Error description
The following problem was originally reported against TWSz 8.5.1 by APAR PM56377 (CLOSED FIN). This APAR is created as the means to implement a fix for this problem in releases V8R6M0 and up. . When a TWSz-scheduled job defined with SUBMIT=NO is submitted outside of TWSz, it may be incorrectly tracked twice, against two separate scheduled occurrences, under the following conditions: 1. An occurrence of the application containing this job is in the current plan in READY status 2. A CP EXTEND process starts 3. While the CP EXTEND is running, the job is submitted. 4. The CP EXTEND adds another occurrence of the same with a LATEST START TIME *EARLIER* than the pre-existing occurrence. 5. The original application occurrence must not complete before the new current plan is brought into production. When this happens, the job is tracked "real time" against the originally scheduled occurrence, allowing that operation's SUCCESSORS to start. But then, when the new plan is brought into production and is brought up to date by applying the updates logged in the JTLogs while the CP was being created, the re- apply of JT events incorrectly associates the job with the NEWLY SCHEDULED occurrence. . The problem can be avoided by making certain that the LATEST START TIMES for operations tracking externally submitted jobs are always in INPUT ARRIVAL sequence. This can most easily be accomplished by assigning a valid operation-level deadline to the operation. . JT REAPPLY TURNOVER CATCHUP
