5 Cnversin prcess 1. What percentage f the riginal prgrams can be cnverted t Java? Caravel cnverts 100% f the surce cde. The cnversin prcess als includes the cntrl language (CLs and OCLs), Operating System functinality (WRKSBMJOB, WRKSPLF, etc.), data access and user interface. BASE 100 delivers a 100% pure Java applicatin that runs with exactly the same functinality as the riginal ne. The cnverted system can be deplyed n the same AS/400 r ptinally n different platfrms, (HW, OS and RDBMS), with a mdern and versatile user interface. 2. Which versins f RPG & COBOL n OS/400 d Caravel supprts? Fr an IBM Mainframe envirnment, which COBOL versins can be cnverted? RPG/COBOL n OS/400: RPG language: All versins RPG II, RPG III, RPG/400 and RPG ILE. COBOL language: COBOL/400. Embedded SQL is supprted in bth RPG and COBOL. IBM Mainframes: COBOL Language: ANSI COBOL 85, COBOL and COBOL II. COBOL CICS and embedded SQL are supprted. 3. Can Caravel translate cycle RPG prgrams? Caravel implements all cycle prgrams functinality by means f classes and methds in Java that allw keeping their behavir in a very effective way. 4. Is the translatin f the prgrams dne individually? That is, each riginal RPG/COBOL instructin translated int a Java instructin? Caravel translates each RPG/COBOL instructin int a methd that keeps the same functinality f the riginal. The translatin is dne instructin by instructin, nt in grups. The aim f the cnversin is t prduce a system easily readable by the riginal technical team. On the ther side, the Java prgrammers fund a 100% pure Java system, and they can wrk n in it as an rdinary Java system. The functinality f the cnverted system can als be invked via a Rest services mechanism. 5. Once the prgrams are cnverted, what types f develpment envirnments are they cmpatible with? The cnverted prgrams are 100% pure Java cde, s can be used n every standard envirnment available. Our custmers have successfully wrked with WebSphere, Eclipse, Net Beans, IntelliJ, JBuilder, amng thers. 6. Are the perating system cmmands implemented (the CL's)? A huge number f cmmands that are used in legacy AS/400 systems are implemented: CPYF, CRTPFM, AD- DLIBLE, MONMSG, OVRDBF, OVRPRT, OVRDSPF, etc. Caravel is a cnversin service that guarantees 100% f the riginal functinality; therefre, all cmmands needed t achieve this gal are implemented. In the exceptinal cases that any functinality nnexistent in Caravel is required, BASE 100 will prceed t develp and include it in the framewrk. Frequent Asked Questins 5

6 Cnverted system architecture 7. It is pssible t keep the AS/400 1 as a database server? Or as an applicatin server? If yes, wuld it be necessary t expand it? It is pssible t keep the AS/400 as bth, data server and applicatin server. Under Client-Server architecture, we can maintain the AS/400 as the database server, while the cnverted system runs n an pen platfrm. Same under i5/os, Linux r AIX, the AS/400, the applicatin server can be deplyed n it. The cnversin desn t require an expansin f the existing hardware. The perfrmance varies depending n the hardware cnfiguratin and the cmmunicatins infrastructure, as well n the characteristics f each system. The change in the hardware wuld be necessary nly in case f evlutin frm a ne-layer architecture int a tw-layer (Client-Server). 8. When I cnvert a prgram t Java, is the perfrmance f my applicatin faster r slwer? It is well knw that AS/400 is a very reliable and extremely high perfrmance platfrm. Every cmpnent f AS/400 has been designed t wrk tgether, fcusing reliability and perfrmance ver standardizatin r cmpatibility. S t maintain same perfrmance level in the new cnverted system, it is necessary an intensive use f technlgy and knw-hw. Fr ver 10 years, the BASE 100 technical team has analyzed the characteristics f many applicatins frm the reliability and perfrmance pint f view. Mdern pen systems ffer levels f reliability alike t the legacy systems, but perfrmance is always an issue that must be cnsidered. The fast evlutin f pen systems has increased perfrmance, especially when cnsidered related t csts. This fact and the sharp evlutin f Caravel technlgy have eliminated the prir perfrmance gap we fund several years ag. Nw, in many cases, the cnverted systems are faster than the riginal ne, just after an autmatic mdernizatin prcess and cnfiguratin tuning. Minr reengineering interventins can als be intrduced at any time t imprve perfrmance. Only in few cases mayr reengineering r platfrm mdificatins are required. When necessary, Caravel technlgy has develped many strategies t greatly imprve perfrmance. (Fr mre infrmatin please refer t the dcument: _Perfrmance_analysis_in_mdernizatin_prjects_v2). 9. Hw are the data areas implemented? The data areas are implemented cnverting them t SQL structures in a relatinal database. 10. Hw are the advanced print functinalities implemented? Caravel implements a number f Java-cmpatible extensins fr the Printer Files (PRTF) prviding mst f the functinalities f the AFP/400 mdule, such as: Image Printing, text, templates, bar cdes, etc. (Fr mre infrmatin please refer t the dcuments related t Caravel OS/400 Framewrk.) 1 AS/400 means als: S/36, S/38, iseries, System i. 6 BASE 100, S.A.

