Problem summary
**************************************************************** * USERS AFFECTED: 1. All User * * 2. All MFA users with compound delimiter ; * * 3. All users that their operations have * * put a lock on data set during their * * connection * * 4. All users * **************************************************************** * PROBLEM DESCRIPTION: 1. In Explorer for z/OS 3.4.3, when * * a user logs in after a host upgrade, * * a directory, private_common_properties, * * is created under the z/OS Explorer * * user's OMVS home directory, even if * * the feature is not enabled in rse.env. * * 2.

A directory, private_common_properties, is created under the z/OS Explorer user's OMVS home directory, even if the feature is not enabled. 2. There is an issue in the host component that chokes on ";" separator used in MFA compound login credential. 3. In IBM Developer for z/OS (IDz) version 17.0.4, when a user logging off the MVSLockOwnershipTracker reports a ZFile delete operation failure. in the rseserver log with the following exception: ERROR: MVSLockOwnershipTracker : ZFile delete operation failed for 'MY.JCL(TEST)' lock record (1 of 5 times) in '//'MY.IDZ170.LOCK.VSAM'': 'com.ibm.jzos.ZFileException: //'MY.IDZ170.LOCK.VSAM': fread() failed; EDC5028I A previous I/O error has marked the stream invalid for further I/O processing.; errno=28 errno2=0xc0500040 last_op=116 errorCode=0x80010:EDC5028I A previous I/O error has marked the stream invalid for further I/O processing.' 4. In IDz 17, when collecting feklogs, users noticed the error message in their feklogs stating both attls_policy & enble_ssl can not be enabled at the same time when only enble_ssl is enabled. ERROR enable_attls_policy has an invalid value ERROR enable_attls_policy and enable_ssl cannot both be TRUE
Problem conclusion
1. Add a check for the RSE_COMMON_PROPERTIES environment variable to verify whether the service is enabled. If the service is not enabled, do not create the private common properties. 2. Parsing issue was fix. MFA user now could login using their credential with ";" MFA separator 3. RSE lock information tracker cache needs to be updated properly when locks are released so that they are not . 4. A typo in checking condition causing the error in the second error message; it does not affect the encryption functionality of the product. A fix is delivered. Note: the first error message is expected for a property, here enable_attls_policy, when it is not set
