MQCERTVPOL

MQCERTVPOL specifies the certificate validation policy used.

For more information about certificate validation policies in IBM MQ, see Certificate validation policies in IBM MQ.

This environment variable overrides the CertificateValPolicy setting in the SSL stanza of the client ini file. The variable can be set to one of two values:

ANY: Use any certificate validation policy supported by the underlying secure sockets library.
RFC5280: Use only certificate validation which complies with the RFC 5280 standard.

To set this variable, use one of these commands:

On Windows:
```
SET MQCERTVPOL= value
```
For UNIX and Linux systems:
```
export MQCERTVPOL= value
```

For IBM i:

ADDENVVAR ENVVAR(MQCERTVPOL) VALUE(value)
