Get feedback from the IBM team to refine your idea
Help IBM prioritize your ideas and requests
The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.
Receive notification on the decision
Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.
Replicate Timezone portion for timestamp with time zone data type
IIDRCDC for PostgreSQL Source is relatively new IBM product that replicates data from PostgreSQL database. In this particular scenario, source is PostgreSQL and target is flat file using IIDRCDC Datastage product.
Per IIDRCDC datatype support document, "Timestamp with time zone" data type is supported by IIDRCDC PostgreSQL Source and IIDRCDC Datastage flatfile target.
By default, IIDRCDC flatfile target can only produce output up to second precision ( 2 digit seconds). Microseconds portion of timestamp can be produce using IBM's sample userexit program as describe below.
PostgreSQL DB "timestamp with time zone" value => 2021-06-14 12:45:02.936025-04
Default IIDRCDC Datastage flatfile value => "2021-06-14 12:45:02"
IIDRCDC Datastage flatfile using IBM's sample userexit => "2021-06-14 12:45:02.936025"
At this time, there is no method or sample userexit that can produce "time zone" (-04) information in the flatfile output.
As more applications and databases using "timestamp with time zone" data type, this should be part of default IIDRCDC Datastage flatfile output. "Timestamp with time zone" is critical datatype to identify records order and handles applications or databases in different time zones. At least, IBM should provide some kind of sample program that customer can use to have this functionality in the target flatfile.
This is very crucial functionality for IIDRCDC if target data is used for frauds, audits, analytics or warehouse applications. This request is to provide some kind of solution for this problem
