Consumer task with full load and CDC sourcing from logstream

unay — Thu, 07 May 2026 19:39:39 GMT

Hello Qlik community,

We have a user who does full load sourcing from Logstream task. Logstream task is sourcing from DB2 zo/s and they have 1 week of data retention.

We see consumer task is sourcing from Logstream explicity while it also has feature to enter Db2 zo/s credentials and the users entered those and the test connectton was successful.

Question : How is full load done here. Is it sourced from DB2 zo/s or sourced from the Logstream task (staging area).

Please advise !

Thank you,

Pranathi

Hello Pranathi, @unay

In this scenario, the Full Load data is read directly from IBM DB2 for z/OS and replicated to the target, rather than flowing through LogStream. That is why you still see connections to Db2 z/OS during the Full Load phase.

By the way, even during the Change Processing phase, Replicate still maintains connections to Db2 z/OS, as these connections are used for metadata retrieval, DDL change monitoring, and other control operations.

Hope this helps.

John.
