Error 720



Message text

Unable to allocate a procedure memory control descriptor. Please increase the value of the configuration parameter '%s' or try again when there is less activity on the system. 


For each memory structure allocated in procedure cache, whether it is for a PROC_HDR or just a chunk of procedure cache, there is a procedure cache memory control descriptor that is used to track procedure cache usage. Adaptive Server Enterprise has attempted to allocate the space for a procedure cache memory control descriptor from the procedure cache memory control pool and the allocation failed.


Usually the configuration parameter listed will be procedure cache size. Increasing the procedure cache size may allow a larger procedure cache memory control pool.

Additional information

If the MDA tables are in use, monitoring memory allocations may reveal all allocations prior to the one that failed. If after increasing the procedure cache size, this error continues to occur, a configurable shared memory dump (CSMD) on error 720 may assist in determining root cause. Information about CSMD can be found in the section “Other Useful Tasks” in the Troubleshooting and Disaster Recovery guide.
