README
# 1. dbcollect
`dbcollect` help DBA to collecting database info, which later will be processed by [dbtools](https://marketplace.visualstudio.com/items?itemName=dbworker.dbtools), to auto check db's health and export reports.
Usually, for health-check task, DBA collecting info, checking info and writting reports(.doc) for each db manually.
Now, these tools help doing most of foundation work in health check:
- [dbcollect](https://github.com/dbworker/dbcollect) help collecting database info from many v$_* views, alert log, etc.
- [dbtools](https://marketplace.visualstudio.com/items?itemName=dbworker.dbtools) is a vscode's extension,
- help exporting many health check reports automatically;
- use **rule-based check**([dbtools-rule](https://github.com/dbworker/dbtools-rule/blob/main/oracle_rule.ini)), check database's health and show problems on vscode IDE.
For example, dbcollect will dump some data like this
```
...
```
dbtools use these xml data to check db's health(show in gif):
Currently dbcollect support Oracle(>= 11g) on (Linux, AIX).
# 2. How to use dbcollect
Download or clone dbcollect.git to you pc, then upload to database host (Linux or AIX) with 'oracle' user.
Open a terminal, login db host as user `oracle`, change to dbcollect folder
```
cd /path/to/dbcollect
```
then
- (1) Firstly change to `config/` directory and modify `*.toml` file, pls refer to example toml.
```
cd config
vi xxx.toml
```
- (2) If you run many instances or pdbs in one host, repeat step 1, one db by one toml file.
```
vi yyy.toml
```
- (3) change to dbcollect directory, run shell command
```
cd ..
sh hccdump.sh
```
If everything ok, after running you will get packed output file `*.tar.gz` in `data/` directory.
(Later you will download *.gz to your pc, unzip it, and open `dbtools` to process it.)

# 4. FAQ
## 4.1 Field meaning in config/*.toml
config/*.toml was used by dbcollect , then packed in dump file and transfer to dbtools.
(1)`customer` and `doctitle` used by dbtools to export doc
- export doc name is in form like "customer_doctitle.doc"
- doc first page will replace placeholder-tag using : customer, doctitle
- to avoid unrecognizable char(GBK,Japan), should use only ASCII char
```
customer="CMCBANK"
doctitle="TEST1_TESTDB1 Database Health Check Report" # must be unique, should be meaningful
```
(2) `db_alias` used as folder name by dbcollect to store dump file
- for manual reading, should be meaningful, and only ASCII char
- must be unique in customer's hundreds database
```
db_alias="TESTDB1" # used as meaningful folder name
# must be unique to distinguish from other db
```
(3) `ORACLE_SID` be used to connect to oracle
```
db_type="Oracle" # used by hccdump to fill in xml
ORACLE_SID="TESTDB1" # used by hccdump to connect to oracle
```
## 4.2 Output filename has unrecognizable char
Recommend use ASCII char in config file *.toml.
Don't use local language character set, such as GBK.
# 5. Known issues
currently v0.3.0 has some fault:
- on PDB, some values are same to CDB$ROOT (see example file lnx19c_pdb1.tar.gz).
- if database has large object number, some queries will slow
- HC_TABLE_USE_LONG
- HC_BIG_TABLES
(you can manually disable related sql on script)
# 6. Future plan
- refine PDB info
- item for flashback, v$recovery_area_usage
- top transaction (top sql already in AWR)
# 7. Release history
**v0.3.2 at 30-Seq-2022**
