CHORNTSF Output Errors May Indicate Insufficient TSF Heap Memory

Symptom:

When I run the Time Series Facility (TSF) Server started task (CHORNTSF), I am getting the following errors in the CHORNTSF job output:

The TSF Server has encountered an Out Of Memory exception, and will now shut down.

java.lang.OutOfMemoryError

Solution:

The recommended TSF heap memory values are based on average system load per discipline. If the system load for your discipline differs from the average system load, your TSF heap memory allocation may be insufficient. To calculate the amount of TSF heap memory that a discipline requires, use one of the following equations.

Note: For the recommended TSF heap memory values, see the Administration Guide.

Follow these steps:

Determine the amount of load for your discipline:
- For CA Chorus for Security and Compliance Management, determine the Security entity instance count.
  
  Security entity instance
  
  Number of LPARs, plus the number of LPARs multiplied by the average number of CPF nodes per LPAR. If you do not know the the average number of CPF nodes per LPAR, use the default value of 30.
  
  Example: 12 + (12x30) = 372
- For CA Chorus for Storage Management, determine the Storage entity instance count.
  
  Storage entity instance
  
  Unique name of a dfSMS and non-dfSMS storage volume name, DASD volume name, catalog name, or data set group name that is registered in CA Vantage.
- For CA Chorus Infrastructure Management for Networks and Systems, determine the number of LPARs.
  
  LPARs
  
  Total system count across Sysplexes that Sysview monitors.
Calculate the TSF heap memory value for your discipline:

CA Chorus for Security and Compliance Management

To calculate the minimum TSF heap memory value:
```
0.0904x + 187.4 = minimum value, in MB
```
x

Number of entity instances that you determined in step 1.
To calculate the optimum TSF heap memory value:
```
0.1921x + 268.76 = optimum value, in MB
```
x

Number of entity instances that you determined in step 1.

CA Chorus for Storage Management

To calculate the minimum TSF heap memory value:
```
0.016x + 187.4 = minimum value, in MB
```
x

Number of entity instances that you determined in step 1.
To calculate the optimum TSF heap memory value:
```
0.034x + 268.76 = optimum value, in MB
```
x

Number of entity instances that you determined in step 1.

CA Chorus Infrastructure Management for Networks and Systems

To calculate the minimum TSF heap memory value:
```
4.812x + 187.5576 = minimum value, in MB
```
x

Number of LPARs that you determined in step 1.
To calculate the optimum TSF heap memory value:
```
10.225x + 270.0949 = optimum value, in MB
```
x

Number of LPARs that you determined in step 1.

You have calculated the TSF heap memory value for your disciplines.
