[ https://issues.redhat.com/browse/ISPN-12124?page=com.atlassian.jira.plugi... ] Paul Ferraro updated ISPN-12124: -------------------------------- Description: The OracleTableManager limits the size of generated object names to 30 characters.  While 30 characters was the max object name length in 12.1 and earlier, since 12.2, this limit was increased to 128 characters. 30 characters is prohibitively restrictive when it come to objects like the index name, the names for which are auto-generated based on the cache name, table name, and, in the case of the segment column, a long hard coded prefix (e.g. "segment_index") uses up nearly half of the available characters. Rather than fixed lengths per database type, Infinispan should leverage the DatabaseMetaData to determine the max size for a given database object, e.g. getMaxTableNameLength(), getMaxColumnNameLength(), etc. was: The OracleTableManager limits the size of generated object names to 30 characters.  While 30 characters was the max object name length in 12.1 and earlier, since 12.2, this limit was increased to 128 characters. 30 characters is prohibitively restrictive when it come to objects like the index name, the names for which are auto-generated based on the cache name, table name, and, in the case of the segment column, a long hard coded prefix (e.g. "segment_index") uses up nearly half of the available characters. Ideally, Infinispan should determine the max object name size at runtime based on the values returned by the DatabaseMetaData, e.g. getMaxTableNameLength(), getMaxColumnNameLength(), etc. -- This message was sent by Atlassian Jira (v7.13.8#713008)
