Documentum – Impact of Java 17 and JAVA_TOOL_OPTIONS

  • Starting with JDK 9, you may need to add some “–add-exports” or “–add-opens” parameters to the JAVA_TOOL_OPTIONS. With Java 17, it is fully in effect so you may start seeing some issues if you don’t have the correct configuration.
  • Documentum 23.2 and 23.4 added full support for JDK 17, but not defining JAVA_TOOL_OPTIONS when trying to install and run Documentum might result in some issues.
  • Installing the Documentum binaries without defining the JAVA_TOOL_OPTIONS doesn’t generate any errors or warnings, but it might cause a silent failure with the DFC installation.
  • Without JAVA_TOOL_OPTIONS, the DFC doesn’t get installed with the Documentum binaries but the rest looks good. Manually installing DFC would work.
  • Installing a Connection Broker without defining the JAVA_TOOL_OPTIONS doesn’t cause any issues, but connecting to it will require a DFC.
  • Trying to run the Repository installation without defining JAVA_TOOL_OPTIONS will cause the installation to quickly fail because of its dependency on DFC.
  • Defining JAVA_TOOL_OPTIONS is required for both the Documentum Server binaries and the Repository installation. It also helps at runtime with utilities such as dmqdocbroker/iapi/idql.
  • OpenText has included Java options in several places, but it's still not enough for a fully functional setup.
  • Overall, adding the correct Java options will help ensure a smooth installation and usage of Documentum.

Top 8 MySQL Schema Checks to Boost Database Performance

  • Defining Primary Keys help in optimizing query results. Lack of primary keys slows down replication performance, especially with row-based or mixed replication. The preferred Table Engine for most cases is InnoDB due to its superior performance, data recovery capabilities, and transaction support. InnoDB caches both data and indexes in memory, which is preferred for read-heavy workloads. Using different collations across tables or even within a table can lead to performance problems, particularly during string comparisons and joins. Mixed character sets can hurt join performance on string columns by preventing index use or requiring value conversions. Tables that are expected to grow indefinitely and use auto-increment for primary keys should use the UNSIGNED BIGINT data type. Foreign keys can impact database performance because each write operation requires additional lookups to verify the integrity of the related data. Remove Unused or Duplicated Indexes to streamline query optimization and reduce overhead. Unused indexes can negatively impact database performance by consuming disk space, increasing processing overhead and slowing down operations.
  • Primary Key Check (Missing Primary Keys)
  • Table Engine Check(Deprecated Table Engine)
  • Table Collation Check (Mixed Collations)
  • Table Character Set Check (Mixed Character Set)
  • Column Auto Increment Check(Type of Auto Increment Columns)
  • Table Foreign Key Check(Existence of foreign keys)
  • Duplicated Index Check
  • Unused Index Check
  • Releem now includes comprehensive schema health checks. These checks provide real-time insights into your database’s structural integrity, along with actionable recommendations for fixing any detected issues.

CHROs, here are five opportunities to lead the future of work

  • New data indicates that more than 90% of CEOs say HR should have a hand in developing an organisation’s future of work strategy.
  • However, in most cases, the people team is not leading the organisation’s future of work initiatives.
  • A September 2024 IBM Institute for Business Value and Oracle report identified a group of forward-thinking organisations that are already succeeding with their strategic approach.
  • IBM and Oracle found that what sets these organisations apart is their comprehensive planning approach.
  • These “visionary” organisations report immediate ROI from their future of work strategies.
  • HR leaders have a crucial role in shaping their organisation’s future of work strategy.
  • IBM and Oracle researchers predict that success will depend on HR’s ability to champion change, develop talent and create environments where both people and technology thrive.
  • Here are areas where CHROs and their teams can have an impact: Talent development and management, employee experience enhancement, technology integration, change management, and skill development.
  • Creating environments that support continuous learning and leveraging AI to provide personalised development opportunities are key.
  • The study highlighted the importance of recognising employees with natural potential.

