DB2 LUW has two basic edition classifications Clients and Servers. Clients include drivers and full DB2 clients. Servers include both DB2 and DB2 Connect servers. DB2 Clients do not require a license to use when connecting to DB2 LUW servers. DB2 servers include DB2 client code and if no permanent license is installed the server functionality will be unavailable once the trial period expires but the client code may still be used. To license purchased DB2 LUW server products two licenses will need to be installed. One license referred to as the... [More]
Informix introduced the PSM (Primary Storage Manager); a new backup storage manager in version 12.10 that replaced the previous ISM (Informix Storage Manager). The PSM manages storage devices used for backup and restore requests that are issued by Onbar. This storage manager supports both serial and parallel processing for backup and restore requests. PSM is easier to set up and use, even in embedded environments. You just need to perform four simple steps to configure PSM and take an Onbar backup: Decide where you will create the PSM catalog....

100 Tech Tips: #86 What information is in the name of the db2fmp The db2fmp or DB2 Fenced Mode Process
is used to run untrusted external routines. These routines can be
created in a variety of languages and can be thread-safe (meaning it
is safe to run them in a multi-threaded db2fmp process with other
unrelated routines), or not thread-safe (meaning they will be run in
a single db2fmp process). The name of the db2fmp in the ps output
can be used to determine the language and thread-safeness of the
db2fmp. The name also indicates if... [More]

db2pd is a very powerful tool which can be used for troubleshooting many complex issue in DB2 like - high memory usage, locking issues, HADR, and collecting various statistics. It can also be used to find out a simple thing like how long the instance has been up. db2pd with a '-' option displays the uptime for an instance. It displays the number of days and hours the instance has been running. No database connection is required. $ db2pd - Database Member 0 -- Active -- Up 4 days 00:13:14 -- Date 2014-10-27-14.56.06.346538 If the... [More]
During crash recovery, if many load operations have to be replayed, then it might take a long time to complete. The load operation will keep the pending operations in transaction logs no matter if it is recoverable load or non-recoverable. These pending operations will be kept in transaction log just before the table status is changed back from "load in progress" state to "normal" state. If the crash recovery starting point - min(lowtranlsn, minbufflsn) is before load pending operations then db2 will have to replay... [More]
Inoperative DB2 Package: Packages in DB2, can be dependent on certain types of database objects such as tables, views, aliases, indexes, triggers, referential constraints and table check constraints. If a package is dependent on a database object (such as a table, view, trigger, and so on), and that object is dropped, the package is placed into an invalid state. If the object that is dropped is an UDF, the package is placed into an inoperative state. For an inoperative package, in the SYSCAT.PACKAGES system catalog view, the VALID column shows:... [More]
