We are planning to use always on job, which will be accessed by concurrent users. The reference data with minimal number of columns is around 2 GB. And when we expose this job as webservice, we might need minimum 3-4 instances of the service running in ISD for supporting concurrent requests. Since i...

Ray, The deisgn is for a web service, where we will have one request (one record), which will have to find records in a reference database where we have few million rows. So I thought Sparse is a best fit here. And the performance I am talking about is firing the query on database and get the result...

We are planning to use this sparse lookup in a DataStage Job that will be exposed as a web-service. The web-service performance should be very high. These are the two options I am thinking of 1) use ODBC connector and do a sparse look on Mainframe db2. 2) Load Mainframe db2 data into local aix db2 a...

Sparse lookup on Mainframe db2 using Db2 connector
Can we do Sparse look-up on Mainframe db2 table. As per my understanding DB2 EE stage in 7.5 does not connect to Mainframe and DB2 API does not support sparse look-up.
Do we have any extra features in v8.1 to do a sparse look-up on Mainframe db2

Complex Mainframe Parsing
I have a COBOL File coming from mainframe as follows: 1) Contains 60 different record types. 2) Record type can be identified based on a fixed header field 3) Based on header field, identify the record type and we have separate copybook for each record type. eg: For record type 99, the data will be ...

Ernie, Thank you for your explanation. I will try with database and sparse lookups. SURA, Please find answers for your questions. 1. How much changes will you expect a day? The web service would be used at enterprise level and we are having huge number of users who will be invoking it. 1a. How frequ...

Design for real time reference data update.
We have created a webservice for customer search (both deterministic and probabilistic matches). The customer will be searched on a reference data of 200 million records. Currently we have designed the webservice for static reference data which needs to be updated for realtime scenario. Current desi...
