Set Initialization Parameters
After the upgrade completes:
- Set the init.ora parameters. See Table 3-1 for parameter values.
- Stop and then start the database to activate the modified init.ora parameters.
Note:
Do NOT SET the DB_DOMAIN parameter. In Release 5.1 onward, this causes problems with the Patient Data Report generation.
If you set up the EVENT parameter in the init.ora file to trace unique key constraints before upgrading, you should set the event parameter back to its required value. See Table 3-1 for details.
If your init.ora file includes the REMOTE_OS_AUTHENT parameter, make sure that it is not set to TRUE. It can be set to FALSE or be absent.
Table 3-1 Required and Recommended Initialization Values in the init.ora File
Parameter | Value | Comments |
---|---|---|
COMPATIBLE |
19.3.0 |
Specifies the release with which the Oracle server must maintain compatibility. |
DB_BLOCK_SIZE |
16384 bytes |
You cannot change this value after you create the database. |
DB_CACHE_SIZE |
150 MB |
Recommended value for 50 to 60 concurrent users. Adjust this value according to your organization's needs. |
DB_DOMAIN |
null |
DO NOT set this value. In Release 5.1 onward, setting this value causes problems with the Patient Data Report generation. |
DB_FILES |
200 |
Oracle adds needed space to the control files up to the number specified in the DB_FILES parameter. |
EVENT |
31151 trace name context forever, level 0x100 |
Required for HTML generation. NOTE: Do not include the EVENT parameter when you create the database. Once the database is created, you can add the EVENT parameter to the init.ora file. |
JAVA_POOL_SIZE |
50 MB |
Recommended value for 50 to 60 concurrent users. You can change the value of this parameter after installation. Set this parameter to a value as per the number of concurrent users accessing the system. |
JOB_QUEUE_PROCESSES |
10 |
Developer-specific parameter. You can change the value of this parameter after installation. |
LARGE_POOL_SIZE |
50 MB |
Recommended value for 50 to 60 concurrent users. |
MEMORY_MAX_TARGET |
1000 MB (minimum) |
Adjust this value according to your organization's needs. |
MEMORY_TARGET |
1000 MB (minimum) |
Adjust this value according to your organization's needs. |
NLS_DATE_FORMAT |
DD-MON-RRRR (default value) |
Determines the format in which client applications running on the Windows server transfer date information to and from the database. The format must specify the year as RRRR. |

BYTE |
The CHAR value for this parameter is not supported. |
OPEN_CURSORS |
800 or greater |

FALSE |
Controls adaptive statistics. Some query shapes are too complex to rely on base table statistics alone, so the optimizer augments these statistics with adaptive statistics. |
OPTIMIZER_DYNAMIC_SAMPLING |

The default setting is 2. Oracle recommends using dynamic sampling for Batch Data Load temporary tables; see the Oracle Clinical Administrator's Guide. |
OPTIMIZER_FEATURES_ENABLE |
19.1.0 |
Acts as an umbrella for enabling a series of optimizer features based on an Oracle release number. |
PGA_AGGREGATE_TARGET |
