Error description
z/OS Debugger service 17.0.2.1 for IBM Developer for z/OS Enterprise Edition 17.0.2 IBM Developer for z/OS 17.0.2 IBM Debug for z/OS 17.0.2 IBM Test Accelerator for Z. --- Features --- See "What's new in IBM z/OS Debugger" in the z/OS Debugger documentation for any new features, if any, included in this service. --- End Features --- --- Service --- -Test Accelerator for z/OS (TAZ) recording for a batch DB2 COBOL program compiled with COBOL II (non-LE COBOL) will result in abend U4038. EQARCL4 offset X'1AA732'. (PH66791 at 17.0) -ABENDS0C4 at EQA00STO+188 during TAZ recording. (PH67125 at 17.0) -Loop in EQA00EHI during TAZ recording. On intercepting a DLI call, the debugger scans the save-area chain for a DSA that points to a known compilation unit. If the DLI call came from a program that is not known to the debugger, the scan may go past the top of the chain and continue looping at the zero DSA address. (PH67124 at 17.0) -ABENDS878-14 in EQANIPSB using IMS Isolation in IMSPLEX with multiple systems. Abend 878-14 is due to a request for a negative amount of storage. The value of the counter of classes reserved for IMS isolation became negative. The code that synchronizes isolation tables among IMS systems in a plex decrements the count when a class is removed but does not increment it on addition of a class. (PH67077 at 17.0) -DPS subtask denied access to ATTRBOUT when RACF TEMPDSN class is active. A user thread in the profile service allocates ATTRBOUT as a temporary file, then attaches a subtask to store data in it. The subtask inherits the security environment of the DPS job, different from the user's. If the TEMPDSN class is active at the site, and the file is allocated on disk rather than to VIO, the subtask is denied access to the file. (PH67284 at 17.0) -TAZ test case fails with RC-4 because of a mismatched SORT statement. (PH67496 at 17.0) -Debug Profile Server - Startup fails with RC=0256. If the work directory (/var/debug or $WRKDIR ) uses extended ACLS then EQAPROF server will fail to deploy and return. Error: Permissions for '/var/debug' do not match expected 'drwxrwxrwt'. Found 'drwxrwxrwt+'. (PH67101 at 17.0) -Debug Profile Service fails to authenticate users with mixed-case passwords during generate JWT token requests. (PH67303 at 17.0) -Debug Profile Service cannot customize Swagger UI Server URL for AT-TLS and Hostname Overrides. Incorrect Protocol Displayed with AT-TLS When using AT-TLS to handle SSL encryption at the TCP/IP stack level, Liberty is unaware that the connection is secure. As a result, the server URL reported by Swagger UI shows http instead of https. Any attempt to execute an API request from Swagger UI will generate a curl command using the incorrect protocol resulting in the following error: Failed to fetch. Possible Reasons: CORS Network Failure URL scheme must be "http" or "https" for CORS request. Inability to Specify a Custom Hostname If the default hostname returned by Liberty is not desired, any API request initiated from Swagger UI will use the incorrect hostname. This leads to the same error as above. (PH67460 at 17.0) -The Debug Profile Service (EQAPROF) fails to create a non-CICS profile (EQAUOPTS) in an SMS managed environment. The following error is logged in the error stream (STDERR) IGD17271I ALLOCATION HAS BEEN ALLOWED TO PROCEED FOR DATA SET IBMUSER.DLAYDBG.EQAUOPTS ALTHOUGH VOLUME COUNT REQUIREMENTS COULD NOT BE MET IGD17273I ALLOCATION HAS FAILED FOR ALL VOLUMES SELECTED FOR DATA SET This error occurs because the space units (TRACKS) is not explicitly specified during dataset allocation via BPXWDYN. In an SMS environment without a default for allocation units, ALLOC uses MB instead of TRACKS. This might lead to IGD17273I if MB allocations do not have sufficient volumes defined in the storage pool. (PH67659 at 17.0) For COBOL V5 and V6: FIXCAT KEYWORD: COB0501T/K COB0502T/K COB0601T/K COB0602T/K COB0603T/K COB0604T/K COB0605T/K For z/OS Debugger: FIXCAT KEYWORD: DEBUGGER/K --- End Service ---
