A bash script for generating multiple STATSPACK reports.
GOAL

You can automate STATSPACK reports generation in the Oracle Database by using the dbs_gstatspack.sh bash script. The provided script simplifies the STATSPACK generation process when there is a need to generate multiple STATSPACK reports quickly for database analysis.

SOLUTION

The script is meant to generate multiple STATSPACK reports between 2 snap IDs. The script requires a begin snap ID, an end snap ID, the interval between snap IDs, and the directory path for storing generated reports.

s|start      - A begin SNAP ID 
e|end        - An end SNAP ID 
i|increment  - [Optional] A number of snapshots in a report. The default is 1.
d|directory  - [Optional] A directory for storing STATSPACK reports. The default is the script directory.
debug        - [Optional] Enables debug output when executing the script 

For instance

## To generate 1 STATSPACK report based on 5 snapshots 

./dbs_gstatspack.sh s=1 e=5 i=5 

## To generate 4 STATSPACK reports based on 2 adjacent snapshots each
## Snapshots ranges are 1-2, 2-3, 3-4, 4-5

./dbs_gstatspack.sh s=1 e=5 i=1 
NOTE

Convert the script from DOS text file format to UNIX text file format
