PrerequisiteYou must be logged on as the root user.

Create a file, filename.txt, with one line for each cufconfig parameter whose value you want to change.
Each line has this syntax: parameter: value
For example:
- These lines change the memory and cache to the maximum values in Recommended Java Server Settings for BYOM Sessions:
```
ParallelUserServerAMPs: 50
ParallelUserServerPEs: 50
SecureServerAMPs: 120
SecureServerPEs: 120
JavaHybridThreads: 50
JavaServerTasks: 50
```
- This line increases the JVM memory size and the cache size:
```
JVMOptions: -Xms2048m -Xmx8192m -DcacheMaxLimit=3g
```
  The value of cacheMaxLimit is in GB.
  
  For more information about these parameters, see Configuration and Tuning Settings.
Run this command:
```
cufconfig -f filename.txt
```

Restart the system:

# tpareset -f force

  You are about to restart the database
  on the system 'S1'
  Do you wish to continue (default: n) [y,n] y

Check the new parameter values:
```
cufconfig -o | grep -iE 'parameter[|parameter]'
```
For example, to show the values of the parameters ParallelUserServerAMPs and ParallelUserServerPEs:
```
cufconfig -o | grep -iE 'paralleluserserveramps|paralleluserserverpes'
```
