Set the initialization parameters for the database instances
When creating each Oracle InForm Oracle Instance, use the following initialization parameters in the init.ora file.
Parameter | Production server values | Development server values |
---|---|---|
memory_target (starting values) |
Small trial: 1.5 GB Large trial: 10 GB Mega trial: 25 GB |
Up to 80% of memory available to the Oracle database |
db_block_size | 16384 | 16384 |
db_files | Database dependent. | Database dependent. |
open_cursors See Note 1. |
150 | 150 |
processes See Note 1. |
150 (or maximum number of concurrent processes) | 50 |
session_cached_cursors See Note 4. |
150 | 150 |
streams_pool_size | 200M | 200M |
job_queue_processes | 5 minimum: 1 job for each study (the job to update PF_HEARTBEAT table every minute in each study schema) and 1 job for each propagation, plus streams’ minimum requirement of 2 and Oracle MTS’s requirement of 1) | 5 minimum: 1 job for each study (the job to update PF_HEARTBEAT table every minute in each study schema) and 1 job for each propagation, plus streams’ minimum requirement of 2 and Oracle MTS’s requirement of 1) |

filesystemio_options See Note 3 |
SETALL | SETALL |
workarea_size_policy See Note 2. |
auto | auto |
parallel_max_servers | 3 | 3 |
optimizer_adaptive_features | FALSE | FALSE |
Note:
These parameters might need to be adjusted depending on the demands on the database that are created by the Oracle InForm application and Streams.Note:
Although AUTO is default, parameter is needed to ensure proper AMM functioning.Note:
Enables both direct I/O and asynchronous I/O where possible.Note:
Up to the value of the open_cursors parameter.Parent topic: Create database instances
