Problem summary
**************************************************************** * USERS AFFECTED: 1. All RSE and RSEAPI users when downloading * * dataset. * * 2. All RSE users. * * 3. Users operate dataset archive on * * tape from the GUI. * * 4. sysprog * * 5. All RSE users. * * 6. Users in a system with improper * * passticket configuration required to work * * with RSE. * * 7. Users disconnect when still running fast * * query for attributes of a large number of * * members for a dataset. * * 8. z/OS Explorer Client * * 9. z/OS sysprogs * **************************************************************** * PROBLEM DESCRIPTION: 1. When z/OS Explorer download dataset * * members, especially in high level of * * concurrency, RSEAPI raw content * * download may encounter this exception * * java.lang.NumberFormatException: For * * input string: " " * * at java.lang.NumberFormatException. * * forInputString(NumberFormatException. * * java:76) * * 2.Add the missing validation for input * * for fgets() call before using it in * * some of the RSE core functions. * * 3. RSE does not support active datasets * * on tape and is supposed to treat these * * datasets as offline to disable * * further operations on these datasets. * * It mistakenly includes also archive * * datasets on tape. * * 4. faulty default port in ivpinit.sh * * 5. If the *timeout* status of a * * ThreadPool is never reset, it will be * * automatically removed from Daemon's * * selection for ever. A new ThreadPool * * eventually will be needed to be spawn * * to handle new connection. * * 6.The RACF rc and rsn codes from * * passticket generation are not logged * * for further trouble shooting. * * 7. The long running query may still be * * running in the background when the user * * disconnects, causing the query using * * resource that might already been * * released by the disconnection. * * 8. The properties view for the job did * * not show system name provided by JMON. * * 9.zExpl 3.1.1.30 PTF UI74965 requires * * zExpl 3.2 / IDz 15.0 client for some * * enhancements * **************************************************************** 1. Catching the exception parsing an empty string for an integer. Reset to -1 as the initialized value for record count. 2. As from l standard for a software routine, input to some of the RSE backend routines, needs to be validated to avoid malicious usage from external caller entrance. 3. RSE mistakenly includes archived dataset on tape instead of only active datasets on tape. 4. faulty default port in z/OS Explorer ivpinit.sh 5. The *timeout* status of the ThreadPool should be reset when one of its connection is logging off as documented to optimize RSE performance avoiding unnecessary spawning of a new ThreadPool. 6. The original passticket error leads to a null pointer exception in parsing the result as the command is not executed. The logging of this exception is not helpful and may cause misleading. 7. The long running thread for the query does not get stop by the miner when it finish. The thread when using released resource cause the dump. 8. The properties view for the job should show system name provided by JMON instead of DNS name of the system you're connected to 9. IBM Explorer for z/OS 3.1.1.30 PTF UI74965 introduces support for JES-related enhancements, but did not mention these enhancements can only be used by zExpl 3.2 / IDz 15.0 clients. - "display active address spaces" requires client zExpl 3.2.0.16 / IDz 15.0.2 - "job requeue" requires client zExpl 3.2.0.17 / IDz 15.0.3
Problem conclusion
1. Parsing result should be resilient on the obtained result, including in error condition. The change improve that characteristic of the internal parser. 2. The validation helps to strengthen zRSE product security and behavior, especially in error condition. 3. In the active dataset on tape detection based on device type, check on volsers marked with archived keyword and leave them as is, then proceed with the rest as active datasets and treated them as offline. 4. corrected typo 5. Simply reset the ThreadPool's *timeout* status (by Daemon) by the end of the processing of connection log-off from the ThreadPool 6.Adding back the logging of rc, rsn of the original passticket error. Check on process execution environment before parsing the result to avoid the misleading null error logging. 7. Adding the cancelation callback to the query call, fired off by the MVS miner when it finishing. So that it can flag the running query thread to stop. Also, register the cancelable handle in the callback table, so it could receive the required cancelation request following up for the stop action on the query of a user from the GUI. 8. The fix will update the system name in the properties view of the running job to show the JMON system name. 9.updated closing information
