No matter how confident you are regarding database management for your small to medium scale business, there is no guarantee that you will prevent server crashes in your organization. To prevent server crashes in your organization, you must know why they are caused first. Though you assume as a business owner, you are taking care of everything your database needs. There are some things that you might be missing out on.
Why do you need to partner with a good remote DBA company?
When it comes to performance tuning and effective database management, it is prudent for you to partner with a good remote DBA company to consistently monitor your system 24/7×365 days. There are several reasons for a database crash. Once your organization suffers from it, it can be hard for you to regain the trust of your customers, employees, and others that are associated with your company.
Skilled specialists in remote database management say the following are the key reasons that lead to server crashes, making it all the more necessary for you to hire remote DBA companies for curbing frequent instances of downtime –
- Poor maintenance for pre-deployment data scripts – This can take place because of-
- Databases have become destabilized, especially when they lack the required indexes and keys for mitigating response time and redundancy.
- The recent upgrades of the database and system software are not working well together, leading to low performance
- The planning of database configuration has not been managed properly.
- Your database is on the wrong server – Server hosting is highly competitive today. It is tempting for most business owners to configure their systems or plan for a system upgrade at lower prices. Suppose you are not careful with planning and strategy. In that case, your business database, along with critical information, will land up on a shared server, denying the end-user access to it when the network is full when it comes to shared usage of resources.
This takes place due to varied reasons like- flawed coding in the application, compromised database or application, poor query or configuration, and more. This results in the database being deficient when it comes to resources that deal with processing and memory.
3.The business application and its queries are hostile – This takes place when the layer for data access for your application if you have it, has not been programmed accurately. It results in slow queries or an overload of queries being issued. These queries are made when an over or underutilization of the table joins bi-directional in nature and indexes. This causes the indexes to become flawed and wasteful. They can even become absent. The above leads to poor quality design and the lack of quality standards, poor coding, and bad optimization queries.
4.Failures in hardware and software – Specialists from the esteemed company in database management and administration, Research say in the event of a power failure or failure in the host server’s hardware, your database will stop suddenly and crash. This is, of course, frightening, and it is here that you need to protect quality hardware and have a plan for power backup. You should ensure that the system’s maintenance is carried out rigorously to curb any database server crash.
5.The amount of swap space and memory is limited – The memory in a database relies on buffers, log files like data and index files, and caches. This buffer cache of the database is where the server duplicates the data from its files and places it for processing. As the volume of this data grows on the system, the file’s data grows as well. If you do not allocate equal memory for the in-house memory resources, the database system grabs the SWAP memory. Suppose there is inadequate SWAP space present. The server will stop the operations and subsequently crash due to insufficient memory.
6.File corruptions and permissions – Several database crashes are caused due to issues in file permissions, data that is corrupted, and index files. There are multiple reasons for the above-
- There was no correct locking when other database processes were modifying data or index that the database has written.
- The database processes are deploying the same directory for data located in the host system. They do not contain support for file system locking or locking of external files leading to the disability of the database servers.
- The server is attempting to read or write from an index or data file already corrupted or has crashed.
- Presence of a defective hardware component like an I/O corrupting an index or a data file.
- The absence of an expert and experienced DBA on the team – Database systems becomes flawed and fails when you do not have a skilled or proactive database administrator. The absence of such a professional on your IT team means you will not get the foresight or plan solutions for database performance effectively. Every DBA provider will take the onus to look after everything for you. They will check the integrity of the data, monitor its logs, catch issues and scale all your database system needs along with allocating space for database performance. This needs effective and constant planning and critical organization to curb system crashes that largely harm your database and business reputation and operations.
From the above, it is evident that when you take the above reasons for server crashes in mind, you will know how important it is for your business to partner up with a good remote DBA company. A credible company will offer you a complete range of remote DBA support and services. You should consult them for getting SQL, Oracle, etc., support as well.
Do not wait for your database system to fail and crash, instead take measures to prevent it. Consult credible remote DBA companies and help you reduce costs and boost your database maintenance tasks with success!
