IBM DB2 UDB
IBM DB2 Universal Database (UDB) ServicesBelow is a sample of some of the DBA services we provide for IBM DB2 Universal Database (UDB) for Linux, UNIX, and Windows (LUW) environments under the Virtual-DBA Service or through Xtivia Professional Services:
We can make recommendations according to IBM's Best Practices on SAN Storage for your database running on AIX, HP-UX, Solaris, Linux or Microsoft Windows. These recommendations will include Logical Unit Number (LUN) sizes, RAID type, file system sizes, and where to place your data, indexes, and transaction logs to provide the best performance possible.
Poor Structured Query Language (SQL) statement performance and high CPU usage on your DB2 server almost always indicates the need for performance tuning. We can analyze your pain points and make recommendations on your DB2 configuration, memory settings, and storage architecture. We will also analyze poor performing SQL statements that may benefit from the correct index and in some cases a clustering index to drastically reduce the amount of CPU your database server needs to use. These efforts can be performed against specific targets or as part of our Health Check package for DB2
Allocating memory on your DB2 server can be a daunting task, especially for DB2 V8 running on 32 bit architecture. We can make recommendations on how to divide your available memory into the places DB2 needs it the most. Places like the bufferpools, sort heap, lock list, and utility heap. DB2 ESE, DB2 WSE and DB2 Express-C instances on 64 bit architecture have more memory to work with. We can help you take advantage of that extra memory and allocate it appropriately.
Upgrading your DB2 ESE or DB2 WSE instances to version 9 or 10? Maybe migrating from V9.5 to V10? Whatever versions you work with, migrating to a new version of DB2 takes planning and experience. We can handle all aspects of your DB2 upgrade on AIX, HP-UX, Solaris, Linux or Microsoft Windows including code installation, instance migration, database migration and licensing.
Are you ready to get your DB2 ESE or WSE system out from under the 32 bit memory limits? If you are planning a version upgrade or just want to take advantage of your 64 bit AIX, HP-UX, Solaris, Linux or Microsoft Windows operating system, we can help you migrate your DB2 ESE or DB2 WSE instance to take advantage of the 64 bit architecture on Linux, Unix and Windows.
Fixpacks for DB2 include important changes, known as APAR’s, to existing features and additional features that you should take advantage of. We can install the latest fixpack for your version of DB2 and help you take advantage of any new features
HADR stands for High Availability Disaster Recovery. HADR is a database replication feature that provides a high availability solution for both partial and complete site failures. HADR protects against data loss by replicating data changes from a source database, called the primary, to a target database, called the standby. We can implement HADR in your DB2 environment and show you how to manage it.
Starting with V9.1, DB2 comes with a new feature called STMM. We can help you fully take advantage of this feature to allow DB2 to handle memory allocation and allow you to work on other things.
Ever wonder if you are getting the most out of your DB2 ESE, WSE, or DWE database running on AIX, HP-UX, Solaris, Linux or Microsoft Windows? Our DB2 Health Check service will provide you with exactly what you need. We do a deep analysis of your environment, database workload, and database configuration to provide you an easy to read, management level report with the current state of your system and any recommendations to improve its performance and availability.
DB2 SQL Replication can be very useful for setting up a reporting database, a test database or even a High Availability fail-over database. DB2 SQL Replication comes standard with DB2 ESE and WSE, and DB2 Express. We can help you gather requirements, implement, and manage your replication solution.
The best solution for avoiding downtime and data loss in a production environment is to implement a preventive maintenance strategy before problems occur. We can work with you to identify potential problems, produce a course of action, and implement data security and recovery strategies that fit into your business plan.
We have assisted many clients experiencing performance, configuration or implementation issues with their DB2 environments. They have experienced issues with the DB2 system setup or configuration or one of the many available tools such as DB2 Connect, DB2 Query Patroller or DB2 Information Integrator. Normally an assessment by one of our DBAs leads to a suggested course of action that we can work with you to implement.
Very often the role of the DBA is overlooked in development efforts. We work with the development teams of many clients, either in the developer, DBA or architect roles. We can help with SQL writing and tuning, reviews of data models, performance, data modeling, and general best practices. With the Virtual-DBA service, you can get our DBA involved with your team as needed.
Today one of the biggest concerns around any database is security. We can assist you to insure that proper security is in place for your DB2 environment. We can work with you to identify potential problems, produce a course of action, and implement system security strategies that fit into your business model.
IBM Tivoli System Automation (TSA) is cluster managing software that facilitates automatic switching of users, applications, and data from one database system to another in a cluster. TSA is commonly used with DB2 High Availability Disaster Recovery (HADR) to automate the takeover of database operations from the primary HADR database server to the Standby database server in the event of a failure. We can implement both HADR and TSA to satisfy your Disaster Recovery requirements. Learn more about IBM TSA |
