9.3 Workload Capture Restrictions
Certain types of user sessions and client requests may sometimes be captured in a workload, but they arenot supported by Database Replay. Capturing these session and request types in a workload may result in errors during workload replay.
The following types of user sessions and client requests are not supported by Database Replay:
Direct path load of data from external files using utilities such as SQL*Loader
Non-PL/SQL based Advanced Queuing (AQ)
Flashback queries
Oracle Call Interface (OCI) based object navigations
Non SQL-based object access
Distributed transactions
Any distributed transactions that are captured will be replayed as local transactions.
XA transactions
XA transactions are not captured or replayed. All local transactions are captured.
JAVA_XA
transactionsIf the workload uses the
JAVA_XA
package,JAVA_XA
function and procedure calls are captured as normal PL/SQL workload. To avoid problems during workload replay, consider dropping theJAVA_XA
package on the replay system to enable the replay to complete successfully.Database Resident Connection Pooling (DRCP)
Workloads using OUT binds
Multi-threaded Server (MTS) and shared server sessions with synchronization mode set to
OBJECT_ID
Migrated sessions
The workload is captured for migrated sessions. However, user logins or session migration operations are not captured. Without a valid user login or session migration, the replay may cause errors because the workload may be replayed by a wrong user.
Typically, Database Replay refrains from capturing these types of non-supported user sessions and client requests. Even when they are captured, Database Replay will not replay them. Therefore, it is usually not necessary to manually filter out non-supported user sessions and client requests. In cases where they are captured and found to cause errors during replay, consider using workload capture filters to exclude them from the workload.