7 11. It is pssible t print lines and bar cdes using Advanced Printing Utility (APW)? Caravel includes mechanisms that generate the same functinality t print bar cdes. A table f crrespndence is defined between the riginal cdes (APW) and their equivalent fnts t btain exactly the same barcde. 12. What is the applicatin behavir when printing a large quantity f paper? And fr large data vlume batch prcesses? The largest batch applicatin migrated with Caravel was a emplyees payrll. The new migrated prcess required a shrt time t print all paper dcuments (lists, receipts, checks, duplicates, etc.). The database n which these prcesses are executed has a vlume f apprximately 24 GB. In any cases the migrated applicatins run in the same time windw r faster than the riginal AS/400 nes. Additinally, the new system includes all the facilities t use electrnic dcuments in very different frmats. 13. Des the cnverted applicatin require a specific applicatin server fr its executin? Caravel has n dependence f any specific applicatin server. Currently, all translated applicatins are cmpatible with the latest versins f mst cmmn applicatin servers, fr example: Tmcat. WebSphere WebLgic. JBss. 14. Which is the versin f JVM that Caravel supprts? Caravel supprts JVM up t versin Java 8 update Which is are the Servlet and JSP versins that Caravel supprts? Caravel implements the fllwing specificatins: Servlet 2.3 and JSP 1.1, 1.2 and Is it pssible t deply the cnverted system n an applicatin server, particularly WebSphere? Caravel cnverts t Java fllwing the guidelines f the standard J2EE architecture. Therefre, yu may deply the cnverted system n any applicatin server cmpliant with this standard. 17. Which HW and SW mdificatins are needed t use Swing applicatins? In rder t use the applicatins in Java with a Swing interface yu need a client PC with a Java Virtual Machine (JVM). The applicatin must be accessible frm the client PC. Data may reside n this server, n the OS/400 r n any ther server. 18. Which mdificatins are required t use Web applicatins? It is necessary a server with access t the Internet/Intranet cntaining a Java Applicatin Server. The server may be WebSphere r any ther server that fulfills J2EE standard. The wrkstatins will need a brwser (Firefx, Chrme and Internet Explrer, are supprted). 19. After migrating with Caravel, what shuld be dne t btain a 3-layer applicatin? After Caravel system migratin, the resulting Java applicatin can be deplyed in a Java Applicatin Server. This mde fulfills the requirements f 3-layer architecture accrding t J2EE rules. The new Client Layer will cnsist f a set f client java cmpnents (Java JSPs, CSS files, Javascript client cmpnents prvided by the Caravel cnversin prcess), the cnverted Java classes will be part f the Business Lgic Layer, finally the Data Layer Frequent Asked Questins 7

8 crrespnds database server and data, as well as the pssible stred prcedures. The riginal AS400 can be maintained as the database server, r a new external SQL database server can be selected as well. In this case, the riginal data will be migrated frm the riginal data structure and frmat t the new SQL database). 20. Is it pssible t btain a 3-tier architecture applicatin when cnverting with Caravel? Yes, a Caravel cnverted applicatin separates User Interface cmpnents frm applicatin behavir. It als separates the applicatin data access t the final data strage. As a result f this: The resulting applicatin can be custmized very easily by creating r mdifying User interface Screens. Sme prgram lgic can be quickly cnverted int a Java Web Service (SOAP REST). The target database server (riginal AS400 PF/LF files, Oracle, DB2, SqlServer, etc) can be changed withut mdifying anything in the applicatin. 21. After migratin f the applicatins with Caravel, hw cmplex is the integratin with WebSphere? The integratin is very simple due t the cnversin prcess that includes an applicatin structure with an architecture fully adapted twards its integratin with an applicatin server. BASE 100 has the experience after many prjects using this applicatin server. 22. Can Caravel migrate the existing data t any RDBMS r are there specific restrictins n the supprt fr target RDBMS? Caravel migrates twards the mst cmmnly used RDBMs n the market. Sme examples are: DB400, DB2, Oracle, Pstgress, MultiBase, SQL Server In all cases a JDBC driver is required. 23. Caravel migrates the system's security and the user identificatin f the riginal platfrm? The security aspects are is nt part f a migratin. Once the applicatin has been migrated t the new envirnment, is necessary t execute a Security Management Applicatin fr that platfrm (Operating system, Data base management system, etc.). 8 BASE 100, S.A.

