CDC problem with 21C

Dear All,i am trying to create 2 pipelines from Oracle to Postgres.the first one is initial Oracle to Postgres, it worked very well, and schema conversion tool migrated 2 example tables to postgres. but i have an issue with Oracle CDC.i have logminer user on oracle which is striim and i have table owner which is scale_user and i have 2 tables scale_data and scale_data2.i am not using container and PDB on 21C, striim and scale_user are common user.i am receieving an error like below when i insert a data to the tables after commit.i see that reader is looking for tables like CDB$ROOT.TEST.SCALE_DATA but i am not using container so how can resolve the issue.There was no problem with initial load, the problem is related with CD process. Thanks in advance. [{ "_id" : null, "timeStamp" : 1707166962232, "originTimeStamp" : 1707166964000, "key" : null, "sourceUUID" : { "uuidstring" : "01eec465-3101-b301-b854-42010a9c000a" }, "data" : [ "862412", "1", "1", "460" ], "metadata" : { "RbaSqn" : "50

Parallel Threads causes out of order events during CDC [SOLVED]

we’ve observed a number of lost updates when running CDC. The state of initial load seems fine, but later on we came across NO_OP_UPDATES. I’ve ignored the exception for the CDC, but that resulted in some of the updates being lost and records left in stale state.It seems that it might be connected with updates being in the same batch as the initial insert. How are events ordered within a single batch? Have you observed such scenarios? Source is SQL Server and target is Postgres in case thats relevant.

adjusting timezone

I’d like to convert a timestamp from location specific one (in areas that have summer time change) to UTC. What would be the best way to do it within Striim? I assume it’s doable using Joda API and I can see in the reference that “Striim supports all date functions natively associated with Joda-Time.” but I didn’t find an example how to call those Joda Time functions

CDC Postgres UUID to SQL Servers uniqueidentifier

Hi all, I’m trying to set up a CDC from Postgres(GCP Cloud SQL if it makes any difference) of a table with a UUID column to a SQL Server table with uniqueidentifier column. The wizard says it’s not possible. I’ve tried mapping the tables manually, but all the rows end up being discarded. Is there any way to make it work? Similar migration in the opposite direction works.

Soft Deletes in Striim

How do I handle soft deletes in Striim? Does Striim performs an update process to mark some data as deleted instead of physically deleting it from a table in the database?
