1, consider the data planning, storage space and so on. estimated by formula; character set, sort, page size cannot be changed after creation. data storage planning, especially for cluster mode deploymentLUN Plan Essentials. the disk used by IQ must be physically isolated from other applications;RAID 5/6don't use LVM .dispersing I/O as far as possible1. We recommend patching and building the library first. 2. Preparing the file systemIt is recommended to allocate a separate file system such as database log information (SERVERLOG/IQMSG) to avoid the log explosion. start_iq-n iqdemo iqdemo.db ... <other options> ...
-iqmsgsz 100-iqmsgnum 3 start_iq -n iqdemo iqdemo.db .... <other options> ... -iqmsgsz!--wizrtf2html charset=0-->A -iqmsgnum Value n greater than 0 means that the server maintains n message log Archi Ves. For example, this command specifies that the server maintain 3 archives of the message log
Use THE-IQMSGSZ and-iqmsgnum switches to prevent the message log file from growing indefinitely
-iqmsgsz (MB)
0 = default, which means there is no limit on the size of the message log file.
0 < x <= 2047, Limit on the size of the message log file.
-iqmsgnum
0 = default, which means that messages be wrapped in the main message log file and there is no archiving
0 < x <=, sets the number of message log archives