9 Maintenance and life cycle 24. Is a specific training required, regarding the methds and classes develped by BASE 100? The classes used by BASE 100 are 100% pure Java, clearly structured, and d nt require any different knwledge that Java. Such classes are easily legible by an RPG r a COBOL experienced prgrammer. In every cnversin prject is included a training sectin riented t bth RPG/COBOL and Java technicians. 25. Besides the persnalizatin prvided with the Caravel migratin, which ther tls are required t further persnalize the applicatin? T persnalize a Swing interface can be used any standard Java platfrm such as WebSphere, Eclipse, JBuilder, Frte, etc. T persnalize an HTML interface, it is pssible t use any HTML editr available n the market. 26. Is the user interface f an applicatin translated autmatically by Caravel r des it have t be set up manually? The persnalizatin f the interface wrks as fllws: When translating an applicatin, yu can chse between having the user interface autmatically generated r persnalizing single screens accrding t the preferences f the custmer. In the first case, the way the screens will lk is based n certain transfrmatin rules that Caravel prvides and that allw t generate the equivalent HTML cde fr each field f the screen. The result will be an HTML cde that generates the same fields, sizes and psitins as the riginal. The clr attributes, surces, backgrund clr, etc. that desn t affect the functinality can be persnalized, being applied autmatically t all the generated screens. In the secnd case, the custmer can create a JSP template fr each screen that he wishes t persnalize. This template can have any aspect and des nt have t be similar t the riginal. With the purpse f making the preparatin f the screens easier, Caravel prvides the standard JSP mechanisms and uses the JSP TagLibs, which easily help with the use f the infrmatin frm the applicatin: recrds, sub-files, fields, attributes. Caravel als supplies the JavaScript functins in rder t manage thse fields and send the infrmatin back t the applicatin (fr example functin keys). This slutin prvides all the flexibility fr the designer t get the desired aspect. These tw slutins are nt incmpatible; it is pssible t persnalize nly sme screens f the applicatin. This prcess can be prgressive r accrding t the custmer's needs. The applicatin will search fr the persnalized screen first and then, if it cannt find it, dynamically will create a screen in accrdance with the parameters f the selected user interface. The persnalizatin prcess can be carried ut cmpletely by the custmer r culd be part f the prject. In this last case, the custmer can define the rules, standards and styles that he wuld desire. Since the aspect f the applicatin is defined by a grup f JSP templates, the custmer can change any graphical element at any time. Frequent Asked Questins 9

10 27. Hw can we avid surprises? At what pint in time exactly will we knw the wrk that has t be realized and the csts that it implies? Is that infrmatin available prir t the beginning f the prject? Des there have t be sme kind f analysis befre signing the migratin cntract? In the Caravel Standard Questinnaire are reflected all the variables that can determine the cmplexity f a cnversin prject. Befre start the prject, BASE 100 will evaluate the cmplexity and therefre, the resurces, time and csts f each prject. This estimatin is based in a big number f migratin prjects already cmpleted successfully. These prjects cver a great diversity f sizes, architectures and specific legacy technlgies. 28. When the Java applicatin translated by Caravel is deplyed n an AS/400, des it wrks withut using interactive card resurces? Yes, by default, yur migrated applicatins will lk like batch applicatins t the iseries, using ZERO interactive resurces. 29. Hw d yu handle multi-language applicatins? What additinal benefits d I get frm the migratin? If the riginal applicatin is multi-language, Caravel will migrate it with same functinalities. If the riginal is nt multi-language, during the translatin prcess, Caravel can be cnfigured t extract the literals inherent t language and exprts thse t an external file. By editing and translating that file, yu easily cnvert yur applicatin t a multi-language ne. 30. Can BASE 100 prvide a cmplete list f errrs (like missing surce, surce-bject mismatch, etc.) nce the Imprt is run n an applicatin? Yes, a cmplete and detailed analysis reprt is generated in the first cnversin phase. Caravel includes a specific tl Caravel Insight which des a cmplete inventry f all the legacy system cmpnents and analyses cmpleteness, relatinships, dependences, errrs, etc. The Caravel Insight reprt is a key piece in the cnversin prcess. 