Symptom
The performance of the restore operation is slow. How can I speed it up?
Solution
The shared memory apportioned between the child and the oragentd parent process uses a multi-buffering queue to parallelize as much of the transferred data as possible during the restore. The default number of blocks is 80. You can increase the number of blocks and speed up restore operations by editing the agent.cfg file in the common agent directory. Assign the new value to CA_ENV_NUM_OF_REST_BUFF, then uncomment this variable and make it active with the command caagent update.
If you find that increasing the number of blocks does not help, you may want to try decreasing them instead. In some circumstances and on some platforms (such as OSF), reducing the number of blocks actually helped increase the performance. You will need to test different values to see what works for your particular situation.
