Some Notes on SNAPSHOT:# Using the GET SNAPSHOT command#Selecting from a snapshot table function

Use the Snapshot Monitor with the get snapshot command (discussed in Section 17.8, TheSnapshot Monitor) to get an accurate measurement of the number of transactions per minute ifthe database is already operational.

Specify the priority for the selected database on the Priority page (see Figure 17.8). If thedatabase is optimized for fast transaction processing, the database may take longer to recover inthe event of an error. If the database is optimized for fast recovery time, transaction performancenormally will be slower. If it is equally important to optimize both, choose to balance theoptimization of the two.---------------------------------

The GET SNAPSHOT command captures the requested snapshot information and writes theinformation to the screen or to an ASCII file.

You then need to examine the output of the snapshot for the information that you are looking for.

Since you access the snapshot table functions using SQL, you can select only the data you are interested in,

store the data quickly into a history table, and so on.

To get a snapshot for all of the activity on the database sample, you would issue the command:

# Using the GET SNAPSHOT commanddb2 "get snapshot for all on sample" | more

#Selecting from a snapshot table functionTo get the same information using the snapshot table function, you would use the statement:

db2 "SELECT * FROM TABLE(SNAPSHOT_DATABASE('SAMPLE',-1 )) as SNAPSHOT_DATABASE" > output.txt

You can then set the average number of active applications for the database sample based on thesnapshot information as follows:

db2 update db cfg for sample using avg_appls 10

===================================================================================================To find the Memory / Cache Hit Ratio/ Bufferpool Hit Ratios On !The cache hit ratio is one of the indicators used for tuning tasks. It Measures the percentage of hits in memory, specifically in the bufferpools (each of them).

To get the cache hit ratio for each buffer pool configured to run this query:+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

db2 "SELECT SUBSTR(DB_NAME,1,8) AS DB_NAME, SUBSTR(BP_NAME,1,14) AS BP_NAME,TOTAL_HIT_RATIO_PERCENT, DATA_HIT_RATIO_PERCENT,INDEX_HIT_RATIO_PERCENT FROM SYSIBMADM.BP_HITRATIO ORDER BY DBPARTITIONNUM"++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

This query shows the ratio for each cache buffer, separating between the ratio obtained with data blocks and index blocks.

If the value of this ratio is above 90%, it�s ok, if not: may indicate a problem with the memory size assigned to the instance.
