Ans)SAP manages locks using lock table. The lock table contains all of the information related to locks like who is holding the lock and which locks are currently held etc. The size of the lock table can be specified by the SAP parameter enque/table_size. The size of the lock table limits the number of locks, lock owners and lock names. If this size is exceeded, then the lock table overflow occurs.
18). How to identify lock table overflow issue?
Ans)In SM21 transaction log and ST22 dumps, if you find any error messages like LOCK_TABLE_OVERFLOW, Lock table overflow, Internal lock administration error it means there is a lock table overflow issue.

22).What is the parameter to be changed to increase lock table size in SAP?
Ans)Parameter enque/table_size to be changed to increase or decrease lock table size using RZ10 transaction. Default value of this parameter is 32768. The min value that can be set is 4096 and max value is 102400. The unit for this parameter is KB.
23).How to change SAP parameter?
Ans)As this is not dynamic parameter, for the new value to take effect, a system restart is required after modifying the parameter.
24).What is the reason for lock table overflow?
Ans)A lock table overflow can occur due to:
- The lock table is configured too small (i.e value set to enque/table_size parameter is very low)
- Due to improper design of application which sets a large number of locks
- Number of enqueue worprocesses configured in a sap system is less and update is very slow/hanging due to which lots of locks are accumulated in lock table
- Running a custom report with improper selection criteria (like very long time periods data pull) which sets so many locks & eventually lock table overflow occurs
25).How to resolve lock table overflow?
Ans)Increase the size of lock table i.e increase the parameter enque/table_size value using RZ10 transaction. To determine the optimal value for this parameter, you can check the maximum locks set so far in the history and the current number of locks set from SM12 -> Extras -> Statistics
- Increase the number of enqueue workprocesses
Ans)Knowledge management is part of SAP NetWeaver Enterprise portal. Using Knowledge management, users can access unstructured information as per the role requirement from different data sources.

38).What are the post installation steps for SAP NetWeaver installation?
Ans)After the installation, you should remember the following points −
The installer creates the installation directory sapinst_instdir, this directory contains all the log files, and which is located directly in the %ProgramFiles% directory. If the installer is not able to create sapinst_instdir there, it tries to create sapinst_instdir in the directory defined by the environment variable TEMP.
There is a subdirectory created for each option and it is located in the sapinst_instdir directory as mentioned in previous step.
If you want to see the list of all available installer properties, you can go to this path- %TEMP%\sapinst_exe.xxxxxx.xxxx after you have started the installer and run the below statement:

Defining Transport Domain Controller
Configuring the SAP system landscape
Defining the Transport Routes among systems within the system Landscape
Distributing the configuration
40).What is the use of Transport Domain Controller?
Ans) This is used to manage all TMS configuration details. Any changes to configuration settings are distributed across all systems. To set up the Domain controller, use transaction code — STMS
In case, the SAP system doesn’t have a Domain Controller, you will be prompted to create a new one.
41).Which file stores the Transport Configuration details in Transport System?
Ans)DOMAIN.CFG file is created under usr/sap/trans/bin directory which stores TMS configuration and is used by systems and domains for checking existing configurations.
42).How do you add a system to Transport domain?
Ans)Step 1 - Log on to the SAP system, that you want to add as a System, in client 000 and enter the transaction code — STMS. If system is not added, TMS will check configuration file DOMAIN.CFG and will prompt you to create one. Click on — Select the Proposal and Save. The system will remain in ‘Waiting’ status initially.
To complete the task? login to the Domain Controller System → Transaction STMS → Go to Overview → Systems.
