Qlik Replicate with Informix as source and full load with transactions on

lguevara — Thu, 30 Apr 2026 14:52:29 GMT

Hi,

I have Informix as a source and I want to execute a Full Load, but I notice that there is a restriction: 'All transactions should be manually stopped before starting a Full Load task. Transactions started during the Full Load operation will be cached.'

Since I cannot stop transactions on the source database, what are the recommendations?

thanks.

Hello @lguevara ,

This appears to be a timing issue. For example, when you start a task, it may take around 5 seconds to reach the RUNNING state. If there are no open transactions during that window, the startup should complete without issues.

If it’s difficult to find a quiet window during business hours, consider starting the task during off-peak periods instead.

Hope this helps.

John.

Hello @lguevara ,

Feel free to let us know whether the above workaround meets your needs.

If not, here are a couple of alternative options:

Option 1 – Have Qlik Replicate wait when locks are encountered
In Informix source endpoint adding an internal parameter lockWait (default is 0), setting it to a reasonable value (for example, 120 seconds). This allows Replicate to wait 2 minutes for open transactions to close before proceeding, if hits locks.

Option 2 – Allow dirty reads
Enable dirty reads on the source (IBM Informix). This may result in reading uncommitted or inconsistent data so it is generally not recommended.

Regards,

John.
