Linux-UNIX: Db2-specific guardctl parameters
Use these guardctl parameters when configuring A-TAP for a Db2 database, Linux only.
Db2 (Linux only) required parameters
Example:
/usr/local/guardium/guard_stap/guardctl --db-user=db2inst1 --db-type=db2 --db-instance=dn0rh7x6 --db-version=10.5 store-conf
The script find_db2_shmem_parameters.sh, located in stap_directory/bin, outputs what the Db2 shared memory parameters defined in the Inspection Engines should be. Execute it either as root or Db2 user, using the syntax: find_db2_shmem_parameters.sh <instance name>. You can run it from any directory.
Note: Hyphen and underscore are interchangeable in the guardctl parameters.
| Required Parameter | Value | How to determine |
|---|---|---|
| db_user | Db2 username | Points to the DB instance user name |
| db_instance | Db2 instance name | $ db2 LIST DATABASE DIRECTORY |
| db_type | db2 | |
| db_version | The database version | As Db2 user: $ db2level |
Db2 (Linux only) optional parameters
| Optional Parameter | Value | How to determine | When is it required |
|---|---|---|---|
| db_home | Path where the DB version is installed | Same as db_base | |
| db_base | Database instance user home directory | Value for db_base must match the correct path DB instance user home directory. It cannot be ~DB_USER. | Where db_base is not same as db_home |
| db_bits | 32 or 64 | DB instance architecture (32 for 32-bit, 64 for 64-bit) | Required only if A-TAP is not able to recognize the architecture. |
| db2_shmsize | 131072 | Db2 shared memory size | When the value is different than the default |
| db2_c2soffset | 61440 | Db2 shared memory client area offset | When the value is different than the default |
| db2_header_offset | 20 | Db2 shared memory header offset | When the value is different than the default |
