Not enough room in ROOT DBspace
Hi Jack, thanks for your response. I already created physical and logical log dbspaces, moved the physical log to that dbspaces and created the rest of the logical logs in the other dbspace. But I was wondering why the first dbspaces is the ROOTNAME Thanks…
Quickie question: Release 12.10: What is max size of physical log?
Before performing such a move to a new dbspace to store your physical log: 1/ Determine whether adequate contiguous space in the target chunk is available by running the oncheck -pe command before making the physical log move using onparams. …
Can we get the same output as onstat -g spa from SQL queries against sysmaster
Henri: Honestly, if you set SQLTRACE to LOW or MEDIUM and have a reasonable number of reasonably sized buffers configured, I have not seen any significant performance hit from turning SQLTRACE on. The single incident I did see was a client who crashed their host be configuring a …

Buffer wait occurs when performing INSERT in multiple sessions
You have to only peripherally related problems. The issue about not enough KAIO resources is an operating system tuning parameter. You can read the maximum value and set it here: $ cat /proc/sys/fs/aio-max-nr 65536 echo 131072 >/proc/sys/fs/aio-max-nr # set new maximum And see …
Number of extents
Amit: There is no problem or issue with having dbspaces with different pages sizes, no. There are advantages, including: Each page size gets its own buffer pool which can improve performance for busy tables and isolate them from affecting other tables. Indexes perform better on w…
DBINTERVAL
See Andreas's response, but I wanted to be clear, DRINTERVAL is NOT used to stop replication. The effect of setting DRINTERVAL to 0 depends entirely on the setting of HDR_TXN_SCOPE. It sets the replication mode to ASYNC, NEAR_SYNC, or FULL_SYNC depending on what HDR_TXN_SCOPE is …

Online Physical Log Question
I am working on a system experiencing slow database insert/select throughput (HP9000 Online 5). I believe part of the problem is a very small physical log file size - 1MB. (The logical logs are also small at 1/2MB). I have 2 questions: 1. What impact does the physical log fil…

Buffer manager
Hello! We are trying to model the delays in a database. To do this we need answers on the following questions. 1. If you have a number of SQL questions, how many percent of the needed datablocks is it likely that you have to get from the diskstorage?? 2. Does the answer from…

Experiences with organizing Raw-Devices
Are there any rules to organize a Raw-Device for an Informix-Database ? 1. In practice it is useful to place the physical- and logical-logs in the "rootdbspace". The Databases should be in separate "dbspaces". 2. The LOGspace and the DATAspace should be placed, if possible, …
