What is the default validity period for a certificate, which is created by keytool on Impact 5.1.1, and can this period be adjusted.
The default period that a certificate created, by the Java's "keytool" utility, is only for 90 days.
The following URL describes how to create a certificate, which is needed to set up SSL communication on Impact 5.1.1, http://publib.boulder.ibm.com/infocenter/tivihelp/v8r1/topic/com.ibm.netcoolimpact.doc5.1.1/admin/imag_gui_server_generating_the_ssl_keystore_server_certificate_t.html.
If it's your desire to shorten or lengthen this period of time, you'll need to do so during the time of the certificate creation, with this option: "-validity #", where the # value is in days.
There may be other options, when using the keytool utility, which users may find useful. To see all the options please use "keytool -help", prior to creating your certificate.
