This means that the script will cease execution if any error is encountered. If you encounter an error and you need to restart the script, just comment out the whenever sqlerror exit line and run the script again. Once you have completed running the spcreate.
To check for errors, you need to look for any lines that contain "ORA-" or the word "error", since the presence of these strings indicates an error. The code here shows the UNIX grep commands that are used to check for creation errors. Please check spctab. Please check spcusr. To ensure that everything is installed correctly, we can demand two snapshots and then request an elapsed-time report.
If we do this twice, we will have two snapshots, and we can run the statsrep. Here is the test to ensure that the install works properly. If you get a meaningful report after entering statsrep , then the install was successful. Also, note that the statsrep. By using the statsauto. The statsauto. If the DB server running very slow, then we need to perform DB tuning and it is very important to have an established baseline for later comparison. On the behalf of baseline data, we identify the performance problems.
The Statspack saved all the performance statistics permanently in the tables. The table data is used for reporting and analysis later. The Statspack reports collected data can be analyzed, which include a database instance health and load a summary page, high resource-consuming SQL statements, and the traditional wait events and initialization parameters.
A minimum of 64 MB space is required for the installation of statspack which is used for creating tables and indexes. In other words, you can say that the amount of space required by the statspack package and its depends on the recap of snapshots, the size of the DB and instance, and the range of data collected, which can be configured.
It is therefore difficult to provide unprivileged storage clauses and database space utilization predictions that are accurate at each site. This script calls these subscripts:. It prompts you for the start and end snapshots, and then produces an elapsed-time report.
