It is more hard to learn about other DB Engine Review collected by and hosted on G2.com.

IBM Db2 offers me performance, also stability when talking about a lot of data. Review collected by and hosted on G2.com.

perhaps its interface is not as intuitive as other databases Review collected by and hosted on G2.com.

It´s easy to use, the DB2 is easy to upgrade and manage, all instructions are well documented on the IBM knowledge portal and also the support of the software is awesome, they solve your problems when you have them. Review collected by and hosted on G2.com.

I had an issue after a reboot, where the domain of the server changed and the DB2 wasn´t functioning correctly, so we had to change the domain and the device was up and running, we didn´t why that happened. Review collected by and hosted on G2.com.

We are the user of IBM DB2 since very early v7. v8, now we are on v11+.

This product after v11+ is amazing ------

* for very large DB (which we are using) the exteded compressed columnar-tables partitioned DB env make the BLU acceleration so fast that our DW's ETL (also IBM product) & Reporting so fast

* the workloads for OLTP are high balanced/improved that make all combined jobs have an average higher performance

* the Nested Loop Join (NLJN) made SQL-Merge so fast that a parallel sort using much less memory. Amazing.

* installation and migration become much easier with altogether software delivery.

* the security even more amzing that extended native encryption from local key store upgraded to enterpise level (with using Key Manager, KMIP)

* overall tech support are making sense. Not bad.

We are preparing to upgrade to DB2 v12. So far, we are overally satisfy this product with using other IBM DB management tool like Datastage (ETL) etc. Review collected by and hosted on G2.com.

Still some bugs found with v11.1 (which mostly fixed in v11.5), eg. IT35682; IT39085; IT34931 we experienced. But IBM-Support clearly explained that and provied alternatives.

We hope IBM can develop some kind of GUI All-in-One management (Web based) software/platform for DBA (especially) just like Oracle-Enterprise-Manager. Though there are some 3rd-party software on the market like DBI for DB2 Gui management, we hope IBM can 'invent' own software that could be includeded into the DB2 database software itself (for save on licensing) Review collected by and hosted on G2.com.

IBM Db2 is excellent for high availability and disaster recovery strategies particularly with HADR and Q replication for near real-time failover. The row-level locking mechanism optimizes OLTP workloads, ensuring efficient concurrency control without excessive blocking. Review collected by and hosted on G2.com.

Db2’s cloud-native integration lags behind modern cloud-first databases like Aurora or Spanner. Although IBM provides Db2 on Cloud, its Kubernetes operator lacks the automation maturity seen in competitors like CockroachDB or YugabyteDB. Review collected by and hosted on G2.com.

I have been using for for almost 20 years. Started on the mainframe then moved to UNIX. I really like Performance and Stability of this product.

We used to had very serious power issue and a lot of boxes crashed, a couple Oracle server could not come up and there was no issue with db2 crash recovery. Review collected by and hosted on G2.com.

I would like db2 on Unix to include something like cold start option and include a native utility to analyze log files. Review collected by and hosted on G2.com.

Many utilities that facilitate usage, in addition to improving the performance of some tasks. Review collected by and hosted on G2.com.

Some tasks like traces are a bit complicated in addition to the need for IBM for reading and understanding. Review collected by and hosted on G2.com.

I have worked on 2 different SQL platforms previously (Microsoft and Adobe). I have been using DB2 for the past one year since I started working in the BFS domain. The best thing I like about DB2 is how seamlessly it integrates with COBOL program with just the use of a SQLCA section. Apart from the common select, update or insert another feature I really love is the cursor feature and fetch options. It helps to navigate the database and choose the exact plan number or ssn relevant to that COBOL code . Review collected by and hosted on G2.com.

Sometimes I came across compilation errors when I try to execute COBOL codes using the DCLGEN utility for DB2. Review collected by and hosted on G2.com.

Its ability to integrate with mainframe DB2 is seamless and the performance is too good with near zero down time. Review collected by and hosted on G2.com.

Tooling needs an improvement is what I feel. Review collected by and hosted on G2.com.
