LMDB lock at Solution Manager 7.1 SP03

Hello everyone,

During the configuration of Solution Manger 7.1 SPS03 on Windows srv 2008 r2 SP1 x64 with DB2 LUW 97.FP4 we have an error after synchronization between SLD and LMDB.

When we check ABAP runtime error (ST22), every 10 minuts the same error occur:

A write or change lock was set on a transactional ABAP shared objects
  area and it has not yet been removed.
  Since the content of such areas should be synchronous with the database
  no open write or change locks may exist at the time of a database
  commit.

  In this case the lock is on:
  Area "CL_LMDB_MODEL_SHM_AREA",
  Client " ",
  Instance "LDB:0000000000".
  The lock was set at the following position:
  Program "CL_LMDB_MODEL_SHM_LOADER======CP" (Version 20100705094154),
  Code offset 100."

We check also tx. [SHMM:|http://pokazywarka.pl/wfoimn/]

I have changed ABAP parameter (abap/shared_objects_size_MB set to 400) in instance profile, but not help.

When I login to LMDB administration info is displayed:

LMDB Performance Indicators

Error occurred while detaching to LMDB Shared Memory

Namespace table LMDB_P_NAMESPACE contains several entries for value active.

LMDB Shared Memory Error CX_SHM_NO_ACTIVE_VERSION:The lock on the instance for area LDB:0000000000 of namespace active occured.

Any ideas, how to resolve the problem ?

Best Regards,

SAPFan

Hello SAPFAN,

The shared memory related runtime errors are a side-effect of

inconsistent entries in table LMDB_P_NAMESPACE. These inconsistencies

are caused by bug that has been fixed with SAP note 1638659.

If this note is already on your system the entries in LMDB_P_NAMESPACE must have been created before that time, in which case they can be fixed manually, but should be done by an expert, and I would recommend you open an message on SV-SMG-LDB if this is the case. Otherwise SAP Note 1638659 should address.

Hello Paul,

Thank you for reply. I`ve implemet note 1638659 before configuration of solution manager.

Table [LMDB_P_NAMESPACE|http://pokazywarka.pl/r74j1f/] have 4 entries. Which of them should I delete?

Best regards,
