How To Fix RSRCACHE017 - Number of attempts to set enqueue

SAP Error Message - Details

• Message type: E = Error

• Message class: RSRCACHE - Messages for OLAP Cache

• Message number: 017

• Message text: Number of attempts to set enqueue

What causes this issue?

To work with a cache entry, a process must set an enqueue, which prevent
s other processes from working with this entry. If the enqueue is
already used by another process, after several attempts are made to set
the enqueue, the function module returns a message indicating that the
enqueue cannot be set because it has already been assigned. When this
happens, the cache repeatedly attempts to set the enqueue using the
function module.
Using this parameter, you can specify how often the cache is to attempt
to set the enqueue for a process.
This parameter only applies to the cache modes cluster table, BLOB table
, and flat files (both application server dependent and cross
application server).

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message RSRCACHE017 - Number of attempts to set enqueue ?

  The SAP error message RSRCACHE017 indicates that there have been multiple unsuccessful attempts to set an enqueue in the resource cache. This typically occurs when there is contention for a resource, and the system is unable to acquire the necessary locks within a specified number of attempts.
  Cause:
  
  Resource Contention: Multiple processes or users are trying to access the same resource simultaneously, leading to contention.
  Long-running Transactions: If a transaction holds a lock for an extended period, it can prevent other transactions from acquiring the necessary locks.
  Deadlocks: Situations where two or more processes are waiting for each other to release locks can lead to this error.
  Configuration Issues: Incorrect configuration of enqueue settings or insufficient resources allocated for handling enqueues.
  
  Solution:
  
  
  Analyze Lock Situations:
  
  Use transaction codes like SM12 (to view and manage locks) and SM21 (to check system logs) to identify which processes are holding locks and causing contention.
  Check for long-running transactions that may be holding locks unnecessarily.
  
  
  
  Increase Retry Attempts:
  
  If the default number of attempts to set an enqueue is too low, consider increasing it in the system configuration. This can be done in the profile parameters (e.g., rdisp/max_wprun_time).
  
  
  
  Optimize Transactions:
  
  Review and optimize the code of transactions that frequently encounter this error. Ensure that locks are held for the shortest time possible.
  Implement proper error handling and retry logic in your ABAP programs to manage enqueue attempts more effectively.
  
  
  
  Monitor System Performance:
  
  Regularly monitor system performance and resource usage to identify potential bottlenecks.
  Use tools like ST03N (Workload Analysis) to analyze performance and identify areas for improvement.
  
  
  
  Check for Deadlocks:
  
  Investigate and resolve any deadlock situations that may be occurring. This may involve analyzing the application logic to ensure that locks are acquired in a consistent order.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional guidance.
