NULL/EmptyString Item ID through DataManagementService.getNextIds(InfoForNext[])

NULL/EmptyString Item ID through DataManagementService.getNextIds(InfoForNext[])

Software Versions/Configuration:

========================================

Using Teamcenter 8.3.2.3_n01_p2 w/ CMM and NX7.5.5.mp7

Description of Problem:

========================================

When running large translations of catia to nx data through CMM, we are not receiving appropriate Tc Item ID assignment.

During CMM processing of a given catia model, as piece parts are created in Teamcenter (Tc Items), a request for a ID is made using the function DataManagementService.getNextIds(InfoForNextId[]). For the input parameter InfoForNextId, CMM is providing the pattern string, the typeName, and "item_id" indicating to generate an item id.

This function is either returning a NULL value or an Empty String (unclear which) and CMM is therefore "failing" to get a proper TcID number.

We believe this issue is related to concurrency on the system... currently creation of Items in teamcenter is happening at roughly 200 items per minute during this migration. During running at this pace we are seeing a lot of "retries" on locking the NameCounter object in the syslogs (snippet below)...

This leads us to believe that there is some limit of retries or time to obtain a TCID and if one is not gotten in that time/count then NULL/empty is returned by the DataManagementService.getNextIds(InfoForNextId[]) function... We're looking for clarification on this behavior and if there is a way to disable such a timeout so that retries just continue until a proper item_id is actually returned.

Not all runs of the function experience this failure, however all runs do make mention of the following in the tcserver syslog which further indicates that this is probably a locking/contention issue:

POM__handle_db_interface_fail 449 got a retry

Got a retry. Sleeping 5

POM__handle_db_interface_fail 500 unknown timeout 4001 now 5

Steps to Duplicate:

========================================

Create 10 items per minute from 20 different tcserver processes concurrently (total 200 per minute) over a period of time and you will see this issue occur eventually when the lock contention on the NameCounter begins to occur Siemens PLM believes that the problem you reported where running large translations of catia to nx data through CMM and not receiving an appropriate Teamcenter Item ID assignment is fixed in release Teamcenter 9.1.2_n01, Teamcenter 10.1 and Teamcenter 11.1.