31. What brwsers d yu supprt? Firefx, Chrme, Internet Explrer. 32. Hw des Caravel reslve the cnnectins t external systems? (SAP, etc.) The cnverted Java applicatin has n limitatins cncerning future prgramming r cnnectivity. We have vast experience in this field. Typically it is necessary t cnnect the new Java applicatins with previus develpments made by that custmer. Usually every cnversin prject includes a part f integratin with ther existing r future systems. 33. What is Caravel s added value fr thse cmpanies that currently use r cnsider using slutins such as WebFacing, Hst Publisher, HATS fr iseries and web access? Caravel is nt merely a screen transfrmatin r a middleware. Our service is a prject t g t Java at nce. The features f WebFacing r HATS cannt be cmpared at all with a cmplete cnversin t Java and t pen platfrm. Our service migrates the whle applicatin t Java, then analyses it, structures it int cmpnents and imprves the applicatin with ur technical reengineering technlgy. Our apprach is much wider than an interface make-up with sme Internet cnnectivity prvided by the mentined prducts. Must be underlined, that the duratin time can be similar r ever reduced with Caravel. 10 BASE 100, S.A.

11 34. What des BASE 100 require t execute a cnversin prject f RPG r COBOL system t Java? BASE 100 requires a system that wrks crrectly in the legacy platfrm. It is necessary t have all the bjects t be cnverted (RPG and COBOL prgrams, CL, PF, LF with bth cmpiled and surce cde), and a set f data and a functinality descriptin f the riginal applicatin t be tested. BASE 100 prvides sftware tls (Caravel Test Maker) t help the custmer in this functinality descriptin prcess. 35. What des the custmer get after the Caravel migratin? BASE 100 delivers the Java applicatin ready t be run n the new platfrm and envirnment, with exactly the same functinality as the riginal system, that includes: The resulting Java surce and bject classes. The Xml files resulting frm the cnversin f the DDs file structures. A set f User interface cmpnents (JSP, css, images, etc.). A set f standard Java libraries (jar files) used by the applicatin. A database migrated cpy backup (in case f data migratin). Tgether with the abve, the custmer gets all the relevant dcumentatin abut the prject and the BASE 100 technlgy used, as well as specific training in the Java prgramming envirnment using Caravel techniques. 36. Is it pssible t migrate nly a part f an infrmatin system? Can prgrams develped in RPG/COBOL and Java cexists n the same AS/400? Yes, it is pssible t migrate nly a part f the system, this case is cnsidered in the Caravel technlgy. The riginal prgrams develped in RPG/COBOL n cnverted, can cexist with prgrams in Java. They can share data and platfrm. In these cases data nrmally remains in the AS400 as PF/LF data files that are access by bth, the riginal RPG/COBOL prgrams at the new cnverted t Java prgrams. 37. We will need t maintain the DDS/DDL database. Can yu give examples f the prcess fr ding this pst-cnversin (fr different bject types)? E.g. adding new fields t files. As a general rule, an AS400 physical file is migrated t SQL database table and a lgical File is cnverted t a Database Index. Each field is cnverted t a table clumn and the clumn type will be the mst apprpriated accrding t the riginal data type (this prcess can vary depending n the specific database Server). Additinally, an AS400 data file can define ther attributes like (packed/zned/binary numeric frmat, decimals psitins, frmat, default value, editing masks, etc). Lgical files can define fr example SELECT/OMIT cnditins. Mst f this infrmatin has n crrespndence t standard SQL attributes. Fr that reasn, Caravel generates als a XML file cntaining all the riginal DDS surce infrmatin (fr PFs/LFs, DSPFs and PRTFs). At runtime the cnverted prgram uses this infrmatin t generate the specific SQL statement r is used t cnvert the SQL data int the expected frmat. Fr that reasn if we change a cnverted database table, we have t d the fllwing tasks: 1. Mdify the Database table structure by executing the crrespnding ALTER TABLE instructin. 2. Add this mdificatin in the XML file that represents the data FILE fr the prgram. 3. Change the prgram that has t use these new fields accrdingly. (Fr example declaring and using the new recrd variables). Frequent Asked Questins 11

