Hardware and software requirements for Db2 Text Search
Software platforms
Except for Solaris, Db2 Text Search is supported on all the Db2 server V11.1 supported platforms listed here: System requirements for IBM DB2 for Linux, UNIX, and Windows
The stand-alone Db2 Text Search server is available for all platforms listed here: https://www-01.ibm.com/marketing/iwm/iwm/web/pickUrxNew.do?source=swg-dm-db2accsuite. Cross-platform usage is supported. A Db2 database instance on these platforms can be configured to use a stand-alone Db2 Text Search server on a supported platform.
Hardware requirements
The minimum hardware requirements for Db2 Text Search are as follows:
| Db2 Text Search Server | Processor | RAM / Memory | Disk |
|---|---|---|---|
|
Integrated setup (In addition to Db2 database server requirements) |
2 dual-core 2.66 GHz | 4 GB | Including temporary working space, each text search index requires about four times the size of all documents that you want to index. For example, a text index on a column with 1 million rows of 1 KB text size needs about 4 GB of disk space. |
|
Stand-alone setup |
Actual disk space, memory, and processor consumption depends on a various factors such as the number of collections, the number of documents per collection, the number of concurrently indexed collections, the required indexing throughput, and the query load. For more information, see the Db2 Text Search capacity planning topics.
For recommended operating system user process resource limits on Linux and UNIX operating systems, see the topic about operating system user limit requirements. These general resource limit requirements apply to both the integrated and stand-alone setups of the Db2 Text Search server.
