IBM iDB2 How to set the schema to *LIBL so Trigger are called from different libaries

I am running into issue Updating a table in IBM As400 which has triggers in different library.

It can be solved if I can set environment to libraries before calling the Update procedure. I am getting locking issues because trigger is in different library than default. Another way I call solve is by calling a Procedure which will set the environment before calling the Update.

Hope anyone who worked in AS400 can answer this.


Version OS 10 + IBM iSeries