How indexes power your database

  • Indexes are used in databases to retrieve information as fast as possible by providing an additional data structure that provides references to data in disk
  • The typical implementation of indexes use variations of the B-Tree data structure to store references to the pages
  • The binary search has logarithmic time complexity and is generally faster than linear complexity
  • Creating an index for a table means creating a separate table that includes mapped column data
  • The database would scan this index table rather than every row of the original table when a user tries to search for a specific column's value
  • In this article, we explored how indexes can power our databases and speed-up reading operations
  • We saw that indexes uses binary search instead of sequential access in full table scan, which increases its efficiency
  • Through the practical example, we understood how the database plans the query execution on tables with and without indexes
  • It is important to understand how to optimize our queries to retrieve information as fast as possible
  • This is crucial for databases with large datasets to avoid the traversal millions of rows when searching for a single user, etc

Why Jamie Dimon is Sam Altman’s biggest competitor

  • Investors have poured north of $30 billion into independent foundation model players focusing on the false grail of so-called artificial general intelligence (AGI). However, we believe the greatest value capture exists in what is called Enterprise AGI. Private enterprises will capture the majority of value in the race for AI leadership. This report will dig deep into the economics of foundation models and will analyze Enterprise AGI and the untapped opportunities that exist within enterprises.
  • The false grail of AGI is often associated with OpenAI Chief Executive Sam Altman, driven by the pursuit of machine business work better than humans. However, removing humans' involvement for decision-making is not as easy as it seems.
  • AGI in the enterprise is the ability gradually to learn and adapt white-collar work processes of the firm. Instead of one all-intelligent AGI, it is a swarm of modestly intelligent agents that can collectively augment human white-collar work. Nvidia CEO’s quotes also resonate with this idea of a directory of AIs, some digital, some biological, specialized and skilled, and just generally good at doing things. An all-knowing AGI may not be a viable scenario.
  • Private enterprises possess unique data and process advantage that is not in the public domain, which is the key ingredient for its competitive advantage. The proprietary knowledge specific to a business resides in the enterprise's data estate, with foundation models deriving from the transformer, differentiated solely by the data sets that train it.
  • LLMs are focused on scaling up its algorithm without recognizing that scaling up Models does not mean scaling their accuracy. The cost of scaling models is becoming unsustainable, and prices will drop like a rock. The investments going to foundation models are misguided, and the massive value capture exists in Enterprise AGI, which is a large opportunity for companies and most of the value created will accrue to these firms.
  • Citizen developers give agents goals and guardrails. But just as important, agents can generate plans with step-by-step reasoning that humans can then edit and iterate. Then the exception conditions become learnable moments to help get the agent further down the long tail the next time. Agents can learn from their human supervisors and learn from exceptions while in production. This is the opposite of traditional software where you want to catch and suppress bugs before production. This extension of what an agent can do can create a potentially learnable step to extend the long tail of activities and handle more edge cases.
  • Agents can change the economics of achieving that by observing and learning from human actions. The swarm of workflow agents, which are really specialized action models, collectively have the ability to learn and embody all that management knowhow and outperform the most advanced foundation model. The collective intelligence of those agents outperforms the singular intelligence in a frontier foundation model.
  • The enterprise automation opportunity is significant but requires specialized knowledge because each process is unique, and it takes more than an AI model to understand an enterprise's processes. The future of enterprise software must not only deliver transactional efficiency and productivity but also be capable of managing and analyzing the complexities of real-time business processes in a unified framework subject to operational, analytic and historical systems.
  • Though there are various emerging players exploring the integrated, process-driven source of truth, understanding the nuances of each approach will be critical to building applications that can capitalize on this integrated, process-driven source of truth. The future presents both challenges and a significant opportunity, setting the stage for a new era in enterprise applications, data orchestration, and process alignment.
  • Overall, we believe that Enterprise AGI provides a massive opportunity for companies, and most of the value created will accrue to these firms. Private enterprises will capture the majority of value in the race for AI leadership, underscoring the importance of Enterprises' ability to gradually learn and adapt white-collar work processes over an all-knowing AGI.
