![]() APAR status Closed as program error. Error description In two phase resource - after performing update to a one phase resource (2-phase only performing select) is failing with: TransactionIm E WTRN0063E: An illegal attempt to enlist a one phase capable resources has occurred. The same code worked in 3.5 is failing in 5.0Local fix Problem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server 5.0 users of * * Tx with mixed 1PC and 2PC resources. * **************************************************************** * PROBLEM DESCRIPTION: Enable use of 1PC Resource with 2PC * * Resources if 2PC are read only * **************************************************************** * RECOMMENDATION: * * * **************************************************************** It is valid to enlist a one Phase Commit resource into a global transaction with other 2 Phase Commit (XA) resources and to have the 1PC resource successfully commit as long as all of the 2PC resources are used as read only resources. This Interim Fix corrects the situation where the enlistment of the 1PC resource is rejected if 2PC resources are already in the transaction. A 1PC resource can now be enlisted with 2PC resources, if however any 2PC resource is not used for read only the WTRN0063 message is given at transaction prepare time and the transaction rolled back. If update capability is required to both the 1PC and 2PC resources then Last Participant Support of the WebSphere Enterprise product should be used.Problem conclusion Moved 1PC/2PC check from enlistment to prepare and relaxed in the case when 2PC resources are read-only.Temporary fix Interim Fix PQ72718 available.Comments
