Plan Analyzer is generating bind cards with PLANMGMT OFF when the Zparm set to EXTENDED. How or what controls the Plan Analyzer bind card settings?
Plan Analyzer obtains the PLANMGT value from catalog not from the ZPARM. If you want to change the PLANMGMT settings for a package in the catalog, the rebind options allows the package to be changed from OFF to EXTENDED for PLANMGMT. The line command to use for rebind package options is RO.