12 Licenses and Csts 38. Is there a dwnladable trial versin? Caravel is cmmercialized n a service base, therefre is nt cmmercialized as a tl. In case f a test is desired, the advisable way is t d a Prf f Cncept with a part f yur system. In the dcument Migratin prpsal and free PC, there is all the infrmatin abut hw t prepare a sample f the system. The general lines fr a PC are: Extract a cmplete wrking subset f the system, with prgrams and data. Send t BASE 100. Check the cnverted system thrugh web. It is advisable t chse thse parts f the system that the custmer estimates as mre critical. 39. Can Caravel be purchased under license as a translatin tl? Caravel is a migratin service, with the cmmitment t deliver the Java applicatin with exactly the same functinality. Cnsequently ur business mdel des nt include selling ur translatin tls t a third party. Several ther tls included in the Caravel technlgy family such Caravel Insight can be purchased as a tl. 40. Please validate this understanding: that the use f yur prduct des nt impse any additinal license requirements n the migrated prduct, r nce the applicatin has been translated t Java, there wuld be n need t use the tl in the migrated envirnment? After the cnversin prcess it is nt necessary the use f any tl. The migrated prgrams are 100% Java. Our migratin service prvides ttal independence t ur custmers. Our business mdel des nt include payments after the cnversin itself. We prvide detailed infrmatin in ur cmmercial prpsals abut the cst f every item. Optinally is pssible t subscribe maintenance updates and maintenance services fr the Caravel Framewrk. Bth are included in the cnversin fees, during the first year after the cnversin prject. 41. Hw much des a Caravel migratin cst, apprximately? Our pricing plicy depends n the prject size and cmplexity. We can give a precise estimate after the evaluatin questinnaire has been cmpleted and sent back t us. In case yur cmpany des nt knw the exact vlumes, we can prvide an estimate based n a representative mdel. Our pricing plicy allws fr ROI in a maximum f 12 mnths. The cst advantage f Caravel translates int 1/7 f the cst and 1/5 f the time needed fr a re-prgramming prcess. 12 BASE 100, S.A.

13 Java Technlgy 42. What is a class in Java? In an bject-riented language; a class is a prgram that implements the functinality relative t a specific type f bject. Such functinality cnsists f methds and prperties. 43. What is a methd in Java? A methd in an bject-riented language is a type f functinality f an bject class. 44. What is the J2EE standard? J2EE (Java 2 Platfrm Enterprise Editin) defines the standard fr develping cmpnent-based multitier enterprise applicatins. There are tls that create a perfect setting fr the develpment and deplyment f scalable applicatins fr the Web. These tls have the fllwing features: 1. Prtable. Just by writing the applicatin in Windws r Linux, it will be available n any platfrm that has a Java Virtual Machine (JVM). 2. Scalable. When the cmpany's vlume grws, the additin f new J2EE cmpnents t the Web applicatin will suffice t supprt the grwth. There is n need t rewrite the cde. 3. Highly Supprted. Any large sftware cmpany has a Web cmpnent cntainer (r applicatin server) cmpatible with J2EE, such as IBM (WebSphere), BEA (WebLgic), Apache (Tmcat), Sun (iplanet), Macrmedia (Jrun), etc. 4. Secure. While ther business applicatin mdels require specific security measures in each applicatin, the security envirnment f the J2EE platfrm allws the definitin f security restrictins at the time f deplyment f the applicatin. Thereby, the cmplexity f the security implementatins is islated. J2EE makes cmplex security implementatins prtable. 45. Is it pssible t integrate ther Java applicatins nce the migratin has been dne? Yes it is, the cnverted system adheres 100% t the standards f Java applicatins. Frequent Asked Questins 13
