Ensure that PFA finds the configuration file
Description
Before z/OS V2R2, Predictive Failure Analysis (PFA) required that you run the install script, AIRSHREP.sh, to create the new directory structure, copy the ini file, and create the default EXCLUDED_JOBS file. Beginning with z/OS V2R2, there is no need to run the install script. Everything previously done by the install script is now done when PFA starts. Also, the only ini file that PFA uses is the /etc/PFA/ini file. The install of PFA requires that any values in the /etc/PFA/ini file are correct.
Table 1 provides more details about this migration action. Use this information to plan your changes to the system.
Element or feature: | BCP. |

Is the migration action required? | Yes, if the /etc/PFA/ini file does not exist or if the values for JAVAPATH, PATH, and LIBPATH are not correct. |
Target system hardware requirements: | None. |
Target system software requirements: | None. |
Other system (coexistence or fallback) requirements: | None. |
Restrictions: | None. |
System impacts: | None. |

Steps to take
Before you begin, ensure that the PFA user has READ access to the /etc/PFA/ini file. Also, the operator must have proper authority to read or update the files, as needed.
When PFA is started, PFA attempts to use the values in the /etc/PFA/ini file.
- If the /etc/PFA/ini file already exists, PFA uses the existing JAVAPATH, PATH, and LIBPATH that are in the file. Update the values as necessary.
- If the /etc/PFA/ini file file does not exist, PFA attempts to create the /etc/PFA/ini file file from an existing check, or it uses the values defined in the /usr/lpp/bcp/samples/PFA/ini file. To ensure that the JAVAPATH, PATH, and LIBPATH values are correct for your installation before PFA starts, copy /usr/lpp/bcp/samples/PFA/ini into /etc/PFA/ini and update the values as necessary.
PATH= /usr/lpp/java/J7.1/lib/s390/classic:/usr/lpp/java/J7.1/lib/s390
LIBPATH=/usr/lpp/java/J7.1/lib/s390:/usr/lpp/java/J7.1/lib/s390/classic:/lib:/usr/lib:
If the values are not correct, PFA either fails to start or can have processing errors.
