APAR status
Closed as program error.
Error description
As the database connections are not explicitly closed, the Java garbage collector may not return the free handles to the pool fast enough to meet the demands for the next set of database connection requests . Under certain situations, such as invalidating a large number of products and categories as a result of rebuilding the search index, the database connection handles may run out. When the connections run out, the system may appear to hang or slow down as it cannot obtain the necessary connection to process traffic. Error messages relating to connecting to the database may also appear in the logs.
Local fix
Increase connection pool size so that the chances of exhausting the pool is reduced
Problem summary
USERS AFFECTED: The problem may impact WC v7 users, depending on the program being run at the time. Error messages relating to database connection failure may also appear in the system logs. PROBLEM ABSTRACT: Database connection handles are exhausted under heavy maintenance workload due to connection handles not being freed up fast enough BUSINESS IMPACT: Unable to invalidate a large number of products and categories as a result of rebuilding the search index . RECOMMENDATION:
Problem conclusion
This APAR contains the fix in Data Services Layer (DSL) to close the database connection explicitly (instead of relying on the Java garbage collector to free up the DB connection handle) to avoid the timing issue. ------------------------------------------------------------- The latest available maintenance information can be obtained from the Recommended Fixes for WebSphere Commerce technote: http://www.ibm.com/support/docview.wss?rs=3046&uid=swg21261296
