ttCacheInfo

The ttCacheInfo utility returns change-log table information for all Oracle Database tables cached in a cache group with autorefresh and information about Oracle Database objects used to track DDL statements issued on cached Oracle Database tables. The output provided by this utility is primarily intended for use by TimesTen customer support.

The same output is obtained by running the cacheInfo.sql script installed with TimesTen. See Installed SQL*Plus Scripts in Oracle TimesTen In-Memory Database Cache Guide.

Required Privilege

This utility requires no privileges.

Usage in TimesTen Scaleout and TimesTen Classic

This utility is supported in both TimesTen Classic and TimesTen Scaleout.

Syntax

ttCacheInfo  {-h | -help | -?}
ttCacheInfo  {-o OracleNetServiceName}
             {-d DSN}
             {-u CacheAdminUsername}

ttCacheInfo  [-p prompts_OraclePwd]

Options

If you set the CacheAdminWallet connection attribute to 0, the ttCacheInfo utility requires you to provide both the cache administration user name and password. Hence, only the instance administrator can successfully execute ttCacheInfo without specifying a password. See CacheAdminWallet.

If you set the CacheAdminWallet connection attribute to 1, the ttCacheInfo utility requires only the cache administration user name. It retrieves the registered password from the wallet that contains the credentials. Any user that is not the instance administrator must specify the -p option and enter the Oracle cache administration user password when prompted.

In TimesTen Scaleout, the Oracle Wallets are located on data instances. Therefore, you must always run the ttCacheInfo utility from a data instance.

The ttCacheInfo utility supports the options:

Option	Description
`-d`	The DSN of the database whose information is being returned.
`-h` `-help` `-?`	Prints a usage message and exits.
`-o`	The OracleNetServiceName on which to collect the information.
`-p`	If set, it indicates that `ttCacheInfo` should prompt for the Oracle cache administration user password.
`-u`	The cache administration user name.

Output

The following shows the ttCacheInfo output without the -p option

$ ttCacheInfo -o oracledb -u cacheadmin -d rep3a
