Setting JNDI property for Mobile Analytics Time To Live(TTL) value as days in Liberty Profile
Error seen when the time-to-live value (TTL) for MobileFirst Analytics documents is set with the unit of “days”. For example, when we set 90d for 90days in the JNDI value, it fails.
Setting TTL for MfpAppLogs in MobileFirst Analytics Server as below
<jndiEntry jndiName="analytics/TTL_MfpAppLogs" value="90d" />
throws following error:
ibm.mobile.analytics.server.node.elasticsearch.IndexManager E MSAN219E: Setting for TTL: MfpAppLogs has been set to an invalid TTL string. org.elasticsearch.ElasticsearchParseException: Failed to parse [90.0]
Version impacted: IBM MobileFirst Analytics Server 7.1
As per the details provided in Liberty documentation, jndiEntry for string literals is expected to be enclosed with single quotes. Without a single quote the value passed as a numeral followed by ‘d’ (eg: 90d) is assumed as double-precision floating point (i.e 90.0) by the Liberty Server.
- jndiEntry for TTL values are expected to be String literals.
- As per Liberty documentation TTL value should be passed with in single quotes.
- For example, setting TTL for MfpAppLogs in MobileFirst Analytics Server, it should look as follows (note the additional single quotes):
<jndiEntry jndiName="analytics/TTL_MfpAppLogs" value='"90d"' />
