Parameter documentation

If you use the parallel ALTER function (see SAP Note 960392), an instance number is used to identify a parallel alter lock manager. Each SAP system <(><<)>SID> on a database host (iSeries) should have its own lock manager. By default, the message server port number module 100 is used. For example: sapmsB4L with a port number of 3642 would have a parallel alter instance of 42. Example: dbs/db4/parallel_alter_instance = 42 Include this profile parameter in DEFAULT.PFL. The current value is included in the developer trace: parallel_alter_instance = 42 See SAP Note 960392
