processed.© 2012 IBM Corporation

From Zero <strong>to</strong> z Hero - z/OS und <strong>XML</strong> - Das perfekte DuoGeneral performance recommendations for <strong>XML</strong> Parser components• Use DTD <strong>and</strong> schema grammar caching <strong>to</strong> reduce the cost of validation• Turn validation off when not needed <strong>and</strong> avoid DOCTYPE clauses• Use special scanner when document validation type is known (default document scannerIG<strong>XML</strong>Scanner; special scanners are WF<strong>XML</strong>Scanner for well-formedness checking only,DG<strong>XML</strong>Scanner for DTD validation only, <strong>and</strong> SG<strong>XML</strong>Scanner for schema validation only )• For best validating performance, use a DTD instead of a schema• Use external entities <strong>and</strong> external DTD's only when necessary (extra file opens <strong>and</strong> thetranscoding setup they require is expensive)• Avoid multiple parses of the same document (f.e. s<strong>to</strong>ring the results of the initial parse in aformat which may be efficiently accessed at a later time)© 2012 IBM Corporation

From Zero <strong>to</strong> z Hero - z/OS und <strong>XML</strong> - Das perfekte DuoGeneral performance recommendations for <strong>XML</strong> Parser components• Reuse the initialized parser• Avoid unnecessary document conversions• Reduce character count• Pre-normalize line end characters (two character sequence x'0D0A' <strong>and</strong> any occurrence of asolitary x'0D' with the single character x'0A' )• Avoid using default attributes• If possible, use SAX instead of DOM, especially when parsing large documents• S<strong>to</strong>re your <strong>XML</strong> documents in the z/OS or OS/390 UNIX HFS© 2012 IBM Corporation

From Zero <strong>to</strong> z Hero - z/OS und <strong>XML</strong> - Das perfekte Duo<strong>XML</strong> Parser, C++ Edition performance recommendations• If your applications are compiled with the XPLINK option, use the XPLINK version of the<strong>XML</strong>4C parser.• Use the new DOM bindings• Disable namespace support if not needed• Be careful when using getElementsByTagname("*").getLength()– This method walks the entire DOM tree <strong>to</strong> count the number of elements. If your DOM islarge, this can be expensive• Pass fully qualified pathnames• Optimize your Language Environment parameters– The important parameters <strong>to</strong> specify are HEAPP(ON), LIBS(1K,1K,Keep), <strong>and</strong>STOR(,,,8).– You may also need <strong>to</strong> override the sizes of HEAPS <strong>and</strong> STACKS if more s<strong>to</strong>rage isrequired.• Follow z/OS <strong>and</strong> OS/390 UNIX, C/C++, <strong>and</strong> Language Environment guidelines© 2012 IBM Corporation
